False Dichotomy and Bad Science

Someone shared with me a link to a genetics study. The paper is “Behavioural individuality in clonal fish arises despite near-identical rearing conditions” by David Bierbach, Kate L. Laskowski, and Max Wolf. From the abstract:

“Behavioural individuality is thought to be caused by differences in genes and/or environmental conditions. Therefore, if these sources of variation are removed, individuals are predicted to develop similar phenotypes lacking repeatable individual variation. Moreover, even among genetically identical individuals, direct social interactions are predicted to be a powerful factor shaping the development of individuality. We use tightly controlled ontogenetic experiments with clonal fish, the Amazon molly (Poecilia formosa), to test whether near-identical rearing conditions and lack of social contact dampen individuality. In sharp contrast to our predictions, we find that (i) substantial individual variation in behaviour emerges among genetically identical individuals isolated directly after birth into highly standardized environments and (ii) increasing levels of social experience during ontogeny do not affect levels of individual behavioural variation. In contrast to the current research paradigm, which focuses on genes and/or environmental drivers, our findings suggest that individuality might be an inevitable and potentially unpredictable outcome of development.”

Here is what this seems to imply. We don’t as of yet understand (much less are able to identify, isolate, and control) all of the genetic, epigenetic, environmental, etc factors that causally affect and contribute to individual development. Not only that but we don’t understand the complex interaction of those factors, known and unknown. To put it simply, our ignorance is much more vast than our knowledge. We don’t even have enough knowledge to know what we don’t know. But we are beginning to realize that we need to rethink what we thought we knew.

It reminds me of the mouse research where genetically identical mice in environmentally identical conditions led to diverse behavioral results. I’ve mentioned it many times before here in my blog, including a post specifically about it: Of Mice and Men and Environments (also see Heritability & Inheritance, Genetics & Epigenetics, Etc). In the mice post, along with quoting an article, I pointed to a fascinating passage from David Shenk’s book, The Genius in All of Us. Although I was previously aware of the influence of environmental conditions, the research discussed there makes it starkly clear. I was reminded of this because of another discussion about mice research, from Richard Harris’ Rigor Mortis with the subtitle of “How Sloppy Science Creates Worthless Cures, Crushes Hope, and Wastes Billions” (pp. 79-81):

“Garner said that mice have great potential for biological studies, but at the moment, he believes, researchers are going about it all wrong. For the past several decades, they have pursued a common strategy in animal studies: eliminate as many variables as you can, so you can more clearly see an effect when it’s real. It sounds quite sensible, but Garner believes it has backfired in mouse research. To illustrate this point, he pointed to two cages of genetically identical mice. One cage was at the top of the rack near the ceiling, the other near the floor. Garner said cage position is enough of a difference to affect the outcome of an experiment. Mice are leery of bright lights and open spaces, but here they live in those conditions all the time. “As you move from the bottom of the rack to the top of the rack, the animals are more anxious, more stressed-out, and more immune suppressed,” he said.

“Garner was part of an experiment involving six different mouse labs in Europe to see whether behavioral tests with genetically identical mice would vary depending on the location. The mice were all exactly the same age and all female. Even so, these “identical” tests produced widely different results, depending on whether they were conducted in Giessen, Muenster, Zurich, Mannheim, Munich, or Utrecht. The scientists tried to catalog all possible differences: mouse handlers in Zurich didn’t wear gloves, for example, and the lab in Utrecht had the radio on in the background. Bedding, food, and lighting also varied. Scientists have only recently come to realize that the sex of the person who handles the mice can also make a dramatic difference. “Mice are so afraid of males that it actually induces analgesia,” a pain-numbing reaction that screws up all sorts of studies, Garner said. Even a man’s sweaty T-shirt in the same room can trigger this response.

“Behavioral tests are used extensively in research with mice (after all, rodents can’t tell handlers how an experimental drug is affecting them), so it was sobering to realize how much those results vary from lab to lab. But here’s the hopeful twist in this experiment: when the researchers relaxed some of their strict requirements and tested a more heterogeneous group of mice, they paradoxically got more consistent results. Garner is trying to convince his colleagues that it’s much better to embrace variation than to tie yourself in knots trying to eliminate it.

““Imagine that I was testing a new drug to help control nausea in pregnancy, and I suggested to the [Food and Drug Administration (FDA)] that I tested it purely in thirty-five-year-old white women all in one small town in Wisconsin with identical husbands, identical homes, identical diets which I formulate, identical thermostats that I’ve set, and identical IQs. And incidentally they all have the same grandfather.” That would instantly be recognized as a terrible experiment, “but that’s exactly how we do mouse work. And fundamentally that’s why I think we have this enormous failure rate.”

“Garner goes even further in his thinking, arguing that studies should consider mice not simply as physiological machines but as organisms with social interactions and responses to their environment that can significantly affect their health and strongly affect the experiment results. Scientists have lost sight of that. “I fundamentally believe that animals are good models of human disease,” Garner said. “I just don’t think the way we’re doing the research right now is.”

“Malcolm Macleod has offered a suggestion that would address some of the issues Garner raises: when a drug looks promising in mice, scale up the mouse experiments before trying it in people. “I simply don’t understand the logic that says I can take a drug to clinical trial on the basis of information from 500 animals, but I’m going to need 5,000 human animals to tell me whether it will work or not. That simply doesn’t compute.” Researchers have occasionally run large mouse experiments at multiple research centers, just as many human clinical trials are conducted at several medical centers. The challenge is funding. Someone else can propose the same study involving a lot fewer animals, and that looks like a bargain. “Actually, the guy promising to do it for a third of the price isn’t going to do it properly, but it’s hard to get that across,” Macleod said.”

This is the problem with the framing debate as nature vs nurture (or similar framings such as biology vs culture and organism vs environment). Even when people are aware of the limitations of this frame, the powerful sway it holds over people’s minds causes them to continually fall back on them. Even when I have no interest in such dualistic thinking, some people feel it necessary to categorize the sides of a debate accordingly, where apparently I’m supposed to play the role of ‘nurturist’ in opposition to their ‘biology’ advocacy: “feel your life-force, Benjamin. Come with me to the biology side!” Well, I have no desire to take sides in a false dichotomy. Oddly, this guy trying to win me over to the “biology side” in debate (about human violence and war) is the same person who shared the clonal fish study that demonstrated how genetics couldn’t explain the differences observed. So, I’m not entirely sure what he thinks ‘biology’ means, what ideological commitments it represents in his personal worldview.

(As he has mentioned in our various discussions, his studies about all of this are tied up with his experience as a father who has struggled with parenting and a husband who is recently separated, partly over parenting concerns. The sense of conflict and blame he is struggling with sounds quite serious and I’m sympathetic. But I suspect he is looking for some kind of life meaning that maybe can’t be found where he is looking for it. Obviously, it is a highly personal issue for him, not a disinterested debate of abstract philosophy or scientific hypotheses. I’m starting to think that we aren’t even involved in the same discussion, just talking past one another. It’s doubtful that I can meet him on the level he finds himself, and so I don’t see how I can join him in the debate that seems to matter so much to him. I won’t even try. I’m not in that headspace. We’ve commented on each other’s blogs for quite a while now, but for whatever reason we simply can’t quite fully connect. Apparently, we are unable to agree enough about what is the debate to even meaningfully disagree about a debate. Although he is a nice guy and we are on friendly terms, I don’t see further dialogue going anywhere. *shrug*)

When we are speaking of so-called ‘nature’, this doesn’t only refer to human biology of genetics and physiology of development but also includes supposed junk DNA and epigenetics, brain plasticity and gut-brain connection, viruses and bacteria, parasites and parasite load, allergies and inflammation, microbiome and cultured foods, diet and nutrition, undernourishment and malnutrition, hunger and starvation, food deserts and scarcity, addiction and alcoholism, pharmaceuticals and medicines, farm chemicals and food additives, hormone mimics and heavy metal toxicity, environmental stress and physical trauma, abuse and violence, diseases of affluence and nature-deficit disorder, in utero conditions and maternal bond, etc. All of these alter the expression of genetics, both within a single lifetime of individuals and across the generations of entire populations.

There are numerous varieties of confounding factors. I could also point to sociocultural, structural, and institutional aspects of humanity: linguistic relativity and WEIRD research subjects, culture of trust and culture of honor, lifeways and mazeways, habitus and neighborhood effect, parenting and peers, inequality and segregation, placebos and nocebos, Pygmalion effect and Hawthorne effect, and on and on. As humans are social creatures, one could write a lengthy book simply listing all the larger influences of society.

Many of these problems have become most apparent in social science, but it is far from limited to that area of knowledge. Very similar problems are found in the biological and medical sciences, with the hard sciences having clear overlap with the soft sciences considering social constructions get fed back into scientific research. With mostly WEIRD scientists studying mostly WEIRD subjects, it’s the same WEIRD culture that has dominated nearly all of science and so it is WEIRD biases that have been the greatest stumbling blocks. Plus, with what has been proven from linguistic relativity, we would expect that how we talk about science will shape the research done, the results gained, the conclusions made, and the theories proposed. It’s all of one piece.

The point is that there are no easy answers and certain conclusions. In many ways, science is still in its infancy. We have barely scratched the surface of what potentially could be known. And much of what we think we know is being challenged, which is leading to a paradigm change that we can barely imagine. There is a lot at stake. It goes far beyond abstract theory, hypothetical debate, and idle speculation.

Most importantly, we must never forget that no theory is value-neutral or consequence-free. The ideological worldview we commit to doesn’t merely frame debate and narrow our search for knowledge. There is a real world impact on public policy and human lives, such as when medial research and practice becomes racialized (with a dark past connecting race realism and genetic determinism, racial hygiene and eugenics, medical testing on minorities and the continuing impact on healthcare). All of this raises questions about whether germs are to be treated as invading enemies, whether war is an evolutionary trait, whether addiction is biological, whether intelligence is genetic, whether language is a module in the brain, and whether the ideology of individualism is human nature.

We have come to look to the body for answers to everything. And so we have come to project almost every issue onto the body. It’s too easy to shape scientific theory in such a way that confirms what we already believe and what is self-serving or simply what conforms to the social order. There is a long history of the intentional abuse and unintentional misuse of science. It’s impossible to separate biology from biopolitics.

Worse still, our imaginations are hobbled, making it all that more difficult to face the problems before us. And cultural biases have limited the search for greater knowledge. More than anything, we need to seriously develop our capacity to radically imagine new possibilities. That would require entirely shifting the context and approach of our thinking, maybe to the extent of altering our consciousness and our perception of the world. A paradigm change that mattered at all would be one that went far beyond abstract theory and was able to touch the core of our being. Our failure on this level may explain why so much scientific research has fallen into a rut.

I’ve been thinking about this for a long time. My thoughts here aren’t exactly new, but I wanted to share some new finds. It’s a topic worth returning to on occasion, as further research rolls in and the experts continue to debate. I’ll conclude with some more from Richard Harris’ Rigor Mortis. Below that are several earlier posts, a few relevant articles, and a bunch of interesting books (just because I love making long lists of books).

Rigor Mortis:
How Sloppy Science Creates Worthless Cures, Crushes Hope, and
Wastes Billions

by Richard Harris
pp. 13-16

There has been no systematic attempt to measure the quality of biomedical science as a whole, but Leonard Freedman, who started a nonprofit called the Global Biological Standards Institute, teamed up with two economists to put a dollar figure on the problem in the United States. Extrapolating results from the few small studies that have attempted to quantify it, they estimated that 20 percent of studies have untrustworthy designs; about 25 percent use dubious ingredients, such as contaminated cells or antibodies that aren’t nearly as selective and accurate as scientists assume them to be; 8 percent involve poor lab technique; and 18 percent of the time, scientists mishandle their data analysis. In sum, Freedman figured that about half of all preclinical research isn’t trustworthy. He went on to calculate that untrustworthy papers are produced at the cost of $28 billion a year. This eye-popping estimate has raised more than a few skeptical eyebrows—and Freedman is the first to admit that the figure is soft, representing “a reasonable starting point for further debate.”

“To be clear, this does not imply that there was no return on that investment,” Freedman and his colleagues wrote. A lot of what they define as “not reproducible” really means that scientists who pick up a scientific paper won’t find enough information in it to run the experiment themselves. That’s a problem, to be sure, but hardly a disaster. The bigger problem is that the errors and missteps that Freedman highlights are, as Begley found, exceptionally common. And while scientists readily acknowledge that failure is part of the fabric of science, they are less likely to recognize just how often preventable errors taint studies.

“I don’t think anyone gets up in the morning and goes to work with the intention to do bad science or sloppy science,” said Malcolm Macleod at the University of Edinburgh. He has been writing and thinking about this problem for more than a decade. He started off wondering why almost no treatment for stroke has succeeded (with the exception of the drug tPA, which dissolves blood clots but doesn’t act on damaged nerve cells), despite many seemingly promising leads from animal studies. As he dug into this question, he came to a sobering conclusion. Unconscious bias among scientists arises every step of the way: in selecting the correct number of animals for a study, in deciding which results to include and which to simply toss aside, and in analyzing the final results. Each step of that process introduces considerable uncertainty. Macleod said that when you compound those sources of bias and error, only around 15 percent of published studies may be correct. In many cases, the reported effect may be real but considerably weaker than the study concludes.

Mostly these estimated failure rates are educated guesses. Only a few studies have tried to measure the magnitude of this problem directly. Scientists at the MD Anderson Cancer Center asked their colleagues whether they’d ever had trouble reproducing a study. Two-thirds of the senior investigators answered yes. Asked whether the differences were ever resolved, only about a third said they had been. “This finding is very alarming as scientific knowledge and advancement are based upon peer-reviewed publications, the cornerstone of access to ‘presumed’ knowledge,” the authors wrote when they published the survey findings.

The American Society for Cell Biology (ASCB) surveyed its members in 2014 and found that 71 percent of those who responded had at some point been unable to replicate a published result. Again, 40 percent of the time, the conflict was never resolved. Two-thirds of the time, the scientists suspected that the original finding had been a false positive or had been tainted by “a lack of expertise or rigor.” ASCB adds an important caveat: of the 8,000 members it surveyed, it heard back from 11 percent, so its numbers aren’t convincing. That said, Nature surveyed more than 1,500 scientists in the spring of 2016 and saw very similar results: more than 70 percent of those scientists had tried and failed to reproduce an experiment, and about half of those who responded agreed that there’s a “significant crisis” of reproducibility.

The batch effect is a stark reminder that, as biomedicine becomes more heavily reliant on massive data analysis, there are ever more ways to go astray. Analytical errors alone account for almost one in four irreproducible results in biomedicine, according to Leonard Freedman’s estimate. A large part of the problem is that biomedical researchers are often not well trained in statistics. Worse, researchers often follow the traditional practices of their fields, even when those practices are deeply problematic. For example, biomedical research has embraced a dubious method of determining whether results are likely to be true by relying far too heavily on a gauge of significance called the p-value (more about that soon). Potential help is often not far away: major universities have biostatisticians on staff who are usually aware of the common pitfalls in experiment design and subsequent analysis, but they are not enlisted as often as they could be. […]

A few years ago, he placed an informal wager of sorts with a few of his colleagues at other universities. He challenged them to come up with the most egregious examples of the batch effect. The “winning” examples would be published in a journal article. It was a first stab at determining how widespread this error is in the world of biomedicine. The batch effect turns out to be common.

Baggerly had a head start in this contest because he’d already exposed the problems with the OvaCheck test. But colleagues at Johns Hopkins were not to be outdone. Their entry involved a research paper that appeared to get at the very heart of a controversial issue: one purporting to show genetic differences between Asians and Caucasians. There’s a long, painful, failure-plagued history of people using biology to support prejudice, so modern studies of race and genetics meet with suspicion. The paper in question had been coauthored by a white man and an Asian woman (a married couple, as it happens), lowering the index of suspicion. Still, the evidence would need to be substantial. […]

The University of Washington team tracked down the details about the microarrays used in the experiment at Penn. They discovered that the data taken from the Caucasians had mostly been produced in 2003 and 2004, while the microarrays studying Asians had been produced in 2005 and 2006. That’s a red flag because microarrays vary from one manufacturing lot to the next, so results can differ from one day to the next, let alone from year to year. They then asked a basic question of all the genes on the chips (not just the ones that differed between Asians and Caucasians): Were they behaving the same in 2003–2004 as they were in 2005–2006? The answer was an emphatic no. In fact, the difference between years overwhelmed the apparent difference between races. The researchers wrote up a short analysis and sent it to Nature Genetics, concluding that the original findings were another instance of the batch effect.

These case studies became central examples in the research paper that Baggerly, Leek, and colleagues published in 2010, pointing out the perils of the batch effect. In that Nature Reviews Genetics paper, they conclude that these problems “are widespread and critical to address.”

“Every single assay we looked at, we could find examples where this problem was not only large but it could lead to clinically incorrect findings,” Baggerly told me. That means in many instances a patient’s health could be on the line if scientists rely on findings of this sort. “And these are not avoidable problems.” If you start out with data from different batches you can’t correct for that in the analysis. In biology today, researchers are inevitably trying to tease out a faint message from the cacophony of data, so the tests themselves must be tuned to pick up tiny changes. That also leaves them exquisitely sensitive to small perturbations—like the small differences between microarray chips or the air temperature and humidity when a mass spectrometer is running. Baggerly now routinely checks the dates when data are collected—and if cases and controls have been processed at different times, his suspicions quickly rise. It’s a simple and surprisingly powerful method for rooting out spurious results.

Over the years breathless headlines have celebrated scientists claiming to have found a gene linked to schizophrenia, obesity, depression, heart disease—you name it. These represent thousands of small-scale efforts in which labs went hunting for genes and thought they’d caught the big one. Most were dead wrong. John Ioannidis at Stanford set out in 2011 to review the vast sea of genomics papers. He and his colleagues looked at reported genetic links for obesity, depression, osteoporosis, coronary artery disease, high blood pressure, asthma, and other common conditions. He analyzed the flood of papers from the early days of genomics. “We’re talking tens of thousands of papers, and almost nothing survived” closer inspection. He says only 1.2 percent of the studies actually stood the test of time as truly positive results. The rest are what’s known in the business as false positives.

The field has come a long way since then. Ioannidis was among the scientists who pushed for more rigorous analytical approaches to genomics research. The formula for success was to insist on big studies, to make careful measurements, to use stringent statistics, and to have scientists in various labs collaborate with one another—“you know, doing things right, the way they should be done,” Ioannidis said. Under the best of these circumstances, several scientists go after exactly the same question in different labs. If they get the same results, that provides high confidence that they’re not chasing statistical ghosts. These improved standards for genomics research have largely taken hold, Ioannidis told me. “We went from an unreliable field to a highly reliable field.” He counts this as one of the great success stories in improving the reproducibility of biomedical science. Mostly. “There’s still tons of research being done the old fashioned way,” he lamented. He’s found that 70 percent of this substandard genomics work is taking place in China. The studies are being published in English-language journals, he said, “and almost all of them are wrong.”

pp. 182-183

Published retractions tend to be bland statements that some particular experiment was not reliable, but those notices often obscure the underlying reason. Arturo Casadevall at Johns Hopkins University and colleague Ferric Fang at the University of Washington dug into retractions and discovered a more disturbing truth: 70 percent of the retractions they studied resulted from bad behavior, not simply error. They also concluded that retractions are more common in high-profile journals—where scientists are most eager to publish in order to advance their careers. “We’re dealing with a real deep problem in the culture,” Casadevall said, “which is leading to significant degradation of the literature.” And even though retractions are on the rise, they are still rarities—only 0.02 percent of papers are retracted, Oransky estimates.

David Allison at the University of Alabama, Birmingham, and colleagues discovered just how hard it can be to get journals to set the record straight. Some scientists outright refuse to retract obviously wrong information, and journals may not insist. Allison and his colleagues sent letters to journals pointing out mistakes and asking for corrections. They were flabbergasted to find that some journals demanded payment—up to $2,100—just to publish their letter pointing out someone else’s error.

pp. 186-188

“Most people who work in science are working as hard as they can. They are working as long as they can in terms of the hours they are putting in,” said social scientist Brian Martinson. “They are often going beyond their own physical limits. And they are working as smart as they can. And so if you are doing all those things, what else can you do to get an edge, to get ahead, to be the person who crosses the finish line first? All you can do is cut corners. That’s the only option left you.” Martinson works at HealthPartners Institute, a nonprofit research agency in Minnesota. He has documented some of this behavior in anonymous surveys. Scientists rarely admit to outright misbehavior, but nearly a third of those he has surveyed admit to questionable practices such as dropping data that weakens a result, based on a “gut feeling,” or changing the design, methodology, or results of a study in response to pressures from a funding source. (Daniele Fanelli, now at Stanford University, came to a similar conclusion in a separate study.)

One of Martinson’s surveys found that 14 percent of scientists have observed serious misconduct such as fabrication or falsification, and 72 percent of scientists who responded said they were aware of less egregious behavior that falls into a category that universities label “questionable” and Martinson calls “detrimental.” In fact, almost half of the scientists acknowledged that they personally had used one or more of these practices in the past three years. And though he didn’t call these practices “questionable” or “detrimental” in his surveys, “I think people understand that they are admitting to something that they probably shouldn’t have done.” Martinson can’t directly link those reports to poor reproducibility in biomedicine. Nobody has funded a study exactly on that point. “But at the same time I think there’s plenty of social science theory, particularly coming out of social psychology, that tells us that if you set up a structure this way… it’s going to lead to bad behavior.”

Part of the problem boils down to an element of human nature that we develop as children and never let go of. Our notion of what’s “right” and “fair” doesn’t form in a vacuum. People look around and see how other people are behaving as a cue to their own behavior. If you perceive you have a fair shot, you’re less likely to bend the rules. “But if you feel the principles of distributive justice have been violated, you’ll say, ‘Screw it. Everybody cheats; I’m going to cheat too,’” Martinson said. If scientists perceive they are being treated unfairly, “they themselves are more likely to engage in less-than-ideal behavior. It’s that simple.” Scientists are smart, but that doesn’t exempt them from the rules that govern human behavior.

And once scientists start cutting corners, that practice has a natural tendency to spread throughout science. Martinson pointed to a paper arguing that sloppy labs actually outcompete good labs and gain an advantage. Paul Smaldino at the University of California, Merced, and Richard McElreath at the Max Planck Institute for Evolutionary Anthropology ran a model showing that labs that use quick-and-dirty practices will propagate more quickly than careful labs. The pressures of natural selection and evolution actually favor these labs because the volume of articles is rewarded over the quality of what gets published. Scientists who adopt these rapid-fire practices are more likely to succeed and to start new “progeny” labs that adopt the same dubious practices. “We term this process the natural selection of bad science to indicate that it requires no conscious strategizing nor cheating on the part of researchers,” Smaldino and McElreath wrote. This isn’t evolution in the strict biological sense, but they argue the same general principles apply as the culture of science evolves.

    There are many interesting directions to take with this. One point I like to make is how recent is the world we live in. Nation-states with clearly demarcated boundaries of geography and citizenship, specifically of the ethno-nationalist variety, is a modern creation. Ancient people didn’t think that way.

    It turns out that even the genetics for light skin (along with hair and eyes) is a relatively recent adaptation, an evolutionary blink of the eye:

    http://www.sciencemag.org/news/2015/04/how-europeans-evolved-white-skin

    The earliest genes for light skin didn’t show up until about 8,000 years ago, more than 30,000 years after humans first arrived in Europe. It still took several more thousand years after that for light skin to spread across the continent. That was a slow process. Even so, the genetically oldest population, the Basque, remain darker-skinned to this day.

    Evolutionary pressures were obviously quite low. I suppose this is because humans are so talented at adapting culturally without the necessity of major genetic changes. Plus, epigenetics is able to alter gene expression in diverse ways allowing many possibilities with the same genes.

    Now consider this:

    https://benjamindavidsteele.wordpress.com/2016/05/15/building-and-battling-in-ancient-europe/

    There was no major large-scale war in Northern Europe until the collapse of the Bronze Age. Radical changes were happening in diverse societies around 1200 BC. At that point, humans had been in Northern Europe a long time. They managed to develop light skin about 5,000 years before they managed to develop serious capacity for war, at least in terms of what shows up in the archaeological record.

    Why is that?

    It’s not that there wasn’t violence during the Bronze Age. But apparently it was a different variety than the organized violence of standard warfare, or at least that was the case in Northern Europe. To complicate it further, according to Johan Ling (“Violence, Warriors, and Rock Art in Bronze Age Scandinavia” from Feast, Famine or Fighting?), “the war-related figurative rock art appear and vanish with the Bronze Age (BA). There are, interestingly, no war related figurative rock from the Neolithic era (4300-1700 BC) in Scandinavia.”

    So, why is evidence of a large-scale battle only found after the collapse of the Scandinavian societies that made art portraying violence? Even though they were raiding and such, there is no indication that they were overly interested in all-out warfare. As far as we know, the fighting portrayed in their art was mostly ritualistic combat, rarely leading to actual harm and death. It reminds me of some early American elections, as described by Edmund S. Morgan in Inventing the People (pp. 200-202):

    “The charges that each side flung at the other in an election were expected to be extravagant. Things were said and done that would not be permitted at another time, and it was bad form to take serious offense at them, though occasionally someone did. At a Maryland election in 1786 one candidate found the other’s denunciation of him so offensive that he challenged him to a duel afterwards. The challenge was accepted, but the person challenged expressed his surprise “that a man should be called out for anything that passed at an election.” 76 Everybody was supposed to know that electioneering invective was not for real.

    “Even the violence at the polls, while real enough to intimidate, had something of a ritual quality about it and was not to be held against a man when the election was over. […] Fighting to kill was not part of the script. Seldom do we find any mention of firearms in the accounts of violence. There might be clubs and cleavers but not guns, there might be bruises and blood, but no dead bodies. If anyone was dangerously injured it was by accident. Hence the reluctance of the courts to punish those at fault; election brawls were not to be taken seriously once the election was over.

    “From all the evidence it seems clear that brawling, violence, and intimidation were an accepted and expected part of an election and that it was understood they would end when the election ended. The violence of the election was a temporary, one-time thing and was probably not in fact as violent as it seems from the extravagant charges and countercharges that the two sides flung at each other. It was not quite for keeps. It was partly mock violence, partly make-believe, a routine that engaged the participants only temporarily and ended abruptly when the election was over.”

    Yet if all we had was a painting of those ‘violent’ elections, we’d likely conclude that they were deadly affairs and not mere symbolic politics. And such a conclusion would be wrong. So, we can’t read too much into rock art portraying what, from our cultural biased view, we would interpret as violence.

    We know so little about the ancient world. And I’d add, there is no reason to assume that tribal societies today can tell us anything about the earliest societies. Even the first city-states didn’t seem to fight all that much, certainly not in the way we think of as war today.

    It’s hard to even figure out what war meant to them, since according to extant accounts it was mixed up so much symbolic ritual. There is much debate about how much killing actually happened in ancient warfare or even more recent tribal warfare, as there seems to be many differences in the historical and anthropological record. For example, in the most ancient city-states, there was no such thing as a highly organized military with a strict chain of command that would march into war. Presumably, battles were mostly small-scale and short-term conflicts.

    I had a discussion about what war would have been like in what Jaynes hypothesises as bicameral societies:

    https://benjamindavidsteele.wordpress.com/2016/11/07/beyond-that-there-is-only-awe/#comment-24436

    Advanced warfare didn’t become common until the use of the chariot spread in the last centuries of the Bronze Age. And that was long after the first civilizations came on the scene.

    https://en.wikipedia.org/wiki/Horses_in_warfare

    Chariot warfare is a possible contributing factor to the collapse of Bronze Age civilizations. All of a sudden mass slaughter became easier to accomplish, not to mention faster form of travel with horses. This paved the way for the larger empires in the following millennia which further increased the potential of high death counts.

    Still, that doesn’t really explain what changed. The capacity to kill large numbers of people is not the same thing as the desire or need to do so. The domestication of the horse happened thousands of years before that. Why did large, complex war take so long to be invented and become dominant? People fought before that, but maybe it was a simple change in conditions. Population density was much lower at an earlier time such that there was less opportunity and motivation for conflict.

    The first known human settlement with permanent structures is Göbekli Tepe:

    https://benjamindavidsteele.wordpress.com/2017/05/21/first-came-the-temple-then-the-city/

    And apparently there is no evidence of organized violence. Göbekli Tepe was a temple built during the last Ice Age, prior to settled housing, agriculture, domestication of livestock, and pottery. These early humans organized to build a place of worship before they organized to do much of anything else we associate with civilization, including organized warfare. As Klaus Schmidt put it, “First came the temple, then the city”

    http://www.religiousstudiesproject.com/podcast/ara-norenzayan-on-big-gods-how-religion-transformed-cooperation-and-conflict/

    “That is to say, and from this point of view, that religion was not merely a result of the transformation from a hunter-gather lifestyle to a more sedentary, agricultural, domicile based life – it was the very catalyst. Or, as Norenzayan puts it, “religion transformed cooperation and conflict”.”

    https://en.wikipedia.org/wiki/G%C3%B6bekli_Tepe#Interpretation

    “It is also apparent that the animal and other images give no indication of organized violence, i.e. there are no depictions of hunting raids or wounded animals, and the pillar carvings generally ignore game on which the society depended, such as deer, in favor of formidable creatures such as lions, snakes, spiders, and scorpions. Expanding on Schmidt’s interpretation that round enclosures could represent sanctuaries…”

    http://advances.sciencemag.org/content/3/6/e1700564.full

    “Scalping is well attested in the anthropological literature, referring to the violent removal of scalp and hair (44). Scalping is often associated with warfare and trophy-taking; best-known examples are attested in prehistoric North America (45, 46). A special pattern of cut marks on the skull of the victim serves as evidence for scalping. Cut marks often occur in small clusters that form a rough circle around the skull (on the frontal, the parietal, and the occipital) (45). Despite the high fragmentation of the Göbekli Tepe skulls, the preserved fragments did not show the typical arrangement of cut marks associated with scalping.”

    http://www.npr.org/sections/parallels/2014/10/24/358577089/in-southeast-turkey-a-long-history-of-bloodshed-and-worship

    “One of the pleasures Clare has working on the cutting edge of archaeology is the freedom to speculate about the hunter-gatherers just before their transition to settlements — a people so focused on daily survival that there was no time, let alone a reason, to wage war. Clare says this period is notable for the lack of evidence pointing to conflict, which may seem surprising.

    “”But at the same time other scholars have said for the Neolithic to spread as it did, for this knowledge to spread, it would’ve needed people cooperating and not fighting,” he says. “And I think that’s a nice thought.”

    “That’s an almost utopian thought, considering the millennia of carnage that followed, including the blood still being shed in the 21st century, just across the Syrian border, a mere 20 miles away.”

    Interestingly, the earliest evidence for organized violence wasn’t until a couple of thousand years after Göbekli Tepe. It was a new era following the Ice Age. Humans were developing settlements, agriculture, pottery, etc. It could be simply that they now had something to fight and kill over, in that they had possessions of great enough value to be worth the risk to take by force.

    https://phys.org/news/2016-01-evidence-prehistoric-massacre-history-warfare.html

    “The Nataruk massacre is the earliest record of inter-group violence among prehistoric hunter-gatherers who remained largely nomadic. […] “These human remains record the intentional killing of a small band of foragers with no deliberate burial, and provide unique evidence that warfare was part of the repertoire of inter-group relations among some prehistoric hunter-gatherers,” she said. “The Nataruk massacre may have resulted from an attempt to seize resources – territory, women, children, food stored in pots – whose value was similar to those of later food-producing agricultural societies, among whom violent attacks on settlements became part of life,” said Mirazon Lahr.”

    All in all, there doesn’t seem to be a single pattern of violence or peace for all societies and at all times. Even within the same population, there are changing conditions of social stability and conflict. Plus, conflict isn’t always dealt with through mass organized violence or necessarily violence at all… or else only through symbolic/ritualized violence. At other times, populations can act violently for little if any reason at all. But there does seem to be some general pattern across certain eras, for whatever reason.

    It is a mystery. And based on our limited knowledge, it likely will remain a mystery.

    “based on your attitude it sure will! LOL”

    I’ve always been attracted to mysteries, but I’ve also always been attracted to knowledge. They go together in my mind. That is because, as people know more, they know more about what they don’t know. It’s just the nature of reality that there will always be more that we don’t know than what we do know. There is no getting around that, whether or not one chooses to acknowledge it.

    You seem to have misunderstood my comment. I wasn’t directly disagreeing or contradicting what you wrote. My comment was approaching from an angle, neither arguing against your view nor arguing for the opposite.

    “You really like all those notions of a peaceful past, huh?”

    Not really, to be honest. If you read my comment carefully, you’d see my point is that there is no conclusive evidence one way or another. We have no reason to assume that humans are inherently violent or inherently peaceful. Going by the evidence, it appears to depend on conditions: environment, resources, demographics, culture, technology, etc. That was the takeaway message from my comment.

    If I was nostalgically romanticizing a peaceful past, then I wouldn’t be looking at it as a mystery. The point is that I don’t know, as no one knows. Yet the evidence we do have is intriguing and should be carefully considered, especially when it challenges our cultural biases and ideological assumptions. Mysteries can be useful when they force us think more deeply and broadly, to shake loose the cobwebs in our mind and to consider new possibilities.

    It’s obvious from various research that much of what was taken as true in the past has since been proven false, partial, inadequate, or confused. I often cover this issue in my own blog, which of course you read. Take the WEIRD as an example. Almost all of the social science research has been done on WEIRD populations. And almost all the test subjects are a narrow segment of those societies, mostly undergraduates who are white Americans. It turns out that further social science research has shown this is possibly the least representative population on the planet.

    That is problematic, considering that almost the entire Western understanding of human nature is based on this research. We are talking about hundreds of thousands of studies done over more than a century, and we are barely coming to terms with the implications. A ton of research will have to be redone to see if the same results will be found in other populations. So far, it has been found there is more diversity in human societies than was originally believed. This is because culture, language, etc has more influence over human cognition and behavior than was previously understood.

    Much of the mystery involved is simply our present state of ignorance. Not all of that ignorance is inevitable. We simply got caught up in a reality tunnel or, to put it in a different way, a memetic mind virus took hold.

    “I don’t necessarily mind them either, I mean my idea is we make ourselves into this war ape consciously – maybe we only started doing it in the Bronze Age, I’m not certain it’s primal.”

    Here is one point that caught my attention. I should have made it clear, but I wasn’t sure what it meant.

    The early Bronze Age wasn’t particularly violent, as far as I know. But the late Bronze Age became increasingly violent, until nearly all of the major civilizations fell over like dominoes. I suggested that this might have to do with chariots. Jaynes connected it to the breakdown of the bicameral mind and connected this to certain cultural factors, such as the spread of writing systems.

    Whatever the case, Northern Europe apparently had something different going on. In the last centuries of increasingly serious warfare in the Bronze Age world of the Mediterranean and Levant, there is no evidence of major warfare in Northern Europe. The first large-scale battle of professional fighters didn’t happen until that very moment when the Bronze Age was coming to an end. Before that, why didn’t any of the mass organized violence further South make its way North?

    I have no answer for that. It was the same period of time. Maybe there was something different about the cultures or environments. It’s not that the North lacked violence, but it seems to have been more common varieties of violence, not warfare. Then after the Bronze Age ended, even the portrayals of violence in Scandinavia stopped being made. Scandinavians were long-distance traders and so maybe the disruption of trade routes caused them to become more isolated.

    The point is that even at around the same time there were diverse patterns of violence and non-violence from one place to another. What was actually going on and why is unclear.

    “I don’t need there to always have been war for the processes I’m talking about to be real”

    Another point I’d make is the following. There doesn’t always need to be any single thing for the multiple processes (shown in the known evidence) to be ‘real’. When speaking about what is ‘real’ in terms of human nature, we are speaking of vast complicated potentials that can and do express in innumerable and unpredictable ways, sometimes in completely opposite ways.

    “I never mentioned any level of organization or the size of any wars.”

    I brought that up for a reason. It’s partly a limitation of the data. When looking at the records (historical, archaeological, and anthropological), it’s easier to find evidence for the most obvious forms of violence. A group of people killed with weapons and buried together can be seen when the bones are dug up. But if ancient people regularly beat their children, it likely wouldn’t be easy to detect.

    Even though you didn’t bring it up, that doesn’t lessen its significance to the discussion. No large-scale violence that was organized and hence intentional has yet to be found prior to 10,000 years ago. That is a a massively fascinating fact.

    We have found communal burial caves Neanderthals used, the oldest organized activity by hominids in the world. And those Neanderthals lived short brutal lives, because of the dangerous animals they hunted. But there is no evidence that Neanderthals fought with each other or fought with humans. The only evidence we do have is that Neanderthals, humans, and other hominids occasionally had sex for hundreds of thousands of years.

    “If it is as old as us and chimpanzees, then the chimp battles that Goodall and others have witnessed are organized enough for my purposes.”

    We’ve discussed this before.

    The chimps Goodall observed were living in area under the stress of immense violence from civil war and poaching, along with the further stress of ecosystem destruction. These chimps weren’t living under normal conditions. It’s like basing your understanding of human nature on the observations of humans in a war zone. The probability that those chimp battles were normal chimp behavior is fairly low.

    Just across the river, there are the genetically similar bonobos. They live not only in a different place but under different conditions because of the humans in that area. There social structure, relationships, and behavior is also different — besides being non-aggressive and non-violent, they are matriarchal and sex-obsessed. We as of yet no genetic explanation for these differences, as the genetics differences are so minute. It’s possible that most of these differences are some combination of epigenetics and what in humans we would call culture, as influenced by different factors.

    This connects to something else we’ve discussed. The non-violent Piraha maybe unsurprisingly have lived in a non-violent area partly because contact with outsiders has been minimal which has allowed them to maintain their traditional culture, lifestyle, and natural resources. And the nearby violent Yanomami maybe unsurprisingly have lived in a violent area because of it being a border region between two countries and because of gold miners invading their territory. In his book Yanomami Warfare, R. Brian Ferguson wrote:

    “Although some Yanomami really have been engaged in intensive warfare and other kinds of bloody conflict, this violence is not an expression of Yanomami culture itself. It is, rather, a product of specific historical situations: The Yanomami make war not because Western culture is absent, but because it is present, and present in certain specific forms. All Yanomami warfare that we know about occurs within what Neil Whitehead and I call a “tribal zone”, an extensive area beyond state administrative control, inhabited by nonstate people who must react to the far-flung effects of the state presence.”

    For a good overview:

    https://en.wikipedia.org/wiki/Yanomami#Violence

    Why is it surprising that non-violent conditions tend to create non-violent behavior and violent conditions violent behavior? To me that doesn’t seem like a radical insight. And there is little mystery involved, even as mystery can be found in other aspects.

    “Some of the views I see when you talk about the ancient world sound more like legend, like the Australian Aboriginal “before time” or something, more of an internal, psychological history and not so much an historical one.”

    Well, it’s just what we know. Don’t argue with me. Argue with the historians, archaeologists, etc. It’s just what the evidence shows. What we do with the evidence is another issue. But dismissing the evidence as ‘legend’ because it is inconvenient to your WEIRD worldview is not helpful.

    I share your WEIRD worldview, as it is also what I was born into. I shared many common WEIRD beliefs about human nature and society, until I started studying it all more thoroughly. Much of what I’m discussing here is material that I came across in recent years. For the first several decades of my life, I was as ignorant about all of this as anyone else. Coming across new info shook up my world and challenged so much that I took as true. I’m still in the process of coming to terms with it all and still the challenging info keeps coming, as researchers have pushed the boundary of knowledge further and further, with no end in sight.

    We are in the middle of a paradigm change and no one can be sure what new compelling paradigm will form. It could turn out that both of us are wrong about many things. It’s more clear at this moment what we don’t know. But it’s hard to assess what is true according to what we don’t know.

    A year from now, new findings could turn everything on its head, forcing us to reassess and reinterpret large swaths of data. As scientists realize precisely what they don’t know, they are turning their attention to these former blindspots, these areas of ignorance and confusion. That is what happened with linguistic relativity. Some evidence showed that the status quo view didn’t fully make sense and so they began looking for ways to study what had been previously ignored. They had to first realize there was something unknown before they could about trying to know what was actually going on.

    When we see a lack of evidence of violence at the earliest human construction, that absence of evidence is not simply a mystery but an invitation to further knowledge. If the earliest humans figured out to organize to build things before they learned how to organize to kill each other, that is an important detail. Either further evidence will corroborate this or challenge it. But it makes clear that there is something of relevance going on here that we don’t understand and that might further challenge what we assume we know.

    Göbekli Tepe has already done that. It was assumed that religion followed and hence was caused by humans creating permanent settlements, agriculture, pottery, etc. The possibility that religion or whatever we are to call it came first is one of the greatest discoveries ever made. It forces us to rethink not only what is religion and civilization but what does it mean to be human. That this site also lacked evidence of violence further throws our assumptions into the air.

    This are serious. This is the stuff of science, not of legend. Even the experts in these fields aren’t entirely sure what to make of it all.

    BENJAMIN DAVID STEELE
    July 9, 2017 / 8:32 am
    I really don’t see us as disagreeing. We are just coming from different directions. Nothing I’ve said is necessarily problematic toward your views on violence and warrior culture. We both generally agree about the issues of behaviors, violent or otherwise, in relation to cultures and social conditions. Of course, the devil is in the details and that is where it gets complicated. It’s also in the details where it gets most interesting.

    Besides the diversity of behaviors (and cognition) seen in the anthropological examples, we know there is even much diversity in modern industrialized societies. Even comparing WEIRD societies, rates of various kinds of violence (homicides, suicides, police brutality, child abuse, etc) varies to a great degree. And we know that not all societies have an equal tradition of aggression at the political level, such that not all countries have a pattern of oppressing their own people and/or attacking other countries.

    Looking at countries around the world, what is the reason that some became aggressively militaristic and imperialistically expansionist while others didn’t? Some of the greatest empires were started by geographically small countries. What is in a culture or the larger conditions that causes or contributes to this happening? Or consider this. In the US, there isn’t higher rates of overall crime than many European countries. Where the US diverges is violent crime. Criminal acts, in the US, are more likely to end in victims being hurt/killed or in the criminals being hurt/killed by police. Why is that?

    • That is my side of the ‘debate’ that frustrated me to the point of giving up. It felt like I was being intentionally misinterpreted. Or else that he simply was incapable of understanding what I was actually saying. Either way, it felt pointless, a waste of time and effort. I don’t give up easily (after all, I’ve been talking to this guy for a couple of years), but eventually I do give up when communication failure becomes overwhelming.

      To his mind, I was supposed to play a role I didn’t want to play (anti-biological nurturist, utopian pacifist, and nostalgic primitivist) in a debate I didn’t want to have (nature vs nurture or whatever). In past discussions, I thought we came to an agreement that the nature-nurture debate made no sense. Yet here he was trying to force it back onto me again. This frame is a zombie idea that won’t die. It’s a memetic word virus that infects people’s minds and there is no known cure.
