Scientific Fraud and Disciplinism

Published 14 September, 2011

Just about one year ago, the Wall Street Journal published a piece by Eric Felten about the scandal in which Marc Hauser was embroiled. Felton followed the usual rules of the anti-evolutionary psychology game – alluding to how the discipline seemed to “justify” rape and remarking that “speculative tales” were the hallmark of the field – in the service of arguing that because Hauser was guilty of misconduct, this somehow “spells trouble” for the entire field of evolutionary psychology.

Recently, new scientific scandals have blossomed. The Economist this past week led their Science section of the magazine with a story about two cancer researchers at Duke – Potti and Nevins – whose work seems to have come under something of a shadow. A number of errors have been discovered in their published work, and other researchers have, according to The Economist, been unable to replicate their results, and one of the researchers, Nevins, is quoted as claiming that “some of the data in the papers had been ‘corrupted,’” a word that caught my attention for some reason. Several papers have been retracted, but, I hastily add, as far as I can tell, no one seems to think that this “spells trouble” for the entire field of oncology.

Back in the field of psychology, last week Science published a story about social psychologist Diederik Stapel, who has been fired from his position at Tilburg University after admitting that he faked his data. The press release from Tilburg uses the plural, publicationS:

The Executive Board of Tilburg University has suspended Prof. D.A. Stapel from his duties with immediate effect. Dr Stapel, who is a Professor of Cognitive Social Psychology and Dean of the Tilburg School of Social and Behavioral Sciences, has committed a serious breach of scientific integrity by using fictitious data in his publications.

There is an ongoing investigation, so it’s not clear which publications are affected. People who follow evolutionary psychology might be interested in the status of the recent Psychological Science paper, which claimed to speak to the ongoing debates surrounding infidelity:

Researchers have found that men are more likely to be unfaithful than women are. Such findings are typically explained with  evolutionary theories, which hold that men and women use  different strategies for spreading their genes and having offspring…In contrast, other researchers have proposed that this gender difference is (at least partially) a reflection of structural  differences in the socioeconomic position of men and women.

The Psych Science paper reported that sex did not moderate the relationship between power and infidelity. I might note that Stapel is not the corresponding author on that paper, and I have no particular reason to suspect the data from 1,561 subjects were just made up.

Unlike Eric Felton, as far as I know, commentators on these scandals do not seem to think that what these individuals did reflects in some way on the entire discipline in which they work. I’ll be surprised if the Stapel matter leads anyone to say, out loud, for instance, that somehow his actions should lead us to believe that social psychology is a hopeless wasteland of pseudoscience, replete with superficial or vacuous theory and parlor tricks that pass for scientific experiments.

Anyway, I suppose my point is the slightly obvious one that the way that people perceive misdeeds depends on the groups to which the wrongdoer belongs. Which brings me to the television program What Would You Do?, which should be watched by anyone interested in how people respond to other people’s moral violations.

Some communities would have you believe that humans are avid third party punishers, imposing costs on those who violate a rule, even if they themselves are unaffected. WWYD stages such violations, and records the results. On Hulu, you can see what happens when an actor is placed in a park, stealing a bicycle.

At 2:13, they give the statistics, with over a hundred people passing by; just one couple intervenes. Now, that’s with a young, White actor. At 3:06, they replace the White actor with a Black one… and at 3:08 someone’s ready to call the cops. Even better is the tableau at 6:41, when they run the same scenario, but with a young woman. Do people intervene in this case? Sort of… At 7:18, a nice older man asks our young thief if she could use some help…

The point is that, perhaps not surprisingly, people use others’ moral failings differently depending on who the culprit is. If the offender belongs to a group that, for whatever reason, you’d like to punish anyway, well… in the bicycle case, it seems to me that you might call this racism, discriminating against someone on the basis of their race. When you do this because of someone’s field, that’s disciplinism.

As a little bit of an aside, some of the buzz about these scandals seems to lead people to ask… why? Why would someone fake their data just to get published in the most prestigious journals on the planet? This reminds me of one of the old Deep Thoughts by Jack Handy from Saturday Night Live:

What is it that makes a complete stranger dive into an icy river to save a solid-gold baby?  Maybe we’ll never know.

  • Jesse Marczyk

    The video is certainly interesting, but whoever is giving the explanations (the Yale professor) as to the “whys” of men are deciding to help an attractive woman, how come the suggestion of sexual motivation doesn’t come up?

    Nope; it couldn’t be sexually motivated, it’s because “attractiveness” is associated with “goodness”, and “non-threatening”

    • Ian

      I actually disagree that the motivation is sexual. I’m speaking purely in generalizations here, but in my experience men who are most likely to be able to copulate with a highly attractive woman are probably less likely to help her, whereas men who are less likely to be able to copulate with her are more likely to supplicate themselves by providing assistance.

      Of course, some of this supplication may take the form of men hoping for a sexual exchange, but the features of this are too complicated to be predicted by a simple sex-seeking model.

      • Jesse Marczyk

        Whether or not they actually stand a chance of copulating and the means by which they seek that goal are beside the point as to the motivations – conscious or unconscious as they might be – that generate the behavior.

      • Ian

        Yes and no. It’s hard to believe that male instincts would be wholly linear and not to take into account the probability of successfully copulating with the woman in question. Therefore a model that produces rigorous predictions about the ways in which a man would assist a woman in such a situation would have to be more fine-grained than just sexual motivation = help woman.

        Linear social cognition modules would be easily manipulated and not very useful in competitive situations. As such I would expect to see explanations far more complicated than simple dichotomy between sex-seeking and social assistance. And whether people are consciously aware of the output of such a module, or experience a press-secretary-style untruth regarding their social behaviour is really besides the point if you want to predict behaviour.

        • Jesse Marczyk

          I would imagine that the estimated probability of success is taken into account, though the threshold is probably a fairly low one for men, contingent on the costs of extending that helping behavior.

          Were sexual motivations not really a factor, I would predict at least two things: (1) that men should be just as likely to extend assistant towards the other men, and not just towards the woman in this case, and (2) that men and women should have been equally likely to assist in any of the cases; that’s just not what we saw.

        • Ian

          Look, I don’t disagree with you in principle Jesse. My problem is that even with that elaboration, it’s still far too simplistic to just say “sexual motivations” and be really saying anything useful.

          We can all agree that social cognition is massively based on emotion, therefore it is instinctively processed. I always like to say that you can’t anthropomorphize instincts. To say that they’re “sexually motivated” gives people a mental model that someone is consciously calculating what is most likely to get them sex.

          However it is easy to see that this is probably not true. An instinctive module is far more likely to not be particularly outcome-oriented (hard to calculate outcomes) and more likely process-oriented, with the processes modulated by evolutionary pressures.

          Therefore men in this situation are acting in ways that on average maximized reproductive fitness in the EEA. Whether a particular course of action maximized fitness due to short-term mating opportunities, long term opportunities or increased social status, or something completely is very difficult to say. But they do not act a certain way because they are sexually motivated at that time, or at least, thinking that way is a produces a very coarse mental model.

          And sorry if I’m a bit of a dick about this. I know you probably have a lot more qualifications than me. However, despite evo psych’s world-beating model of human behaviour, it still continues to be marginalized as a scientific discipline, showing that there are still many more refinements to be made.

          Until you can use your own model to manipulate people into believing that model you’re not there yet. And indeed, as an outsider, most of the people in evo psych seem to be largely blind, press secretary style, to their own blindspots. I’m sure I look the same to you.

          • Jesse Marczyk

            Yes, I am speaking in very broad terms. To clarify again, the sexual motivation (i.e. the outputs of a mating module) need not be conscious; parts of it might be at times, but the processing is happening at a different level. In other words, they don’t actually need to have an erection when they’re helping a woman for the motivations of that helping to be partially (largely?) the result of the outputs of mating modules.

            My point is that Jack Dovidio’s response as to why some men – and only men – were helping the woman – and only the woman – doesn’t explain the pattern of behavior.

          • Ian

            Yeah, fair call. I do apologize, because to an extent I’ve hijacked your comment for a further elaboration of my own.

            My point then is that although the overall motivation is sexual, a straightforward calculation of the likelihood of mating is likely modulated by modules that look for an individual’s relative social status, resource security, local rate of violence and more. Except that none of these patterns really exist in modern societies in the same way, thus the outputs of such hypothetical modules will look largely like random noise (or variations in personality).

            In a way you could say that the standard model is that this is sex-seeking behaviour modulated by personality. But that would be a crude approximation. It’s not personality, it’s just integration of further information, processed by obsolete pattern-recognition systems.

    • Robert Kurzban

      Just for completeness, the professor in question is Jack Dovidio.

    Hello Rob,
    “Anyway, I suppose my point is the slightly obvious one that the way that people perceive misdeeds depends on the groups to which the wrongdoer belongs. ”
    Stapel did a study about that…

    • Robert Kurzban

      Huh. Delightful. Thanks for pointing that out.

      • Hugo Alves

        U’re welcome!

    I think, the way the men and women treated the attractive woman is a prime example of inter and intra sexual competition.

    It’s ironic that Hauser is considered representative of evolutionary psychology; he declared his exit from the field several years ago:

    “[I]n recent years, I have made less use of Darwin’s adaptive logic. . . . [W]ith respect to questions of human and animal mind, and especially some of the unique products of the human mind — language, morality, music, mathematics — I have, well, changed my mind about the power of Darwinian reasoning. . . . I have lost the faith, so to speak, … in the power of the adaptive program to explain or predict particular design features of human thought. . . . In fact, I would say that although Darwin’s theory has been around, and readily available for the taking for 150 years, it has not advanced the fields of linguistics, ethics, or mathematics. . . . Bidding Darwin adieu is not easy. My old friend has served me well. And perhaps one day he will again. Until then, farewell.”
