Reader Suzi pointed me to a RealClear Science article about subjects that cause controversy in psychology—but also in biology and among people in general.

The purpose of this study was severalfold, and I’m not going to go into all the questions and conclusions. What I found most interesting was the authors’ list of ten taboo conclusions about psychology and society, the degree of confidence that psychologists had in these conclusions, the degree to which psychologists would self-censor their opinions on these topics (and the correlation with their agreement between censorship and belief), and, finally, the consensus on academic freedom—the assent of psychologists that people should be able to study whatever they wanted.
First, the authors asked 41 psychologists to give a list of what they saw as “controversial” conclusions. From this they distilled the ten most controversial ones, often using their own phrasing to state the conclusions clearly.
Then, the authors gave these conclusions to a bigger sample of psychologists: 470 who agreed to answer the questions (4,603 were asked). Among other things, they were asked to state their degree of confidence in the answers and then their reluctance to share their views, whatever they were. They were also asked whether “scholars should be completely free to pursue research questions without fear of institutional punishment.”
I’ve put below the list of ten c0ntroversial conclusions derived from the preliminary survey, along with the average degree of agreement for each conclusion among the scholars who gave answers (not all 470 answered every question). First, how the scholars were asked to agree/disagree and how they judged their degree of risk that would make them self-censor (this is all from the paper itself):
Participants were told they would be responding to 10 taboo conclusions in the social sciences that were nominated by their peers in earlier interviews. First, participants responded to three questions regarding each conclusion on 101-point sliding scales (ranging from 0 to 100): “How confident are you in the truth or falsity of this statement?” (responses ranged from 100% confident it is false to 100% confident it is true), x
Participants then reported how at risk they would feel of various consequences if they shared their views on these topics openly on a sliding scale ranging from no risk at all to very high risk. (All sliding scales used in our study had a range of 0–100.)
After each question, I’ve put in bold the average degree of confidence among the respondents about whether they consider the conclusion to be true. Notice that the first question is about whether men were naturally selective to be sexually coercive, a conclusion I attacked strongly when younger (I’d have a more nuanced answer now, I think). Note that two of the questions, #4, #7, are taken up by Luana and me in our paper in Skeptical Inquirer, and we have high confidence in them (I just asked Luana, and we agreed that we both have 100% confidence in those two conclusions).
So here are the top ten hot potatoes in human psychology along with the average degree of agreement.
1. “The tendency to engage in sexually coercive behavior likely evolved because it conferred some evolutionary advantages on men who engaged in such behavior.” (53.47)
2. “Gender biases are not the most important drivers of the under-representation of women in STEM fields.” (45.26)
3. “Academia discriminates against Black people (e.g., in hiring, promotion, grants, invitations to participate in colloquia/symposia).” (59.29)
4. “Biological sex is binary for the vast majority of people.” (66.10)
5. “The social sciences (in the United States) discriminate against conservatives (e.g., in hiring, promotion, grants, invitations to participate in colloquia/symposia).”(52.06)
6. “Racial biases are not the most important drivers of higher crime rates among Black Americans relative to White Americans.” (46.93)
7. “Men and women have different psychological characteristics because of evolution.” (65.50)
8. “Genetic differences explain non-trivial (10% or more) variance in race differences in intelligence test scores.” (29.10)
9. “Transgender identity is sometimes the product of social influence.” (54.11)
10. “Demographic diversity (race, gender) in the workplace often leads to worse performance.” (21.44)
Note that for most topics psychologists had split opinions, but not for racial differences in IQ being somewhat based on genetic differences (question 8) or diversity leading to worse performance (question 10). In both cases a big majority of people disagreed The highest agreement, though, came for the questions that Luana and I discussed (sex being binary for the vast majority of people and men and women had different psychological traits because of evolution. It is surprising that questions whose answers are dead obvious, like the two I just mentioned, don’t have close to 100% agreement, which means that psychologists don’t know much about the binary nature of biological sex or about evolutionary psychology (note that question 7 doesn’t say that ALL psychological differences between men and women are evolved; it implies only that some of them are, which to me seems palpably true, e.g., differences in attentiveness to their offspring or the degree of choosiness in mating).
What I found almost as interesting to me is that there was, with one exception, a positive correlation between the degree of belief of individuals in these statements and their reluctance to share their views. Can you guess what the exception is?
Here are two graphs showing particularly strong correlations between degree of belief of a controversial statement and the degree of “self-censorship”; each point represents one individual. Surprisingly, the first one is the binary nature of biological sex. The more strongly you accept it, the more likely you are to keep it to yourself. That’s not true for Luana and me! It’s bloody obvious and we’ll shout it from the rooftops!
This one is more understandable as it’s the hottest of the hot potatoes: the claim that IQ differences between races are appreciable (at least 10% of the difference is based on genetic differences). The more you think that IQ differences between races are genetic, the more likely you are to keep it to yourself:
Did you guess that the one statement that people didn’t self-censor about was a statement in line with liberal ideology. Yes, it’s this one: “Academia discriminates against Black people (e.g., in hiring, promotion, grants, invitations to participate in colloquia/symposia).” The more confidence you have in that, that more likely you are to espouse it publicly, because it makes you seem less racist to be public about it.
All of the correlations, negative and positive, were statistically significant.
The authors note two differences in responses between males and females (that assumes a sex binary!), though of course these not be based on genetics or evolution (bolding is mine):
As seen in Table 3 and Figure S1 in the Supplemental Material, men believed more strongly in the truth of every single taboo conclusion relative to women, with two exceptions: (a) For political bias in social science, there was a small but not significant effect in the same direction, and (b) women believed more strongly that academia discriminates against Black people. In some cases, differences were quite large. For example, female psychologists (on average) were quite confident that academia discriminates against Black people, but male psychologists (on average) were on the fence; male psychologists (on average) were quite confident that men and women evolved different psychological characteristics, but female psychologists (on average) were on the fence. Future research should explore whether male and female psychology professors present to their students different evidence and arguments regarding the veracity of taboo conclusions.
As has been noted by some, women are likely to be more empathic than men, and this may explain the result vis-à-vis racial differences. Here’s another:
Female scholars were more left-leaning (M = 20.86, SD = 16.03) than male scholars (M = 27.90, SD = 18.70), t(401) = 3.93, p < .001, and younger, t(400) = 4.73, p < .001.
Since most academics are left leaning, I would expect this sex difference based on my hypothesis (which is not mine) that females are more empathic than men, and being more empathic makes you lean even more to the left (a hypothesis that is mine).
Finally, although self-censorship is rife in academia, I was glad to see that most scholars (but only by a bare majority) don’t think that people should be penalized for working on anything they want.
A slim majority of professors (52.3%) reported that scholars should be completely free to pursue research questions without fear of institutional punishment for their conclusions. By contrast,1.6% said scholars should not have this freedom, and 46.0% said it’s complicated.
Well, it is a bit complicated, for, as we said in our discussion in Amsterdam, there are some questions (though very few) that people should not be free to work on. But such work is banned anyway by research stipulations of granting agencies and academia, as this work involve harm to humans and other animals (i.e., the kind of experiments on inmates that Josef Mengele did in Auschwitz). Readers may want to think of some questions NOT involving harm to humans and other species that still should not be allowed. Right off the bat I can’t think of any. There are plenty of experiments that I think are not worthy of doing on humans, but none that should be banned if they don’t cause mental or physical harm.
The belief in academic freedom does conflict with the ability of researchers to investigate some of the questions above, particularly those that have implications for social policy (i.e. is there bias against blacks or women in academia?). It’s the “politically correct” thing to say that there is, but you really need to know how much bias there is versus other factors (culture, preference, etc) that can cause inequity before you start intervening to achieve equity. But I’ve discussed this before.
It would be a good thing if people didn’t have to self-censor, for that kind of censorship inhibits free discussion, the kind of discussion essential for a university to function and for people to examine their ideas and/or sharpen them. But we’ll never get rid of self-censorship on questions like the ones above so long as academia is pervaded by ideology, which it must be since scientists are humans and don’t want others to think poorly of them.
