Skin switching, implicit racial bias and moral enhancement
A recent study has shown that a person’s implicit racial bias can be reduced if she spends some time experiencing her body as dark-skinned. Psychologists in Spain used an immersive virtual reality technique to allow participants to ‘see’ themselves with a different skin colour. They measured the participants’ implicit racial bias before and after the intervention, finding that the embodiment of light-skinned individuals in a dark-skinned virtual body at least temporarily reduced their implicit bias against people who are coded as ‘out-group’ on the basis of skin colour.
Implicit racial bias is an evolved, unconscious tendency to feel more positively towards members of one’s own race (one’s ‘in-group’) than towards members of a different race (members of an ‘out-group’). The bias can be (and was in this study) measured using a version of the implicit association test, which requires participants to quickly catagorise faces (black or white) and words (positive or negative) into groups. Implicit bias is calculated from the differences in speed and accuracy between categorising (white faces, positive words) and (black faces, negative words) compared to (black faces, positive words) and (white faces, negative words). Crucially, implicit racial bias has been shown to be uncorrelated with explicit racial bias – self-reports of negative racial stereotypes. This means that even those who are not consciously averse to people from other racial groups often demonstrate a deep-seated bias against them as an evolutionary hangover. Hearteningly, the authors of the study started from the idea that encoding people by race may be a reversible by-product of human evolution used to detect coalitional alliances. What their study confirmed is that immersive virtual reality provides a powerful tool for placing people into a different race ‘coalition’ by changing their body representation and consequently reducing their implicit aversion to the racial characteristics there represented.

Paracetamol Can Soften Our Moral Reactions
Our moral reactions are easily influenced by a variety of factors. One of them is anxiety. When people are confronted with disturbing experiences like mortality salience (i.e., being made aware of their own eventual death), they tend to affirm their moral beliefs. As a result, they feel inclined to punish moral transgression more harshly than they would without feeling fundamentally threatened. For example, in a now classical study people who objected to prostitution were asked to suggest a penalty for a woman arrested for prostitution. Participants who were led to reflect on their own mortality beforehand proposed a far higher bail than participants who thought about a less anxiety inducing topic. Such belief affirmation effects can also be evoked by psychologically disturbing experiences less severe than mortality salience. Hence, anxiety aroused by different situations can make our moral reactions more pronounced.
Treating ADHD may reduce criminality
Pharmaceutical treatment of attention deficit-hyperactivity disorder (ADHD) is associated with reduced criminality according to a study published yesterday in the New England Journal of Medicine. The study of over 25,000 Swedish adults with the disorder found that men undergoing pharmaceutical treatments had a 51% chance of committing at least one crime in a 4-year period compared to 63% for those not in treatment. The risk of criminality for women with ADHD was 25% for those taking medication, and 31% for those not in treatment. It’s possible, of course, that the reduction in criminality associated with treatment was due not to the treatment itself, but to other factors, such as desire to improve behaviour, which could have both motivated treatment and reduced criminality. However, even when the investigators adjusted for likely confounders, they found that treatment was associated with significantly reduced criminal offending. Thus, their findings are at least suggestive of a causal relationship between medication and reduced crime.
It will be interesting to see how such a relationship, if it can be further supported, will be viewed by the general public and medical profession. Will it be seen as strengthening or weakening the case for ADHD treatment?
On being yourself
‘I was always the life and soul of the party, flirting with everyone’, wrote Lucille Howe, in ‘Fabulous Magazine’, (22 July 2012), ‘but I wanted John to fall in love with the real, quieter me’. In the same article, Charlotte Ruhle notes how her psychotherapy helped her to recover from a broken relationship. ‘[My] friends started saying I….seemed more like my old self.‘
The media, and indeed our ordinary conversations, are awash with this sort of language. Not only are we conscious – having a sense that there is an ‘I’ that is in some sort of continuity with the ‘I’ that existed yesterday, will hopefully exist tomorrow, and to whom things happen – but we have firm convictions about the nature of the ‘I’. When it is not allowed to express itself – to ‘be itself’, we complain. Depending on our education, we say that we’re ‘out of sorts’, ‘not myself’, or ‘ontologically vertiginous’. Continue reading
Psychiatric drugs to enhance conformity to religious norms, and conscientious objection
An article in the Israeli newspaper Haaretz reports on the (alleged) frequent use of psychiatric drugs within the Haredi community, at the request of the religious leaders, in order to help members conform with religious norms. Haredi Judaism is the most conservative form of Orthodox Judaism. It is sometimes referred to by outsiders as ultra-Orthodox. Haredim typically live in communities that have limited contact with the outside world. Their lives revolve around Torah study, prayer and family.
In December 2011, the Israel Psychiatric Association held a symposium entitled “The Haredi Community as a Consumer of Mental-Health Services”. One of the speakers was Professor Omer Bonne, director of the psychiatry department at Hadassah University Hospital. Professor Bonne is claimed to have said that sometimes yeshiva students (yeshiva is a religious school) and married men should be given antidepressants even if they do not suffer from depression, because these drugs also suppress sex drive.
Sam Harris is wrong about science and morality
By Brian Earp (Follow Brian on Twitter by clicking here.)
WATCH MY EXCHANGE WITH SAM HARRIS AT OXFORD – ON YOUTUBE HERE.
I just finished a booklet by “New Atheist” Sam Harris — on lying — and I plan to write about it in the coming days. But I want to dig up an older Harris book, The Moral Landscape. Why? Because it still makes me grimace.
I say “still” because I read the book months ago. I just haven’t yet vented my bafflement. Permit me to gripe, then, about Harris’ (aging) “bold new” claim — presented in his book — that science can “determine human values” or “tell us what’s objectively true about morality” or “give us answers about right and wrong” or however else you package this fiction.
In his new book (the one about lying) Harris says, in effect, you should never, ever, do it — yet his pretense in The Moral Landscape to be revolutionizing moral philosophy seems to me the very height of dishonesty. What he actually does in his book is plain old secular moral reasoning — and not very well — but he claims he’s using science to decide right from wrong. That Harris could be naive enough to think he’s really bridged the famous “is/ought” chasm seems incredible, and so I submit that he’s exaggerating* to sell books. Shame on him.
*A previous version of this post had the word “lying” here, but I was told that my rhetorical flourish might be interpreted as libel. I hope “exaggerating” is sufficiently safe. Now onward to my argument:
