New York HAPPY PURIM TO ALL
- A common heart disease drug may have the unusual side effect of combating racism, a new study suggests.

Volunteers given the beta-blocker, used to treat chest pains and lower heart rates, scored lower on a standard psychological test of “implicit” racist attitudes. They appeared to be less racially prejudiced at a subconscious level than another group treated with a “dummy” placebo pill.
Scientists believe the discovery can be explained by the fact that racism is fundamentally founded on fear.
Propranolol acts both on nerve circuits that govern automatic functions such as heart rate and the part of the brain involved in fear and emotional responses. The drug is also used to treat anxiety and panic.
Experimental psychologist Dr Sylvia Terbeck, from Oxford University, who led the study published in the journal Psychopharmacology, said: “Our results offer new evidence about the processes in the brain that shape implicit racial bias.
“Implicit racial bias can occur even in people with a sincere belief in equality. Given the key role that such implicit attitudes appear to play in discrimination against other ethnic groups, and the widespread use of propranolol for medical purposes, our findings are also of considerable ethical interest.”

The test involved categorising positive and negative words, and pictures of black and white individuals, on a computer screen. More than a third of the volunteers had a “negative” IAT score, meaning they were biased towards being non-racist at a subconscious level. This was not seen in any member of the placebo group.
Co-author Professor Julian Savulescu, from Oxford University’s Faculty of Philosophy, said: “Such research raises the tantalising possibility that our unconscious racial attitudes could be modulated using drugs, a possibility that requires careful ethical analysis.
“Biological research aiming to make people morally better has a dark history. And propranolol is not a pill to cure racism. But given that many people are already using drugs like propranolol which have ‘moral’ side effects, we at least need to better understand what these effects are.”
