Pill for heart disease may reduce racial bias

world Updated: Mar 10, 2012 23:29 IST

A drug used to treat heart disease can affect a person’s subconscious attitudes towards race, a new study has claimed.

In the study at the Oxford University published in Psychopharmacology, researchers gave 18 people drug propranolol and 18 people a placebo and found that the propranolol group scored significantly lower on the Implicit Attitude Test into subconscious racial bias — a standard test for testing subconscious racial attitudes.

There was no significant difference in the groups’ explicit attitudes to other races, a university release said.

Propranolol is a beta-blocker used to treat heart disease that blocks activation in the peripheral autonomic nervous system and in the area of the brain implicated in fear or emotional responses.

Researchers believe propranolol reduced implicit racial bias because such bias is based on automatic non-conscious fear responses, which propranolol blocks.

Sylvia Terbeck lead author and experimental psychologist at Oxford University 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,” she said.

“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,” Terbeck said. She pointed out that many people with medical conditions are probably already on drugs which affect subconscious bias, and more research is needed into how drugs which affect our nervous system affect our moral attitudes and practices.
