Researchers at Oxford University have found that a popular blood pressure pill, Propranolol, has the added the benefit of abolishing implicit "subconscious" racial bias in patients:
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.

Propranolol reduces implicit negative racial bias.
An encyclopaedia could be written on the ethical implications of this. I can just see a defendant in a hate crime trial, "I forgot to take my Propranolol!" Could the management of a corporation found guilty of systematic discrimination be required to undergo a course of treatment? The possibilities boggle the mind . . .
