The beta-blocking medication propanol could also block subconscious racist attitudes.
Although racism is widely believed to be a learned behavior, findings
from an Oxford University team suggest that taking a heart disease
medication may also help mute subconscious racist attitudes in
individuals. Researchers gave the drug propranolol to 18 subjects, and
placebos to a control group of the same size. Those that received the
drug scored markedly lower on a standard test that measures subconscious
racial bias. Does this mean we could one day see a pill to counter
racist tendencies?
