Writing in the medical journal Psychopharmacology, British investigators found that a veteran heart and blood pressure pill, propranolol, which acts to lower our fight-or-flight response to anything by dialing down adrenaline production, reduced “implicit racial bias” significantly. They ran their study in 36 white 22-year-old volunteers and distinguished implicit associations from explicit racial prejudice. The implicit kind—seeing something that makes you uncomfortable and reacting with a quickened pulse—was the type “improved” while good, old-fashioned explicit racial prejudice was unchanged. In other words, the drug didn’t make you more tolerant, just less physiologically perturbed about the whole thing.
