Washington Post science journalist Vedantam theorizes that there's a hidden world in our heads filled with unconscious biases, often small, hidden errors in thinking that manipulate our attitudes and actions without our knowing it. Autonomy is a myth, he says, because knowledge and rational intention are not responsible for our choices. This thesis is not news— since Freud, psychologists have taken the unconscious into account—but Vedanta argues that if we are influenced sometimes, then why not all the time, whether we're launching a romance or a genocide. This is a frightening leap in logic. In anecdotal, journalistic prose, we learn that, through bias, rape victims can misidentify their attacker; people are more honest even with just a subtle indication that they are being watched; polite behavior has to do with the frontotemporal lobes rather than with how one was raised; and that we can be unconsciously racist and sexist. Though drawing on the latest psychological research, Vedantam's conclusions are either trite or unconvincing. (Jan. 19)
