An analysis of data from mergers of financial-advisory firms revealed that “an adviser is 37 percent more likely to commit misconduct if he is merged into a new branch that includes individuals with a history of misconduct (relative to an adviser from the same firm who is merged into a branch with no history of misconduct). This implies a social multiplier of 1.59, meaning that a case of misconduct by an advisor results in an additional 0.59 cases of misconduct by that adviser’s co-workers.” This wasn’t explained by changes in supervisors, and there was no evidence that good conduct was similarly contagious.

Prejudice by the numbers

In experiments, psychologists from Rutgers asked students (mostly white and Asian, but not black) about their impressions of the intelligence of people who were white or black. Impressions of the “average” white vs. black person were prejudiced against blacks. This was true both for deliberate responses and automatic associations. However, when judging specific individuals in college applications, prejudice was “effectively eliminated” with objective information (i.e., SAT, GPA). In other words, individuals with similar qualifications were judged similarly, regardless of race.

Synonyms aren’t the same

In experiments, psychologists at the University of Southern California found that ostensibly synonymous words can have significantly different positive or negative connotations. For example, Daniel was perceived more negatively with “utterly” than “totally” in this sentence: “As his siblings discovered, Daniel was a[n] utterly [totally] changed man when he returned.” Likewise, Steve was perceived more negatively with “caused” than “produced” in this sentence: “In his past term, Governor Steve Williams introduced regulations that caused [produced] extreme changes to the budget.”

From broken homes to current events


In experiments, people read through a news slideshow. If it depicted a deteriorating, unpredictable economy, participants who had grown up in dysfunctional homes did better on tests of the ability to update short-term memory, while the reverse was true for participants who had grown up in good homes. For other aspects of short-term memory that the researchers theorize weren’t as adaptive in dysfunctional homes, performance worsened for participants from such homes in the dysfunctional-economy condition, while performance improved for participants from good homes.

Genuinely narcissistic

In an experiment, individual young children were left alone in a room after being asked not to peek at a toy in the room but out of view. When the adult returned, a mirror was placed in front of some of the children; the unreflective back of the mirror was placed in front of some of the other children; and the rest of the children were simply asked to promise to tell the truth. Children in front of the mirror were significantly more likely to tell the truth when asked if they had peeked. There was no difference in lying between children who looked at the back of the mirror and those who promised to tell the truth.
