“When Donald Trump tweeted that he was a ‘very stable genius,’ he was accused of lacking self-awareness by journalists and comedians. But the truth is that no one has perfect self-awareness—you probably believe more than a few things about yourself that are false. Whether it’s in trying to land a job or impress a date, people spend a staggering amount of time making claims about themselves. It makes sense: You’re the only person on Earth who has direct knowledge of every thought, feeling, and experience you’ve ever had. Who could possibly know you better than you? But your backstage access to your own mind sometimes makes you the last person on Earth others should trust about it. Think of it like owning a car: Just because you’ve driven it for years doesn’t mean you can pinpoint when and why the engine broke down. Sixteen rigorous studies of thousands of people at work have shown that people’s coworkers are better than they are at recognizing how their personality will affect their job performance. As a social scientist, if I want to get a read on your personality, I could ask you to fill out a survey on how stable, dependable, friendly, outgoing, and curious you are. But I would be much better off asking your coworkers to rate you on those same traits: They’re often more than twice as accurate. They can see things that you can’t or won’t—and these studies reveal that whatever you know about yourself that your coworkers don’t is basically irrelevant to your job performance.” Read the rest of the article at The Atlantic.
