So how many psychopaths are in your life? Writing for the Telegraph, Tom Chivers says, “We think of psychopaths as killers, alien, outside society. But, says the scientist who has spent his life studying them, you could have one for a colleague, a friend – or a spouse”:
There are a few things we take for granted in social interactions with people. We presume that we see the world in roughly the same way, that we all know certain basic facts, that words mean the same things to you as they do to me. And we assume that we have pretty similar ideas of right and wrong.
But for a small – but not that small – subset of the population, things are very different. These people lack remorse and empathy and feel emotion only shallowly. In extreme cases, they might not care whether you live or die. These people are called psychopaths.
