A study has found that 1 in 25 business is a psychopath:

One out of every 25 business leaders could be psychopathic, a study claims.

The study, conducted by the New York psychologist Paul Babiak, suggests that they disguise the condition by hiding behind their high status, playing up their charm and by manipulating others.

Favourable environmental factors such as a happy childhood mean they can function in a workplace rather than channelling their energies in more violent or destructive ways. Revealing the results in a BBC Horizon documentary, Babiak said: “Psychopaths really aren’t the kind of person you think they are.

“In fact, you could be living with or married to one for 20 years or more and not know that person is a psychopath.

“We have identified individuals that might be labelled ‘the successful psychopath’.

“Part of the problem is that the very things we’re looking for in our leaders, the psychopath can easily mimic.

On Wall Street, I would expect the number to be closer to 24 out of 25.
