People who want a fatter paycheck will find that being shy, reserved or brooding at work won't help. In fact they'll probably find that their more outgoing, talkative and self-starting colleagues will beat them to it.
The results of a new study by researchers at the University of Jyväskylä have confirmed our worst fears - extroversion, the love of being in the public eye, is the only personality trait that positively affects income-earning capacity. Apparently, serious qualities such as conscientiousness won't boost earning power.
Perhaps for obvious reasons, outgoing people have also been found to be better at networking that their less talkative colleagues.
The University of Jyväskylä researchers measured extroversion on a scale of one to five. They found that employees who were just one step ahead of their colleagues on the chattiness scale earned up to 15 percent more than their quieter workmates.
Personality is also a factor that recruiters take into consideration when hiring the right employee, particularly for leadership positions. As far as these professionals are concerned, top brass positions are not for the faint of heart - or voice.
The study followed a group born in 1959 from childhood into adulthood. It seems to suggest something many have long suspected: knowledge and ability just aren't enough to get ahead in this world. To really pull in the big bucks, people have to be sociable, active, even effervescent - or at least seen to be so.
