Extroversion and effective Selling , this explodes the myth

Adopted from the following great saying of Daniel Pink explodes the myth around extroverts being good sales people..

“We have this idea that extroverts are better salespeople. As a result, extroverts are more likely to enter sales; extroverts are more likely to get promoted in sales jobs. But if you look at the correlation between extroversion and actual sales performance – that is, how many times the cash register actually rings – the correlation’s almost zero.”
