>Cool people are largely perceived to be extroverted, hedonistic, powerful, adventurous, open and autonomous.
(I disagree with their lists at the end of their article tho ;)
I would say that adventurous, open and autonomous are three qualities that make a person interesting, as opposed to boring. They likely have entertaining stories and an approach to life that repels dullness.
And extroversion, though it doesn't have much bearing on being interesting, makes it a little more likely that I'd encounter them and get to know the three other qualities.
Just an observation, nothing else.
I’m sure lol…
