There is so much to poke fun at in this article.
After carrying out this kind of social experiment, the researchers developed a computer algorithm which set out to classify people according to their behavior. The computer algorith organized 90% of people into four groups: the largest group, accounting for 30%, being the Envious -- those who don't actually mind what they achieve, as long as they're better than everyone else.
So they got the data, then tried to design their classification algorithm. Which might be innocent, but waves a pretty red flag that says there might be nothing here, but I'll find something anyway, if I look hard enough.
But coming from a different direction, some game theorists set up some game-like scenarios, with rotating partners/competitors, and then when 30% judge their own ability in comparison to participants around them, the researchers announce envious is now a personality type.
