Evolutionary scientists details why 'existential angst' makes progressives less happy than conservatives

Conservatives are happier than liberals, and evolutionary behavioral scientist Dr. Gad Saad says there's a simple reason why.

Appearing on Fox News' "Hang Out with Sean Hannity" podcast, Saad pointed to decades of "unequivocal" research showing conservatives consistently report higher levels of happiness than their counterparts on the left, arguing the difference stems from how each side views society.

"I offer a speculative explanation, but I think it makes sense," he said in Tuesday's episode.
