Darker origin behind the kindly act of fairness

We often think of playing fair as an altru�istic behavior. We're sac�ri�ficing our own poten�tial gain to give others what they deserve. What could be more self�less than that? But new research from North�eastern Uni�ver�sity assis�tant pro�fessor of phi�los�ophy Rory Smead sug�gests another, darker origin behind the kindly act of fairness.Smead studies spite. It's a conun�drum that evo�lu�tionary biol�o�gists and behav�ioral philoso�phers have been mulling over for decades, and it's still rel�a�tively unclear why the seem�ingly point�less behavior sticks around.
