More human cooperation if based on intuition ?

" Finally, an induction that primes subjects to trust their intuitions increases contributions compared with an induction that promotes greater reflection. To explain these results, we propose that cooperation is intuitive because cooperative heuristics are developed in daily life where cooperation is typically advantageous. We then validate predictions generated by this proposed mechanism. Our results provide convergent evidence that intuition supports cooperation in social dilemmas, and that reflection can undermine these cooperative impulses."

Editor's summary

Generosity is a question of timing

Many people are willing to make sacrifices for the common good, but little is known about the cognitive mechanisms that underlie such cooperative behaviour. In economic experiments subjects often contribute cooperatively against what rational self-interest should dictate. This study uses a series of ten varied experimental designs, including both one-shot and repeated games, to establish whether we are intuitively predisposed to cooperate or to act selfishly. And it seems our gut response is to cooperate — but given more time to think the logic of self-interest undermines collective action and we become less generous.
