Data from: Social setting, intuition and experience in laboratory experiments interact to shape cooperative decision-making

Recent studies suggest that cooperative decision-making in one-shot
interactions is a history-dependent dynamic process: promoting intuition
versus deliberation typically has a positive effect on cooperation
(dynamism) among people living in a cooperative setting and with no
previous experience in economic games on cooperation (history dependence).
Here, we report on a laboratory experiment exploring how these findings
transfer to a non-cooperative setting. We find two major results: (i)
promoting intuition versus deliberation has no effect on cooperative
behaviour among inexperienced subjects living in a non-cooperative
setting; (ii) experienced subjects cooperate more than inexperienced
subjects, but only under time pressure. These results suggest that
cooperation is a learning process, rather than an instinctive impulse or a
self-controlled choice, and that experience operates primarily via the
channel of intuition. Our findings shed further light on the cognitive
basis of human cooperative decision-making and provide further support for
the recently proposed social heuristics hypothesis.
