 The emphasis is shifting from pure laboratory research towards research testing combinations of motivational, strategic, and structural solutions.It is encouraging that researchers from various behavioral sciences are developing unifying theoretical frameworks to study social dilemmas (like evolutionary theory; or the Social-Ecological Systems framework developed by Elinor Ostrom and her colleagues).For instance, there is a burgeoning neuroeconomics literature studying brain correlates of decision-making in social dilemmas with neuroscience methods.
