Can neuroeconomics help economics become a real science?

Posted 06 Oct 2012 / 0

The Chronicle of Higher Education “The Marketplace in Your Brain” I think that this article suggests that much of economics is not much of a science. Faced with new information, mainstream economics has failed to update its models of how the world works. Doing so would make economics akin to physics or medicine or evolutionary Read More

Enforcing norms may be for personal gain, not to maintain social order (at least amongst Santa Barbara undergraduates)

PLoS ONE “What Are Punishment and Reputation for?” Once again, a valuable and ingenious experiment over-reaches on the meaning of its finding, and the over-reach bleeds into the popular media.

Punishment, properly rewarded, can promote cooperation without corruption

Public Library of Science ONE “Evolving Righteousness in a Corrupt World” In the race to build the next over-simplified model of cooperative dynamics, it will be interesting to see how the media runs with this one. Is this a “scientists discover the evolutionary rationale for honorable police” moment? I think it is important to take Read More
