Does it pay to be nice? Yes, it does. And we're not just talking about that warm fuzzy feeling inside, it pays in evolutionary terms of genetic success too. In fact being nice is unavoidable; humans, or any population of interacting individuals (including animals, insects, cells and even molecules) will inevitably cooperate with each other.

<p>It does pay to be nice if you repeatedly deal with the same person. Martin Nowak explains why cooperation also wins in matters of reputation, neighbourliness and family. But can evolutionary game theory save the world?</p>

<p><em>
As we saw in the <a href="http://plus.maths.org/content/does-it-pay-be-nice-maths-altruism-part-i">previous article</a>, we can use evolutionary game theory to show that it does pay to be nice when you repeatedly deal with the same person. Martin Nowak, from the <a href="http://www.ped.fas.harvard.edu/">Program for Evolutionary Dynamics</a> at Harvard University, explored many other types of games using this mathematics, and the evolution of cooperation seemed to be inevitable in all of them.</em></p><p><a href="http://plus.maths.org/content/does-it-pay-be-nice-maths-altruism-part-ii" target="_blank">read more</a></p>http://plus.maths.org/content/does-it-pay-be-nice-maths-altruism-part-ii#commentsmathematical realityaltruismcooperationevolutionary game theorygame theoryIterated Prisoners' DilemmaPrisoner's DilemmaMon, 23 Apr 2012 08:22:22 +0000Rachel5687 at http://plus.maths.org/contentMathematical mysteries: Survival of the nicest?

<h2>Survival of the nicest?</h2>
One of the most puzzling aspects of human behaviour is cooperation, in situations where backstabbing and selfishness would seem to be more rewarding. From the point of view of evolutionary theory, the very existence of altruism and cooperation appear mysterious. The mechanics of evolution seem to imply that rugged competition is the order of the day; that, given an opportunity to benefit by
cheating someone, or by defaulting on a deal, we will inevitably do so.<p><a href="http://plus.maths.org/content/mathematical-mysteries-survival-nicest" target="_blank">read more</a></p>http://plus.maths.org/content/mathematical-mysteries-survival-nicest#comments19altruismcooperationevolutiongame theoryIterated Prisoners' DilemmaMathematical mysteriesPrisoner's DilemmaTit for TatTit for Tat with forgivenessSat, 01 Dec 2001 00:00:00 +0000plusadmin4755 at http://plus.maths.org/content'SuperCooperators'

Sometimes it doesn't feel like the world is a very nice place. The news is filled with war, political conflict, crime – it seems we just can't get along.<p><a href="http://plus.maths.org/content/supercooperators-evolution-altruism-and-human-behaviour-or-why-we-need-each-other-succeed" target="_blank">read more</a></p>http://plus.maths.org/content/supercooperators-evolution-altruism-and-human-behaviour-or-why-we-need-each-other-succeed#commentsbook reviewcooperationMon, 23 Apr 2012 08:56:50 +0000Rachel5694 at http://plus.maths.org/contentGuilt counts

<p>Guilt, so some people have suggested, is what makes us nice. When we do someone a favour or choose not to exploit someone vulnerable, we do it because we fear the guilt we'd feel otherwise. A team of neuroscientists, psychologists and economists have this month produced some new results in this area, using a model from psychological game theory.</p>

<p>Guilt, so some people have suggested, is what makes us nice. When
we do someone a favour or choose not to exploit someone vulnerable, we
do it because we fear the guilt we'd feel otherwise. If this is the case,
then guilt is what holds together human society, as society is to a
surprising extent based on cooperation and trust. It would be interesting to
know what neural processes generate guilt, not just to answer fundamental
psychological questions, but also to understand disorders that are
associated with an excess or lack of guilt, such as anxiety and psychopathy.</p><p><a href="http://plus.maths.org/content/guilt" target="_blank">read more</a></p>http://plus.maths.org/content/guilt#commentsmathematical realityaltruismcooperationgame theorypsychologyTue, 17 May 2011 09:00:28 +0000mf3445486 at http://plus.maths.org/contentTrust me, I've evolved
