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="https://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="https://plus.maths.org/content/does-it-pay-be-nice-maths-altruism-part-ii" target="_blank">read more</a></p>https://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 https://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="https://plus.maths.org/content/mathematical-mysteries-survival-nicest" target="_blank">read more</a></p>https://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 https://plus.maths.org/content
