Robert Axelrod conducted a computer tournament between two computers based on the prisoner’s dilemma to investigate reciprocal altruism and cooperation in a social setting. More specifically to examine the evolution of cooperation. Cooperation and reciprocal altruism are two concepts that (to some degree) go hand in hand and for this reason they are considered the most studied topics in evolutionary psychology. Axelrod, like his predecessors, wanted to further understand why humans cooperate with individuals they are not related to. The prisoner’s dilemma is a game that exhibits co-operation and defection when two strangers are pitted against one another for points. …show more content…

‘Tit-for-Tat’ displays the perfect example of altruism as well as reciprocal altruism within human society. Basically if one individual does a favor for another individual, the other individual is more likely to return the favor (co-operation). However, if an individual does a favor for one person and that person commits some form of subtle cheating or does not repay the favor; the first individual might not do another favor for that person (defection). Nonetheless being ‘nice’ might not always benefit in society because there are always social factors that display selfishness thus trying to cheat the altruistic individual. Therefore, ‘tit-for-tat’s’ strategy for copying the opponent goes a long way. Furthermore, this strategy sheds light on how altruism might actually benefit from functioning in a similar manner thus preventing biases and forms of subtle cheating by members of society. It also assists in understanding the basis of cooperation and why we might decide to help out individuals we are not related …show more content…

Natural selection or genetic evolution requires reproduction to occur for the genes to successfully pass from one generation to the next. Memes, however, do not require reproduction they simply have to appeal to the beholder’s mind to be passed on. A second difference between the two types of evolution is also linked to their method of replication (to some degree). The genes need to have some sort of benefit to the holder for them to be selected for. However, memes in general do not need to hold some form of benefit to the holder, they can be both beneficial and/or detrimental. As mentioned, memes simply need to appeal to the mind of the beholder and cause a behavior to occur. Along the same lines it is important to note that whereas genes hold a benefit for the individual; they also take environmental changes into account as well thus setting the stage for natural selection. Another difference between genes and memes is that genes only exist in one form which is within the genome whereas there are two forms in which a meme exists. The first is that a meme exists in the form of a mental representation and the second form is the elicitation of a behavior. Genes do not elicit behavior whereas memes cause behavior and even when they do it is not a source of replication. The elicitation of behavior is what causes a meme to be represented thus leading a meme to be replicated
