    That the success of humans as a species depends to a large extent on our ability to cooperate in groups is widely believed. Much more so than any other animal, people are able to coordinate and join their forces and actions to produce mutual benefits.

New research involving Dr Molleman, an expert at the University of Nottingham, suggests that successful cooperation in groups depends on how people gather information about their peers, and how they base their cooperative decisions on it.

Biologists wonder how cooperation could have developed by natural selection: it is puzzling how cooperation can be beneficial when it is possible to behave selfishly and take advantage of the cooperative efforts of your group. Psychologists and economists try hard to understand why many people are willing to sacrifice their own welfare to benefit their social environment. They asked questions like “How do people make decisions when their actions can affect the welfare of others?” “How people determine their behavior when they have to cooperate in groups?”.

Dr Pieter Van Den Berg from the University of Groningen said, “From previous research we know that some people are ‘majority-oriented (以……为中心)’ and tend to look at the behavior of the majority in their group, whereas others are ‘success-oriented’ and try to find out what kind of behavior pays off best for themselves.”

Dr Molleman, from the center of the Decision Research and Experimental Economics, said, “It turns out that behavior in groups of success-oriented people was much more selfish than it in groups of majority-oriented people. As a consequence, the people in the majority-oriented groups tended to cam more money in the experiment since they cooperated more.”
