Are We Wired To Be Selfish or Altruistic?<br>Under the survival-of-the-fittest mentality, man evolved to compete for precious resources, making us a relatively selfish bunch (yielding a potential mate to a rival, for example, doesn't do your genes any good in seeing another generation). But those theories fail to account for the fact that humans could not have survived without the occasional charity and social reciprocity of the group, too. And studies show that this altruism is innate. Even 18-month-old toddlers will almost always try to help an adult who is visibly struggling with a task, without being asked to do so: if the adult is reaching for something, the toddler will try to hand it to him. Another study found that 3-to 5-year olds tend to give a greater share of a reward (stickers, in this case) to a partner who has done more work on a task — again, without being asked — even if it means they get to keep less for themselves. How is all this helping hard-wired? Our stress systems themselves seem to be designed to connect us to others. They calm down when we are feeling close to people we care about — whether related to us or not — and spike during isolation and loneliness. Even short periods of solitary confinement can m'derange the mind and damage the body because of the stress they create. Of course, that doesn't mean humans are never selfish, but those bouts of self-centeredness seem to be balanced with a good dose of the Good Samaritan as well.
