List of Behaviors Not Explained by Self-Interest

Started this list upon reading Book: A Cooperative Species (Bowles & Gintis, 2011). On p.10, they start by giving some examples of behavior that is not explained by self-interest.
I thought it would be interesting to start keeping a list to refer back to. This could aid in the attempt to find other governing mechanisms that could explain some subsets of this list. In other words, to identify categories of explanations/motivations that explain why people do things.
== List ==
* Voting: why would people bother to vote? It is likely costly for most people, and a single vote has basically zero effect on any outcomes. 
* Terrorist violence: unlikely to change anything for the better, and highly costly/deadly for those who participate. Evidence shows it is motivated as a reaction against perceived injustice. 
== Categories of Alternative Explanations/Governing Mechanisms ==
* Morals
* Norms
* Prosocial preferences/caring about others directly
* Rules of thumb
* Cravings
* Lack of self-control
* Inertia
* Intuitive dislike
*
