How do religions form?

People are very superstitious in nature and are very bad at establishing cause and effect. In this episode here, Derren Brown recreates Skinner's pigeon experiment using people to show that people form a false conclusion between cause and effect. If you look at basic tribal religions you will find superstitious practices. One time they did a dance, they had a great catch, other times, they associate a bad harvest to the actions of an individual. They continue to perform the actions that give good results and ban the actions that they associate with poor results. After all, religion is mostly organized superstition.
