In vsauses video "The Future of Reason" he talks about how logic is a best seen in a group context, (a group consensus). So if a group of people agree on something, that is how it is. You can also put in some "if its not important to change the consensus for the group, don't change it" as to why belief in groups doesn't change very fast. Also the social and economic aspect, groups have people, people need people, you can also more easily find skilled people in a group.
(both religious and secular groups). Examples of belief, god cannot be observed directly, but religious people still believe : scientists can't find dark matter, but they still believe that it exists. The most important reason is that groups in general serve the people that are in them. Religions keep together well because the majority of people believe in the group consensus (e.g. god), and get to contribute and gain the benefits of the group. Universities are a good example aswell, as they provide employment, teach skills, and foster community and independence.
