The effects of little pushes are complicated. Vaccination is about little pushes.

Don’t waste time trying to make him think that Christianity is true!

The difference is that many Christians already argue that one should be Christian because it's the moral thing to do and it's socially beneficial. Christians don't engage in the same behavior of trying to make people think it's true than atheists do.

Christian missionaries actually do a lot of socially beneficial work in order to convince people of Christianity.

As far as "traditional wisdom" goes it gets interesting. I don't think that Christianity grows in China because the Chinese consider it traditional wisdom.

Mormons argue that the fact that the religion grows as fast at it does is a sign that it's true. They don't see it as a religion of the past but as one of the future.

Despite talking about ancient wisdom New Age folks use the word 'new' as part of their brand.

I think it's very useful to understand why certain movements win and move past your first stereotypes and actually seek understanding. Even Hitler who wanted to bring back traditional values was very clever in painting the status quo as going to end soon and the future as either his nationalism or communism.

He made it the cool philosophy that the young people at the universities wanted to follow before he had success with elections.
