In your opinion what causes christians to believe in Jesus

[Alan V]

The advertising industry would like a word.

Advertising is 60% pseudoscience, 40% copying what the next guy is doing.

I'm sure advertisers don't spend all of those millions of dollars without the supporting statistics which confirm that their advertising works, even if it is just registering their products in the minds of the public through mindless repetitions, earworms, and mnemonics.  At the very minimum, they are trying to prioritize their products.
