>your fundamental nature is flawed. Take these steps to salvation.

When a cheap sales pitch uses the "you're flawed" format, it's usually telling people "we are all flawed, but here's how you can be morally superior to your peers" or "do this thing and you'll receive a divine reward/achieve enlightenment." The promised reward or feeling of superiority is what makes people want to hear the message.

It's cheap to tell an aging church congregation about the dangers of video games and internet pornography, because it let's people pat themselves on the back without making a sacrifice. It's a little harder to tell an audience of young professionals that they need to limit high dopamine activities to find low dopamine activities appealing, and given that it's a real call to action based on a reasonable, falsifiable claim, I don't think it's cheap advice.
