But it is, because it ignores the reality of the situation. "People don't like to be constantly shown ads, and so if you don't show ads too much they might respond to the ads. They also say they want more truth in advertising so you should refrain from over the top advertisements that promise the moon." sounds like a reasonable logical argument. Except that practically speaking its not how it works and contradictory things often get you results. The main problem is that we're dealing with humans and also that logical arguments don't work well in heavily interconnected contexts.

As programmers we like to isolate and optimize and we will continue to run into a wall when we try to apply that in human contexts.
