How many people do you know that won't believe anything they hear unless it's been "scientifically proven"? How many people do you know that will treat any scientific study as absolute truth? Do you think anything that is printed in a scientific journal to be true?

I would say that many people these days are like this. These are the people who get stuck in life and aren't willing to try anything or listen to anybody's ideas because it hasn't hasn't gone through a double-blind peer reviewed scientific study.
