There's a reason it's the cornerstone of http://www.paulgraham.com/say.html

Original thinking tends to be offensive. If you're right, you often can't go around saying you're right. You have to keep your thoughts to yourself. And if you have a scientific mind, you want to seek truths wherever they are.

If you get in the habit of actively trying to seek out radioactive truths, you'll stumble on some interesting ideas eventually. And I'd love to know anyone who genuinely makes it a habit (as opposed to doing it for social signaling).

You're right that the majority of people wouldn't be interested, because most people have deeply-held beliefs. Getting at original ideas requires a fluidity that often runs against natural instincts.
