How much thought?

To find out how much thought has gone into an opinion, ask the following questions:

1. What evidence would prove X wrong?
2. If you were a lawyer representing the other side, what’d your argument be?
3. What do you want to be true?
4. What’s the best critique of X you’ve come across?
5. Who’s the smartest person who disagrees with X?
6. Where doesn’t X apply?
7. What are the tradeoffs?
8. If X turned out not to be true, what do you think is the next best hypothesis?
