11 RUles for Critical Thinking

1. All beliefs in whatever realm are theories at some level. (Stephen Schneider)
2. Do not condemn the judgment of another because it differs from your own. You may both be wrong. (Dandemis)
3. Read not to contradict and confute; nor to believe and take for granted; nor to find talk and discourse; but to weigh and consider. (Francis Bacon)
4. Never fall in love with your hypothesis. (Peter Medawar)
5. It is a capital mistake to theorize before one has data. Insensibly one begins to twist facts to suit theories instead of theories to suit facts. (Arthur Conan Doyle)
6. A theory should not attempt to explain all the facts, because some of the facts are wrong. (Francis Crick)
7. The thing that doesn’t fit is the thing that is most interesting. (Richard Feynman)
8. To kill an error is as good a service as, and sometimes even better than, the establishing of a new truth or fact. (Charles Darwin)
