HT to Tyler Cowen for sharing these rules with his readers. They are dubbed “Cowen’s Three Laws.”
- There is something wrong with everything. 
- There is literature on everything. 
- All propositions about real interests rates are wrong. 
#1 and #2 are intuitive, but what about #3?
I read #3 as it’s easy to make claims about the future or that which is not certain; those claims are often wrong. Best to treat claims about what hasn’t happened with skepticism.
All three are useful reminders. Hope they help you too.
