Revealed Preferences is a term from economics that neatly encapsulates “watch what I do not what I say“. 

I see this as a good guiding principle in life. Ignore your own stated preferences, goals, pleasures and interest. Analyze your actual behavior to determine your own Revealed Preferences. 

It also has socio-political utility. President Trump was the shocking Revealed Preferences of more swing state voters than anyone thought. 

The best predictor of future behavior is past behaviors, says psychology.
