I tried the episode about sunk cost fallacy, praised by Fluttershy, but I triggered so much on your overuse of the word "should" that I couldn't continue.

I am very aversive to this, since I realised that "should" is not a reason to do anything (and taking this further, doing things because of "reasons" runs cross to consequentialism).

Take a look at what Nate says about this, which is not exactly my point but close enough: http://mindingourway.com/should-considered-harmful/
