Type II Error (from a public choice perspective)

We make the burden of proof so strict (analogously the 'alpha' level) that we seldom are able to reject the null hypothesis. As a result we are more likely to unknowingly accept the null hypothesis when it is false. This translates to 'overcautious' behavior.
