To Increase Willpower, Give in

In a famous study, participants smelled and were shown cookies but some were asked to eat radishes. Afterwards, the participants were asked to solve a puzzle. Radish eaters made far less attempts and took less than half the time to solve the puzzle vs. the chocolate-eating counterparts. In other words, those who exercised will power depleted it.

So if you want to increase will power, give in every once in a while.

Judge Early

A case study finds that Israeli judges favorable rulings went from ~65% to ~0% w/in each decision session and abruptly returned to ~65% after a break.

In one case of 3 prisoners with comparable sentences, the odds favored the prisoner who appeared early in the morning — and he got parole. The Arab Israeli prisoner, and thew Jewish Israeli prisoner (whose sentence was shorter than the man released) were denied parole. They were just asking for parole at the wrong time of day. Case after case mentally tired the judges.
