A study published in 2010 conducted by Jonathan Leval, Shai Danziger, and Liora Avniam-Pesso of of Columbia and Ben-Guron Universities looked at 1,112 judicial ruling over the course of 10 months concerning prisoner paroles. They found that right after breakfast and lunch, your chances of getting paroled were at their highest. On average, the judges granted parole to around 60 percent of prisoners right after the judge had eaten a meal. The rate of approval crept down after that. Right before a meal, the judges granted parole to about 20 percent of those appearing before them. The less glucose in judges’ bodies, the less willing they were to make the active choice of setting a person free and accepting the consequences and the more likely they were to go with the passive choice to put the fate of the prisoner off until a future date.
