If you were in jail and you had a parole hearing coming up, would you rather have it in the morning or the afternoon? It doesn't really matter as long as you present a good case, right? As it turns out, the timing of your hearing matters quite a bit.
A study conducted by the Department of Management at Ben Gurion University showed that the number of decisions a judge has had to make in a row, and how long it's been since he's eaten, drastically affects the outcomes of these hearings. The more decisions that a judge makes consecutively, the less of a chance a prisoner may have of going free. (So if you ever have to schedule your parole hearing, try for one of the first slots in the morning or right after lunch!)
This phenomenon doesn't just apply to judges, though. We all tend to suffer from decision fatigue, and when we do, it can lead us to bad choices.
