There’s an old trope that says justice is “what the judge ate for breakfast”. It was coined by Jerome Frank, himself a judge, and it’s a powerful symbol of the legal realism movement. This school of thought holds that the law, being a human concoction, is subject to the same foibles, biases and imperfections that affect everything humans do. We’d love to believe that a judge’s rulings are solely based on rational decisions and written laws. In reality, they can be influenced by irrelevant things like their moods and, as Frank suggested, their breakfasts.
The graph above is almost the visual embodiment of Frank’s catchphrase. It’s the work of Shai Danziger from Ben Gurion University of the Negev, and summarises the results of 1,112 parole board hearings in Israeli prisons, over a ten month period. The vertical axis is the proportion of cases where the judges granted parole. The horizontal axis shows the order in which the cases were heard during the day. And the dotted lines, they represent the points where the judges went away for a morning snack and their lunch break.
