A study of 1.5 million cases found that when judges are passing sentences on days following a loss by the local city’s football team, they tend to be tougher than on days following a win. The study was consistent with a steady stream of anecdotal reports beginning in the 1970s that showed sentencing decisions for the same crime varied dramatically indeed scandalously for individual judges and also depending on which judge drew a particular case. A study at an oncology centre found that the diagnostic accuracy of melanomas was only 64 per cent, meaning that doctors misdiagnosed melanomas in one of every three lesions.
