In this journal, Kyoungmin Cho, Christopher M. Barnes, and Cristiano L. Guanara , the researchers were performing a quasi experiment to see if there was a relation between judges being tired and sentencing those who enter the courtroom. The researchers came up with the hypothesis that sleep deprived judges would sentence a person who committed a crime to a longer sentence than a judge that was well rested. For them to conduct this quasi experiment they used judges from 90 judicial districts and the defendants that were before those judges. Judges from Alaska, Hawaii, and Arizona where not include due to the fact those states do not participate in daylight savings. The defendants were U.S citizens of all different
backgrounds.
This test measured the time the defendants were sentenced to - not including probation or community service. The time of imprisonment was measured in months; anything over 470 months was consider life in this test. Further, there was a variable for the amount of sleep a judge had. Things like sleep deprived Monday were compared to a regular day Monday. The punishment patterns of a person's, criminal history, race, gender, and age were all controlled variables. The number of months a person was sentenced to was the dependant variable, whereas the number of hours a judge slept was the independent. In this quasi experiment, the independent variable was not manipulated and could not be manipulated. After comparing days of the week and seeing what the judges ruled, the researcher had enough significant values that stood at in their data. This means their null hypothesis was proven to be true. On tuesdays, thursdays and friday, there was no significant value demonstrating that the hypothesis was also correct. When the researchers ran the test for this quasi experiment for the daylight savings where people would gain a hour, there was no substantial numbers disproving their theory- this to also proved their hypothesis. Through this operation, the men were able to discover that sleep deprivation assisted judges in long sentencing. The researchers established that judges that lacked hours of sleep sentenced 5% more than judges that were rested. This experiment helps people to know that sometimes their punishment can be longer than usual due to the sleep deprivation of a judge. This could be the case for a hand full of defendants that enter the courtroom, today.
