Experiment to study effect of smiling on leniency in judicial matters


A dataset with 68 observations on the following 2 variables.

Leniency Score assigned by a judgment panel (higher is more lenient)
Group Treatment group: neutral or smile


Hecht and LeFrance conducted a study examining the effect of a smile on the leniency of disciplinary action for wrongdoers. Participants in the experiment took on the role of members of a college disciplinary panel judging students accused of cheating. For each suspect, along with a description of the offense, a picture was provided with either a smile or neutral facial expression. A leniency score was calculated based on the disciplinary decisions made by the participants.
