The family relationship between film characters clearly affects the reactions in the viewers’ brain. Are we more prone to help the person that resembles us the most? Social neuroscientists have studied the effects of similarity by showing a re-edited version of the film My Sister’s Keeper to a group of subjects and by giving them a moral dilemma to consider while measuring their brain function by means of functional magnetic resonance imaging.
