BIAS OF THE WEEK

Social Norms

In one study, doctors received a monthly email with information on their performance relative to their peers, along with a tally of their antibiotic prescriptions compared to the average top performer. 

This intervention led to a 16.2% drop in inappropriate prescribing behavior. 

Social norms have a huge influence on shaping our decision making, especially if the group we are compared to share our circumstances.
