The Halo Effect
Description of Study
Thorndike asked commanding officers in the military to evaluate a variety of qualities in their soldiers. These characteristics included such things as leadership, physical appearance, intelligence, loyalty, and dependability.
His goal was to determine how ratings of one quality bled over onto assessments of other characteristics.
He found that high ratings of a particular quality correlated to high ratings of other characteristics, while negative ratings of a specific quality also led to lower ratings of other characteristics. The correlations were too high and too even.
Results of Study
