People who feel powerful tend to overestimate their own stature, feeling larger than they are.
“Maybe there’s a physical experience that goes along with being powerful,” says Jack A Goncalo of Cornell University, who co-wrote the paper with Michelle M Duguid of Washington University. “For people who are less powerful, maybe other people and objects loom larger, and for the powerful everything else just seems smaller,” Psychologi­cal Science reports.
Plenty of research has shown that taller people are more likely to acquire power; taller people make more money, on average, and are more likely to be promoted. But the study is the first to show that power also makes people feel taller.
