People use facial clues about your height to judge your leadership abilities.

In 2013, a group of psychologists, neuroscientists, and computer scientists from Europe and the US had a small group of participants look at portraits of 47 white men and 83 white women and evaluate them first on their height and next on their ability to lead.

The researchers found that people used factors in the photos like gender and face length to make guesses about people's height and then used these same factors when they judged their leadership qualities. Faces that appeared to belong to taller people were rated as belonging to better leaders.
