When it comes to big business, appearances it seems, matter a lot. Companies tend to be more profitable if they have a chief executive with a face rated by observers as being more competent, dominant and mature.

Similarly, companies with a chief executive judged to be a good leader, based purely on his facial appearance, also tend to be more profitable. These associations still hold even after controlling for the influence of age and attractiveness.

I wonder if the same applies to presidents.
