NPR has a study that provides some data on this topic.
The point made is power changes how the brain operates.
I have always resisted being an executive.
So when people felt power, they really did have more trouble getting inside another person's head.
The paper cited is here. The conclusion from the paper is as follows.

tendency for the powerless to expend effort in understanding the
