[...] The researchers went on to theorize that getting power causes people to focus so keenly on the potential rewards, like money, sex, public acclaim or an extra chocolate-chip cookie— that they become oblivious to the people around them.
Indeed, the people around them may abet this process, since they are often subordinates intent on keeping the boss happy. So for the boss, it starts to look like a world in which the traffic lights are always green (and damn the pedestrians). Professor Keltner and his fellow researchers describe it as an instance of "approach/inhibition theory" in action: As power increases, it fires up the behavioral approach system and shuts down behavioral inhibition.
The corollary is that as the rich and powerful increasingly focus on potential rewards, powerless types notice the likely costs and become more inhibited [...]
