This explains a lot of things:
When high-ranking monkeys are shown images of other monkeys glancing one way or the other, they more readily follow the gaze of other high-ranking monkeys, Duke University Medical Center neurobiologists have discovered. By contrast, they tend to ignore glance cues from low-status monkeys; while low-status monkeys assiduously follow the gaze of all other monkeys.
The discovery represents more than a confirmation of what most people believe about their bosses, said the researchers. The findings reveal that gaze-following is more than a reflex action; that it also involves lightning-fast social perception.
Next time your boss ignores your suggestion, and does something stupid just like other executives, he's just acting like a monkey. Literally: http://www.dukenews.duke.edu/2006/03/plattshepherdneuro.html
