About your aside, while all of that is true, the inverse isn't. Not everyone thinks everyone else has EHI. So if you have a lot of people telling you you have EHI, then you can feel confident in your own assessment of whether or not you have EHI.
That's an astute observation, but there is such a thing as flattery and compliments paid with an ulterior motive and it's not always easy to tell those apart from genuine recognition of a perceived positive trait.
For example, perhaps people are telling you you're smart because they like your er other assets. Or because they feel obliged to because you're their boss. Or because they know your parents. etc etc.
Bottom line, there's confounding factors that can throw the calculation way off.
