No disrespect to your stellar c.v., but my understanding of human behavior, as you put it, is essential to what I have been doing for a living since I left grad school in the late 1970s. Whether that understanding is "greater"" than yours is neither here nor there. It's not a competition.

Of course I am aware of the difference between self-esteem and hubris, but please enlighten me with your own explanation. (And feel free to use Google.)

By the way, what is that emoji at the end of your post? I don't use them so remain singularly ignorant of such doodads.
