Sure, there's also clever and there's cunning and it's been argued that physical agility and dexterity, and social interpretation and navigation (and even physical navigation) are types of intelligence. I'm just not sure the ability to vomit up academic-sounding gobbledegook is any sort of intelligence more than it is a parlor trick.

You can convince a room full of modestly intelligent people that you can read minds or speak to the dead with cold reading and other tricks. There is no shortage of tricks to appear not as you are. It helps to be attempting to trick someone lesser than you in some way, but it's not necessary.

I've never seen or heard anything out of Harris, even when I agreed with it, that struck me as insight.
