Eh, I don't really agree. since eyes are a natural extension of body language, it doesn't always tell the truth.
Somebody speaking confidently doesn't mean what they are saying is right.
Somebody who has anxiety and can't speak about the topic with confidence may be an expert on the topic but just can't talk without sounding unsure.
It's just body language, just gaze at something intently with an intense feeling while crushing your eyes a little bit, and people will think you are smart if you do it long enough. Of course you need to have some degree of energy to have focus.
I find sensitive people and intelligent people often have a "still" look in their eyes, not because they are dumb but because in normal environments they get information overload.
As for the blinking, possibly yes but I think most people are too stupid to see the details in somebody else's eyes like that, if such a person had this insight, then that person would also easily be able to tell from the other persons behaviour, actions and what they ask/talk about as well, no need to look at the eyes.
Otherwise we wouldn't have the salesmen, party people who have a knack and make a living out casting an illusion on other people that they are smart and know something you don't.
Just my 2 cents I could be wrong.
Case and point: A lot of actors aren't smart in real life, but they can replicate intelligence on screen. Politicians can do this to by reading off a script, or any reasonably good presenter you can think of. Maybe you actually think they are smart, but I doubt they actually are as intelligent as you think they are.
