I grew up in a country which is weird: it's a mix of people from the old generation who mainly have basic education and then the next generation over has a high proportion of University educated (this, by the way, applies to my extended family).

The latter simply have a higher tendency for thinking before reacting (even though they're older) which is much rarer in the former. Doesn't mean the latter don't have emotion, it means they're less prone to unthinkingly react on emotion alone.

I've also seen a similar effect in other countries I lived in.

In my experience and as you say, Education doesn't negate emotion, what it does is make people more prone to first think (which might mean they stop themselves) rather than immediatelly react on emotion alone.

In addition to that it also gives people a larger based of information to, when they think, judge things in a more informed way.

So, repeating myself, the more highly Educated are not immune to being scammed, they're just more resilent to simpler scams because there's they have a higher tendency to think rather than just blindly react. If you want to scam people who tend to think and have a broader base of information, you have to be more subtle (hence, as I pointed out, using techniques like a lot of the "progressive" Press like The Guardian or the New York Times uses in their Gaza coverage such as subtly portraying Israel and Israelis as more important and trustworthy - they "are killed" and their authorities "say" - and Palestinians as less so - they "die" and their authorities "claim" - the kind of subtle manipulation anchored on modern psychology technique which you don't see in less highbrow media.

By the way, life experience (emphasys on "experience" - merelly being old doesn't count) confers the same effect of tending to stop and think before plunging into things.

That said, I've seen plenty of highly educated people react in stupid ways driven by emotion, it's just less likely.
