The less you know about finance the better

Everywhere you turn these days, some bigwig policymaker is talking about
the importance of financial literacy education.
The only problem is, there’s a fair amount of evidence that a lot of what we do
to teach better financial habits, like courses in high school, doesn't work.
Maybe we should ignore real-world complexity altogether
and just teach people financial rules of thumb.
