Font legibility

Just saw this article claiming that a harder to read typeface improves
memory retention:

The theory is that forcing people to concentrate harder helps memory. I
believe that, but I think there are better ways to improve
concentration. I wouldn't want deliberate reduction of legibility to
become a strategy that gains ground. That could have unfortunate
accessibility side effects - while the proponents argue it's "good" for
cognitive accessibility. :(
