Making things hard to read 'can boost learning'

So the Beeb reports that the boffins believe that pupils retain more data if they have to read it in Comic Sans.

Perhaps the subjects retain more data if presented to them in a horrible font because they believe that if they pass this test first time, they won't have to revisit the horror of staring at a page full of Comic Sans later on down the line.

They should come back to them a week afterwards and ask them if they remembered any part of the test. Then ask them if they would like to stare at another page of Comic Sans, or just answer with what they remember. They might be surprised how many of the subjects might get their memories back rather than go through that earlier ordeal again.
