Hard-to-read fonts make for better learning, scientists say

In Princeton University study, paid volunteers were asked to learn fictional information about different types of aliens; those reading harder fonts recalled more when tested 15 minutes later, the BBC reports. The 28 volunteers had 90 seconds to try to memorize a list of seven features from three different types of aliens, an effort to re-create learning that happens in a biology class. One group looked at the lists in 16-point Arial pure black font, thought of as easy to read, while the other looked at it either in 12-point Comic Sans MS 75% greyscale, or 12-point Bodoni MT 75% greyscale. On average, those with the harder-to-read fonts remembered 14% more.
