Readers using electronic books are less likely to absorb what they have read because the information is presented in simple fonts. Devices using such a clear, legible format encourage the brain to be ‘lazy,’ making it more difficult to take things on board, research suggests. The findings go against the conventional wisdom that legibility makes it easier for people to learn and remember information. For example, although teachers assume legibility makes it easier for kids to learn and remember information, unusual fonts and smudged, hurried handwriting are more likely to be absorbed by the readers. The research suggests that introducing information superficially harder to understand deepens the process of learning and encourages better memorization
