In the educational system, there is a concept of "useful hardship" that is used to make it harder to do common tasks. This forces the student to abandon stereotyped thinking, act creatively and better absorb new information. Recently, a typeface has been created that is itself a "useful hindrance" and helps to train students' memory.
The authors of the development from RMIT University in Melbourne, Australia, called their brainchild "Sans Forgetica". This is the first font in the world that allows you to remember what you read faster and more accurately. It's all about the combination of empty spaces in the writing of letters - it is chosen in such a way as not to tire the brain, but to stimulate it.
If the text is written in the same font, it merges into a single "array", and it is difficult for the brain to isolate the meaning from the letters. If the fonts are different, attention is spent trying to understand between them and catch the general meaning. And Sans Forgetica has become a kind of golden mean - it's picky enough, but at the same time, it makes the brain connect to grasp the meaning. The effectiveness of the approach has been tested and proven on hundreds of university freshmen.
