I find the best way to remember something is to actually learn it in the first place....
I suspect I'll have read about the research on this font and not just try to glean a possible answer from snippets of news.
The link to the RMIT website has a little bit more info.
They also have a chrome extension which allows you to highlight bits and pieces of text and switch to this font.
For me, it significantly slows down my "speed reading" and forces me to read, rather than guess.
Like they say, if you want to learn how to code, type code - don't speed read or watch video tutorials.
Might be interesting to see how this sort of memory "training"(?) works when you compare students who write notes, as opposed to type notes.
