Question above is pretty blunt but was doing a study for a college course and came across that stat. How is that possible? My high school sucked but I was well equipped even with that sub standard level of education for college. Obviously income is a thing but to think 1 out of 5 American adults is categorized as illiterate is…astounding. Now poor media literacy I get, but not this. Edit: this was from a department of education report from 2022. Just incase people are curious where that comes from. It does also specify as literate in English so maybe not as grim as I thought.
It’s a self-reinforcing cycle. If you write directions at too high a level, people don’t read them and call support instead so someone can explain the directions with more and smaller words. So if you’re writing the directions and taking support calls, you have an incentive to try to write your directions at a low reading level to reduce your future support burden. (That doesn’t make you any good at it.) Which, if your hypothesis is correct, hurts the readers’ ability to read complex sentences a little bit in exchange for reducing your support burden by a lot.
