I didn’t know I had a reading disability, which is likely undiagnosed dyslexia/ADHD/ASD (per Neurologist), and for most my life I’d miss a lot of mistakes.
When I type I still miss many mistakes a day…

BUT when I review others work I find a lot of their mistakes. I was doing this before I had a clue about my own issues. I’ve corrected test (<-- I meant TEXT) as a part of my jobs from many types of persons ranging from artists to people with lit PhDs. My guess on this is when I quality control others I don't assign the standard value of the words being "read words" but something more akin to patterns with incorrect variables.
