Understandable. My feelings with homework is that it is an exercise. In college/university it was optional for us. Didn't effect your grade, it was recommended review essentially. Aka if you aren't sure you know what you need to know, so look at this if you wanr. If you'd struggle, study. If you don't. Ignore it.

Unfortunately telling 8 year olds some people don't need to do homework, doesn't roll over as smoothly.

"You can't spell read Jimmy, you keep writing reed; which makes you sound dumber than you are" doesn't work well as a response

Cool story. Literally none of it worth listening in a meaningful way, but you have seeming not retained how science, stats, and studies work.

Our understanding of science constantly changes as we learn new things. Do you think we shouldn't teach kids science because we might learn something new that shows what we used to know was wrong?
