> It is common for people to make conclusions on topics based on their experience and what they’ve read. We all do this since none of us can possibly fully research all topics. Normative, not substantive. "Other people speak without knowing the limits of their knowledge" is not a good reason to emulate them. Research is not about filling your bucket of known knowns: that's merely literature review. It is about converting unknown unknowns to known unknowns related to some question or goal, and then chipping away about the unknown-ness of whatever enables you to reach your conclusion. With this exploration of the limits of knowledge I hope comes some humility about what people are willing to state in such strong and unwavering terms. > If you can find a severely mentally disabled person who has learned college algebra then please present your evidence. Straw man. Who has claimed this? The question of who is given advantage in the educational system is not related to this strange fixation of yours. I can acknowledge that someone defined as "disabled" is "dis-abled" from performing certain acts. This is uncontroversial. I suspect you are hiding behind this innocuous claim to avoid having the more uncomfortable conversation about what you think actually holds people back in the educational system. So far you have said "some people are smarter than others". I proposed a way this could be explained. You seem to have rejected it, but have not replaced it with another theory of your own. > I think this topic is an emotional one for you and this is clouding your interpretation of what I have written. Yeesh. Good luck out there.
