There were no leaps of logic made by me. I never indicated or said anything about genetics. I said that it’s clear some people can’t learn algebra and gave an extreme example of such a person by saying that an intellectually disabled person can’t learn algebra. I then said that I’m convinced that there is some level of “intelligence” required to learn algebra.

I said absolutely nothing about what percent of people this is true for and absolutely nothing about why this is true. I brought it up in the context of the article because saying that not everyone can learn algebra is as taboo in education as the thought that genetics plays a role in poverty and success in life in psychology. My reason for thinking this is responses like yours.

There are clearly people who can’t learn algebra: intellectually disable people are such an example. I believe some level of “intelligence” is require to learn algebra.

How can you conclude from what I’ve written that I haven’t thought much about my belief? How can it appear I have an axe to grind from what I’ve written? You have formed an image of me that is wildly incorrect. Do you initially assume that everyone who thinks not everyone can learn algebra has an axe to grind?
