I’m midway into this podcast. I would like to know if an analysis was done to see if there were any distinguishing differences or similarities within the white group with the scores of lower economic background etc &amp; Also in the other group. Plus other races were left out. If one group had more disparities I would think less opportunities of learning in &amp; outside of the home would be the cause of lower scores. Have any of these studies been done in other countries? I believe my SAT score wasn’t that great &amp; I put it out of my mind so I don’t remember. Both my biological parents were poor &amp; my bio mother didn’t go pass 4th grade. I was brought up in the foster care system until age 5/6 when I was adopted into a upper middle class family. There are always outliers of whatever background but like the host said it may take me twice as long to study but at the end I know the material as someone who can get it in 1/2 the time. All I know is that now I have a child who is mathematically inclined but if there is any area in his educational journey where he needs a boost I will think nothing of getting him a tutor b/c in the end education is the chance to independence &amp; freedom. The smartest people can make the dumbest mistakes &amp; or believe the earth is flat &amp; what not b/c we all have our interests, influences, biases…
