<p>Right^. You have to account for being human.</p>
<p>I have long suspected one crucial difference in whether some kids stick with STEM goes back the the SES issue, with repect to the quality of the specific high schools and the breadth they can offer. What I’m going to say would still need to be further broken down (ie, studied) to get any sort of an analysis; eg, you’d have to break down for different categories of SES status and the hs those kids happen to attend:</p>
<p>Nearly all hs offer, eg, AP calc. Where there is a harsh limit, the other APs seem to be one English, one history, and bio. In contrast, many high SES high schools, we know, are pushing upwards of 20+ offerings. </p>
<p>That means, at my old hs, outside DC (more heterogeneous than in my day, but trust me, high SES,) kids are exposed to AP (or even honors) psych, IR and/or govt, econ, art, CS, multiple languages, etc. Other courses can include world affairs, soc/anthro, it goes on. These kids have a better first chance to identify and refine their interests and strengths. </p>
<p>In contrast, the bright kid at a limited hs may do well in math/sci and have that be the limit of his exposure – he sees his successes in that framework- and (don’t you think?) defines his possible future in that direction. Had he had other academic experiences, his initial vision may have been broader. Instead of saying, I do well in math, I’d like to be an engineer, he might say, I do well in aplying economic theory, hmmm. Or the opp to help people through psychlogy interests me.</p>
<p>Now, I wonder how many kids whose choices and exposures were limited, get to the college buffet and, no longer restricted, realize the breadth of their options? Get truly excited about other directions?</p>
