>SAT scores among admitted students is the highest it's ever been. And the GDP of Venezuela as measured in bolívar is the highest it's ever been! "More comparisons on new SAT scores versus critical reading and math scores on the old SAT: A new 1200 corresponds to an old 1130. A new 1300 corresponds to an old 1230. A new 1400 corresponds to an old 1340. A new 1500 corresponds to an old 1460. But a new 1600 is just as perfect as an old 1600." https://www.washingtonpost.com/news/grade-point/wp/2016/05/11/why-your-new-sat-score-is-not-as-strong-as-you-think-it-is/?utm_term=.b01040feaf93 https://www.washingtonpost.com/news/grade-point/wp/2016/05/1...

This argument exactly is why I posted the older fact book. The recent change doesn't explain the uptick going on for the past 40+ years. Also even if you take off 40-60pts there's still a rising trend. Underestimate the caliber of the rising population at your own peril. The failing generation can only cry ageism for so long before their jobs are eaten.

  You may be aware of this, but just to add to your point, the Flynn effect[0] of IQs consistently rising pretty convincingly rebuts the idea that higher SAT scores are _only_ due to the test getting easier. [0] https://en.wikipedia.org/wiki/Flynn_effect https://en.wikipedia.org/wiki/Flynn_effect

    I avoided mentioning the Flynn effect because it tends to attract naysayers (see below, with some embarrassingly poorly structured studies pulled straight from google). The argument against the downfall of society stands pretty well on it's own without it though, mostly because there's no evidence the tests are getting easier (regardless of recent score changes a 1600 is still a 1600) and even less evidence the test takes are becoming less accomplished.

      What exactly is embarrassing about this study: http://www.pnas.org/content/pnas/early/2017/01/10/1612113114 http://www.pnas.org/content/pnas/early/2017/01/10/1612113114.

        Extrapolating data from 90 years of an isolated island nation to evolutionary timescales is the major assumption. The other weak foundation is the assumption that this gene should correspond to educational level. It was weakly correlated in the early 20th century, less correlated now, and we can't put any weight on to what it actually controls (maybe it's related to IQ, maybe it's delaying gratification, who knows, the writers don't claim to). I think it's a bold conclusion to leap from one genetic marker doesn't seem as strongly correlated to education levels among Icelanders to "cognitive genomics is on the decline".
