@JustineBateman Spot on. What’s wrong with a little joy?

@Liathetrader Get a Tesla.

@Liathetrader @Dostilline What’s the over/under on “prove it” comments?

@DamonAmendo @TyDunne Tye Dunne is an excellent writer. His style is engaging. But he is also like the Malcom Gladwell of sports journalism. The stories are entertaining but aren’t always true and he’s tries too hard to generalize and psychoanalyze things that he shouldn’t be based on a few.

@LargeFamDad Don’t interpret grade equivalents. The percentile ranks look great though.

[Mrrutexas @mrrutexas]

@Hitchslap1 @lu_sichu A lot of Gc tests load highly on g, and higher than Gf tests. It’s the Gf factor that becomes isomorphic with g so whatever is in common among Gf tests is the same that’s in common among all the tests.

[Mrrutexas @mrrutexas]

@Hitchslap1 @Hanuta159971 And when you combine the scores it is what in common that is mostly measured in the composite.

@OhioTate Wanna “bet” on it? 🤣

@avidseries Did we destroy or delay their capabilities? I don’t know the answer to that but if we did then that would be more important than any agreement.

@JAustinEDU Are ad hominem attacks part of the knowledge curriculum?

[Mrrutexas @mrrutexas]

@B4D_M0J0 What’s more American than a good olde conspiracy theory?

[Mrrutexas @mrrutexas]

@JShell085 g is what is in common. TheFlynn effect for example is due to changes in specific skills and not due to g. You can test these things in psychometric models. Does increasing skill in copying squiggly lines quickly mean you’ll learn across content areas more easily? I doubt it.

[Mrrutexas @mrrutexas]

@JShell085 I was thinking more of stratum i or specific skills (independent skills) and not what is in common among the broad abilities or tests. In other words you could improve iq but not g

@C_Hendrick @jon_hutchinson_ You wear a school shirt

[Mrrutexas @mrrutexas]

@JShell085 Within the hierarchical model it is the very specific abilities that might be more malleable but not g. And stability basically means the rank ordering of scores are generally stable across life (which is supported) and not that your intelligence doesn’t change, it obviously does

[Mrrutexas @mrrutexas]

@timothycbates That’s almost unbelievable.

[Mrrutexas @mrrutexas]

@marcportermagee They also tend to have, on average, brighter students.

[Mrrutexas @mrrutexas]

@boazbaraktcs I’ve watched them present the research findings on these kids for years and I’m always in awe.

[Mrrutexas @mrrutexas]

@davidzweig Teachers account for about 4% of the variance in achievement scores.

[Mrrutexas @mrrutexas]

@0Beanie05923291 @marcportermagee @MindofTorres These results are because ability differences in the students and not the schools. Control for IQ and the differences disappear. This was demonstrated many years ago.
