@BenWinegard @JamesLingford @sillyolyou @rasmansa @CathrynTownsend @LTF_01 @jonatanpallesen Daily cognitive performances do not look like what are predicted by theories in BG and so called intelligence research. https://t.co/6YHegMOp6V https://t.co/psyOhMJMgQ

@PrDemography @WiringTheBrain @nntaleb @PrometheusAM @SGM63 @RobertPlomin Intelligence research is just built on repetitive numbers whose scientific value is unknown. The assumptions of ergodicity are shown to break down when tested. Basically day to day congnitive performance cannot be explained by the litterature. https://t.co/6YHegMOp6V https://t.co/zmtwFCJon7

@marliekevk @yana_fandakova It is, but only because people have barely studied true fluctuations in IQ (exception below). People will have a *mean* trait IQ, but non-negligible, and non-unidimensional variation around that mean. Tablets/phones are going to transform this field imo https://t.co/pcGXT98gPH
