@ian_snow @Hitchslap1 wow great point, the IQ scale will need to be renormed if the population collectively increases their IQ by 1 SD. therefore, the increase would be meaningless because the mean wouldn’t change! zero sum!!! brilliant!!!!!

@ResearchBiology @calotonterias i know that brain lesion damage in this exact region eliminates sensory pleasure, to where a sweet taste will instead taste bitter. we can infer from this that this brain region must be in some way responsible for producing the sensation of pleasure

@ResearchBiology @calotonterias mesolimbic dopamine pathway? ventral tegmental area & nucleus accumbens? do you not think this is a reward circuit

[noname @jensen__effect]

@CognitiveMetric should we expect the SAT scores to be slightly inflated too due to self-selection effects (people who did better on the SAT would be more likely to report their scores)

[noname @jensen__effect]

@merdestinoincel bc evolution doesn’t naturally select for what is objectively best, it selects for what is “good enough”, it just targets local maxima rather than global maxima

[noname @jensen__effect]

@BarrakAli @Hitchslap1 proof

[noname @jensen__effect]

@calotonterias does this hold within families

@BecomingCritter ever heard of a scam? ever heard of a bargain? a ripoff?

@emirahera @Hitchslap1 why wouldn’t you want to be happy lol

@BasicHeresy @Hitchslap1 @timothycbates yes

@CognitiveMetric @Hitchslap1 sybaunga

@toocool46978 @waysxmany the key difference is that this person has 0 stimulation, while the teenagers have plenty of stimulation

[noname @jensen__effect]

@RichardHanania that’s a good goal, but i care about more than 1 generation, so i take into consideration regression to the mean

@PeterMmuo @johannesmkx 10 hours in one day is still 10 hours in one day. it’s overkill & gives diminishing returns

[noname @jensen__effect]

@PeterMmuo @johannesmkx it’s arguably more effective to study hard for like 4 hrs & then do light tasks for the rest of the day to allow your Default Mode Network(DMN) interact with the neural networks you formed today. It replays the neural sequences that fired earlier at 20x the speed

[noname @jensen__effect]

@_rakesh_pandey @johannesmkx if you’ve ever played video games, it’s analogous to how if you don’t wait long enough for items to despawn (or for the brain to integrate what you’ve learned into long term memory), your device can’t handle rendering everything & starts lagging a lot/performing bad

[noname @jensen__effect]

@_rakesh_pandey @johannesmkx our biology created these limits. we didn’t evolve to do mentally taxing work for more than 6 hrs a day, & so attempting to do so results in significant dopamine depletion & adenosine buildup, greatly decreasing the accuracy of our neural signaling/signal-to-noise ratio

@Wastertorp @cremieuxrecueil @ubiquitousnewt brother what LOL

[noname @jensen__effect]

@Hitchslap1 it’s outdated

[noname @jensen__effect]

@Hitchslap1 isn’t the average iq of college students ≈ 102 today? the estimates of this graph point towards a mean iq score of at least 115 imo, which contradicts the current studies i’ve read regarding college students & iq. maybe it’s outdated?

[noname @jensen__effect]

@thebenbranding_ @DearS_o_n a lack of it *fuels* each of these
