@SashaGusevPosts I appreciate your replies. Comparing simple twin-study heritability estimates for IQ against dynamic, complex model-based approaches is challenging because one is so simple other complex. I want to understand the strengths and trade-offs clearly, but its work.

Usually a grand lesson when there is a large gap in conclusions from different methods- it drives my curiosity to learn.

[Dub-A @Shunkup]

@beowulf888 @capitalismandf1 @SashaGusevPosts There is a big gap in Fluid reasoning and Height based on the paper, curious the reason. What papers are undermining the heritability in twin studies, also studies for importance of early environment? I only saw confirmation in my search that adult heritability is very strong.

[Dub-A @Shunkup]

@beowulf888 @capitalismandf1 @SashaGusevPosts Why the big gap between twin/adoption studies (IQ heritability ~50% in childhood rising to 70-80%+ in adulthood) and current PGIs (only ~5-16% variance explained for IQ/cognition, higher for education proxies)?
For height, PGIs now capture ~40%+ and are closing in on twin studies

@DogsBreakfastAZ @PhysInHistory How?

[Dub-A @Shunkup]

@cremieuxrecueil Would be a ~130 IQ if you believe modern SAT has such a relationship to intelligence. I do not- old SAT did, but newer SAT has too low a correlation to g IQ to establish the relationship... as I see it. People study for the test and that doesnt translate to life.

@HighlyCitedX BEeen playing around with old literature that says Tertiary speciation rates are ~0.05–0.3 events per lineage per million years, with species lasting 0.5–1+ million years. For the Homo lineage persisting over 2.5 million years, you'd expect just 1–3 descendant species. Thoughts?

@lonecrim I had high hopes for AI sorting empirical reality from our inherently biased worldview, but it seems more biased that humans. Like AI has a strong Overton Window filter.

@me_dhruvb @CitiusMag Track athletes need to manage their careers, 90% of their value is from Olympic years. If I was his coach id have him on a plan to peak in 2028 at 20. A medal there sets his path. An injury beforehand is major blunder. 20 is pre-peak- so its also not his lifetime best opportunity

@archeohistories Vikings flaunted their braids. I hear you cancel vikings for cultural appropriation!

@AndrewAtkin75 @charlesmurray Yes it amazes me how many experts dont see pay as a dynamic equilibrium between supply and demand. Care has a surplus because it is not a field rewuiring exclusive skills, academia is exclusive but the supply exceeds demand, banking turn over drives pay up amongst exclusive skill

[Dub-A @Shunkup]

@HighlyCitedX Yea, its confusing but in general the sister lineage can be the LCA. So yes Heidelbergensis was derived from LCA in my mental model, but not by much.

[Dub-A @Shunkup]

@HighlyCitedX Share and I will have a read

[Dub-A @Shunkup]

@HighlyCitedX HEIDELBERGENSIS is more erectus like in my assessment by age and synapomorphies (im on my own system here). LCA and sister are not mutually exclusive- it could be sister and LCA. I guess I didnt understand it was not potentially the LCA.

[Dub-A @Shunkup]

@HighlyCitedX So Bodo is 600k, you have the Mauer 1 "Jaw" at 600k. For me the model that Asian erectus (Java man) evolved into Heidelbergensis, which is LCA for Neanderthals, Denisovans, Sapiens is on sound empirical ground. Curious if there are any empirical busts others see?
