What people are saying
Overall, discussions demonstrate a scientific tone, with posts highlighting the importance of the correlation coefficient (around 0.24) and referencing large meta-analyses, such as the one by Pietschnig et al., to validate the findings. The language and tone reflect curiosity and recognition of the study's role in refining our understanding of brain size and intelligence relationships.
Most discussions acknowledge the meta-analysis confirming a modest but consistent link between brain volume and intelligence, supporting the publication's conclusions.
Participants show active interest, referencing multiple studies and emphasizing the correlation value, indicating engagement with the scientific content.
Discussions involve citing specific research findings and methodological details, suggesting moderate but meaningful engagement.
The posts collectively recognize the significance of the meta-analysis in clarifying previous overestimations and encouraging further research, showing some impact on understanding scientific debates.
Abstract in brief
- The study systematically reviewed 88 research papers involving around 8,000 individuals to analyze the link between brain size and intelligence, finding a generally positive correlation.
- Although initial reports suggested strong links, the analysis shows that the actual correlation is modest and likely overestimated in past studies, suggesting publication bias.
- The findings indicate that while brain volume and IQ are related, brain size should not be directly viewed as a definitive measure of human intelligence or cognitive ability.]

Genetic Ancestry and Brain Surface Geometry Revealed by 3D Brain Modeling
This study explores how the 3D shape of the brain's surface reflects genetic ancestry across diverse populations, showing that cortical surface geometry can predict ancestry amidst complex migration and mixing events.
@RCKola5 @VoxCorvorum @OsamaBinnGuapo @Awk20000 @grok You are trolling there's no shot. Here's the largest meta study i could find https://t.co/rcZKNUQzpt thats 88 studies with r=0.24 https://t.co/VAn77wIzky here's 37 samples with r=0.33 https://t.co/V3Uf0BH6Tu here's a in-family study showing r=0.19, isolates the variable.

@misinthrope79 @AnthonyCumia 9/ https://t.co/2Kd8YtI40f https://t.co/LNw5svqsC1 I feel I've posted too much, good luck as I have 30+ pieces of research data and findings waiting after you go through these, I'll gladly summarize for you as well. (Take your time as the bell curve is, well, adorable trash).

@gertwiep @CRASSGENDER @Joycezondernaam @VerhoevenKylian @Joop_nl Exact, die flauwekul waar een meta-analyse van 88 moderne onderzoeken (n=>8000) van is die een correlatie van 0,24 vindt tussen herseninhoud en IQ. Blijkbaar hadden de pioniers op dit gebied 150 jaar geleden toch gelijk. https://t.co/D7PbBdSV96 https://t.co/k7O1iBkZZe

@Martymuth @Radix69123161 Objem mozku s inteligencí trochu koreluje (r=0.24, https://t.co/1a56TirfLo), ale nezdá se, že by mezi pohlavími byl rozdíl v obecné inteligenci. Muži jsou např. trochu lepší ve vizuálně-prostorových úlohách (možná souvisí se řízením), ženy zase většinou např. v těch jazykových.

@SecretBaboon @gcochran99 @vious_and_couth @SilverVVulpes @AlexTISYoung I referred to brain volume not "structure" or "activity". This meta-analysis found the correlation was exaggerated by publication bias but still robust: https://t.co/GZXwB13TzC
