What people are saying
Some discussions highlighted key findings such as the heritability of IQ and other psychological traits, with commenters using phrases like 'evidence for the strong heritability' and '70% of IQ variance attributed to genetics.' The tone varies from enthusiastic endorsement of genetic influences to critical skepticism, underscoring a nuanced dialogue around the impact of genetics versus environment in shaping individual differences.
Many discussions reflect a shared acceptance of the study's conclusion about the genetic basis of psychological differences, although some express skepticism.
The discussions exhibit a high level of curiosity and debate about the findings, with many users eager to reference and analyze the original publication.
While posts engaged in discussing methodologies, not all showcased high depth, as some focused on surface-level reactions.
There is a strong belief among users that the study's findings have significant implications for understanding human psychology and intelligence.
Abstract in brief
- A long-term study of over 100 sets of twins and triplets raised apart showed that about 70% of IQ variance can be attributed to genetic differences.
- Monozygotic twins raised apart exhibit similar personality traits and interests as those raised together, indicating a strong genetic influence on psychological traits.
- While genetics plays a significant role in psychological differences, this does not undermine the importance of parenting and education in a child's development.

Most liked on X and Bluesky@oconick1 Bouchard's 1990 study on "twins reared apart" is a disgrace. It's either plain stupid, or scientific fraud. @ScienceMagazine should investigate @jayjoseph22's claim that the authors hid key fraternal twin data.
