People with IQs above their parents tend to move into a higher social class. People with IQs below their parents tend to move into a lower social class. Those with IQs like their parents tend to end up about the same.

NEW: UC San Diego has released a new report documenting a “steep decline in the academic preparedness” of its freshmen. The number of entering students needing remedial math has exploded from 1/100 to 1/8. They’ve had to create a second remedial class covering elementary and

Hot off the presses at @ICAJournal is a new article examining sex differences in achievement in reading, math and science across different countries and achievement levels. Using data from the international PISA assessment, the authors whether within-individual strengths and

Tools that track specific molecules in neurons have enabled researchers to probe previously unexplored aspects of neurobiology https://t.co/IObLkmEslj

Connectome datasets alone are generally not sufficient to predict neural activity. However, pairing connectivity information with neural recordings can produce accurate predictions of activity in unrecorded neurons https://t.co/EWaBaM7soD

It should seem obvious, but I still see people often missing this: summary genetic scores can be misleading if you don’t check for trait-specific effects. For traits like intelligence, some cognitive tests (e.g., VNR, matrix reasoning) show extra genetic effects not shared

What does "grade level" really mean, and does it still make sense in today’s classrooms? In this episode of The Human Intelligence Podcast, we sit down with Dr. Karen Rambo-Hernandez @krambohernandez , Associate Professor at Texas A&M University, 🔗

What happens when IQ tests stop working the way we expect? 🤔 In this episode, we talk with Dr. Michael Woodley of Menie about his study “The Reversal of Spearman’s Hypothesis in Incarcerated Populations and the Role of Non-Shared Environmentality.” https://t.co/olNLZVX04z

Ivy League schools rediscover, sometimes as if for the first time, that standardized tests predict success in college: 1. Dartmouth (Feb 5, 2024): “Several key findings guided our decision: First, standardized test scores are an important predictor of a student's success in

It was great to talk to Craig Frisby (University of Virginia) about test bias and IQ on the @RiotIQ podcast. Frisby has been grappling with bias and IQ testing for over 40 years, and he is a wealth of knowledge about what bias is (and what it's not). https://t.co/jm9RnkGpC2

I met Watson in 2008 at a Banbury conference with many intelligence researchers. After discussing my talk on brain imaging studies of intelligence, he asked me to submit a proposal for a symposium. He tried but failed to get funding.

What a change since 2007. I can't imagine writing an article this long now. But until I reread it a few minutes ago for the first time in many years, I hadn't remembered it as being particularly long. I guess it's not only readers' attention spans that have shrunk.

Thank you. All important points. I hope you’ll be working in this area.

The @ICAJournal has a new article by @rjhaier about the connections between IQ scores, genes, and brain functioning (with some evolutionary biology and environmental influence thrown in, too). It's an information-packed article that connects findings from different branches of

A recurring theme in social science coverage of genetics is a tarted-up version of Pandora's Box. If we find out the facts about genetic influence, >>>very bad things might happen<<< We might start engineering people who are distinguishable from the median Cornell
