Childhood Adversity Blunts the Social Benefits of Intelligence

We often assume that a higher IQ leads to better social outcomes, like being more trusting and cooperative. But new research suggests that your childhood environment might be the "volume knob" for that advantage.

Discovery Redefines the Architecture of Thought

New research challenges the long-held belief that the brain makes decisions in a simple, top-down hierarchy. By discovering decision-making signals in the primary somatosensory cortex, researchers have revealed a system of bidirectional feedback loops that could be the key to building the next generation of energy-efficient, truly intelligent AI.

Edge of Chaos: Why Pigeons Refuse to Become “Machines”

Researchers found that pigeons rewarded for any behavior sequence still refuse to settle on a single "best" path. This "edge of chaos" behavior suggests a deep-seated biological need for flexibility over efficiency.

High IQ and High Status Share the Same Genes

A new study reveals that genetics explain up to 98% of the correlation between IQ and socioeconomic status. Researchers found that while upbringing matters, innate intelligence—driven largely by heredity—is the primary predictor of adult success.

Hearing Trouble in Crowds Linked to IQ, Not Ears

New research challenges the assumption that difficulty hearing in noisy places is always linked to hearing loss. Instead, the study found that cognitive ability is strongly tied to how well people process speech amid background chatter.

Smarter Minds Predict Better: IQ Linked to Sharper Life Forecasting

New research reveals that individuals with higher IQs are significantly better at predicting future outcomes, leading to smarter decision-making. Using data from the English Longitudinal Study of Ageing, researchers assessed how accurately people over 50 could estimate their own life expectancy. High-IQ individuals were found to make more precise forecasts—errors were less frequent and less extreme compared to their lower-IQ counterparts.

Early Baby Behavior Predicts Adult Cognition and Intelligence

A new study reveals that cognitive tests in infancy can modestly predict intelligence three decades later. Researchers followed over 1,000 twins from seven months of age, measuring behaviors like vocalization and novelty preference to assess early cognition.

Silent Switches in DNA Gave Rise to Human Intelligence

Despite sharing over 98% of our DNA with chimpanzees, humans possess strikingly advanced cognitive and emotional abilities. A new study reveals that rapid shifts in gene regulation—rather than changes in protein-coding genes—may explain this leap.

Study Challenges Myths About Cannabis, Brain Health, and IQ

A study spanning 44 years and involving over 5,000 men challenges long-held beliefs about cannabis and cognition. Researchers found that cannabis users experienced slightly less cognitive decline from early adulthood to late midlife compared to nonusers.

Brain-Wide Connections Predict Human Intelligence

A recent study explores how connections across the entire brain predict human intelligence, moving beyond traditional focus on specific brain areas like the prefrontal cortex. Using fMRI data from over 800 individuals, researchers analyzed communication between brain regions to predict fluid, crystallized, and general intelligence scores.

Huntington’s Gene Enhances Early Brain Growth and Intelligence

A study reveals that the genetic mutation causing Huntington’s disease (HD) enhances brain development and intelligence in early life, but leads to degeneration in adulthood. Children with the HD gene exhibit larger brains and higher IQs than those without the mutation.
