The Biological Roots of Intelligence
n 1987, political scientist James Flynn of the University of Otago in New Zealand documented a curious phenomenon: broad intelligence gains in multiple human populations over time. Across 14 countries where decades’ worth of average IQ scores of large swaths … Continue reading

Intelligence IQ Tests: The Interplay of Motivation, Cognitive Functioning, and Affect
The Intelligence Quotient (IQ) tests and the corresponding psychometric explanations dominate both the scientific and popular views about human intelligence. Though the IQ tests have been in currency for long, there exists a gap in what they are believed to … Continue reading

The causal influence of brain size on human intelligence
There exists a moderate correlation between MRI-measured brain size and the general factor of IQ performance (g), but the question of whether the association reflects a theoretically important causal relationship or spurious confounding remains somewhat open. Previous small studies (n 〈100) looking … Continue reading

The Mystery of Intelligence
Few questions have generated such passionate discussions in the scientific community than those related to intelligence and intelligence testing. To give some examples: Arthur Jensen (1969) published an article in the Harvard Educational Review (HER) titled “How much can we boost IQ and … Continue reading
The Diet That Lowers Your Intelligence
The diet causes lower intelligence and 50% more laziness. High-fat foods can reduce intelligence in just 9 days, research finds. Cognitive performance reduced by 20% in just over a week after eating a high-fat diet. The study on rats fed … Continue reading

Intelligence is associated with the modular structure of intrinsic brain networks
General intelligence is a psychological construct that captures in a single metric the overall level of behavioral and cognitive performance in an individual. While previous research has attempted to localize intelligence in circumscribed brain regions, more recent work focuses on … Continue reading

The Role of Intelligence in Social Learning
Studies in cultural evolution have uncovered many types of social learning strategies that are adaptive in certain environments. The efficiency of these strategies also depends on the individual characteristics of both the observer and the demonstrator. We investigate the relationship … Continue reading

Brain-imaging modern people making Stone Age tools hints at evolution of human intelligence
How did humans get to be so smart, and when did this happen? To untangle this question, we need to know more about the intelligence of our human ancestors who lived 1.8 million years ago. It was at this point … Continue reading

Your Environment Could Be Changing Your IQ on a Genetic Level
The nature-versus-nurture argument of intelligence just got a lot more complicated with the discovery that the environment can modify the expression of a key gene in the brain, affecting intelligence far more than we previously thought. Such a finding may … Continue reading
