AI summaries do your hardest reasoning for you. Here is what 2025 research shows about the cost to critical thinking, and how to keep your judgment sharp.
That 25-word chain claiming you are one of the smartest people on Earth is built to be shared, not to measure IQ. Here is what it really tests.
Critical thinking predicts real-world outcomes better than IQ, even after controlling for intelligence. Here's the evidence and how to build it.
AI beats humans at chess and coding but still lacks common sense and real-world judgment. Why the gap persists and what it reveals about being smart.
Machines ace IQ-style tests but cannot match a toddler's hands. Moravec's paradox shows why raw intelligence is not real-world smarts.
Critical thinking is not intelligence or doubt. It is four repeatable moves. What research says AI changes, and five exercises that train it.
Free instant-result IQ tests are everywhere again. Seven psychometric checks reveal whether an online IQ score means anything at all.
IQ is still the strongest single predictor of performance, but emotional intelligence pays off in emotionally demanding work. What the meta-analyses show.
AI intelligence now costs 280 times less than in 2022. Here is why that raises the value of human judgment, verification, and question-asking.
Psychologists say the rarest intelligence is integrative: connecting unrelated fields. Why tests miss it, seven signs you have it, and six ways to build it.
A chemistry professor is teaching thermodynamics with AI-generated songs. The research says musical mnemonics work — with rules. Here is how to use them.
Free IQ tests with instant results measure something — just not clinical IQ. How to read online scores, spot gimmicks, and when real testing is worth it.
An IQ test and a dementia screening aren't the same. Here's what each actually measures, why people confuse them, and what a top score really means.
Does emotional intelligence matter more than IQ? The research is more nuanced than the headlines. Here's what EQ really predicts about real-world success.
As AI floods the world with fast analysis, human judgment is the scarce skill. What judgment is, why it is rising in value, and how to build it.
Science no longer treats intelligence as one number or one brain region. What the interdisciplinary view of intelligence means for understanding your own mind.
A high 'financial IQ' quiz score proves subject knowledge, not intelligence. Here is what IQ tests really measure and why real-world reasoning matters more.
Octopus intelligence evolved on a branch that split from ours 500 million years ago, with most neurons in its arms. What it reveals about the mind.
Three studies link heavy generative AI use to weaker critical thinking via cognitive offloading. What the research found and how to protect your mind.
Phishing beats smart people by attacking attention, not intelligence. The psychology behind it and the 7-check habit that actually stops credential scams.
What collective intelligence research shows: why groups can beat their smartest member, the conditions that make it work, and how AI borrows the idea.
GPT-5.6 launched with big intelligence claims, but IQ cannot apply to AI. What IQ tests measure, what benchmarks measure, and how to read the difference.
AI chatbots get health answers wrong about half the time, research shows. Seven concrete critical-thinking checks that catch AI errors before they cost you.
New neuroscience shows single human neurons compute more than we thought, and bigger neurons track with higher IQ scores. Here is what it really means.
AI keeps posting big scores on human tests, but IQ tests cannot measure machine minds. Here is what intelligence tests really measure, and why it matters.
AI writes essays yet fails simple reasoning puzzles humans ace. Here is what benchmarks like ARC-AGI reveal about the gap between LLMs and human intelligence.
A 2025 study links heavy AI use to weaker critical thinking. Here are the real-world reasoning skills that gain value, and how to use AI without dulling them.

Which quirky habits does research link to high intelligence, from mind-wandering to night-owl sleep, and how to read the claims without overstating them.
Research shows intelligence does not reduce cognitive bias, and can enlarge the bias blind spot. Here is why smart people rationalize and how to think better.
