What is cognitive offloading?
Cognitive offloading is relying on external aids to perform mental work you could otherwise do in your head. Writing a number down, using GPS instead of memorizing a route, or asking an AI to summarize a document are all examples. It is a normal, ancient strategy. The open question is whether offloading too much, too passively, weakens the underlying skills over time.
Does the MIT 'Your Brain on ChatGPT' study prove AI lowers IQ?
No. The 2025 MIT Media Lab EEG study reported lower neural engagement and weaker recall when participants wrote essays with an LLM compared to writing unaided. Importantly, it is preliminary and not yet conclusively peer-reviewed, it involved a small sample, and it measured engagement on one specific task, not lasting IQ change. It is a useful warning signal, not evidence of permanent cognitive decline.
Can AI ever make us smarter?
Yes, used deliberately, AI can support rather than replace thinking. Offloading routine recall and busywork can free working memory for higher-order tasks like synthesis, strategy, and creativity. The benefit depends on staying an active editor and critic of AI output instead of accepting it passively. The tool itself is neutral; the habit around it determines the outcome.
What habits reduce the downside of AI use?
Treat AI as a draft partner, not a final author. Generate ideas or first drafts with it, then revise and rewrite in your own words so you still encode and understand the material. Keep practicing effortful skills (mental math, writing, navigation) regularly, and verify factual claims yourself. The goal is to offload trivia while protecting deep, effortful thinking.
Is this the same panic people had about calculators and search?
Partly, yes, and that history is instructive. People worried calculators would destroy arithmetic and that search engines would erode memory, and the reality was more nuanced than the fear. Those tools shifted which skills mattered rather than abolishing thinking. AI may follow a similar path, but its breadth makes mindful use more important, not less.
AI Habits: Effects on Thinking and Healthier Alternatives
| Behaviour | Effect on thinking | Healthier approach |
|---|---|---|
| Let AI write everything for you | Weaker recall and engagement with the material | Use AI to draft, then revise and rewrite it yourself |
| Outsource all memory to tools | Less retention and recall practice | Offload trivia, but keep practicing deep, effortful work |
| Accept AI answers without checking | Shallower understanding, error risk | Verify claims and use AI as a starting point, not the verdict |
| Skip the thinking, copy the output | Lost skill-building over time | Engage actively: question, edit, and learn from each answer |

What Is a Good IQ Score?
An IQ of 100 is exactly average; 110-119 is above average, 120 and up puts you in the top 10% (a genuinely 'good' score), and 130+ is considered gifted. IQ is built on a normal distribution with a mean of 100 and a standard deviation of 15, so most people cluster near the middle.
What Is a Good IQ Score? βIQ Percentile Chart: What Percentile Is My IQ?
Your IQ percentile tells you the share of people you scored higher than: an IQ of 100 is the 50th percentile, 115 is about the 84th, 120 is roughly the top 10%, and 130 is roughly the top 2%. The table below maps every major IQ band to its classification, percentile, and share of the population.
IQ Percentile Chart: What Percentile Is My IQ? βAre Online IQ Tests Accurate?
A well-designed online IQ test gives a reliable estimate of your reasoning ability, but it is not a clinical diagnosis β only a proctored test like the WAIS or Stanford-Binet provides that. This test is built on Raven's Progressive Matrices and CHC theory, scored on the standard scale (mean 100, SD 15), with an internal reliability (Cronbach's alpha) of about 0.85-0.92.
Are Online IQ Tests Accurate? βCan You Increase Your IQ?
You can meaningfully sharpen reasoning skills, working memory, and test performance through training and education, but raising your underlying general intelligence (g) substantially and permanently is not well supported β core g is largely heritable. The honest answer is that some gains are real and some popular claims are overstated.

A 'genius' IQ traditionally starts at 140, while 130 and above is labeled 'very superior' on modern tests. Scores that high are extremely rare, and the famous IQ numbers you see for historical figures are almost always estimates, not measured results.
