- Aerobic activity shows the most consistent cognitive literature; resistance training has growing support for older adults.
- Better vascular health, sleep quality, mood, and possibly neurotrophic support.
- Unlikely in a dramatic, reliable way.
- Physical activity associates with school-related attention; causality is messy.
- For general well-being, a walk often beats another dual n-back session.
- Trail-making-lite and visual-search after a walk make an honest “alertness” combo — still not IQ.
What kind of exercise?
Aerobic activity shows the most consistent cognitive literature; resistance training has growing support for older adults. Dose and adherence beat exotic protocols.
Mechanisms (high level)?
Better vascular health, sleep quality, mood, and possibly neurotrophic support. We skip hype about a single molecule as an IQ switch.
Will HIIT raise my Raven score next week?
Unlikely in a dramatic, reliable way. Acute exercise can briefly change alertness. Lasting IQ change is not why people should exercise.
Kids and PE?
Physical activity associates with school-related attention; causality is messy. Still a good idea for health.
Brain-training vs walking?
For general well-being, a walk often beats another dual n-back session. For a specific lab task, practice that task.
Games if you still want them
Trail-making-lite and visual-search after a walk make an honest “alertness” combo — still not IQ.

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? →IQ 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? →Are 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 — 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? →Can 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 — core g is largely heritable. The honest answer is that some gains are real and some popular claims are overstated.
Can You Increase Your IQ? →Genius IQ Level: What Number Counts as Genius?
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.
