📌 Key takeaways
- No.
- No.
- Evidence does not support matching teaching to “visual” or “auditory” learners.
- IQ is fairly stable but not fixed — education, environment and the Flynn effect all show it can shift, especially over development.
Do we use only 10% of our brain?
No. Brain imaging shows we use virtually all of our brain, just not all at once. The 10% claim is a persistent myth with no basis.
Are people left- or right-brained?
No. While some functions lateralise, healthy people use both hemispheres together. The “logical vs creative” brain split is a misconception.
Do learning styles work?
Evidence does not support matching teaching to “visual” or “auditory” learners. Good teaching uses multiple methods for everyone.
Does IQ never change?
IQ is fairly stable but not fixed — education, environment and the Flynn effect all show it can shift, especially over development.
