Can intelligence be increased or improve?

Yes, intelligence can be improved, particularly fluid intelligence (problem-solving) and overall cognitive function, through activities like consistent education, learning new skills, exercise, and targeted cognitive training, though general IQ scores are relatively stable but can shift with major interventions or prolonged learning. While you can get better at IQ tests through practice (improving test-taking skills), genuine improvements come from enhancing underlying brain functions like working memory and executive control.

Can you actually increase intelligence?

Processing speed and executive function can improve with regular use of apps that present increasingly difficult logic puzzles and math problems. Physical activity, adequate sleep, and even mindfulness training have been linked to sharper mental performance and better IQ test outcomes.

Can IQ be increased after 18?

Yes, your IQ can potentially increase after 18, but it's complex; while fluid intelligence (problem-solving) may plateau or decline, crystallized intelligence (knowledge) grows with education and experience, and brain training/new skills can improve specific cognitive functions, leveraging neuroplasticity. Significant increases aren't guaranteed, but lifelong learning, new experiences, and healthy habits can boost mental ability and performance, even if the overall IQ score doesn't skyrocket.
