Analysing your IQ

Discover how reading habits build crystallized intelligence, expand vocabulary, and increase cognitive capacity. Learn strategic reading approaches.
Reading is the primary way humans acquire crystallized intelligence—accumulated knowledge and vocabulary. Heavy readers consistently score higher on vocabulary and general knowledge tests that correlate with IQ.
Reading exposes you to new concepts, vocabulary, and ways of thinking. This builds semantic networks in the brain. Reading fiction develops theory of mind (understanding others). Non-fiction builds factual knowledge.
Vocabulary is one of the best predictors of overall IQ and remains stable or improves with age. Lifetime reading volume strongly predicts vocabulary size, general knowledge, and verbal intelligence.
Include fiction, non-fiction, and varied genres. Breadth builds diverse knowledge networks.
Choose books slightly above your comfort level. Easy reading doesn't build vocabulary.
When encountering new vocabulary, look up definitions immediately. Use them in context.
Summarize key ideas. Connect new information to existing knowledge.
Explaining ideas to others deepens understanding and reveals gaps.
Take an IQ test to measure your baseline before implementing these strategies.
Take IQ TestReading builds crystallized intelligence (vocabulary, knowledge) which is a component of IQ. Heavy readers consistently score higher on verbal intelligence measures.
Challenging non-fiction builds factual knowledge. Literary fiction develops social cognition. Both contribute to intelligence. Variety is key.
Consistent daily reading compounds over time. Even 30 minutes daily exposes you to millions of words annually. Quality and challenge level matter as much as quantity.
