The Relationship Between Intelligence and Planning Depth.

Researchers have found that people with higher IQs are quicker when solving simple tasks but slower when dealing with complex problems. Using personalized brain simulations of 650 subjects, they observed that brains with reduced synchrony between areas tend to “jump to conclusions,” whereas brains of higher-scoring individuals take longer but make fewer errors. These findings could significantly impact our understanding of brain function and may be applicable in treating neurodegenerative diseases.
