The correlation between intelligence and problem-solving speed

Contrary to popular perception, intelligent individuals don’t necessarily think faster. In fact, those with higher intelligence scores were only quick at handling simple tasks, whereas they took more time in solving complex problems than subjects with lower IQ scores, according to a study by the Berlin Institute of Health and Charité – Universitätsmedizin Berlin. The study used personalized brain simulations and found that brains with less synchrony among various regions were prone to making hasty decisions without waiting for upstream brain regions to process the necessary information for solving the problem. The research could lead to enhanced personalized medical interventions, including the planning of surgical and drug treatments, and even therapeutic brain stimulation.
