According to research, the human brain processes visual information 60,000 times faster than text, yet our cognitive biases often lead to misinterpretations and errors. Solving brain teasers under time pressure activates the prefrontal cortex, the brain region responsible for decision-making and analytical thinking. It also boosts fluid intelligence—our ability to reason and solve new problems without prior knowledge.
IQ tests often include such riddles to measure logical reasoning, lateral thinking, and cognitive flexibility. Brain teasers are a powerful test of intelligence, logic, and mental agility. Studies in cognitive psychology suggest that problem-solving exercises like these enhance critical thinking, reasoning skills, and pattern recognition, key traits found in high-IQ individuals.
