Assessing lateral thinking: validity, reliability, and universality using a novel verbal test

Abstract

Lateral thinking, a key component of creative thinking, is crucial in problem-solving, scientific discovery, and everyday life. However, its assessment remains challenging due to its elusive nature. This study proposes and validates a novel verbal test to objectively measure lateral thinking. The test, consisting of triads of words with subtle associations, requires subjects to find commonalities between seemingly unrelated concepts. The study involves three groups: two student groups and one engineering group. Statistical analysis reveals that the test demonstrates validity, reliability, and representativeness. Notably, the probability distribution of the measured parameter shows low deviations from the normal law, suggesting that lateral thinking, like general intelligence, is a relatively universal personality trait. This work contributes to a deeper understanding of lateral thinking and provides a validated tool for its assessment, promoting creativity in education and various other fields.
