Rapid Reasoning Response (3Rs)
The 3RsTest offers a sensitive, reliable, and valid measure of IQ, using highly efficient scientific methods.
The Rapid Reasoning Response (3RsTest), developed by the London Psychometric Laboratory, is a brief 5-minute assessment designed to measure general reasoning ability, a core component of IQ. Unlike IQ, reasoning ability excludes vocabulary, cultural literacy, and other complex acquired knowledge. Petrides (2020) suggests that IQ's significance is often overstated in assessments, overshadowing broader aspects of real-life intelligence. However, IQ remains an essential dimension in comprehensive evaluations. The 3RsTest offers a sensitive, reliable, and valid measure of this crucial IQ component, using highly efficient scientific methods.
