What does an IQ score actually tell us about a person and what can it miss? The answer is far more complicated than a single number, especially when we consider strengths, weaknesses, culture, education and real-world ability.

In this episode of Psychology, Actually, Dr Marianne Trent joins Dr Keith Jenkins to explore the history and evolution of the Wechsler Adult Intelligence Scale (WAIS), what IQ scores really measure, and how the WAIS-5 can provide a more detailed picture of cognitive abilities. They discuss cognitive assessment, working memory, processing speed, reasoning, dyslexia, traumatic brain injury, dementia and the impact of factors such as anxiety, fatigue, sleep and language. They also explore why two people can have the same IQ but very different cognitive profiles, and why IQ alone cannot determine how successful someone will be. The conversation looks at WAIS-5 UK, cultural and linguistic considerations, practice effects, and the future of intelligence testing.
