The Reasoning Test Psychologists Still Can't Explain

Why do almost all of us struggle with a simple reasoning test, yet get it right the moment it’s about a pint in a pub? This week, Professor Hannah Fry and Michael Stevens take on the Wason Selection Task, one of the most intensely studied problems in the history of psychology.
