This phobia trivia quiz has 50 free questions with answers and covers the fears people actually have and the strange names psychologists and internet forums have given them: spiders, heights, clowns, needles, the number 13, being without your phone, and the famously long word for the fear of long words. Alongside the vocabulary you will find the science: how the DSM classifies specific phobias, why blood phobia makes people faint when other fears do not, the Little Albert experiment, exposure therapy, and the god Phobos who gave fear its name. It works for a Halloween quiz, a psychology classroom warm-up or a pub round where everyone thinks they know what claustrophobia means. Questions run from easy household words to expert-level etymology. Every answer was checked against encyclopaedia entries and clinical sources before publishing.
