In Milgram's 1961 obedience experiment, 65% of participants were willing to deliver what they believed was a maximum 450-volt electric shock to another person — simply because an authority figure told them to. That finding changed how we understand obedience, authority, and human nature, and it is just one of the remarkable studies covered in this quiz.
50 hard questions spanning the most important experiments in psychology (Milgram, Stanford Prison, Pavlov, Asch, Harlow, Bobo doll), foundational theories from Freud, Skinner, Jung, Rogers, and Maslow, key cognitive biases including Dunning-Kruger, anchoring, and the fundamental attribution error, and modern developments like CBT, positive psychology, and Kahneman's dual-process theory.
Each round presents 10 randomized questions from the pool of 50, with four multiple-choice options and instant feedback after every answer. Your final score comes with a performance tier and shareable results.
The most frequently cited experiments include Milgram's obedience study (1961), the Stanford Prison Experiment (1971), Pavlov's classical conditioning with dogs (1897), the Little Albert study by Watson (1920), Asch's conformity experiments (1951), Harlow's rhesus monkey attachment studies, and Bandura's Bobo doll aggression research (1961). Each transformed our understanding of human behavior.
The Dunning-Kruger effect is a cognitive bias identified by David Dunning and Justin Kruger in 1999 in which people with limited knowledge or competence in a domain greatly overestimate their own ability. Conversely, those with genuine expertise tend to underestimate their competence relative to others. Their research earned an Ig Nobel Prize in 2000.
A psychiatrist is a medical doctor (MD or DO) who completed medical school and a psychiatry residency; they can prescribe medication and diagnose mental disorders. A psychologist typically holds a doctoral degree (PhD, PsyD, or EdD) in psychology and specializes in assessment, testing, and psychotherapy. In most U.S. states, psychologists cannot prescribe medication, though a few states have granted limited prescribing authority.
