Mensa - The largest and oldest society for people with high-IQs in the world. Mensa is the Latin word for "table".
IQ - A means of measuring human intelligence. A person’s IQ is usually ascertained by making them sit a standardised test. Some have criticised these tests as a means of evaluating intelligence, claiming that they ignore much of what it means to be intelligent.
Conspiracy theories - Theories that explain world events by blaming shady groups of powerful people operating in secret. Some conspiracy theories have a basis in fact, but many more of them are completely invented. What is more, they often play on dangerous prejudices such as antisemitism. It's worth being especially cautious and critical when you come across accounts that ascribe enormous agency to small and secretive groups.
