Online sample IQ questions
Remember, a real IQ test is given one-on-one with a psychologist administering the questions, but this online test can give you a sense of the different types of questions that are on typical IQ tests. Note the cultural bias in some of the questions.
A different type of cultural bias
A very different set of sample questions the "Chitling Test," a parody of IQ test questions based on knowledge that is part of many African American communities but not in main-stream US culture. No questions about "the Hague" on here...
Intelligence and savants
"This is the breathtaking story of Daniel Tammet. A twenty-something with extraordinary mental abilities, Daniel is one of the world’s few savants. He can do calculations to 100 decimal places in his head, and learn a language in a week. He also meets the world’s most famous savant, the man who inspired Dustin Hoffman’s character in the Oscar winning film ‘Rain Man’ This documentary follows Daniel as he travels to America to meet the scientists who are convinced he may hold the key to unlocking similar abilities in everyone."
It is worth watching to see how incredible mental abilities can sometimes arise from damage to the brain and often come with what some would consider pretty difficult deficits.
