Each of us has a great range of talents and skills, and we all have untapped potential. Although there is still controversy surrounding the idea of a measurable IQ ("intelligence quotient"), the tests remain one way to stretch your ability to think in different ways. Challenge Your IQ looks at the issues surrounding the test itself and what it attempts to measure.
