"Since its invention, the IQ test has generated strong arguments in
support of and against its use. Both sides are focused on the
communities that have been negatively impacted in the past by the use of
intelligence tests for eugenic purposes.

disagreement over their validity and even morality, highlights not only
the immense value society places on intelligence — but also our desire
to understand and measure it."
