A Woman’s Story
<i>There were a lot of questions about numbers such as guessing the next number in a sequence. There were some logic puzzles, the kind where you have to figure out that it’s the baker who rides a bicycle and the mechanic who lives in the house with a red door. There were some strange questions where she was given a sketch of a three dimensional figure such as a cube with some missing pieces, and she had to guess which shaped piece would fill the missing space, or guess which of several other pieces was the same thing rotated or reflected.</i><p>This is essentially an IQ test, and what they discovered is that Gwen was highly intelligent. They then did the smart thing and judged her based on her demonstrated aptitude rather than on the prevailing prejudices of the day. Indeed, there was an obvious financial incentive to do so, which serves to remind us that <i>unfounded prejudice is unstable in a competitive market for labor</i>.<p>Nowadays, it is effectively illegal in the U.S. to give IQ tests to job applicants, and in the state of California it is illegal to give a black child an IQ test even when administered by a school psychologist as part of a professional assessment. To their proponents, such laws are mere "progress", but stories like Gwen's show how misguided these rules can be. When there is a clear incentive to discover the truth, objective assessments <i>undermine</i> prejudice rather than promoting it. It's a lesson we would do well to remember.
