Detterman's Bytes: On IQ test standardization

So true. Another Detterman's tidbit of expertise.

"As the saying goes, any fool can make a test and many do. The really important part of making a good test is the work done after the test has been devised. This is most often, but not always, done by commercial test producers. Producing an accurate, usable test can cost millions of dollars. Though it may be academics that develop the concept for tests, it is those who do the hard and often tedious work of standardizing the test that make it useful."
