Here's a phenomenon that's long intrigued me. The page on my website (www.PsychologicalTesting.com) that gets the most visits is not the homepage, not by a longshot. The homepage is the red line above. I get the most hits (hundreds per day) at iqtest.htm, my page about IQ testing, shown by the blue line above. There are far more searches, and apparently there is far more public interest, in IQ tests than in psychological testing in general. I wonder why the fascination? Maybe people see IQ as more important than other traits that tests measure. There are several high IQ societies, but no high extroversion societies.
