I thought I was finished with this topic. Then I saw a rather credulous interview in BusinessWeek.com with a CEO about his company's online personality test. According to the interviewee, "enlightened employers consider personality as only one facet of the selection process." This CEO was touting his online personality test as one of the selection criteria. If you follow the links far enough you can take the test. I did, and got a report that had a little more information than an average horoscope. To get the detailed report you need to pay.
The website turns out to be a social networking site where people can meet others of similar "temperaments." Good grief. I sincerely hope no one in an HR department would be foolish enough to adopt this thing as a selection criterion. I've written about personality testing before, and this does nothing to change my opinion.
I think Scott Adams was on the mark with his send up of personality testing in companies.
