This map of the United States appeared in my Twitter feed today. The poster of the picture @zoo_quiz promised that if you answered 30 questions they could predict what state you live in. I took the test and was surprised at the results: I live in New Jersey! WRONG!! Not only do I not currently live in New Jersey, I have never lived there. The states I have liven in are: Illinois, Iowa, West Virginia and Maryland. How their tool chose New Jersey for me is a complete mystery. So, this is a reminder to all us not to take test results too seriously unless we know the accuracy of how the test is scored and/or administered.
