You can view the test as a very entertaining IQ test from hell. The questions seem often simple. But, they are not. Other times, they are obviously difficult. I got a bit more than half of them correct. This was mainly because I had some knowledge or experience regarding certain traps the questions presented. I had made the mistake before. So, I learned from that. When I did not have any prior knowledge of a question, my results were very human, meaning not that good. But, learning the correct answer was both fun and educating.
The author touches on several fascinating probability and statistic concepts. One of them being the Bayes theorem, which suggests that medical screen test can be highly unreliable despite being touted as 80% to 90% accurate. In other words, you better understand the Bayes theorem better than the medical specialists who screen you for various diseases. Because, based on the author's study, doctors don't have a clue. Another chapter had an excellent discussion on correlation vs. causation. This includes some tricky nuances that many analysts in the financial industry trip upon. Another interesting probability concept is why it takes only 23 people in a room to have greater than a 50% that two of them share the same birthday. This seems impossible, but it is true.
The book has obviously a lot more than I am letting on here. I am not going to ruin it for you. It is really fun, educating, and interesting to read. You will also learn a whole lot about how you think, how others think, and how people think in groups. You will also understand how tricky it is to ask truly open and objective questions. Also, polls that seem objective are not due to the subjective structure of the question. I think you will enjoy this book, and I strongly recommend it.
