From cradle (or even before) to grave we are subjected to tests, some more intrusive than others. Krogerus and Tschäppeler have gathered together the (physically) less-intrusive tests, some famous, some more obscure, some which are long standing and others which are only recently developed as tools to help us understand our lives - our strengths and weaknesses and how we are using them. All the tests relate to YOU, the reader and for the most part they're fun and quick to do. I read the book straight through, but you could equally well just dip in and out and test yourself, or encourage other people to do the same.
So, what did I investigate and what did I learn? I ''knew'' that I drank drink slightly more than is good for me (in so far as I am within the permitted units of alcohol per week, but without the number of alcohol-free days which are preferred) but I had the same result - 'problematic consumption' as someone who drinks ten units a day, every day. I guess I wanted to feel good about being only a little bit bad... Fortunately I am not depressed - in fact I'm self confident - and I know how to respond to questions in an ink-blot test. I was a little surprised to find that I ''am'' clever, but a closer study of the test made me wonder if it wasn't that I was ''clever'' but that I was ingenious and rather drafty. I've discovered that I'm rich.
I know where I stand politically - although the graph differentiates between Liberal/Conservative on the vertical axis and Left and Right on the vertical. What I would have appreciated knowing is how to vote when you realise that the politicians involved seem to be a set of numpties whom you wouldn't trust to run the tea club raffle, much less the country - but then that might be beyond the scope of such a slim book. Most fascinating for me was the Turing Test, whereby you can establish if you are talking to a robot. It explained a lot.
