I wasted money on this book as preparation for the Mensa IQ test.
Why wasted? Because many of the questions are general knowledge, not tests of IQ. IQ tests are designed to test reasoning, not knowledge.
So how can the authors justify questions like the following?
- What is the name given to a group of arrows? (test of vocabulary, not reasoning)
- Find six birds? (hidden in a matrix of letters - only an ornithologist would recognise some of the birds in the solution)
even more obscure is this one on page69:
Place these items in three sets of three (fish, trees, drinks)
BLOATER ANISEED CURACAO KOUMISS REDWOOD POLLOCK POLYPUS DOGWOOD PERRIER
(the experts may know that koumiss is a drink and polypus is a fish, but I didn't).
The botanists might also like "Prunus domestica is to plum as Vitus vinifiera is to:"
cherry, prune, pomegranate, peach, grape (it's grape, perhaps the "vin" gave a clue).
It is hard to believe that one of the authors is an "IQ test expert" as mentioned on the book's cover.
So in short, this book did not help me to prepare for the Mensa IQ test at all.
Luckily I still passed.
