Logic test. It is difficult enough. A test group of 2000 members gave on average 3.04 right answers (from 10 available). This test doesn measure intelligence quotient itself, as this quotient still is not uniformly defined. It shows you difficult logic problems instead and counts the number of your right answers, so after taking the test you can compare your results with the results of other participants. Actually questions are more complicated than in usual iq tests. You can find answers to the problems, and to the problems from the world\'s most difficult IQ tests at the project\'s forum, located at http://wordofmouthexperiment.com/forum/viewforum.php?f=27 . Also you can discuss other intelligence and IQ related topics there.
