Hello smart folks! I am developing an IQ test and is currently bringing all the tasks together, for one complete test. There will be no time limit on the test and it will be "culture fair", i.e. un-biased in terms of education, cultural upbringing etcetera. I am going to organize the tasks in three levels: novice (1), difficult (2) and advanced (3). I am not quite sure yet how to divide the tasks and would therefore like to investigate this further with your help. I think that probably ten to fifteen volunteers would suffice. I have put up one of the tasks on the web and would like you to take a look at the task and replace the question mark with your own answer to complete the set. I will then use the 10-15 first answers to appreciate the appropriate levels of difficulty for the tasks. I can reveal that a friend of mine actually guessed his way to the correct answer for this task, but without adequate reasoning behind his choice. Probably due to the fact that there are only some few figures that are likely to fall in the question marks place, but in fact there is of course only one correct answer. Send your reasoning behind your choice of answer to me at petersmith.de (gmail), or send me a PM here on the forum. If too many succeed to solve the task, I will probably have to revise the test. But don't hold back. ;-) http://www.flickr.com/photos/33083694@N08/3080228094/ [Broken] I appreciate your help. /Peter S.
