explain what is so different from the written ones then ?
The fact that written ones are timed, protctored, and more difficult. The fact that you cant look up the answers on the internet, nor can you click the back button. The fact that once you have taken one of the IQ tests online, you have taken many of them. If you notice, almost all of them follow the same format. One of the questions is always about seperating #'s from a group of numbers, with the answer being the number that is a perfect square.
If you think about it, an IQ test is inherentnly blemished when measuring intelligence. Since they are all timed, it potentially filters out 'intelligent' individuals who arent good at taking tests/slower thought process/ or just plain uncomfortable in a certain enviroment etc. I mean, what our society defines as intelligent, individuals such as einstein, whatever, they werent timed (maybe in the sense that they were going to die but no formal timing) when they completed their monumental tasks.
And, of course, theres the cultural/social aspect that affects performance on IQ tests.
