Fun Fact:
The level of collective human intelligence is steadily increasing, so IQ test have to be made harder every few years to keep the average at 100.
Wait wut? I thought whatever the average is was 100, It doesn't matter how hard it is. If everybody got 100% on the test in 20min, then 100% in 20min would be 100 iq.
And yes, online iq tests are inacurrate, but some can give a general ballpark figure. If a test has any trivia on it, close it immediately. An iq test should not measure your knowledge at all. (outside of basic function like numbers, shapes)
I had to take an IQ test for our college fitness course and I scored 156.
edit:
Generally, you wont miss any or very few problems on a real IQ test. It isn't testing whether you get a problem right or wrong, but how fast you arrive at the answer. If you were wrong, it doesn't show anything since you were on the wrong thinking path on the problem. When you get it right it just shows how long it took for you to get an answer.
I heard someone talk about how SAT is a better test of intelligence. The SAT is like an IQ test, but the only thing different is that the SAT doesn't test intelligence. It tests knowledge. Almost all the problems in the SAT are really easy as long as you know the concept behind the problem. If you understand the vocab, the answer to the questions are easy. If you understand how to read graphs in the math section, the graphical questions are easy.
The IQ test is measuring your ability to process information, which is why the questions used generally consist of numbers, colors, shapes, etc...
And about the people who don't believe people scoring as high as Einstein. Your probably right that they aren't, but remember that intelligence is only one aspect of what makes you "smart". You also need to have knowledge in what you are studying/working with, and an understanding of that knowledge. Someone could easily be as intelligent as Einstein, but they use their intelligence to just solve everyday problems around the house and play video games.
