![]() ![]() However scholar Arthur Jensen has shown that when you measure the mean reaction time repeatedly in college students (each one playing 20 times and taking the average simple reaction time for each student), most of the variability between individuals gets cancelled out and the standard deviation of the averaged out reaction times is only 29.23. Scholar Michael Woodley and his colleagues have argued that the population standard deviation for simple reaction time in Western countries is 160.4 ms, a truly colossal figure. The next thing we need to do is equate the standard deviation for simple reaction time with the standard deviation for IQ. In fact, this is a well known psychometric technique called equipercentile equating, and was used to norm the famous Mega test using SAT scores (see section 8.4.1 of the Prometheus MC Report for more details). Since this self-selection is g loaded, and since both reaction time and a 5 minute IQ test are probably both only moderately g loaded, it seems reasonable to equate them. But what they’re really self-selected for is intellectual interests and the internet access to pursue them. Some might argue that you can’t just equate the two figures because there’s no reason to assume chronometric players will be equally self-selected for reaction time as they are for IQ. Even though Thinkfast customers are not the same as visitors, it’s reasonable to assume that both populations have the same IQ, since they’re both self-selected internet users with an interest in reaction time. ![]() Well we can estimate the average IQ to be 117 because many years ago, a company called Braintainment sold a complex series of reaction time tests called “Thinkfast” and customers on their website had an average IQ of 117 based on a five-minute IQ test. In order to equate that to IQ, we need to know the average IQ of people who take that test. The average reaction time of those who take that test is 253 ms. PART 1: TECHNICAL DETAILS (SKIP TO THE PART 2) For more information, you can compare your results online.Eminent scientist and intelligence blogger Bruce Charlton once blogged about converting reaction times into IQ score equivalents, and now that blogger alcoholicwisdom has told this blog about a really user friendly reaction time test at, it’s time to explore this idea further. It presents an overall score, a graphics score, and a CPU score, allowing you to identify if either your CPU or GPU might be holding you back in terms of 3D rendering. When it's done running the benchmark, 3DMark will present you with an in-depth results screen. If your computer is capable of running it, 3DMark will automatically put it front and center, allowing you to simply click RUN to get the ball rolling. Since we're interested in 3D performance, the free Time Spy benchmark is perfect. If you want to see if your hardware is up to the task of running resource-intensive modern games, this benchmark is what you're looking for.ģDMark comes with a lot of benchmarks, many of which are only available if you pay for the premium version. This benchmark is primarily aimed at gamers, and its individual benchmarks are each designed to simulate games with 3D rendered graphics. A lot of the benchmarks are locked behind a paywall.Ī lot of our favorite benchmarks include 3D elements, but 3DMark is specifically focused on that task and an easy pick for the best 3D benchmark. ![]()
