I really like the idea but it's completely off. What it should do is measure your reaction time: the time between the sign appearing on screen and the user pressing the mouse or tapping the screen. What it does is include frame rendering time. I apparently have the reaction speed of a 80-year-old at 22 (900ms), while I'm sure my reaction time on computers is around 225ms (measured on different occasions). Also, you c…

This. There's a reason many reactiontime experiments in e.g. neuroscience use a photo sensor on the screen to figure out when exactly the stimulus comes, and then compare that with reactions like keypresses by sampling both signals on the same AD card.

I wonder if something which flatters the user is more likely to go viral? That it consistently underestimates my age by a couple of decades certainly makes me want to link to it and boast.

Not sure if I'm flattered by the fact that it said it wasn't sure whether I was human 10 times in a row :(

I may be off here but, I found that when I had the window fullscreen the graphics were rendering very slowly and my reaction times were very slow. I then made the window smaller and the graphics were much smoother time and my reaction times were much better.

Same here. I reduced my reaction time from 500ms to sub-300 after re-sizing the window down to about 400 by 400 px. If anything, their model suffers from omitted variable bias--the power of your computer!

Me too -- after reading your comment, I found that I effectively halved my age in a dozen trials or so with a smaller window.

Interesting, I get a decade younger with each try... Doubt there is much behind the conversion between reaction time and age, but it's a nice setting to test your reaction time :-)

I managed to get 283 milliseconds, which is off their chart. It speculated I wasn't a human.

I was 57 the first time though.
