I suppose the test measures the ability to differentiate details among items. I can see how this would be a sign of intelligence. If two people cannot understand how two things are different, then they cannot learn. Learning is about assimilating new information, but if the person doesn't believe or see that there is new information there, then no new neurons will be formed to store the new information.

This was Francis Galton's theory of intelligence more than a century ago, but repeated studies have shown that sensory discrimination is very poorly correlated with anything that can properly be called "intelligence" among adult test-takers.
Interesting. Wouldn't this also reduce the validity of this 5 minute IQ test?
I suppose there could be physical issues, like poor vision or tactile sensitivity that would affect a test like this. So I wonder, perhaps people who can see better are more likely to be smarter simply because they can observe more items in the world.
