You need neither MRI machines nor DNA sequencers to detect intelligence. IQ test perform much better at detecting intelligence.
Yes, but that wasn't the point of my post; I was replying to:
Finding things (such as convolutions in brains or genes) that are indicative of potentially valuable talent is the kind of thing that helps make efficient use of it.
An MRI machine was an example of a device that could detect convolutions ins brains; a DNA sequencer was an example of a device that could detect genes. My point generalized to "it doesn't matter how good you are at testing for , if you don't apply the test." If we look at IQ tests instead, then (again) it doesn't matter...
Another month has passed and here is a new rationality quotes thread. The usual rules are:
