I don’t follow your logic. “The gifted person is highly intelligent, just not good at deadlifting 500kg” does not diminish the 500kg deadlift and I wouldn’t expect an IQ test to measure it.
I think the key here is to be wary of measurements that promise to capture the whole of what we consider intelligence (ie what people think of with IQs).
Not being able to deadlift 500kg also signifies the inability to effectively the (physical) environment.
But even here, in your irrelevant example, you are wrong. In practice IQ is highly correlated with emotional skills ("intelligence").
And as we said, the "IQ tests" do not promise that.
> what people think
What people think is very irrelevant to truth - and we just disregard their opinion. It cannot have a weight.
What would be the gain in asking a layman about anything. It just makes no sense.
