"performance" is an undefined vague attribute.

Define what they are performing at, and what you say becomes true, but then who is a high performer changes with every task.

For example, consider the police stations with maximum allowable IQs to be hired. The people in charge of the stations noticed that people with a high IQ were low performers, at that job. NASA meanwhile has no such cutoff.

IQ isn't anywhere close to being a performance metric.

		Right, exactly, nothing is, because "performance" is a meaningless term without context. Unless you're saying that there exists no conceivable context in which IQ would be a performance metric, in which case you would be wrong.
