Eight Criteria For Identifying An Intelligence
An ability qualifies as a distinct intelligence only if it meets signs like potential isolation by brain damage, the existence of savants and prodigies, an identifiable core operation, a distinct developmental trajectory, evolutionary plausibility, support from psychometric tasks, support from experimental psychology, and encodability in a symbol system. This converts the question 'what counts as intelligence?' from intuition into a checklist where candidates are tested against biological, developmental, and cultural evidence.
