Scans might be easier to sell to parents when putting the child in a different educational path than an IQ test. IQ tests may be perceived as just an individual rating the child, and parents that aren&#x27;t completely happy with a result will get in the mindset that the tester &quot;rated the child wrong&quot; or &quot;didn&#x27;t measure the right things.&quot; An actual brain scan may be harder to argue and more effective in the end from the parents&#x27; point of view.
