How well would your IQ score reflect your actual intelligence if you were to take an IQ test in a language you have trouble understanding and expressing yourself with?

It's well agreed that multiple factors contribute to IQ score. What I'm trying to convey is how much burden is predicted by the autism diagnosis.

You're yet to establish the link between IQ score and " burden.

That said, valuing people by their economic output is sick to me, and is a page from the Eugenicists playbook. How much of a "burden" are injured veterans, those who suffered horrific work-place accidents, or those with mental health challenges due to burn out?
