While I agree with the thread here in many ways, I will answer In true autistic forum post format.

Can you pick up any book, read it, and understand the gist with minimal repetition?

I've never had to re-read a book to 'get the gist', but I will sometimes if it's interesting (though nowadays it's technical documents, and just to get the wording of how someone else said it exactly as they said). Podcasts and other stuff more commonly I will re-listen/watch, but that's often because audio is less grok-able than text with inflection and other stuff.

Can you infer solid and accurate conclusions based on a small amount of evidence?

This one most people can actually do, it just depends on their experience where and how often they can do this. You can also tell someone has little in touch with reality if they are vocal about stuff all the time and are hilariously wrong consistently, yet still do it.

Is any subject or discipline up for grabs or do you have to have a keen interest in a particular field in order to flourish?

I suppose it could be, but optimizing your talents isn't just 'what are you good at' but also 'what can I get good at with this, quickly'. Doing that has made me a lot happier in life overall, not just professionally.

What is something you are able to do that you know is because of your intelligence -- the proverbial 1,000 pound deadlift of the brain, if you will.

This one I don't actually know, or maybe it's just being this way? Not sure... If I had to take a stab at it, actually explaining the difference between the Abrahamic religions, including the gnosticicm offshoot that we are currently living in the hellscape of.
