First, I posit that with writing tools anyone will accomplish more and faster than you could with only your mind.
Second, Since the first premise is true, then I say you are smarter when equipped in that way than when you are not.
Maybe yall are getting hung up on the IQ aspect of this question. IQ is about innate ability. Once you add something to that, then it is no longer IQ. It is something else. That’s fine. You want to get down to brass tacks, that’s fine.
But, if some tool, given to an IQ test taker would boost their score, then the amount of that boost is how much that tool added to the users IQ.
So, How much do tools add to the normal mans intelligence regularly?
