Nothing you say or do change the basic facts:
If a doubling from Strength 10 to Strength 20 is enough to increase the CR, it is because the monster makes strength-based attacks, and the resulting attack bonus or damage passes some threshold in the CR calculation.
Conversely, if a doubling of Int should lead to an increase in CR, it needs to be because the creature makes Int-based attacks (say, spells) and the increased save DC passes some internal threshold.
In this way, the Int increase is indistinguishable from, say, a Charisma increase.
Intelligence is *not* a magic number that miraculously makes the monster use different tactics or allies. None of that is in the actual design, numbers and words on paper.
In your reply you completely ignore all the objective fact-based complaints. At this point let me remind you that you can always put forumists you disagree with on your ignore list.

Funny, in an extremely ironic way, that you're accusing me of ignoring "objective facts" when it's "objectively factual" what the DMG says right in the introduction on how a DM should run monsters/NPCs, and you've been completely ignoring those two very important areas in particular.
Here's another "objective fact": The game is not stat block comparisons. It's not just a math problem. It's a role playing game. That means role playing, which does not stop when combat starts. The flavor text, and things like intelligence, are just as, if not more important, than any other statblock unless you're throwing out a huge chuck of what the game is about and only play arena style board game D&D. Which again, is fine if that's what you prefer. But you need to understand how the game is designed and stop insulting and blaming the designers because you decide to ignore a huge chunk of the game.
Intelligence very much impacts the challenge of an encounter because it dictates to you as the DM how you should be running it. It's the difference between two monsters, identical in stats except intelligence from one monsters just lumbering along and engaging in melee combat with the closest PC, and one that lays in wait, ambushes, sets traps, or specifically targets party weaknesses. You seem to be arguing that they are the same challenge since their statblock is the same, and that's just ridiculous. The only way they are the same challenge is if you just compare stat blocks in a white room and totally ignore the actual role playing in a game world. I guarantee you in an actual game, they are completely different levels of challenges to the party.
