If you have low sneak you need to stay still, run away find a corner to hide in sneak and stay still.
The game describes it to not see you, thats it. your not manipulating there mind to forget you are there just to not see you.
would you seriously stop looking for someone just because you can't see them anymore? as I said before it's an improvement to the AI.
honestly your starting to sound like a troll to me, if you want to go by illogical, why is it when I catch someone on fire they still attack me and completely ignore that there on fire. Or how my horse fights by my side and doesn't run away. or how you can stick a kettle on someones head and steal right from under there nose. Or for that matter why is there magic at all. Because MAGIC IS ILLOGICAL.
Yes, I would SERIOUSLY stop attacking someone who vanished before my eyes. I would retreat to a defensible position and defend it. Back into a corner, swinging my blade in front of me or covering my head and face with a shield. I wouldn't chase the person, because he has the advantage. He's INVISIBLE. In hand to hand combat, there is NO WAY that being invisible ISN'T, so great an advantage, that you wouldn't immediately stop attacking and start defending. Or, you would die. If you could hear him running away, you would let him go, and count yourself lucky.
Sure you MIGHT get lucky swinging wildly and hit him, after moving toward the sound of his footsteps...but seriously...you would most likely just die, if you tried. The first wild swing would get blocked or parried or just dodged because you didn't know exactly where to strike, and then you'd be stabbed...because you couldn't see where the counter-attack was coming from. He's INVISIBLE. And you would be aware of this, and NOT chase him. When it's your life, "might" isn't good enough.

These aren't boss mobs I'm talking about...these are common grunt/thugs that you run into everywhere in the game. They would die, to even a really stupid invisible foe. And they would have to be really stupid themselves not to immediately, intuitively, understand that. And if they are that stupid...you should be able to kill them in one hit, because that is logical

But it's not just that, that is illogical. Automatons shouldn't be affected at all if, as the description says, invisibility is mental in nature. They have no brains to control.
I didnt expect to spend 10 posts saying "...yes...no really...it's stupid". I thought it was so obvious, that no one would disagree. I just wanted opinions on Bethesda's motivation, and if anyone thought it was intentional, or unintentional. Not insist that it didn't exist.
Maybe I should have more clearly stated that. I don't know. My bad.
