I cross-posted this from another thread to prevent further derail.

Common sense and math. There is an absolute limit to how much variance a game can have, and this correlates positively with the stack sizes. Smaller and smaller stacks definitely don't lead to higher and higher variance. For a silly example, a .2BB stack game obviously has lower variance than a 200BB stack game. How can a shorter game be lower variance when there is literally a limit to the amount of "variance" you can experience in an individual hand? In a 200BB game compared to a 100BB game, you are still winning/losing 100BB hands about as often as you are winning/losing them in a 100BB game, you are just not all-in and have the potential to win/lose even more, which leads to higher variance. There are a lot of times where the stack size limits your win or loss in a game, which directly limits your variance.
There are times where someone might just take a 50BB loss in a 200BB max game where they might commit a stack instead in a 100BB max game, but I don't think this is enough to counteract other effects.

This shouldn't even be a tough question, your variance is so, so much higher in smaller games.
I'd love to look at such a database, but I don't know where they exist. My own online database isn't very big and has hardly any short-stacked hands.
Also, we're talking about short vs. deep games, not big vs. small games. I definitely agree that variance is higher in smaller games in terms of BBs.
Mathematically and logically it makes no sense to me that shorter games would have higher variance.
