For example, when I see the CGI of a movie, I can almost always tell whether it’s CGI or not
But when it comes to hearing sound effects, it’s a different story
While I’ve never heard of the sound effects of an IRL instance of this example, I was shocked to find out that the sound effect of someone’s bones being broken in violent movies/games is actually just the sound of a guy ripping apart a cabbage

Humans are visual creatures. Far more of our brain is devoted to processing visual input compared to auditory input. Also, visual images are persistent, while sounds are fleeting. That fake CGI alien stays on the screen for minutes and you can keep staring at it, while an individual sound effect only plays for a fraction of a second, so there’s a lot less time for your brain to notice if it doesn’t feel real.

I doubt that. You can tell what is “bad” CGI but if it is good enough it looks real and you do not notice it. The problem is that you never know when the CGI fooled you. It is not the case that after the move there is a breakdown that shows what was CGI or not.
How do you know that good CGI fooled you by just looking at a movie? It is definitionally impossible because if you knew it was CGI it did not fool you.
It is like saying “All toupées look fake; I’ve never seen one that I couldn’t tell was fake.” the problem is the same if you could not tell that it was fake you do not know that it was a toupée and not just hair.
Take a quiz like [https://fakeorfoto.autodesk.com/](https://fakeorfoto.autodesk.com/) and see if you can tell CGI or reality apart.
Still, images are simpler to fake than moving images but look for “CGI breakdown” on Youtube and you can see good CGI that you never notice. If it is not human faces you are really bad in telling CGI and reality apart.
You clearly know that something likely is CGI because things like that do not happen in reality but you miss things like background, cars, and other things that exist in reality but are faked in movies. You will know that when Spiderman swings around in New York he is likely CGI today but you miss that all the buildings are CGI
Or it is like in [https://youtu.be/6d8p-ls4MIg?t=89](https://youtu.be/6d8p-ls4MIg?t=89) where Spiderman and MJ are real but the city behind them is CGI
The type of audio effect that is simplest to spot as fake is the same as for visual effect. That is human speech and human faces.
You can spot bad CGI and know that something you see likely is CGI today because it is thing that does not exist in reality or does not happen in reality. CGI of stuff that does exist in reality is very hard if not impossible to tell apart from something that is real.
Sound has the advantage that there is no sound that you know cant occur in reality. There is no audio equivalent to an alien spaceship hovering over a city.
1. because its much easier to get realistic sound than realistic graphics as most sounds are recorded from real life.
2. because you usually don’t hear the sounds in movies in your daily life, so if they are a bit off you won’t know.
if you, for example, listen to all kinds of explosions daily then watch a movie with mismatched/slightly off explosion sounds you might be able to pick up on it.
