Shouldn’t there just be around 1 in 1000 experiments the state reach 3 sigma for a result which then turn out to be noise?
I guess that only applies if there are no mistakes or biases at all?

You're not seeing all the searches that didn't pan out.

Yes. I think it's a joke.
As in 3-sigma ~= 1/1000

Yes but he brings up a good point. They are more likely to talk about a 3 sigma result that challenges the standard model than one that doesn’t yield anything special. So given you know a 3 sigma result is being discussed, the probability that it’s a false result at higher sigma is more than 1/1000.
This is not a bad thing, by the way - just an inevitable consequence of doing many searches.
