If models can control their chain of thought and recognize that it is monitored, they may deliberately conceal bad thoughts from their monitors.

“this this is a problem because like if you you could have a situation where the model understands what it's what chain of thought is and and that people are observing it and eventually they will because like this is all in the pre-training data right like you know they the idea of chain of thought monitoring has been around long enough that like it's in the pre-training data they're aware of it um but that they're not actually able to control their chains of thought if if we reach a point where they're actually able to you”

“recognize like oh i am being observed i want to think these bad thoughts in a way that is not observable to my monitors and then they're able to actually do that then then there's then there's a problem and then we have to rely on other methods for observability”
