Yes Popper focuses on error correction.
People are fallible and can miss things. You can try talking to people outside the room. But (oversimplifying) there’s no way to protect against errors no one is able to figure out. No rival epistemology does that either.
That gets into details of how to have effective critical discussion. I have some relevant writing like Intuition and Rational Debate
I think error correction instead of induction is fundamental.
