Totally agree on your example:

> One day you dig into it and realize I just hard-coded "not today" [0] which is 99.999% accurate.

It only becomes visible when you do the research.

The justice process in this example just has to check and verify the inputs. There is no way around it. Today it is this expert, tomorrow another one.

When someone is caught that's an ethical issue and there could be more structural consequences as well. Like blocking the person as an expert or other means. As the expert becomes untrustworthy.
