I'm not sure I've ever heard it put that way.
We were kind of talking about the gut reaction test, and certainly if you have that kind of gut reaction, that might be reason to pause. That's not necessarily reason to definitively remove yourself from an entire conversation, because it might be that the conflict isn't what it seems or it might be that once the conflict is disclosed, the relevant decision-makers might still want you to be part of the decision-making because of your perspective or insight or expertise.
Certainly, yes, we want to say that people should have enough of a sense of what these issues mean that if it smells like it might be a conflict of interest, their initial reaction should be to put on the brakes, take a step back, talk to the relevant parties and then figure out whether you can go forward.
