Why Do the Small Problems Still Slip Past Us?

You've trained your eyes on the big mistakes, and you catch them now. Good. But the subtle ones still get through — the wrong assumption, the quiet gap, the thing nobody flagged because it looked almost right. This is not bad luck. It is what happens when a team gets good at one kind of checking and stops looking for another. Competence breeds a kind of blindness. You trust your own judgment because it has been right before. Your team trusts each other for the same reason. That trust is earned, but it closes the door you most need open — the one marked 'what if we're wrong and don't know it.' You cannot fix this by trying harder at what you already do. You fix it by building doubt into the process itself — a moment where someone must ask what the group assumed and never tested. That is work. Choose to do it anyway.
