Lifeguards scan the whole pool in a pattern, not just the loud end. Lead the same way.

Trouble is rarely where the noise is. Whatever is loudest takes your attention automatically, which means the quiet corner, the person who stopped talking, the task nobody has mentioned in a fortnight can go unseen for weeks. A pattern beats instinct precisely because it looks at the places instinct skips.

Build a sweep into your week instead of waiting to be alerted. Check in with every person in a fixed order, including the ones who never ask for anything. Two minutes each is enough to catch what the loud end hides.
