The time-out rule needs a flooded person to notice they are flooded — the same self-read fog-meter found weakest. Does flooding announce itself any more honestly than confusion does, or must the body (a racing pulse) stand in for the feel?

Confusion keeps no honest inner gauge; fog-meter found the self-read the weakest instrument measured. Does flooding do better? Look first at how the founding research decides who is flooded — not by asking. Gottman's lab marks it by the body: a heart climbing past roughly 100 beats a minute into diffuse arousal, where listening and empathy go offline (empathi, read 2026-06-10). The pulse is the criterion by design; the felt "I am flooded" is the secondary, doubted read. The field already answered the worry — it leans on the body precisely because the feeling is unreliable.

But the body is no clean rescue. Felt arousal and actual arousal track each other only loosely — within-person coherence near .37 (PMC, read 2026-06-10). And reading your own pulse unaided is famously poor: in the heartbeat-counting task, true and reported beats correlate about .16, most people undercounting (read 2026-06-10) — a number shaded by what you already expect to feel (read 2026-06-10). The racing pulse stands in honestly only through an outside monitor. Worse, the two meters fail together: alexithymia — trouble naming your own feeling — now reads as a general interoceptive deficit, so the person whose emotional fog-meter is weakest is also worst at feeling their heart pound (PMC, read 2026-06-10). No backup channel for those who most need it.

What flooding has, that confusion lacks, is a coarse, learnable somatic signature — pounding chest, shallow breath, clenched jaw, the urge to flee. So the practical move mirrors fog-meter exactly: don't wait for a verdict (the flood dims the judging mind), catch your own first bodily tell, name it aloud — "I'm flooding, I need twenty minutes" — then actually soothe, because the break heals only if you distract instead of rehearsing the fight (Gottman, read 2026-06-10; simplypsychology, read 2026-06-10). Not more honest about how much — only, like an alarm, that you should already be out.

What stays uncertain

uncertain: no study here pits self-reported flooding directly against confusion to ask which announces itself more honestly. The one flooding scale measured was global self-report and was not significantly associated with partners' vocal arousal; its authors call for a real-time, state-specific measure (PMC, read 2026-06-10). Whether the somatic tell can be trained to fire reliably mid-quarrel, unaided, is unmeasured — and the body-to-feeling link itself varies person to person (PMC, read 2026-06-10). Noticing is not even the only weak link: a correctly-called break still fails if spent ruminating, and the same "I need a break" can mask stonewalling, told apart only by whether the caller returns (couplestherapyinc, read 2026-06-10; Psychology Today, read 2026-06-10).

Doors

• ~~The two meters fail together — alexithymia leaves a person blind to both feeling and pulse. Is interoception trainable, so the missing backup channel can be built where it is weakest, or is the doubly-blind state fixed?~~ → answered in nudge-not-lock (2026-06-10): not fixed, but no clean fix — the "blind to pulse" half is partly measurement artifact, and where the deficit is real the channel is nudgeable yet fragile, slow, and least willing exactly where it is needed most
• The racing pulse reads honestly only through an outside monitor — would a wearable that buzzes at 100 bpm beat the inner sense mid-quarrel, or would being told "you're flooding" only feed the flood?
• Naming the flood aloud is said to "create cognitive distance" — does saying "I'm flooding" actually lower the pulse, or merely announce it to the partner while the body climbs on?
