Fogging

Calmly agree with any grain of truth in a criticism without caving or counterattacking.

Why it works

Manipulative or hostile criticism works by provoking either a defensive denial or a counterattack, both of which escalate. Fogging defuses it by calmly acknowledging whatever small truth the criticism contains ("You may be right that I was late") while conceding nothing further. With no fight to feed it, the criticism loses momentum and the critic can’t escalate.

How to do it

1. Find the kernel of truth or possibility in the criticism, however small.
2. Acknowledge it calmly ("You could be right", "That’s true, I did…") without apologizing or arguing.
3. Stop there — don’t add justification, defense, or a counterattack.

Evidence

Fogging is a named assertiveness technique with roots in behavior-therapy assertiveness training, taught specifically for handling manipulative or repeated criticism calmly. The term and method were introduced in Smith’s (1975) systematic assertive-therapy program, and Speed, Goldstein, & Goldfried’s (2018) review frames the broader assertiveness-training tradition it belongs to as evidence-based. (clinical)

An established clinical/training technique; the standalone outcome research is limited, and fogging is for deflecting hostile or manipulative criticism, not for dismissing fair, useful feedback.

Common mistake

Using fogging on legitimate feedback to avoid actually engaging with it — the technique is for manipulation and hostility, not a way to wave off valid criticism.
