Fogging technique: agreeing without caving

The fogging technique: calmly agree with whatever grain of truth a hostile criticism contains, concede nothing further, and add no defense.

Why it works

Hostile or manipulative criticism is not really a request for a correction — it is an attempt to start an exchange, and it needs your resistance to continue. Both instinctive replies supply that resistance: denial gives the critic something to push against and prove, while a counterattack converts it into a fight where the original criticism no longer has to stand on its own. Fogging removes the fuel by giving the critic literally nothing to argue with. You calmly grant the small true part ("You may be right that I was late") and stop — which is not agreement with the verdict, only with the fact. Because you have neither denied anything nor attacked, there is no opening to escalate into, and the criticism has to carry itself. It is named for what it feels like to push against: a fog bank absorbs a blow rather than resisting it, and offers no surface to strike.

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.

Be precise about what is supported here: fogging is an established teaching technique from the assertiveness-training tradition, and that tradition as a whole has an evidence base — but fogging itself has not been trialed as a standalone intervention, so treat it as a practitioner method with a credible lineage rather than a separately proven one. It is also scoped: 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.
