Persuasion knowledge model
When we sense we're being sold to, our guard goes up.
What it means
A model describing how people develop and deploy beliefs about persuasion attempts — recognizing tactics, inferring motives, and coping accordingly. When a persuasion attempt is detected, this 'persuasion knowledge' is activated and people adjust their responses, often by discounting the message, the messenger, or both, in a 'change of meaning.' Persuasion knowledge grows with age and experience, which is why obvious sales tactics lose force over time and why marketers seek subtler, less detectable approaches. It matters as the consumer-side counterweight to influence: the more transparent the manipulation, the more it can backfire.
Examples
Recognizing an influencer's glowing review as a paid promotion, viewers mentally deduct credibility from it.
A caller who opens with 'this isn't a sales call' convinces the listener it is exactly that, and the rest is heard as a hunt for the catch rather than an offer.
A magazine feature reads like reporting until the small 'sponsored' label surfaces; readers who spot it reread the whole piece as advertising and quietly discount every claim in it.
First described in Friestad & Wright (1994).
