Law 21 of 48

Seem Dumber Than Your Mark.

Appear less intelligent or knowledgeable than your target. By appearing less intelligent, you can disarm suspicion and encourage your mark to underestimate you. This tactic can give you an advantage in negotiations or strategic interactions.

Independent commentary on a principle popularised in The 48 Laws of Power by Robert Greene and Joost Elffers. Not affiliated with or endorsed by the authors or their publishers.

What it actually means

Showing how much you know buys a moment of credit and costs far more in what people stop telling you. Asking the obvious question is not humiliating; it is the cheapest way to find out what someone actually believes. Being underestimated is an information advantage, not a disguise.

Where you would have seen it

In a supplier meeting you correct their pricing model to prove you have done the reading. They tighten up and stop explaining, and you leave without the one thing you came for: which line item they are desperate to keep.
