The idea
More sophisticated explanations of other people's behavior are not necessarily more accurate. Useful reasoning moves between simple and strategic models as the evidence warrants; another observation may distinguish them better than another layer of speculation.
Worked example · illustrative
Is there really another buyer?
Situation. You’re looking at a secondhand car and make an offer below the asking price. The seller says someone else is coming to see it tomorrow. You wonder whether they’re trying to get you to pay more.
The tempting conclusion. They’re bluffing. I’ll hold my offer and wait for them to come back.
What changes the view. Another viewing is quite possible. The seller could also be using it to put pressure on you—or both could be true. Asking whether they’d accept your offer today gives you something more to go on, though their answer won’t prove whether another buyer exists. If they later come back with a lower price, that changes what you can negotiate, even if you still don’t know why.
What this supports. You can take the possibility of another buyer seriously without raising your offer just because the seller mentions one. What you’re willing to pay, and whether you’d be happy to keep looking, still matter. Their next response may help you judge how much room there is to bargain; you don’t need to be certain they’re bluffing to decide what to offer.
Useful when
Watch for
Neither simplicity nor sophistication proves an explanation correct. Avoid assuming hidden motives without evidence, but do not dismiss strategic behavior when observations support it.
