The Low-Ball
Get the yes, then change the terms.
What it is
Someone gets you to commit to a great deal, then changes the terms once you’ve said yes. Price goes up. Extras disappear. Conditions appear. Most people still go ahead, because they’ve already made the decision in their head. Robert Cialdini and colleagues showed this in a 1978 study: students who agreed to take part in an experiment, and were only then told it started at 7am, mostly stuck with it, far more than students told about the 7am start up front.
The yes grows its own reasons. You’re already picturing the car, the vacation, the job. Backing out feels like losing something you own.
Why it works
After you commit, your mind starts collecting reasons to like your choice. By the time the terms change, those reasons are still standing, even though the original reason (the great price) has gone. Backing out means admitting you were wrong, or wasting the time. Plenty of people would rather pay.
Spot it
- A deal that seems unusually good at the start.
- New costs or conditions appearing after you’ve said yes, often with an apology or “my manager.”
- Pressure to sign or commit quickly, before the details are on paper.
- Phrases like “One small thing I forgot to mention” or “Oh, that’s standard.”
- You notice you’re paying more than the price that made you say yes, and you’re still going ahead.
Counter it
- Get the terms in writing before you commit. Price, extras, conditions, dates. In a text or email if nothing else.
- Ask the “anything else” question. “Is this the full price? Is there anything else I’ll need to pay or agree to?” Ask it twice.
- When the terms change, re-decide from scratch. Ask yourself: “If they’d offered me this from the start, would I have said yes?” If not, say no now.
- Say it out loud. “That’s not what we agreed. I said yes to $550/€550 bills included. I’ll stick to that, or I’m out.”
- Remember the sunk cost isn’t a reason. The hour of paperwork is gone either way. Don’t spend $1,200/€1,200 to make that hour “worth it.”
- Be willing to walk. Low-ballers rely on you being too committed to leave. The moment you’re clearly willing to walk, the original deal often comes back.
Useful lines:
- “I agreed to the deal you offered. If it’s changed, I need to think again.”
- “Let’s go back to what we agreed.”
- “I’ll need that in writing before I sign anything.”
