Anchoring and First Offers

Anchoring is one of the most powerful and well-documented cognitive biases. The first number put on the table disproportionately influences the final outcome — even when it's arbitrary.

In a famous experiment, Kahneman and Tversky spun a wheel of fortune rigged to land on either 10 or 65, then asked participants to estimate the percentage of African countries in the United Nations. Those who saw 65 guessed significantly higher than those who saw 10 — even though a random wheel has nothing to do with UN membership.

In negotiation, the anchor is typically the first offer. Research consistently shows that final agreements are strongly correlated with the first number on the table.

Should You Go First?

This is one of the most debated questions in negotiation. The evidence suggests:

Go first when:

• You have good information about the ZOPA
• You want to frame the negotiation range
• The other party is less prepared

Let them go first when:

• You have very little information about what they'll accept
• There's a chance they'll offer more than you expected
• You suspect they're overvaluing what you're offering

How to Set an Effective Anchor

1. Be ambitious but justifiable. An extreme anchor that you can't explain will damage your credibility.
2. Use precise numbers. $5,150 feels more researched than $5,000 and results in less aggressive counter-offers.
3. Anchor with ranges. "Comparable roles pay $90,000 to $110,000" sets a high anchor while appearing reasonable.

Worked Example: Anchoring a Salary

Devon is interviewing for a role. Market data (level guides, Glassdoor, a recruiter friend) says comparable roles pay $95,000–$115,000. The recruiter asks for his expectations.

Weak move: "I'm looking for around $100,000." This anchors near the bottom third of the range and quietly caps the outcome.

Strong move: "Based on comparable roles and my experience, I'm targeting $118,000, though the whole package matters to me." The precise, slightly-above-market number, justified by data, pulls the range upward. Even if they counter at $108,000, Devon lands higher than his $100,000 opener would have allowed.

Two rules do most of the work: (1) anchor first only when you actually know the range; (2) make the anchor ambitious but justifiable — an unexplainable extreme number destroys credibility instead of moving the range.
