Split the Difference Trap

What it is

Proposing to "meet in the middle" after anchoring at an extreme position, so the "middle" actually favors you significantly.

How it works

You anchor at an extreme position. The other party anchors at a reasonable one. "Let's split the difference" sounds fair but actually gives you most of what you wanted, because the midpoint between extreme and reasonable is still extreme-leaning. The appeal to fairness ("meeting halfway") disguises the unfairness of the midpoint.

Real-world examples

  • •A contractor quotes $50,000 for a $25,000 job. You say $25,000. "Let's split the difference at $37,500" — still $12,500 over fair value.
  • •Salary negotiations where one side anchors unreasonably high, then "compromises" to still-unreasonable.
  • •Diplomatic negotiations where one side makes extreme demands to shift the eventual compromise point.

Ethical guidelines

  • ●Splitting the difference is only fair when both starting positions are reasonable.
  • ●If one party deliberately anchors at an extreme, the midpoint is not a fair outcome.
  • ●"Meeting halfway" has moral weight only when both halves represent genuine positions.

How to defend against it

  • ►Never split the difference with an unreasonable anchor — insist on objective criteria for fair value.
  • ►When someone suggests meeting in the middle, evaluate the midpoint on its own merits, not relative to positions.
  • ►Anchor your own position based on evidence and be prepared to justify it independently.
