Anchoring
Why is the first number said out loud so hard to argue with afterwards?
The idea
The first salient number can influence later judgments.
In the real world
An opening price changes how a later offer feels.
Going deeper
An anchor works by supplying the reference point against which everything after it is judged, and it operates even when the number is transparently arbitrary. Once £90,000 has been said, £62,000 is experienced as a large concession rather than as a 55% overrun on a £40,000 budget.
The defence is to fix your own reference before the conversation. A written walk-away figure and a written target, decided from your own analysis, give you something to measure against that the other side did not supply. Without that, you are measuring success by distance travelled from their opening, which is a number they chose.
Where it stops applying
Anchoring high can backfire where it damages credibility or ends the conversation. An anchor that reads as unserious loses the negotiation rather than framing it.
Why it matters
It tells you that the order of a negotiation matters as much as the arguments in it.

Test yourself
A supplier opens at £90,000. You had budgeted £40,000 and settle at £62,000, feeling you negotiated well. Against what were you measuring success?
Show the answer
Their opening figure, not your budget. The first number became the reference point for every later judgement, so a result well above what you planned to spend still felt like a win.
