The research, plainly
Tversky and Kahneman showed that even obviously arbitrary numbers — a spun wheel of fortune — dragged people's subsequent estimates toward them. The first figure becomes the reference point, and adjustment away from it is reliably insufficient.

What it means for events
Sequence your numbers deliberately. The first price, the first tier, the first benchmark shown sets the scale everything after is judged against — whether you chose it strategically or let it happen by accident.
Where to run it
Sponsorship & pricing
Present the flagship tier first. It anchors the scale; the middle tier then reads as reasonable instead of expensive.
ROI conversations
Open with the cost of the status quo — the pipeline not built, the deals lost — before the event budget appears against it.
Auctions & fundraising
The opening ask calibrates the room. Start where you want the average to live, not at the floor.
