The research, plainly
Tversky and Kahneman's disease-outbreak experiments showed identical outcomes flipping preferences when described as lives saved versus lives lost. The information was constant; the frame drove the decision.

What it means for events
Every stat in your deck and every line in your invitation is a frame choice. Show rate or no-show rate, cost or investment, risk of acting or risk of waiting — the numbers won't decide which; you will, or chance will.
Where to run it
Invitations
'Join the 90% of your peers who attend' and 'don't be in the 10% who miss it' are the same fact wearing different clothes. Test both.
Executive readouts
Frame event ROI against the cost of inaction — pipeline not created — not just against the budget line.
Change events
Frame the new way as what's gained by moving and what's lost by staying. One frame alone leaves half the motivation unclaimed.
