Post‑Decision Relaxation

The parasympathetic downregulation that occurs immediately after a person makes a significant decision. Once a purchase is authorized, the brain’s deliberative systems disengage, heart rate may drop slightly, and mental resources that were locked onto the transaction are freed. This state is pleasant but fragile. Any new demand for a financial decision — such as an upsell offer on the thank‑you page — interrupts the relaxation and is processed as an intrusion. Post‑decision relaxation explains why post‑payment offers have low conversion rates; the user wants closure, not a new decision.

Example: Aggregate checkout data from Bolt and Fast shows post‑payment offers converting at approximately 4.7%, largely because they land during post‑decision relaxation rather than during a receptivity window.
