Laws of UX · Experience and trust
Peak-End Rule
People judge an experience largely based on how they felt at its peak and at its end, rather than the total sum or average of every moment of the experience.
The design-system take
Where the principle shows up in a token, component or pattern decision.
Invest in the confirmation screen and the empty state — the moments users actually remember. A flawless middle cannot rescue a bad ending.
