Goal-gradient effect
People speed up as they near a goal, and even the illusion of progress accelerates them. Split long goals into short sub-goals and make the remaining distance visible. Field evidence from loyalty programs (B+).
Plain label: effort speeds up near the finishAlso known as: goal gradient, progress bars, distance remaining
Core idea. In a cafe loyalty program, members bought coffee more often as they approached the free one, and a 12-stamp card with 2 stamps pre-filled beat a blank 10-stamp card needing the same purchases Evidence grade B. Moderate evidence: solid studies with some limits.. Effort tracked the proportion of distance remaining. F09 (The goal-gradient hypothesis resurrected, Kivetz, Urminsky & Zheng, Journal of Marketing Research, 2006)
How it plugs in. Progress bars for setup and profile completeness; weekly goals, chapters and levels; "2 lessons to your weekly goal" framing in the second half of a goal; tier thresholds users can see.
Watch-outs. Motivation can sag in the middle of long goals, so add a mid-journey boost. Only show progress that is real.
