We Live in a World of Funnels

Precision, accuracy, and the paths we erase

A funnel turns a journey into a sequence of stages: arrive, look, choose, finish. That makes losses easy to compare. But people also go back, try again and leave for reasons a narrowing shape cannot show.

Compare totals in the funnel, then follow the returns and detours in the flow view.

Candy Shop: the funnel as evidence

A funnel uses width to compare how many people reach each stage. It is a useful first view when stages follow a clear order. To understand what happens between them, we need to inspect the paths people take.

Precise readingThe stage strip, leak tape, and funnel agree on the biggest narrowing.

A/B funnels reward the intervention that moves the line

Teams use funnels to compare cohorts and test designs. The vertical view shows how many people continue and how many leave at each step, helping locate the largest difference between versions.

Precise readingEqually effective here: cohort testing is a straight comparison, so the ordered funnel is the right instrument.
03

Precision says the story is shrinking

Switch views to examine the same case. The funnel emphasizes losses between ordered stages. The flow view adds repair, rereading, searching and exits, giving you more specific questions about where the design could improve.

Precise readingThe chart compresses the case into one comparable path.
04

Motifs are paths with names

A process Sankey adds the time spent on each route. Repair and comparison loops occupy time and capacity even when people eventually reach the intended destination.

Precise readingThe temporal view still works, but particles pause so path volume and timing carry the comparison.

The Semiotic point

Precise readingThe conclusion treats the funnel as a sharp measuring instrument.

Use the funnel to find where journeys differ, then inspect the routes that explain the difference. The two views help answer related questions: how many people continued, and what they did along the way.
