NHS: implementation intentions example to copy

What to steal

State the when: how often, and what happens on the days in between.
Give the plan an end the person can picture. Here it is running 5K.

What to test next: “3 times a week, with rest days in between and a fresh schedule to follow each week” vs a page that only says “start running”. Measure plans started and week-1 runs logged.

In plain words

Why it works

The NHS uses implementation intentions: a plan that says when and how you will act is easier to follow than a goal on its own (Gollwitzer 1999). Under “What is Couch to 5K?” the page says “The plan has you running 3 times a week, with rest days in between and a fresh schedule to follow each week.” The next paragraph names the end: “By the end, you’ll be running 5K with confidence, no matter your starting fitness level or when you last exercised.” The when is the three runs and the rest days. The how is a fresh schedule each week. Whether that schedule lifts the number who finish is not public.

Honest nudge or dark pattern?

Honest nudge

Honest nudge: the schedule is specific, the programme is described as free, and it is written for absolute beginners who want to start.

Context

NHS Better Health, “Get running with Couch to 5K”, logged out, on 4 Nov 2026. Analytics cookies were rejected. This crop is the “What is Couch to 5K?” section. Above the plan it says the programme is “a simple, free running plan for absolute beginners.” A yellow box reads “Couch to 5K was created by a new runner, Josh Clark, who wanted to help his 50-something mum get off the couch and start running too!”

Pattern: NHS: NHS Couch to 5K sets the runs at 3 times a week
Bias: Implementation intentions: Planning exactly when, where and how we'll act makes us more likely to follow through.

Rules: say a brand "uses" a tactic, never that it "worked"; outcomes are not public unless the company published them; no invented uplift estimates; flag mixed evidence. Honest nudge = true, visible, easy to reverse, and in the user's interest. Dark pattern = hides costs, fakes scarcity or popularity, shames, or makes leaving harder than joining. Quote company-published results as "X reports", with the source link, and don’t generalise them. Don’t cite retracted or failed-to-replicate studies as support (e.g. Ariely & Wertenbroch 2002). Don’t state study figures unless they’re on this page or in a source you can link. If an idea crosses the line, link the matching deceptive.design pattern.

Tasks:
1. Ask me for my product, the flow (URL or screenshots) and the goal.
2. Audit where this pattern already appears, or could, in that flow.
3. Propose 2-3 ethical experiments: hypothesis, variant copy or UI, primary metric, and a guardrail metric (refunds, complaints, cancellations).
4. Flag every dark-pattern risk and say how to stay on the honest side.
