Social proof in healthcare: describing the norm changes behaviour
The situation
Appointment reminders are sent, the advice is clear, and adherence still sits well below where it should be. Information was never the constraint.
Why it works
People follow what they believe others like them actually do. Stated the right way round, that is one of the strongest levers in behaviour change; stated the wrong way round, it backfires. Announcing that most patients miss appointments tells patients that missing appointments is normal.
What to do
Describe the behaviour you want as the norm, when it truthfully is. "Nine in ten patients at this clinic complete the course" outperforms both a warning and a plea — and it costs nothing but a change of sentence.
Publicising a problem by advertising how common it is. If the desired behaviour is genuinely the minority, do not invent a majority — switch to a different principle rather than a false statistic.
Social Proof is one of seven principles identified across four decades of peer-reviewed research. Read all seven, or see how they apply to healthcare professionals.
