Social Engineering
Social Cross-Sell
Other customers bought this. And this. And this. (Allegedly.)
What is it?
A product page displays 'Customers who bought this also bought…' recommendations that are engineered for revenue, not relevance — fabricated social proof disguised as helpful discovery.
How it works
The pattern changes the cost of thinking. It makes the preferred action immediate, emotionally charged, or visually dominant, while making the more reflective action slower, duller, or easier to doubt.

Real World Example
- A pair of shoes triggers 'Customers also bought premium insoles' from a simulated sample.
- Multiple 'other buyers' are shown as recent notifications alongside cross-sell items.
Origin: Ecommerce, checkout pages, SaaS upsells, and post-purchase flows.
Ethical Alternative
Show genuinely correlated recommendations based on real purchase data, label them clearly, and avoid implied urgency.
