An online marketplace piloted a ranking model that promoted unfamiliar sellers. Buyers exposed to the model purchased from a wider range of sellers and returned more often 30 days later. The company concluded that seller diversity increased retention.
However, the pilot was offered only to buyers who had previously browsed at least five seller pages. The treatment also shortened the delivery estimates shown on product cards.
Which additional finding would most seriously weaken the company’s interpretation?
Strong reasoning.
That result removes both plausible confounders and eliminates the observed lift, directly weakening the claim that seller diversity caused retention.
