Why the answers change

Ask an assistant the same question twice and the list moves. It changes between runs, between people, and with whatever the assistant found when it searched that day. These are the answers we got on the dates shown, asked with no account history and no location. We ask again every month with the same wording, so the next set can be compared with this one.

A brand missing from these lists is not a verdict on the brand. It means a shopper asking this question on this day would not have heard of it from the assistant.
