Put simply, "Group 7" refers to a TikTok trend started by singer Sophia James while promoting her new single, "So Unfair." Hoping to get as many ears on her song as possible, James uploaded seven nearly identical videos with a simple premise: whichever one appeared on your For You Page determined which "group" you belonged to.

In October 2025, James launched a social experiment to promote her new song, "So Unfair," testing which of her seven videos would reach the largest audience.
