How Young People Use the TikTok Algorithm

When Filtering Distorts Body Image

Due to beauty filters, young people are often confronted with unrealistic beauty ideals on social media. This can lead to body image disorders as well as eating disorders. So should edited images be labeled? Not a good idea, says an expert opinion by the HBI on behalf of the KJM: The legal requirements for an enforceable legal regulation are high, and the positive effects of labeling are controversial. Instead of a legal labeling requirement, the algorithms of the platforms could be adapted to promote more diverse and realistic body representations.
