This is unethical psychological research against non-consenting adults and children that likely caused real harm. From a paper cited below, > This Facebook study was conducted without consent and without appropriate oversight, and may have harmed both participants and non-participants. Kramer’s apology also puts the vast number of participants in context; a full 0.04% of Facebook’s users, or 1 in 2500, were unwitting subjects in this unethical research. Many of these people were almost certainly children, and many of the participants were probably suffering from depression. It is surprising and worrying that one of the world’s most prominent companies should treat both the emotions of its users and research ethics so carelessly. Steps must be taken to ensure that international psychological and medical studies involving social network users are regulated to the same standard as other human subjects research. https://journals.sagepub.com/doi/10.1177/1747016115579535 https://journals.sagepub.com/doi/10.1177/1747016115579535 Edit: Also you said something that confused me, > given they are only analyzing data they already gather? I'm not sure what this means. But they did not only analyze existing data, they created new data specifically intended to make people feel sad, then analyzed that data.
