This project deals with the effects that Instagrams algorithms have on human behaviour in social settings, and on some users mental health. The project is based on theories about algorithms, social behaviour and health. Furthermore, it includes a study published by The Danish Health Authority in 2018. Since female users between the age of 16 and 24 have shown to be the most common users of Instagram, and the group with the highest percentage of mental health issues, they are this project’s main focus. The project includes four interviews with young women between 16 and 24 years of age.
