Do streaming platforms trap us in cultural filter bubbles? We like to think so but the evidence says otherwise. In a new paper @abelaussant.bsky.social and I find the use of streaming platform to be associated with an increase in consumption diversity. sociologicalscience.com/articles-v12...
Screenshot of the title and abstract of the article. the title is Streaming Platforms, Filter Bubbles, and Cultural Inequalities. How Online Services Increase Consumption Diversity. The abstract reads: Do digital technologies affect diversity in cultural tastes? Digital sociologists have warned of “filter bubbles,” whereas sociologists of culture have shown that diversity in consumption is valued as a marker of upper-middle-class status. We estimate the effect of using streaming platforms on the diversity of cultural consumption using a matching technique applied to 2018 survey data from France. We find a statistically significant positive effect of using streaming platforms on the diversity of cultural consumption as well as on cosmopolitanism, on three domains, music, movies, and TV shows. The magnitude of this effect is much higher for TV shows. The study brings new evidence against the filter bubble thesis; it shows that platforms do reinforce cultural inequalities by increasing the social gap in consumption diversity. It further suggests that the effect of technology on cultural consumption might mainly operate through its impact on cultural markets rather than changes in cultural experience. Main figure of the article. Difference in number of genres consumed, liked, and disliked between streaming users and non-users. Streaming users consume more genres than non-users after controlling for confounders. The difference is small for music (0.1 sd), moderate for movies (0.2 sd), and high for TV shows (0.46 sd). However, differences in number of genres liked or disliked are small or not significant. SMD before (light) and after (dark) adjustment through matching, with error bars indicating 95 percent confidence interva

En France, la pollution aux particules fines augmente l'absentéisme des salariés, baisse leur productivité, affecte les consommateurs et nuit in fine aux entreprises.
