The document discusses filter bubbles and media literacy. It summarizes Eli Pariser's work on filter bubbles and how personalized algorithms can limit exposure to diverse perspectives. It also analyzes how Facebook designs its interface using A/B testing to maximize user engagement, such as showing fewer larger friend suggestions. The consequences of filter bubbles mentioned are polarization, incomplete information exposure, potential effects on social behavior through internalizing coded norms, and lack of input into algorithmic personalization systems due to business secrecy and complexity.

“Un tel pouvoir a à qualifier, à mesurer, à apprécier,
à hiérarchiser, plutôt qu’à se manifester dans son
éclat meurtrier”
(Foucault, 1976)
“Power is defined, from this perspective, as the
capacity to structure the field of action of the other,
to intervene in the domain of the other’s possible
actions.”
(Lazzarato 2002)

11. Biopower in Facebook design
“Every day, we run hundreds of tests on Facebook, most of
which are rolled out to a random sample of people to test
their impact.“
“when people go to find friends, we used to show as many
names and faces as we could fit on the screen to minimize
scrolling. We ran a test which instead reduced the number of
people we showed per page by 60% but gave each more
space and a larger button to engage with, and we saw a 70%
increase in friend requests. Given a more consumable
interface, people were more able to find people they wanted
to connect with. This may sound obvious but, in the words of
growth engineering manager Mike Curtis, "It's always obvious
why the winning test won... after you've run the test.””
