- IDEA 1 OF 8
The internet shows us ourselves
Pariser argues that websites increasingly personalise what each user sees based on past behaviour.
As a result, people end up in a filter bubble, surrounded mainly by information that matches their existing views.
- IDEA 2 OF 8
Search results differ by person
Pariser describes how Google began personalising search results in 2009.
Two people searching the same word could see very different results. This meant that the web a person saw was becoming more and more personal.
- IDEA 3 OF 8
News feeds filter friends
Pariser describes how Facebook's news feed chooses which posts users see.
He noticed that posts from people with different political views disappeared from his feed. Pariser saw this as a sign that unseen sorting can narrow our view.
- IDEA 4 OF 8
The editing is invisible
Pariser argues that the danger is that users do not know what is being filtered out.
They cannot see the choices made for them. Unlike a newspaper, a hidden filter gives no hint of what was left out.
- IDEA 5 OF 8
Surprise disappears
Pariser argues that personalisation reduces serendipity, the chance to discover unexpected ideas.
Learning needs exposure to the new. When feeds show only what we already like, the odd and unexpected find fewer chances to reach us.
- IDEA 6 OF 8
Democracy needs shared facts
Pariser warns that filter bubbles may weaken democracy, which depends on citizens sharing information and debating.
If people see very different versions of events, it becomes harder to agree on problems or solve them together.
- IDEA 7 OF 8
Algorithms have values
Pariser argues that algorithms are not neutral.
They reflect choices made by the companies that design them. Decisions about what to rank, show or hide are shaped by human goals, such as keeping people clicking.
- IDEA 8 OF 8
Companies must be responsible
Pariser calls on tech companies to make filtering transparent and give users more control.
He also encourages users to seek out different views. In his view, both companies and users have a part to play in keeping the web open.
