CHIARO ― a tool to collect evidence of shadowban and other algorithmic abuses

By comparing individuals observation, we can understand how personalized and partial our perception is forced to be.

List of active CHIAROs (they can be many, imagine add your own if you’ve a research question)

This list can be updated by opening a pull request in this config file.

Why we did it?…

Takeaway: there is personalization on search results even if non of the above browser is logged in youtube.

CHIARO is helpful tool disigned to spotlight and list queries from many groups of people so we can see which content is algorithmicly promoted or shadowly banned

Because nor we or anyone else can’t say what is the best algorithm for you. We are here to remind you that your agency is not the one of Google.

In the same way a content is preferred for a specific profile, then something else get hidden
— in the name of that digital prejudice that a profile is

CHIARO is about all of this: We though your list of queries might cover aspects we couldn’t figure out as significant. For us, algorithmic transparency is pointless if we do not enable individuals and digitally organized research groups. We don’t pursue a victory in having platforms accountable only by teams of experts. These companies affect us all; we urge to reach a broader understanding of this phenomenon.
