There will be brief presentations by Aviv Ovadya on bridging-based ranking and platform democracy intermixed with discussions and commentary, and ending with Q&A.

Jeff Allen (Integrity Institute; ex-Facebook) will add context on recommendation systems and the challenges and opportunities of bridging-based ranking

Claudia Chwalisz (OECD) will provide color on ‘representative deliberative processes’, one of the democratic approaches most appropriate for platform democracy. She leads the O.E.C.D.’s work on innovative citizen participation, and has been a significant contributor toward institutionalizing such processes.

While neither of the approaches explored in this discussion are silver bullets, they both aim to provide pragmatic paths forward—moving beyond some of the dead ends of platform accountability conversations that have slowed meaningful progress for many years.
