Oxford Events, the new replacement for OxTalks, will launch on 16th March. From now until the launch of Oxford Events, new events cannot be published or edited on OxTalks while all existing records are migrated to the new platform. The existing OxTalks site will remain available to view during this period.
From 16th, Oxford Events will launch on a new website: events.ox.ac.uk, and event submissions will resume. You will need a Halo login to submit events. Full details are available on the Staff Gateway.
To what extent is it possible to manipulate beliefs by providing interpretations of unknown events? I characterize the feasible posteriors across signals when the agent is exposed to a set of models to interpret observable signals and adopts the model that best fits what is observed. Because each signal could trigger the adoption of a different model, posteriors across signal realizations might not average to the prior. The scope of persuasion is large, even for a persuader who does not control or know the signal the agent observes. I apply this framework to political polarization, finance, lobbying, and self-persuasion.
