Dear all,

You are warmly invited to the next MQ Philosophy Work in Progress (WIP)
seminar which will be given by *Adam Piovarchy (Notre Dame)*

The details are as follows:
Date: Tuesday 24th of March
Time:   13:00-14:00
Room: 17WW 113

*Title: Conspiracy Theories and the Ways of Bayes*

*Abstract:* Is there something epistemically defective about conspiracy
theories as a class? Generalists argue there is something about conspiracy
theories that makes them generally unjustified, unlikely, or less credible
than other kinds of explanations. Particularists, in contrast, deny this.
Because many conspiracy theories are true, just as many non-conspiracy
theories are false, we should evaluate individual conspiracy theories
according to the evidence for each. This paper argues for a defeasible
generalism by taking a closer look at what would count as strong evidence
for or against a conspiracy theory. Using Bayes’ theorem, I illustrate how
several argumentative moves made by both conspiracy theorists and
particularists incur significant costs that are often overlooked. The ease
with which conspiracy theories’ content lends themselves to these moves
leads people to misunderstand when they have evidence for a conspiratorial
hypothesis. Scepticism of conspiracy theories is thus generally warranted
as a corrective to their tendency to be misleadingly convincing.

Please note: this talk assumes some familiarity with Bayes' theorem; any
popular YouTube explainer will suffice.
