Episode 3: Confirmatio Praeiudicia

1 hour 1 minute

In our third episode, we discuss confirmation bias, which affects not only how scientists generate and test their own hypotheses, but also how they evaluate the scientific evidence presented by others. We discuss guardrails against confirmation bias that are already in place, and others that could potentially improve scientific practice if adopted.
