  1. What's a real-world manifestation of the #conjunctionFallacy?

    A contrived case:

    "Linda is 31 years old, single, outspoken and very bright. She majored in philosophy. As a student, she was deeply concerned with issues of discrimination and social justice, and also participated in anti-nuclear demonstrations.

    Which is more probable?
    A. Linda is a bank teller.
    B. Linda is a bank teller and is active in the feminist movement."

    82% chose B (violating the conjunction rule)

  2. Another #framingEffect?

    In "The Allure of #Simplicity", Jack Justus, Samantha Wakil and I run three #experiments on people's evaluations of explanations.

    Merely labeling explanations 'simpler' or 'simplest' made people more vulnerable to the #baseRateFallacy and the #conjunctionFallacy!

    Jack and I present our data and conclusions at #PSA2022 on Saturday.
