Epistemology of Bias

According to our ordinary thought and talk, many sorts of things can be, and often are, biased: people, groups (the biased committee), inanimate objects (the biased coin), sources of evidence (biased samples, biased testimony, biased surveys), mental states (biased perceptions, biased beliefs), the outcomes of deliberation (biased decisions, biased evaluations), and algorithms. The course will be divided into two parts. In the first part of the course, we will ask what it means to say that someone or something is biased. Among other things, we will ask whether people are biased in the same way as surveys are biased, and whether surveys are biased in the same way as algorithms are biased. In the second part of the course, we will examine some specific forms of bias in reasoning: hindsight bias, confirmation bias, status quo bias, among others. What, exactly, are the cognitive mechanisms underlying these biases? And are they always irrational?
