Some Biases in Data Science

Data Scientists are beset by potential biases, which lead to skewed analysis results and predictions. Some of these biases, such as biased data and algorithm bias, have received extensive coverage in the press and popular science books. Biases that are more specific, such as selection bias, metric bias, and reporting bias, are less widely reported. Lesser-known biases, such as pool bias, only affect sub-areas of Data Science. This talk gives a rapid overview of these biases, including examples of their occurrence and their effect. The influence of the combination of these biases on the reliability of published results is discussed, along with various paths toward improved awareness and reduction of bias.
