Performance bias

- Happens when one group of subjects in an experiment (e.g., a control group or a treatment group) gets more attention from investigators than another group.

- Can also refer to the fact that participants can change their responses if they know which group they are allocated in. (A set of Hawthorne effect)

Observer bias (also called experimenter bias or research bias)

- Tendency to see what we expect to see, or what we want to see. When a researcher studies a certain group, they usually come to an experiment with prior knowledge and subjective feelings about the group being studied.
