This document discusses 7 cognitive biases that researchers should be aware of in their work: selection bias, observer-expectancy effect, framing bias, confirmation bias, groupthink and bandwagon effect, anchoring bias, and clustering illusion. It provides examples of each bias and recommends ways to prepare for, conduct, and analyze research to mitigate the influence of these biases. This includes using multiple recruitment channels, keeping an open mindset, considering alternative hypotheses, and collaborating with other researchers.
