When we analyze our results it’s hard to evaluate the outcome in an objective manner. It’s us humans that tend to fall in love with every idea that pops into our head. Science also had this problem and that’s why they came up with double-blind experiments, to tackle bias when looking into your results. Thanks Philip
Performing an experiment in double-blind fashion can greatly lessen the power of preconceived notions or physical cues (e.g., placebo effect, observer bias, experimenter’s bias) to distort the results (by making researchers or participants behave differently from in everyday life). Random assignment of test subjects to the experimental and control groups is a critical part of any double-blind research design.
Curious to learn how you prevent bias when analysing your experiments?
See you next week!
