How to avoid confirmation bias in research?

To avoid confirmation bias in research, it is important to:

• Formulate hypotheses and research questions in advance, without tailoring them to expected results.
• Use blind or double-blind methods, where the researcher does not know the expected outcome.
• Actively seek and analyze data that may disprove your hypothesis.
• Involve independent colleagues to review and critique the results.
• Use diverse data sources and research methods for cross-verification.
• Document the research process in detail to track possible biases.

For example, when testing a new product feature, it is important not only to look for confirmation of its usefulness but also to gather feedback indicating possible problems or inconveniences.
