How can I minimize observer bias in my research?

You can use several tactics to minimize observer bias.

  • Use masking (blinding) to hide the purpose of your study from all observers.
  • Triangulate your data with different data collection methods or sources.
  • Use multiple observers and ensure interrater reliability.
  • Train your observers to make sure data is consistently recorded between them.
  • Standardize your observation procedures to make sure they are structured and clear.
