Understanding and minimizing bias in scientific experiments is crucial for the integrity of research. Bias can stem from various sources, such as researchers' prejudices, participant selection, and experimental design. Strategies like blinding, representative sampling, and thorough reporting are vital to reduce bias and ensure reliable, generalizable results. Examining historical examples helps researchers design unbiased studies.
