How can bias impact the outcome of research findings?

Bias can significantly impact the outcome of research findings by skewing the results, which in turn limits the validity of the research. When bias is introduced, whether through study design, data collection, or analysis, it can lead to conclusions that do not accurately represent the true situation or relationships being studied. For instance, if the sample population is not representative of the broader population due to selection bias, the findings may not generalize well. Similarly, confirmation bias can cause researchers to favor information that supports their hypotheses while disregarding information that contradicts them. This misrepresentation not only affects the integrity of the research process but also compromises the reliability of conclusions drawn from the data, ultimately impacting the decisions made based on those findings. Recognizing and minimizing bias is therefore crucial to ensure that research contributes valuable and accurate knowledge.
