What is the impact of the researcher's bias on the study?

The impact of the researcher's bias on the study is significant because it can shape both the study's design and how the collected data is interpreted. When a researcher harbors biases, whether they are conscious or unconscious, these opinions can affect a variety of processes, from the formulation of research questions to the selection of methodologies, as well as the analysis of results.

For example, if a researcher has a preconceived notion about the outcome of their study, they may inadvertently skew their data collection methods or choose to highlight certain results while downplaying others. This subjectivity can lead to a distortion of findings, which misrepresents the true nature of the research outcomes. Therefore, understanding and acknowledging bias is crucial in studies to ensure the validity and integrity of the data, allowing for a more accurate and reliable representation of the phenomenon being examined.

In contrast, minimizing research complexity, enhancing reliability, or improving participant engagement do not fundamentally capture how bias directly affects the core processes of research. Bias typically introduces complications rather than reducing them, and while it might engage participants in certain contexts, it does not ensure that the research outcomes are valid or reliable.
