Which of the following do legal researchers try to avoid when choosing a source?

validity

reliability

authenticity

bias

Bias

Explanation:

Choosing an authentic and significant source is crucial to an effective 'research'. Thus, while choosing a source, Legal researchers focus mainly on the authenticity, reliability, and validity of a source as it would affect the output of their research. Thus, the authenticity is of supreme concern while the thing that the researchers try to avert is that the source should not be biased as research can never afford to be biased as the biased source would mislead the research into an undesired path and a research is done not for a specified group of people but for a vastly diverse audience. Hence, the researchers tend to avoid the source being prejudiced or biased and confirms the reliability of the source before referring to it.
