Labor Relations Alternatives (LRA) Investigations Practice Test

Interest in the outcome affects credibility. When a witness has a financial or personal stake in how the case is decided, there’s a real risk of bias—they may be more likely to emphasize favorable facts, downplay unfavorable ones, or tailor their testimony to help their side. That potential bias makes their testimony less trustworthy than that of someone with no stake, who has less incentive to distort the record.

Proximity to events isn’t the sole determinant of credibility. Being close to what happened can improve memory accuracy, but credibility likewise depends on consistency, corroboration, and absence of bias. A witness with no interest can still be credible if their account is well-supported; and a witness with interest is not automatically discredited, but their credibility is generally viewed as weaker due to the stake involved.
