Which statement best describes credibility in the presence of bias?

• A. Bias means the witness is always lying.
• B. Bias has no effect on credibility.
• C. Bias impeachment may reveal motive to misrepresent, affecting credibility.
• D. Bias only affects memory.

Answer: (C)

Bias affects how believable a witness is because it can reveal a motive to misrepresent the facts. If a witness has something to gain or a stake in the outcome, they may tailor their testimony to help one side, which undermines reliability. Impeachment based on bias highlights that motive and helps jurors weigh the truthfulness of what’s said. This isn’t a blanket claim that they’re always lying, nor that bias only affects memory, nor that bias has no effect; it’s about understanding that bias can color testimony and reduce credibility, so such testimony should be examined with extra scrutiny and corroborated when possible.
