Which statement best captures the notes' stance on the credibility of alternative observations?

• A. All alternative observations are equally credible.
• B. Some alternative observations should be regarded as not credible.
• C. All observations are always credible.
• D. None of the observations should be trusted.

Answer: (B)

Evaluating credibility of observations involves recognizing that reliability varies from one claim to another. The notes suggest judging each observation on its own merits, based on how it was obtained, whether its methods are sound, whether the finding has been replicated, and whether it fits with other solid evidence. This leads to the idea that some observations should be regarded as not credible, because they come from flawed methods, biased sources, small or unrepresentative samples, or insufficient evidence.

Think of credible observations as those produced with careful measurement, transparent procedures, and support from additional data, while noncredible ones lack these safeguards. The stance captured here doesn’t assume every observation is trustworthy or automatically dismisses all observations; it emphasizes a thoughtful, case-by-case assessment.

That’s why this option is the best fit: it communicates the nuanced view that some observations are credible and others aren’t, depending on the strength and reliability of the supporting evidence.
