The Importance of Credibility
Q&A Radio: 11 January 2015, Question 1
I answered a question on the importance of credibility on 11 January 2015. You can listen to or download the podcast of just this question below – or check out the whole episode of Philosophy in Action Radio.
Should a person's credibility matter in judging his empirical claims? Is it rational to use a person's track record – meaning the frequency or consistency of truth in his past statements – in judging the likely truth of his current statements? In Ayn Rand's Normative Ethics, Tara Smith explains that to believe something just because someone said it is a violation of the virtue of independence. Also, to judge an argument based on the speaker is known as the fallacy of "ad hominem." However, doesn't the character of the speaker matter when considering whether to believe his claims? For example, when Thomas Sowell makes an empirical claim, my knowledge that he vigorously tests his hypotheses against the facts makes me more likely to judge his claim as true, even before I've confirmed his statement. Likewise, if a person is frequently wrong in his factual claims, I'd be sure to require lots of evidence before believing him. Is that rational? Or should all factual claims be treated equally regardless of who makes them?
My Answer, In Brief: The credibility and track-record of the person who asserts a claim matters. Along with many other factors, it's not proof or evidence of truth, but it's can be reason to take an idea seriously or regard it as plausible.

About Philosophy in Action
I'm Dr. Diana Brickell. I'm a philosopher specializing in the application of rational principles to the challenges of real life. I received my Ph.D in philosophy from the University of Colorado at Boulder in 2009. My book, Responsibility & Luck: A Defense of Praise and Blame, is available for purchase in paperback and Kindle. The book defends the justice of moral praise and blame of persons using an Aristotelian theory of moral responsibility, thereby refuting Thomas Nagel's "problem of moral luck."
My radio show, Philosophy in Action Radio, broadcasts live over the internet on most Sunday mornings and some Thursday evenings. On Sunday mornings, I answer questions applying rational principles to the challenges of real life in a live hour-long show. Greg Perkins of Objectivist Answers co-hosts the show. On Thursday evenings, I interview an expert guest or discuss a topic of interest.
If you join us for the live broadcasts, you can ask follow-up questions and make comments in the text-based chat. Otherwise, you can listen to the podcast by subscribing to our Podcast RSS Feed. You can also peruse the podcast archive, where episodes and questions are sorted by date and by topic.
