The Monty Hall problem is a strange result arising from a very simple situation. In this video, Bryce Gessell (Duke University) explains why it seems so counterintuitive and why the solution isn't counterintuitive at all.
In the second of two videos, Adela Deanova (Duke) introduces Margaret Cavendish, an early modern English philosopher, and discusses the background to her critique of experimental philosophy. This video is a part of a series of videos coming from Project Vox (Duke), a project recovering the lost voices of women philosophers.

In part 2, Andrew Janiak (Duke) further introduces Emilie Du Chatelet, a French philosopher, and her contribution to the debate about the principle of sufficient reason. This video is a part of a series of videos coming from Project Vox (Duke), a project recovering the lost voices of women philosophers.
In this video, Molly Gardner (UNC) introduces the nonidentity problem. This problem arises in cases where an individual appears to be wronged by the very action upon which his or her own existence depends. We’ll see why this problem has implications for reproductive choices, genetic engineering, and whether we should take care of the environment for the sake of future generations.
In this video, Michael Campbell introduces the Sleeping Beauty problem. This is a problem in formal epistemology about how to correctly assign probabilities to an odd scenario in which we flip a coin and, depending on the outcome, wake Sleeping Beauty up according to two different patterns. We’ll discover some very strange consequences for our beliefs as a result.
In this video, Paul Henne (Duke University) explains the post-hoc-ergo-propter-hoc fallacy. This is an informal fallacy committed when a person reasons that because one event happened after another event, the first event caused the second. He also discusses why it is sometimes hasty to conclude that your cat scratch caused your fever.
In this video, Justin Khoo (MIT) picks up where part 3 (http://youtu.be/Oxt1DdfT8ME) left off. He introduces the Conditional Assertion Theory of conditionals, which aims to resolve the problems presented for the other theories of conditionals. In the end, Justin presents yet another problem for this radical new theory.
In this video, Jordan MacKenzie discusses a type of informal fallacy known as the argumentum ad populum fallacy, or the appeal to the people fallacy. This fallacy occurs when one attempts to establish the truth of a conclusion by appealing to the fact that the conclusion is widely believed to be true.
In this Wireless Philosophy video, a Yale University philosopher builds on the understanding of necessary and sufficient conditions laid out in her previous video on the topic (youtu.be/5LqNm9d2__I). In addition to providing further illustrative examples, Kelley addresses a new complexity: that our judgments of necessity and sufficiency very often rely on implicit background assumptions. Kelley also tackles the difficult question "What's so important about distinguishing necessary from sufficient conditions anyway?".
In part 3 of the series on conditionals, Justin picks up where part 2 (http://youtu.be/Xs6E-FEls1c) leaves off, introducing an alternative theory of conditionals: the strict conditional theory. According to the strict theory, conditionals express necessary connections between their antecedent and consequent. Justin shows how this theory avoids the problems facing the material conditional theory. However, the strict theory turns out to face a similar problem of its own!
Justin Khoo (M.I.T.) invites us to think about conditional sentences ("if P then Q"). Perhaps surprisingly, the question of what these sentences mean has vexed philosophers for thousands of years. In part 2 of the series on conditionals, Justin discusses some of the challenges facing the material conditional theory, picking up where part 1 (http://youtu.be/4Zxp2-_pLCE) left off.
In this video, Geoff Pynn (Northern Illinois University) follows up on his introduction to critical thinking by exploring how deductive arguments give us reason to believe their conclusions. Good deductive arguments guarantee their conclusions, and so must be valid (i.e., it must be impossible for the premises to be true while the conclusion is false) and have true premises. Philosophers call arguments like these "sound". You can see whether an argument is sound by trying to think of a counterexample to it, but to see whether its premises are true, you need to do some research.
What is human nature? Is human nature good or bad? Can human nature be good even if the world contains some notably bad people? Matthew Walker (Yale-NUS College) looks at the views of the early Confucian thinker Mengzi (Mencius).
In this video, Julianne Chung (Yale University) offers a brief introduction to ad hominem fallacies, or fallacies of personal attack. She surveys six different types (abusive ad hominem, circumstantial ad hominem, tu quoque, guilt by association, genetic fallacy, and ad feminam), offering examples of each along the way. For a more detailed discussion of ad hominem fallacies, please see the video on ad hominem fallacies by Paul Henne (Duke University).
