Thomas and Simone discuss the problems with using averages. Social Media: iTunes: The Surplus Population [email protected] Twitter: @surpluspop Istagram: My “Genuinely Good Conversation” episode: Show notes for "The Problem With Average" by timestamps: 0:45 The average person has one testicle: 1:45 Mean: good for bulk properties 6:00 Example of media misusing “average” (mean) 7:15 The mean cell life is a few years. But, your body does not “renew every cell over seven years.” In fact: “Some cells are made and they're killed off, and replaced very, very regularly, very, very rapidly, blood cells last 120 days for example, others do have to genuinely last you a lifetime.” 7:50 Infant mortality drags down life expectancy 9:30 Actuarial tables: 10:45 Median: 11:30 Average US income $72,641 12:10 Median US income $54,462 16:05 Mode: finds the most important groups 16:30 Multi-modal: 18:25 Height Distribution: Hmm, wikipedia says “The combined distribution of heights of men and women is sometimes used as an example of a bimodal distribution, but in fact the difference in mean heights of men and women is too small relative to their standard deviations to produce bimodality.” Interesting. Maybe I was wrong to use it as an example. 20:20 Amazon wish list of a teacher (softcover vs hardcover): 21:45 Color spectrum in different languages 22:45 Linguistic relativity 24:00 Life expectancy of cats/dogs/humans 25:25 Malcolm Gladwell TED talk on pasta sauce 29:00 Gavin McInnes Battles Tamara Holder: 'You'd Be Much Happier At Home with a Husband and Children' (This clip is presented under US fair use copyright law) 29:40 By the way, he’s also committing the “Ecological fallacy”: “a logical fallacy in the interpretation of statistical data where inferences about the nature of individuals are deduced from inference for the group to which those individuals belong.” 32:15 Poe’s Law's_law 37:10 Average Attractiveness from oktrends. Looks like there is some modality to people’s ratings. So I was wrong on that. 38:15 Also, as I mentioned “women rate an incredible 80% of guys as worse-looking than medium” 39:30 Average Penis Length: ~5”, Gaussian, Standard deviation 1” 41:00 Women cheat for love (57% feel love for lover compared with 27% for men) 44:50 Big Five 48:45 Malcolm Gladwell TED talk on pasta sauce

Email us: [email protected] Show notes: Nobel Prize in Discovering Neutrinos have mass: 100 trillion neutrinos passing through you: 1:55 More particly than wavy: “Neutrino: An electrically neutral, weakly interacting elementary subatomic PARTICLE. [emphasis mine]” 3:15 Neil Degrass Tyson Clip 4:30 Forces interacting with Neutrinos "Neutrinos are affected only by a 'weak' sub-atomic force of much shorter range than electromagnetism, and are therefore able to pass through great distances in matter without being affected by it. If neutrinos have mass, they also interact gravitationally with other massive particles, but gravity is by far the weakest of the four known forces." (written before the discovery that neutrinos have mass) 15:15 This is the Nietzsche piece I was trying to quote about no one remaining in the infinitely skeptical state. "[The intuitive man] suffers more frequently, since he does not understand how to learn from experience and keeps falling over and over again into the same ditch." "On Truth and Lie in an Extra-Moral Sense" Frederich Nietzsche 16:20 "Pyrrho is said to have been so seriously bound to skepticism that it led to his own unfortunate and sudden death around 275 B.C.E. According to the legend, he was demonstrating skepticism while blindfolded when his disciples tried to warn him of a dangerous cliff he was headed toward. He refused to believe them, and thus, his life ended abruptly. The historical accuracy of this claim is, however, doubtful." 20:40 "Not a scientific claim example" 26:40 Concrete and Abstract Objects 29:15 "Proof of Heaven" 34:20 Hanlon's razor: "never attribute to malice that which is adequately explained by stupidity" 35:55 Credits: Thomas Long (host, editor, researcher, artist) Jaen Simone Hawkins (host, manager)
