Does it cause hairy palms? (No, that is a myth.) Will it make you go blind? (No, though zinc deficiency can be detrimental to one's vision, and semen contains a small amount of zinc.) Are you going to hell for it? (Maybe, maybe not.) But what if it helps with conception? (well, the men doing it, anyway)

Indiana Jones and... the Kingdom of the Crystal Skulls? Actor Shia LaBeouf announced the title of the new Indiana Jones movie at the MTV Video Music Awards. But what was George Lucas' inspiration? Where did these Crystal Skulls come from? These ancient objects have been referenced in many places, including an episode of StarGate SG-1, imaginatively titled "Crystal Skull". There is also a Festival and a not-for-profit Foundation dedicated to researching these artifacts.

Persistence of Myths Could Alter Public Policy Approach. "The conventional response to myths and urban legends is to counter bad information with accurate information. But the new psychological studies (PDFs) show that denials and clarifications, for all their intuitive appeal, can paradoxically contribute to the resiliency of popular myths." [Via Firedoglake, more at MindHacks.]

Pirate myths debunked. Slate's Explainer attacks your favorite pirate stereotypes: walking the plank, saying "arrr." Not a myth: pirate republics. Pirates formed egalitarian mini-states based upon utopian values, a prime reason for their brutal suppression by European authorities.

What are the greatest hoaxes in rock history? [MP3 links] They Might be Giants' John Flansburg tells John Schaefer what he knows, and Rolling Stone readers weigh in as well. Was it Mama Cass choking on a sandwich? Jack and Meg White as siblings? Paul dead (again)? Keith Richards getting his blood replaced? Or snorting his father's ashes? Oh, wait, that last one was true.

From a New York journalist's description of the days after the flood:

I saw persons take watches from dead men's jackets and brutally tore finger-rings from the hands of women. The ruffians also climbed into the overturned houses and ransacked the rooms, taking whatever they thought valuable.

Sound familiar? This report about the Johnstown Flood was also filled with stories of "minority savegery", drunken Hungarians at the time that eventually turned out to be completely untrue or wildly exaggerated, such as the rescue helicoptor being shot at. also see previous mefi thread on LA looting here

Class Mobility within America - The mythology surrounding Horatio Alger is a powerful force within American culture: the idea that anyone can pull oneself up by the bootstraps to become financially successful. Surprising research by statistician Miles Corak shows that Americans have no more income mobility than Europeans — contradicting cultural presumptions of egalitarianism — and even less than Scandinavian countries, despite their heavy taxation. Marketing slowly meets reality in the American Dream...

The Skeptic's Dictionary is a wonderful resource for all sentient individuals: 'A Collection of Strange Beliefs, Amusing Deceptions, and Dangerous Delusions (and how to think critically about them)'. It's where I send people when they start telling me nonsense. It is also a jolly good read: try the entry for natural, for example. And some entries, like the entry for IQ and race, verge on the profound. There is a print edition, but the extensive internal and external site linkage makes reading the collection online a particular joy. While The Skeptic's Dictionary has been referred to before on MeFi, the link made the site out to be a cornucopia of Urban legend-style oddities, like Snopes. Which I thought was a shame: not dissing Snopes, but the Skeptic's Dictionary delivers a firm grounding in critical thinking as well. This post is dedicated to all of my relatives who chipped in to buy shark cartilage tablets and several fifty-dollar pamphlets full of testimonials after my father had been diagnosed with terminal cancer, and who probably still think the worse of me for not contributing to their folly.

Four out of 10 people mistakenly believe it is possible to get HIV by sharing a drinking glass or being coughed or sneezed on by an infected person. The survey, released Thursday, was conducted by the Centers for Disease Control and Prevention. "It's scary that so many people are still so ignorant of what causes HIV-AIDS," said Marty Algaze, a spokesman for the Gay Men's Health Crisis. "Almost 20 years into this epidemic, it's disturbing that people think you could still get it from casual contact."
