Skeptoid #797: Why You Need to Care About Methane

Wondery Suspect podcast preview

A big Halloween party at an apartment complex in Redmond, Washington. Themed rooms and costumed partygoers. But by the end of the party, one of the hosts is dead. The police look to the partiers as the prime suspects: was it the guy in the devil mask, the bank robber, the construction worker? As investigators comb through forensic evidence, witness testimony, DNA, and even consult with a psychic, they zero in on one suspect in particular. But for what reason? Host and reporter Matthew Shaer (Over My Dead Body) returns to the scene of the crime, speaks with everyone about a night that still haunts them years later. It’s a series about race and policing, mislaid justice, cutting-edge science, and the kinds of weighty choices that cops and prosecutors make every day -- choices that, once made, are difficult to reverse.

Skeptoid #794: Why You Needn't Worry About the Missing 411

It's no surprise that people do sometimes go missing in the wilderness, including America's national parks. But one notion, called the "Missing 411", claims that inside the parks that number is much higher than it should be, and that the National Park Service covers up these disappearances. Is this true, or does the data say it's just another unfounded conspiracy theory?

Skeptoid #790: Is the Existence of Billionaires Inherently Harmful?

You can hardly turn around these days without hearing someone lecture about how immoral it is that billionaires exist. It's a popular view.
