In one of the many wonderful moments in Think Like a Freak, Steven Levitt and Stephen Dubner ask the question: Who is easier to fool—kids or adults? The obvious answer, of course, is kids. The cliché is about taking candy from a baby, not a grown man. But instead of accepting conventional wisdom as fact, the two sit down with the magician Alex Stone—someone in the business of fooling people—and ask him what he thinks. And his answer? Adults.
Stone gave the example of the staple of magic tricks, the “double lift,” where two cards are presented as one. It’s how a magician can seemingly bury a card that you have selected at random and then miraculously retrieve it. Stone has done the double lift countless times in his career, and he says it is kids—overwhelmingly—who see through it. Why? The magician’s job is to present a series of cues—to guide the attention of his audience—and adults are really good at following cues and paying attention. Kids aren’t. Their gaze wanders. Adults have a set of expectations and assumptions about the way the world works, which makes them vulnerable to a profession that tries to exploit those expectations and assumptions. Kids don’t know enough to be exploited. Kids are more curious. They don’t overthink problems; they’re more likely to understand that the basis of the trick is something really, really simple. And most of all—and this is my favorite—kids are shorter than adults, so they quite literally see the trick from a different and more revealing angle.

Our latest podcast compared the costs of marijuana use to the costs of alcohol use. A new study in the current issue of The Journal of Neuroscience argues that casual use of marijuana affects the developing brain. Jason Koebler, writing for Vice, summarizes the findings:
High-resolution MRI scans of the brains of adults between the ages of 18-25 who reported smoking weed at least once a week were structurally different than a control group: They showed greater grey matter density in the left amygdala, an area of the brain associated with addiction and showed alterations in the hypothalamus and subcallosal cortex. The study also notes that marijuana use “may be associated with a disruption of neural organization.” The more weed a person reported smoking, the more altered their brain appeared, according to the Northwestern University and Harvard Medical School study, which was published in the Journal of Neuroscience.
The finding already has the study’s authors calling for states to reconsider legalizing the drug. Hans Breiter, the lead author, said he’s “developed a severe worry about whether we should be allowing anybody under age 30 to use pot unless they have a terminal illness and need it for pain.

We have blogged and written extensively about the gender pay gap, much of which is not attributable to discrimination, as is commonly invoked. President Obama has taken up the cause; he recently signed two executive orders aimed at closing the gap. Business Insider recently posted a state-by-state breakdown of the gender wage gap. It is interesting to look at but keep in mind the non-discriminatory factors that contribute to the gap, and therefore consider these numbers with some skepticism:
Wyoming has the biggest pay gap — the median male full-time worker made $51,932, and the median female full-time worker made $33,152. The male worker thus made 56.6% more than the female worker.
Washington, D.C. had the smallest gap — there, men make 11.0% more than women. Among the states, Maryland and Nevada had the smallest gaps, both at 17.2%.

BBC News reports the story of Arunachalam Muruganantham, a school dropout in rural India who invented a technology that could vastly improve reproductive health for women. The user-friendly technology relies on simple machines to produce sanitary pads at a low cost, a boon for women unwilling or unable to pay for the higher-priced sanitary pads in stores.

[Muruganantham] discovered that hardly any women in the surrounding villages used sanitary pads – fewer than one in 10. His findings were echoed by a 2011 survey by AC Nielsen, commissioned by the Indian government, which found that only 12% of women across India use sanitary pads.
Muruganantham says that in rural areas, the take-up is far less than that. He was shocked to learn that women don’t just use old rags, but other unhygienic substances such as sand, sawdust, leaves and even ash.
Women who do use cloths are often too embarrassed to dry them in the sun, which means they don’t get disinfected. Approximately 70% of all reproductive diseases in India are caused by poor menstrual hygiene – it can also affect maternal mortality.
