Swearing associated with honesty, say scientists

Impoliteness and vulgarity are, according to recent recearch, a sign of honesty. Moreover, "the more an individual swears, the more honest they are likely to be."

They first asked a group of 276 participants about their swearing habits, as well as how honest they were in different situations, and found the most honest people were also the heaviest swearers.

They also found that people were much more likely to use swearing as a way to express themselves and their emotions, rather than in an anti-social or harmful way towards others.

In a second study the researchers tested these findings in a more real-life setting, by analysing the status updates of more than 73,000 Facebook users.

They measured for honesty (previous research shows liars prefer to use third-person pronouns than first-person ones and more negative words) and profanity.

Again, they found that honest people were more likely to use profane language.

They ranked swearing and integrity by U.S. state. The sweariest state, Connecticut (52%), was also the second-most most honest (86%). Polite Utah (26%) scored a relatively untrustworthy 65%.

Most-honest Iowa (87%), though, could only maintain a middling swear rate of 40%. Still, the habitual liars of Georgia (49% integrity) sure talk sweet (36% swears). Read the rest

Why people don't return shopping carts

Why do so many people just leave their shopping carts in the parking lot after unloading groceries instead of rolling them to the receptacles? Sure, one answer is laziness. But it's actually more interesting than that, involving what kind of cart user you are and how your motivation aligns with two general categories of social norms. You may be someone who always returns the cart, never returns it, only does so if it's convenience, feels pressure to return it from either a cart attendant or someone waiting to park in the spot where your cart is parked, you have children and they get a kick out of returning it. From Krystal D'Costa's "Anthropology in Practice" column in Scientific American:

Social norms fall into two general categories. There are injunctive norms, which drive our responses based on our perception of how others will interpret our actions. This means that we're inclined to act in certain ways if we think people will think well or think poorly of us. And there are descriptive norms, where our responses are driven by contextual clues. This means we're apt to mimic behaviors of others—so what we see or hear or smell suggests the appropriate/accepted response or behavior that we should display.

Supermarkets can try and guide our behavior with receptacles or cart attendants, but they’re competing with our own self-serving goals, which in this case may be staying dry, keeping an eye on our children, or simply getting home as quickly as possible, and we’re being guided by the ways others behave on top of that.

Why the NYT hired a science denier

The New York Times' new columnist, Bret Stephens, is an everyday conservative: he thinks institutional racism is imaginary, that campus rape is a big lie, and that the "Arab Mind" is "diseased". But these are just opinions, and common ones on the right. It is his anti-science positions, on display in his first fact-mangled column about climate change, that has galvanized disgust.

Much has been said about him, but it is the Times itself that has committed a "jaw-dropping error" and whose warped motives promise that it will be repeated.

Ryan Cooper in The Week directs particular ire at the Times' claim about wanting a diversity of voices, where the agreement of millions is enough to justify a hire. This allows so many possibilities that it betrays the excuse.

If the Times were really committed to ideological diversity in its op-ed page, it would at a minimum hire a conservative who actually supports President Trump, and perhaps even more importantly hire someone with Bernie Sanders-style politics. (Sanders is the most popular politician in the country, yet there are more supporters of torture among columnists of our two major national newspapers than supporters of the senator.)

What we see here is that the neurotic upper-class liberal need for civil debate over important issues stops the moment we reach territory they actually care about. ... A rich, glib, dumb, anti-Trump conservative, on the other hand, can give Upper East Side cocktail parties that frisson of intellectual disputation while conveniently avoiding most of the actually important questions.

Video of a lamb fetus in an artificial womb

Fetal lambs survived for weeks in an experimental artificial womb, and scientists hope that the breakthrough could lead to new treatments for premature babies and perhaps the dreamed-of machine utopia where humans are kept mindlessly writhing in translucent plastic sheaths filled with psuedoamniotic liquid.

Physicians at the Children’s Hospital of Philadelphia placed fetal lambs into the transparent bags and connected their umbilical cords to a machine that oxygenated their blood. The lambs own hearts provided the pumping power.

Eight lambs survived for as long as four weeks inside the devices. The gestational age of the animals was equivalent to a human fetus of 22 or 23 weeks, about the earliest a human baby can be born and expected to survive outside the womb. A full-term baby is born at 40 weeks.

The work of the world's leading nutrition researchers appears to be riddled with statistical errors

Brian Wansink is one of the most-cited nutrition researchers in the world; 30,000 US schools use his advice to design their lunch programs, drawing on studies he's done that show that kids eat more carrots when they're called "X-ray vision carrots" and that putting out fruit bowls improves eating habits, and that smaller plates reduce portion sizes.

Sperm extraction machine yours for $13,000

A Chinese company developed a human sperm extraction machine for use in hospitals and other settings where human sperm may be required on the spot, but where conservative social norms or embarrassment make "while they wait" masturbation a difficult proposition.

The Jiangsu Sanwe Medical Science and Technology Center says their device, which has been sold to clinics in the US, Germany, Russia and France, simulates the temperature and feel of the female sexual organ, and is the most user friendly way of collecting samples for sperm donation or for those needing fertility advice. Jim Drury reports.

Reuters reports about 10,000 of the $13,000 devices are sold annually. The SW-3701 sperm collector's official product page reveals technical parameters, among other things.

It can simulate vaginal environment, through massage, twitching, sucking, vibration, etc., act upon the human penis, which can make semen collection fast and safe. So it is the best clinical equipment of sperm collection.

Premature ejaculation desensitization training

The strong currents impact and rub the glans penis repeatedly in order to reduce the excitability of nerve endings so as to passivate external nerve of glans penis, sulcus coronarius, and the surface of the penis, and regulate the sex nerve center in order to minimize nerve sensitivity, improve ejaculatory threshold to treat premature ejaculation.

New photo of Earth between Saturn's rings can shift your perspective on our reality

That point of light between Saturn's rings is Earth, captured by NASA's Cassini spacecraft on April 12. More about the image here at NASA JPL. It reminds me of the last photo taken by the Voyager I spacecraft before engineers shut off its imaging systems. Carl Sagan had persuaded NASA to turn Voyager I’s cameras back toward the sun on Valentine's Day 1990 and take the first ever "portrait of our solar system" from outside of it. Earth is just a speck in that photo too, a "pale blue dot" as Sagan called it. His beautiful words remind me how a single image can alter one's perspective in an instant:

Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there...
