Online Daters Tend to Be Interested in Partners 25 Percent More Desirable Than They Are

Online dating may not bring out the best in people (as anyone who’s been ghosted can attest) but it does bring out our optimistic side. A new study suggests that people tend to reach out to fellow online daters who are approximately 25 percent more attractive than they are, according to The Washington Post.

The study, published in the journal Science Advances, looked at online dating messaging behavior from heterosexual men and women in four different U.S. cities. Researchers analyzed how many messages people sent and received in January 2014, how long those messages were, and how many messages went unanswered.

They examined daters in New York City, Chicago, Seattle, and Boston, including age, ethnicity, and education of the users in their analysis, but kept the profiles anonymous and did not read the messages themselves. (The researchers don’t name the particular site they got their data from, merely describing it as a “popular, free online dating service.” From the details, it sounds a lot like OkCupid or a very similar site: one that allows users to answer open-ended essay questions and list attributes like their religion and body type on their profiles.)

To quantify how desirable a person was, the researchers looked at the hard numbers—how many messages someone received, and how the senders themselves ranked on the desirability scale.

Both men and women tend to aim high, messaging someone more desirable than themselves by about 25 percent, on average. For the most part, users didn’t contact people who ranked lower than themselves on the desirability scale. When they did contact people who were hotter, daters tended to write much longer messages than they did when they contacted someone on their own level, so to speak—sometimes up to twice as long. Women tended to use more "positive" words (like "good" and "happy") when they were writing to hotter dudes, while men actually used fewer positive words when talking to hotter ladies. Men in Seattle sent the longest messages, perhaps because of the city’s makeup—in some populations, there are twice as many men there as women, so heterosexual men face a lot of competition. Although wordy messages in Seattle did have a slightly higher response rate, in other cities, the extra time spent typing out missives didn’t pay off. Given that those messages weren’t any likelier to get a response than a short note, the researchers write that the “effort put into writing longer or more positive messages may be wasted.”

The data also showed how desirability in online dating can be influenced by attributes like age, education level, and ethnicity. For instance, at least as far as averages go, older men tended to be viewed as more desirable than younger men until they hit 50. Women’s scores peaked when they were 18 years old (the youngest age when you can join the site) and decreased until age 60.

Even if you aren’t in the pool of the most attractive users, sometimes, aiming high can pay off. “Even though the response rate is low, our analysis shows that 21 percent of people who engage in this aspirational behavior do get replies from a mate who is out of their league, so perseverance pays off,” co-author Elizabeth Bruch explained in a press release.

Can You Tell an Author’s Identity By Looking at Punctuation Alone? A Study Just Found Out.

In 2016, neuroscientist Adam J Calhoun wondered what his favorite books would look like if he removed the words and left nothing but the punctuation. The result was a stunning—and surprisingly beautiful—visual stream of commas, question marks, semicolons, em-dashes, and periods.

Recently, Calhoun’s inquiry piqued the interest of researchers in the United Kingdom, who wondered if it was possible to identify an author from his or her punctuation alone.

For decades, linguists have been able to use the quirks of written texts to pinpoint the author. The process, called stylometric analysis or stylometry, has dozens of legal and academic applications, helping researchers authenticate anonymous works of literature and even nab criminals like the Unabomber. But it usually focuses on an author's word choices and grammar or the length of his or her sentences. Until now, punctuation has been largely ignored.

But according to a recent paper led by Alexandra N. M. Darmon of the Oxford Centre for Industrial and Applied Mathematics, an author’s use of punctuation can be extremely revealing. Darmon’s team assembled nearly 15,000 documents from 651 different authors and “de-worded” each text. “Is it possible to distinguish literary genres based on their punctuation sequences?” the researchers asked. “Do the punctuation styles of authors evolve over time?”

Apparently, yes. The researchers crafted mathematical formulas that could identify individual authors with 72 percent accuracy. Their ability to detect a specific genre—from horror to philosophy to detective fiction—was accurate more than half the time, clocking in at a 65 percent success rate.

The results, published on the preprint server SocArXiv, also revealed how punctuation style has evolved. The researchers found that “the use of quotation marks and periods has increased over time (at least in our [sample]) but that the use of commas has decreased over time. Less noticeably, the use of semicolons has also decreased over time.”

You probably don’t need to develop a powerful algorithm to figure that last bit out—you just have to crack open something by Dickens.

What Happens to Your Body If You Die in Space?

The coming decades should bring about a number of developments when it comes to blasting people into orbit and beyond. Private space travel continues to progress, with Elon Musk and Richard Branson championing civilian exploration. Professional astronauts continue to dock at the International Space Station (ISS) for scientific research. By the 2040s, human colonists could be making the grueling journey to Mars.

With increased opportunities comes the increased potential for misadventure. Though only 18 people have died since the emergence of intragalactic travel in the 20th century, taking more frequent risks may mean that coroners will have to list "space" as the site of death in the future. But since it's rare to find a working astronaut in compromised health or of an advanced age, how will most potential casualties in space meet their maker?

Popular Science posed this question to Chris Hadfield, the former commander of the ISS. According to Hadfield, spacewalks—a slight misnomer for the gravity-free floating that astronauts engage in outside of spacecraft—might be one potential danger. Tiny meteorites could slice through their protective suits, which provide oxygen and shelter from extreme temperatures. Within 10 seconds, water in their skin and blood would vaporize and their body would fill with air: Dissolved nitrogen near the skin would form bubbles, blowing them up like a dollar-store balloon to twice their normal size. Within 15 seconds, they would lose consciousness. Within 30 seconds, their lungs would collapse and they'd be paralyzed. The good news? Death by asphyxiation or decompression would happen before their body freezes, since heat leaves the body slowly in a vacuum.

This morbid scene would then have to be dealt with by the accompanying crew. According to Popular Science, NASA has no official policy for handling a corpse, but Hadfield said ISS training does touch on the possibility. As he explained it, astronauts would have to handle the the body as a biohazard and figure out their storage options, since there's really no prepared area for that. To cope with both problems, a commander would likely recommend the body be kept inside a pressurized suit and taken someplace cold—like where garbage is stored to minimize the smell.

If that sounds less than regal, NASA agrees. The company has explored the business of space body disposal before, and one proposition involves freeze-drying the stiff with liquid nitrogen (or simply the cold vacuum of space) so it can be broken up into tiny pieces of frozen tissue, which would occupy only a fraction of the real estate that a full-sized body would.

Why not eject a body, like Captain Kirk and his crew were forced to do with the allegedly dead Spock in 1982's Star Trek II: The Wrath of Khan? Bodies jettisoned into space without a rocket to change their trajectory would likely fall into the wake of the spacecraft. If enough people died on a long trip, it would create a kind of inverted funeral procession.

Even if safely landed on another planet, an astronaut's options don't necessarily improve. On Mars, cremation would likely be necessary to destroy any Earth-borne bacteria that would flourish on a buried body.

Like most everything we take for granted on Earth—eating, moving, and even pooping—it may be a long time before dying in space becomes dignified.
