Super-Nice People May Be More Likely to Betray You

When it comes to people, it’s the sickly-sweet ones you have to watch out for. That’s the conclusion of a study by a team of linguists and computer scientists, who analyzed the conversational patterns of people playing an online strategy game. 

As writer Rachel Ehrenberg explains in Science News, interpersonal conflicts like betrayal can be very difficult to study. It’s not as if you can bring two people into the lab, instruct one to backstab the other, and draw reasonable conclusions from their behavior while they’re being watched. “We all know betrayal exists,” computer scientist Cristian Danescu-Niculescu-Mizil told Ehrenberg. “But finding relevant data is really hard.”

So when Danescu-Niculescu-Mizil heard about the game Diplomacy, a lightbulb went off in his head. In this strategy game, which was invented during the Cold War, players compete to gain territories not with weapons or armies, but with words. The game has maintained a dedicated fanbase for more than half a century. Today, most games of Diplomacy are played online, with players conducting their negotiations, alliances, treaties, manipulations, coups, and, of course, betrayal from behind their keyboards. 

Danescu-Niculescu-Mizil realized that the transcripts of these conversations could be a data goldmine. He joined forces with fellow computer scientist (and diehard Diplomacy fan) Jordan Boyd-Graber, as well as computational linguist Vlad Niculae and data mining expert Srijan Kumar. The researchers compiled 145,000 messages between players and analyzed them in the hopes of finding what they called “linguistic harbingers of betrayal.” 

They found them, all right. “Sudden changes in the balance of certain conversational attributes—such as positive sentiment, politeness, or focus on future planning—signal impending betrayal,” they wrote in a report. In other words, if somebody starts being really, really polite or eager all of a sudden, it might be time to start edging away. 

An example, taken from a game transcript: 

GERMANY: Can I suggest you move your armies east and then I will support you? Then next year you move [there] and dismantle Turkey. I will deal with England and France, you take out Italy. 

AUSTRIA: Sounds like a perfect plan! Happy to follow through. And—thank you Bruder! 

“Immediately after this exchange,” the researchers noted, “Austria invaded German territory.”

It is important to keep in mind this study is only looking at players in a betrayal-centric game. It’s possible that the really super-friendly person in your office is legitimately super-friendly and not out to get you. We’ll have to wait on more research to find out for sure.

Danescu-Niculescu-Mizil and his colleagues presented their findings last summer at the Annual Meeting of the Society for Computational Linguistics. The acknowledgments section of their report [PDF] was both topical and pointed: “This work is dedicated to all those who betrayed us.”

Language App Can Now Help You Learn High Valyrian From Game of Thrones
Original image
HBO

The language-learning app Duolingo is a helpful tool for preparing for a Japanese vacation or brushing up on your high-school Spanish. But soon there will a new reason to download the app: In addition to the “real” languages it teaches, Duolingo will be offering High Valyrian to enhance your Game of Thrones-watching experience, SFGate reports.

In the acclaimed HBO series, High Valyrian is the dialect spoken by Daenerys Targaryen, one of the last surviving descendants of Old Valyria. As is the case with Dothraki, Valyrian was invented by conglanger (language constructor) David J. Peterson. He thoughtfully composed both languages to mimic organic linguistics, so that viewers could learn to speak the languages at home.

Now Game of Thrones fans will be able teach themselves High Valyrian without studying a digital dictionary. A beta version of Duolingo’s High Valyrian lessons will launch for web browsers on July 13 and eventually make its way to the iOS and Android apps.

The seventh season of Game of Thrones premieres July 16 on HBO. While you may not be able to reach Daenerys-level fluency by then, you’ll have plenty of time to learn the basics, like Valar morghulis, or ”All men must die.”

15 Words That Aren’t As Straightforward As They Look
Original image

There’s an etymological old wives’ tale that suggests the “step” in stepmother and stepfather comes from the fact that they're added onto genealogical charts one step away from your biological ones. Unfortunately, it’s completely untrue.

Despite appearances, the “step” in these words stems from an Old English term, steop, which was once used to indicate loss or bereavement. Way back then, “stepchild” or steopcild meant orphan, not just the offspring of a second spouse.

Here are 15 more words whose true origins and meanings aren’t quite as straightforward as they seem.

1. THE “QUICK” IN QUICKSAND DOESN’T MEAN FAST.

Despite what you might think about the stuff sucking people to their deaths before they have time to escape, this word isn’t a synonym for speedy. It doesn’t mean “fast” in the word quicksilver—an old name for mercury—either. Instead, these adjectives both mean “alive” or “living,” a reference to the moving, animated ground in a patch of quicksand, and to the fact that quicksilver, as a liquid, can move and be poured.

2. THE “LOLLI” IN LOLLIPOP DOESN’T MEAN LOLLING.

The old story that the word refers to popsicles and ice-lollies that droop as they melt just isn’t true. In fact, this lolly is an Old English dialect term for the tongue.

3. THE “MID” IN MIDWIFE DOESN’T MEAN MIDDLE.

For that matter, the “wife” in midwife doesn’t mean, well, wife. The word wife originally meant “woman,” while mid stood in for “with”—making a midwife a woman who is literally with a woman as she gives birth.

4. THE “WILDER” IN WILDERNESS DOESN’T MEAN WILD.

At least not in the sense of the “woods and wilds.” This wilder is a corruption of the Old English wild deor, meaning wild deer or animal—which you will definitely find in the wilderness.

5. THE “CUT” IN CUTLET DOESN’T MEAN TRIMMED.

This prefix has nothing to do with cutlets being “cut” from a larger joint of meat. In this case, cutlet descends from the French word costelette, meaning little rib.

6. THE “BEL” IN BELFRY DOESN’T MEAN BELL.

A belfry isn’t necessarily a bell tower. The original belfry was actually a mobile siege tower that could be wheeled up to castles and town walls by invading armies to gain access from outside. In that sense, the word derives from bercfrit, the old Germanic name for this piece of equipment.

7. THE “HAM” IN HAMBURGER DOESN’T MEAN MEAT.

The beginning of the word has nothing to do with meat of any kind. You probably know this one already: Hamburgers are people or things that come from Hamburg, Germany. The hamburglar, on the other hand, comes from Des Plaines, Illinois.

8. THE “JERUSALEM” IN JERUSALEM ARTICHOKE DOESN’T REFER TO THE CITY.

The adjective for this unassuming tuber is a corruption of girasole, the Italian word for sunflower. The Jerusalem artichoke is not an artichoke—it’s actually a member of the sunflower family. It's also called a sunchoke or sunroot.

9. THE “PIGGY” IN PIGGYBACK DOESN’T MEAN PIG.

Piggyback is believed to be a corruption of pick-a-pack or pick-pack—a 16th-century expression for carrying something on your shoulders. It might derive from the old use of pick to mean “pitch,” and pack, meaning a sack or satchel.

10. THE “SAND” IN SANDBLIND DOESN’T REFER TO THE BEACH.

Sandblind is a 15th-century word, seldom encountered today outside of literature and poetry, for being half-blind. It is often said to allude to the poor visibility experienced during dust storms and sand storms. But it’s simpler than that: sandblind derives from its Old English equivalent samblind, the “sam” of which means the same as “semi” does today.

11. THE “CURRY” IN CURRY FAVOR DOESN’T MEAN STEW.

There’s an old myth that currying favor with someone alludes to slowly working your way into their social circle, just as the flavors in a curry or stew mingle together as it cooks. Instead, the true story behind this one is even more peculiar. In this case, curry derives from a Middle English word meaning “to groom a horse,” while favor is a corruption of Fauvel, the name of a chestnut-colored horse that appeared in an old French poem and folktale about a horse that wanted to usurp its master and take over his kingdom. In the tale, Fauvel succeeds in his quest and ends the story being fawned over and “curried” by all the obsequious members of his master’s court. Currying favor literally means “sycophantically grooming a chestnut horse.”

12. THE “FACE” IN SHAMEFACED DOESN’T MEAN VISAGE.

Shamefaced was originally shamefast, with -fast in this sense meaning fixed or constant, as it does in steadfast or stuck fast. Presumably the word changed over time because the shame of a shamefaced person can be seen in his or her expression.

13. THE “CHOCK” IN CHOCK-FULL DOESN’T MEAN A WEDGE OR BLOCK.

Being chock-full has nothing to do with being rammed as tightly as a chock is below a door or the wheels of a vehicle. Instead, chock in this context is derived from choke, in the sense of something being suffocatingly crammed or crowded.

14. THE “D” IN D-DAY DOESN’T STAND FOR DISEMBARKATION.

It also doesn’t mean deliverance, Deutschland, doomsday, decision, or any of the other D-words popular history might have you believe. In fact, D doesn’t stand for anything at all: just like (albeit less common) expressions like H-hour, D-Day was just an alliterative placeholder used during the planning of the Normandy landings for the unspecified day on which the operation would take place. As further evidence, the earliest use of the term comes from 1918, a full 26 years before Allied troops stormed the beaches. The French name for D-Day, by the way, is J-Jour.

15. THE “GOOD” IN GOODBYE DOESN’T MEAN GOOD.

Goodbye is a contraction of “God be with you,” an expression of departure or best wishes in use in English from the medieval period. As the phrase simplified over time, “God” drifted toward “good” in other similar expression likes good day and good morning. By the late 16th century, we were left with the word we use today.
