Éclat for the smartest girl in the room
Today: the study where students swore their thesis would take 34 days and it took 55, the corduroy comeback hiding in plain sight, the secret yellow that leaves keep all summer, crows that remember a face for years, why your own name cuts through a noisy room, and the truth about “left-brained” people — plus a French phrase for charm you can’t explain and the case of the owl that nobody described.

Why Your “One Hour” Essay Always Takes Three
In the early 1990s, psychologists asked 37 students how long their senior thesis would take. The average guess was 33.9 days. The students were also asked for a worst-case scenario, “if everything went as poorly as it possibly could,” and that guess averaged 48.6 days. The real average? 55.5 days, and only about 30% finished when they had predicted. Even their worst-case plan was too optimistic. Psychologists Roger Buehler, Dale Griffin and Michael Ross called this the “planning fallacy,” a name that Daniel Kahneman and Amos Tversky had coined years earlier. The trick is that we plan by picturing the smooth version of the future, and our brain quietly deletes the phone calls, the printer jams and the sudden need for a snack.

Why it's cool The fix is not trying harder; it is asking how long similar tasks took you last time, which beats your imagination almost every time.
Read moreCorduroy Is Having a Moment, and the Texture Is the Point
Look closely at fall’s trousers and jackets and you will see ridges running down the fabric. Those ridges are called wales, and the wider they are, the more retro the cord feels. The trend works because so much of fashion lately has been smooth and glossy, so a fabric you want to touch feels like a small rebellion. Runways have pushed it in 70s-style flares, wide legs and slouchy matching sets, in warm shades like chocolate brown, beige and burgundy. To wear it without looking like a costume, let the cord be the loud part and keep the rest simple: a plain knit, clean sneakers, one texture doing the talking.

Read moreThe Yellow Was Hiding in the Leaf All Summer
A leaf is not secretly turning yellow in autumn; it was yellow all along. Carotenoids, the pigments that make yellows and oranges, are present all year, but chlorophyll, the green pigment that runs photosynthesis, is so abundant in summer that it covers them up. As days shorten, the tree stops making chlorophyll and the old green breaks down, so the hidden colors appear. Reds and purples are different: those anthocyanins are newly made in autumn from sugars trapped in the leaf, which is why sunny days and cool nights give the most dramatic reds.
Tell someone Autumn yellow isn’t a new color; it’s the leaf’s original color finally being allowed to show up, while the reds are brand-new pigments made on purpose.
Crows Remember a Face, and They Hold Grudges
Researchers at the University of Washington led by John Marzluff wanted to know if crows can tell individual humans apart. They wore a rubber caveman mask while trapping and banding seven crows on campus, and wore a different mask as the harmless control. Years of testing later, the crows scolded the “dangerous” mask far more than before, even when the person wore a hat or held the mask upside down. A mask can’t be a clue about size or walk, which means the birds were picking out the face itself.
Tell someone If you are rude to a crow, it may remember your face, so be nice to the birds on your street.
Why Your Name Cuts Through a Noisy Room
You are in a loud cafeteria, locked into one conversation, and somewhere across the room someone says your name and your head snaps up. Psychologists call the broader pattern the “cocktail party effect,” first studied by Colin Cherry in 1953. In a 1959 experiment, Neville Moray had people repeat one message aloud in one ear while their own names were slipped into the other ear that they were told to ignore. About a third noticed. Your brain isn’t ignoring the background; it’s quietly filtering it for what matters most to you.
Tell someone Your brain is secretly monitoring the conversations you’re ignoring, and your name is on its permanent watch list.
Are You “Left-Brained” or “Right-Brained”? Not Really
The idea is everywhere: left-brained people are logical and orderly, right-brained people are creative and intuitive. It’s true that some functions lean to one side, such as language for most people. But in a 2013 University of Utah study published in PLOS ONE, researchers analysed brain scans from more than 1,000 people aged 7 to 29. They found no sign that people use one hemisphere’s network more than the other. Stronger connections vary region by region, not as one dominant side. Your brain works as one connected team, and creative and logical thinking use both sides.
Fine print This is about the “personality” claim, not about lateralization itself: language and attention really do rely more on one side, and brain injuries can affect each side differently. The scan study also can’t tell us about every trait. The simple quiz label is the myth.
je ne sais quoi
zhuh nuh say KWAH · noun phrase
literally “I don’t know what”; an appealing quality that is hard to name or explain.
« Elle a ce je ne sais quoi qui fait que tout le monde l’écoute. »
“She has that certain something that makes everyone listen to her.”
English borrowed this phrase straight from French, and it’s the perfect compliment when someone’s charm resists a list of reasons. Use it with a smile for a person, a song or a perfectly worn jacket. Say it too often and it starts to sound like a perfume ad, so save it for when you truly mean it.
The Case of the Brass Owl
The robotics club’s lucky brass owl vanished from the trophy room’s locked display case between 3:00 and 3:30pm. Four club members had a key: Dana, Leo, Mira and Jun. At 3:35, their teacher, Ms. Okafor, covered the empty case with a cloth and told each of them in person, one at a time, only this: “Something has gone missing from the trophy room.” She named no object and sent no message about it. Leo said he was in the lab the whole time and hoped it wasn’t the laptop. Mira said she had been at practice and would help search. Jun shrugged and asked what it was. Dana sighed and said, “Honestly, who steals a tiny brass owl?”
Who is the thief, and which line gave it away?
Reveal the answer
Dana is the thief. Ms. Okafor never told anyone what was missing, and nothing had been posted, so nobody but the person who took it could have known it was a small brass owl. Leo guessed a laptop and Jun asked, which is how innocent people sound.
Why did the chemist break up with the autumn leaf? Every time things got serious, it showed its true colors.
I’m not procrastinating on my essay; I’m just giving the planning fallacy time to settle in. It will definitely take an hour. It said so the last eleven times.
Why was the “left-brain, right-brain” theory never invited to parties? It always split the room, and then turned out to be mostly made up.
Write an “If–Then” Plan, Because Intentions Alone Are Weak
Wanting to do something and actually doing it are surprisingly far apart, and the planning fallacy shows why: a vague plan leaves too many chances to drift. Psychologist Peter Gollwitzer studied “implementation intentions,” plans written as “If X happens, then I will do Y.” A 2006 review by Gollwitzer and Paschal Sheeran combined 94 independent tests and found a medium-to-large average boost in reaching goals (d = 0.65). It works because you pre-decide the moment, so the cue itself triggers the action instead of asking your willpower to show up. Keep the plan small and specific, and name a real time or place.
Try it today Pick one task you keep putting off and write it as one sentence: “If it’s 7:00pm and I’ve finished dinner, then I will open the document and write for ten minutes.”

Cecilia Payne
In 1925, at 25, she showed in her Harvard PhD thesis that stars are made mostly of hydrogen and helium. The leading expert of the time, Henry Norris Russell, talked her into calling her own result “almost certainly not real,” but in 1929 he reached the same conclusion himself and cited her work. Astronomer Otto Struve later called her thesis “the most brilliant PhD thesis ever written in astronomy.” More →
