The Verdict Is In Before The Introduction
People settle a surprising amount about you before you open your mouth, and psychologists have spent decades putting numbers on it. The findings tend to reflect worse on the judges than the judged. Some of what strangers pick up is accurate, while plenty of the rest is stereotype dressed up as intuition. Nobody doing the judging can reliably tell the two apart. Here are 20 things the research says have already been decided.
1. Your Face, Inside A Tenth Of A Second
A 2006 experiment flashed faces at people for 100 milliseconds, about the length of a blink, and asked them to rate trustworthiness. The snap verdicts matched the ratings people gave when allowed to stare for as long as they liked. Parallel experiments got the same result for competence and aggression. All the extra looking time really bought was confidence.
2. Your Shoes
Researchers in 2012 had volunteers photograph the shoes they wore most often, then showed the pictures to strangers. Observers correctly picked up agreeableness and even political leaning from footwear alone. They also got it wrong in a predictable direction, assuming anyone in spotless shoes must be conscientious when the owners' own answers said nothing of the kind. Scuffed told them more than expensive did.
3. Your Height
The number most often quoted comes from a 2004 analysis pooling four long-term studies of around 8,500 people. It put each inch above average height at roughly $789 a year in earnings, which works out near $166,000 across a thirty-year career. The effect was strongest in sales and management, where what the customer thinks decides the outcome. Shorter men took slightly more of the hit than shorter women.
4. The Name At The Top Of Your CV
One of the most cited experiments in economics sent about 5,000 fictional résumés to job adverts in Boston and Chicago in 2004. Applications with white-sounding names drew 50 percent more callbacks than identical ones with Black-sounding names. Strengthening the résumé raised callbacks by 30 percent for the white-sounding names and did almost nothing for the others. The applications went out in pairs, identical but for the name at the top.
5. Six Seconds Of You On Mute
In 1993, judges watched silent clips of teachers they'd never met and rated them on warmth and confidence. Those ratings tracked the students' end-of-term evaluations closely. Cutting the clips from thirty seconds down to six barely dented the accuracy. And no, the judges weren't simply picking out the good-looking ones.
6. Whether You're Wearing Red
Five experiments published in 2008 showed men photographs of the same woman against red, white, grey, green and blue. Red pushed up ratings of attractiveness and desirability, and the men appeared unaware it was happening. Women rating other women showed no such effect. Red left ratings of likeability and intelligence completely alone, so it appears to do one job and no others.
7. How Attractive People Think You Are
An economic analysis from 1994 compared earnings against interviewer ratings of looks. Workers rated below average on appearance earned 5 to 10 percent less than average-looking ones. The bonus at the other end was slightly smaller than the penalty, and the whole effect ran a little stronger for men. The looks ratings came from interviewers, not from the workers themselves.
8. How You Walk
A small 1981 study filmed sixty people on a New York street and asked convicted violent offenders which ones they'd have picked out. The offenders converged on the same handful, and analysts found differences in stride and in how the limbs moved. The sample was tiny and nobody could explain their own choices, so treat the self-defence version of this with suspicion.
9. The Shape Of Your Face
Faces get read for dominance partly on how wide they are relative to their height. Nobody has any idea they're doing the sum. Wider faces draw higher ratings for aggression and for a willingness to exploit others. Whether any of that predicts actual behaviour is contested and the evidence keeps shifting. The perception itself is reliable enough to turn up study after study.
10. Visible Tattoos
One set of hiring experiments found women with visible tattoos were less likely to be hired for supervisory roles and were offered lower starting salaries. Other work from the same period found no penalty at all, and in some labour markets a slight advantage. What the ink means to a stranger appears to depend heavily on which stranger.
11. Whether You're Smiling
Decades of work on how we size each other up keeps boiling down to the same two things. One is whether somebody means well and the other is whether they're any use. A smile shifts the first up sharply and can drag the second down at the same time, which is why a grin plays as warm in one room and lightweight in the next.
12. Your Handshake
Two seconds of contact is apparently plenty. Offer a limp hand and you read as nervous, crush theirs and you read as someone with something to prove. Firmness does track with how capable people take you to be. That's an absurd amount of freight for one gesture.
13. How Much Room You Take Up
Spreading out reads as status and folding inward reads as deference, which observers pick up almost instantly. The famous business about standing in a wide stance to change your own hormones did not survive replication. What did survive is the part about other people, who reliably rate expansive bodies as more dominant whatever is happening inside them. Observers make that call in well under a second.
14. How Long You Hold Eye Contact
There's a fairly narrow window that reads as confident, and both sides of it are penalised. Too little gets scored as evasive and too much as hostile or strange. The acceptable duration shifts by culture. A perfectly ordinary amount of looking in one country is rude in another. Nobody announces where the line sits.
15. Your Teeth
Straightness and colour shape how attractive a face is judged to be, and from there what people assume about the money behind it. Orthodontics is expensive and unevenly handed out, so teeth end up being a fairly blunt readout of what your parents could pay for. Strangers read the signal constantly and nobody involved would describe it as a judgment about class.
16. Your Haircut
Grooming turns up repeatedly in the appearance-and-earnings literature as a separate thing from attractiveness. Some analyses find the grooming effect does most of the work for women that raw looks are usually credited with. Interviewers rate the better-groomed version of a candidate higher. It's also the one item on this list you can change by Thursday.

17. Your Watch
Visible status symbols shape how people judge someone's competence and income before they know anything about them. The item doesn't even have to be genuine. A convincing fake can make the same first impression. Recognizable logos matter more than actual quality because the signal needs to register at a glance. The effect wears off once people have something more substantial to judge.
18. Your Profile Photo
The same face photographed twice produces measurably different judgments depending on angle and lighting. People pick their own best photo poorly, and strangers choose a better one for them than they choose for themselves. Whichever image lands in front of a recruiter is doing a job you can't supervise.
19. How Close You Stand
Personal space has a measurable radius, and crossing it registers as either intimacy or threat with nothing much in between. The distance varies by culture and by how crowded the room already is. It shrinks on a packed train and nobody objects. Standing a little too close is among the quickest routes to being read as untrustworthy by someone who couldn't tell you why.
20. Your Weight
Field experiments on hiring consistently find heavier applicants are called back less often and offered less when they are. The effect is larger for women and shows up in roles with no physical component whatsoever. Identical applications attached to heavier photographs do measurably worse. It says nothing about the applicants and a fair amount about the people doing the hiring.
