👀 Just 100 milliseconds...
Make yourself more likable, trustworthy, confident, successful, and influential — backed by science.

Readtime: 2.5 minutes
In just one tenth of a second…
We make dozens of judgements about a stranger’s face.
…how attractive, likable, approachable, trustworthy, confident, competent, successful, influential, and dominant the person is.
Psychologists Janine Willis and Alexander Todorov from Princeton did a series of experiments in 2006 to figure this out.
They also found that looking at a face for longer doesn’t significantly change our impressions.
Other studies have found that various things influence how people see us — our expressions, eyes, jawline, posture, angle, lighting, and clothing.

Let’s look at some of the findings:
I’ve condensed a bunch of findings for you:
Do:
 ✅ Big natural laugh or smile showing your teeth
→ more likable and approachable 
 ✅ Smiling eyes (i.e. a natural smile; the Duchenne smile)
→ more sincere and trustworthy 
 ✅ Squint your eyes slightly
→ more confident and comfortable (wide eyes show fear) 
 ✅ Define your jawline with a shadow under it
→ more likable and competent 
 ✅ Head-and-shoulders or head-to-waist photo
→ more competent and influential 
 ✅ Wear nice clothes (especially dark suit and light button shirt) 
→ more influential with a higher status 
 ✅ Make your photo asymmetrical (e.g. looking away, rule of thirds)
→ more interesting and memorable 
 ✅ Look where you want people to look
→ points the viewer’s eye (e.g. to a headline or button) 
Don’t:
 ❌ Obscure your eyes with sunglasses
→ less likable 
 ❌ Obscure your eyes with hair, glare, shadow, etc.
→ less competent and influential 
 ❌ Zoom in for a close-up of your face
→ less likable 
 ❌ Zoom out to show your full body
→ less competent and influential 
Interesting note: Black and white photos didn’t have any significant effect — positive or negative. 
Of course, it all depends on YOU…
Who’s your audience?
What’s your personality?
Maybe the teeth-smiling suit-wearing head-and-shoulder thing just isn’t for you!
…and that’s totally fine.
Your picture has to be consistent with your brand.
From my own experience in positioning and identity…
- Presenting yourself differently from everyone else makes you more noticeable and memorable. 
Now, let’s look at some excellent examples in the wild…

P.S. OK Cupid found that men may actually benefit from looking away from camera — I wonder if it makes them seem less dominant and more approachable 🤷♂️
