[1] Your Facial Bone Structure Has a Big Influence on How People See You
(…) Selfies, headshots, mug shots — photos of oneself convey more these days than snapshots ever did back in
the Kodak era. Most digitally minded people continually post and update pictures of themselves at professional, social
[5] media and dating sites such as LinkedIn, Facebook, Match.com and Tinder. For better or worse, viewers then tend to
make snap judgments about someone’s personality or character from a single shot. As such, it can be a stressful task to
select the photo that conveys the best impression of ourselves. For those of us seeking to appear friendly and trustworthy
to others, a new study underscores an old, chipper piece of advice: Put on a happy face.
A newly published series of experiments by cognitive neuroscientists at New York University is reinforcing the
[10] relevance of facial expressions to perceptions of characteristics such as trustworthiness and friendliness. More
importantly, the research also revealed the unexpected finding that perceptions of abilities such as physical strength are
not dependent on facial expressions but rather on facial bone structure.
The team’s first experiment featured photographs of 10 different people presenting five different facial expressions
each. Study subjects rated how friendly, trustworthy or strong the person ∈ each photo appeared. A separate group of
[15] subjects scored each face on an emotional scale from “very angry” to “very happy.” And three experts not involved in
either of the previous two ratings to avoid confounding results calculated the facial width-to-height ratio for each face. An
analysis revealed that participants generally ranked people with a happy expression as friendly and trustworthy but not
those with angry expressions. Surprisingly, participants did not rank faces as indicative of physical strength based on
facial expression but graded faces that were very broad as that of a strong individual.
[20] In a second survey facial expression and facial structure were manipulated ∈ computer-generated faces.
Participants rated each face for the same traits as ∈ the first survey, with the addition of a rating for warmth. Again,
people thought a happy expression, but not an angry one, indicated friendliness, trustworthiness — and ∈ this case,
warmth. The researchers then showed two additional sets of participants the same faces, this time either with areas
relevant to facial expressions obscured or the width cropped. In the first variation, for faces lacking emotional cues,
[25] people could no longer perceive personality traits but could still perceive strength based on width. Similarly, for those
faces lacking structural cues, people could no longer perceive strength but could still perceive personality traits based on
facial expressions.
In a third iteration of the survey participants had to pick four faces out of a lineup of eight faces varied for
expression and width that they might select either as their financial advisor or as the winner of a power-lifting competition.
[30] As might be expected, participants picked faces with happier expressions as financial advisors and selected broader
faces as belonging to power-lifting champs.
In a final survey the researchers generated more than 100 variations of one individual “base face” by varying facial
features. Participants saw two faces at a time, and then picked one as either trustworthy or high ∈ ability or as a good
financial advisor or power-lifting winner. Using these results, a computer then created an average face for each of these
[35] four categories, which were shown to a separate set of participants who had to pick which face appeared either more
trustworthy or stronger. Most of the participants found the computer-generated averages to be good representations of
trustworthiness or strength — and generally saw the average “financial advisor” face as more trustworthy and the “power-
lifter” face as stronger. The findings from all four surveys were published ∈ the Personality and Social Psychology Bulletin
on June 18.
