11 Tiny Habits That Reveal a Lot About Your Personality, According to Science

12 physical traits that reveal your personality (according to science)

We tend to make a lot of assumptions about each other the way people walk. For example, we associate looser gaits with extroversion and adventurousness, and see clipped walkers as more neurotic.

But those assumptions are generally wrong.

The only thing that research suggests we can accurately predict from someone's walk is how vulnerable they feel. In one 2013 study, researchers asked inmates to watch video clips of different people walking and judge which were most vulnerable to victimization.

Results showed that inmates who scored higher on measures of psychopathy were more ly to pick out walkers who had been victimized in the past. When asked why they made their judgments, many said they could tell by the way the person walked.

Psychologist James Pennebaker has spent years studying function words, such as “the,” “this,” and “I.”

He's found that the way we use these words can provide clues to our gender, age, mental health status, and whether we're romantically interested in our conversation partner.

For example, Pennebaker and colleagues listened to recordings of speed dates between men and women and found that when couples used similar language styles–specifically, when they used similar function words–they were more ly to go on a date.

As NPR reports, that's not because the couples were more similar to begin with–the researchers observed this phenomenon even among people who were very different. Instead, it's probably because we shift our language when we're interested in someone.

Your emails may reveal whether you're an extrovert or a narcissist

Look closer at the next email you receive–it could provide some insight into the sender's personality traits.

Writing in Fast Company, psychologist Tomas Chamorro-Premuzic says that extroverts are more ly to talk about fun-related things, music and parties. People with lower emotional intelligence tend to use emotional and negative words, such as “depressed” and “angry.”

Perhaps unsurprisingly, narcissists generally talk about themselves, using words such as “I,” “me,” and “mine.”

Your punctuality may reveal whether you're Type A or B

Just because your friend is always late doesn't necessarily mean he's inconsiderate.

One study found that those who are chronically late are probably more laid-back, “Type B” individuals.

Meanwhile, psychologist Linda Sapadin told The Atlantic that she sees four types of personalities who are always late (you can be a combination of all four).

The perfectionist won't leave the house until everything is in order. The crisis maker gets a high from racing to meet the deadline. The defier is rebelling against authority and societal norms. The dreamer is overly optimistic about how much they can get done in a certain amount of time.

Your nervous tics may reveal whether you're a perfectionist

There's a reason why some people engage in what scientists call “body-focused repetitive behaviors” (BFRB), biting their nails, pulling their hair, or picking their skin.

In one 2015 study, researchers filmed people while they were in a situation that was stressful, frustrating, relaxing, or boring. Results showed that those who scored high on measures of perfectionism were more ly to display these behaviors, especially in the stressful, frustrating, and boring conditions.

As Scientific American reports, boredom may be a trigger for BFRB because those behaviors may be a way for perfectionists to feel better by doing something instead of nothing.

Your addiction to your phone may reveal your emotional stability

Most of us are guilty of checking our phones when we're waiting in line at the grocery store, commuting to work, or even talking to friends.

Recent research reveals what it means if you're constantly staring at that screen. The 2015 study measured cell phone “addiction” by asking people how much they agreed with statements such as “I get agitated when my cell phone is not in sight” and “I spend more time than I should on my cell phone.”

Results showed that emotional instability was a key predictor of cell-phone addiction.

Interestingly, the study also found that introverts–people who expressed feelings of shyness and bashfulness–were less ly to be addicted to their phones.

The way you organize your inbox may reveal how controlling you are

Whether you're an inbox hero or you don't mind watching your “unread” count tick up to 10,001, the way you maintain your email inbox may say a lot about your personality.

Those who file and delete emails as soon as they receive them may have a greater need for control and order in their lives.

Those who save emails–meaning they read them but don't delete them–may be perfectionists, who think they'll get around to addressing those messages eventually.

Lastly, those who leave emails unread, without filing or deleting them, may feel overwhelmed. Alternatively, they may also be smart because they recognize that reading those emails isn't helping them make substantive progress.

Your selfie style may reveal how open you are to new experiences

People make a lot of assumptions about your personality  your selfies.

In one 2015 study, students at a Chinese university looked at selfies on a Chinese microblogging site. Most students assumed that pressed lips predicted extraversion and openness and that being alone in a photo meant the person was neurotic. But these judgments were generally wrong.

The only accurate observation students made was that positive emotion in a selfie generally predicted the person's openness to experience.

Researchers also found that friendlier people were more ly to take pictures from below; more conscientious people were less ly to reveal a private space in the background; those who were open to new experiences were more ly to display positive emotions; and neurotic people were more ly to make a duck face.

12 Small Habits That Actually Reveal a Lot About Your Personality

People show who they really are in very subtle ways—including their habits. In fact, your choices and preferences are almost as telling as your Myers-Briggs personality type. Read on to learn more about the habits that speak volumes and that reveal more about your personality than you think.


The debate about the “right way” to hang your TP has raged nearly since the roller’s invention. However, therapist Gilda Carle, PhD, claims that she can learn about your personality through your preference on this matter. She surveyed 2,000 men and women about whether they hang their toilet paper in the overhand or underhand position.

She also asked her volunteers to fill out questionnaires that would probe how assertive they were—on a scale of 1 to 10—in their relationships. Dr. Carle’s results suggest that those who prefer the overhand method are more dominant, while the underhanders tend to be more submissive.

(Some extremely dominant types even admitted to switching the paper direction in other bathrooms they visited.) “What first began as a fun exercise actually turned into an accurate assessment tool. While it adds humor to the conversation, it also provides insight on your compatibility with a prospective partner,” Carle tells the Independent.

We do know that when people invented the role this is how they want you to hang the toilet paper.


A study published in Journal of Research in Personality suggests that you can read someone’s personality through their choice in footwear. Volunteers submitted photos of their shoes and then completed a questionnaire on their personality traits.

Another group gazed upon the photos and then described the personality of the wearer—and they were remarkably accurate. They gauged the age, income, and attachment anxiety of someone based solely on the shoes.

Their results indicate that people who wear comfortable shoes tend to be relatively agreeable. Ankle boots are generally worn by those who are more aggressive.

Wearing uncomfortable shoes implies that you’re more of a calm person, while those with new and well-maintained footwear have a more anxious or clingy persona. Here are the 13 personal details your house can show people about you.

Body language expert Patti Wood tells Men’s Health that your stroll reveals your personality. If your weight is usually forward and your stride is quick, you are extremely productive and highly logical. People admire you for that, but you may come off a bit cold and competitive.

If you walk with your chest forward, shoulders back, and your head held high (common in a lot of politicians and celebrities), you are fun, charismatic, and socially adept, though you may tend to hog the spotlight. If your weight is over your legs, not forward or back, you’re more interested in people than in tasks, and more focused on your personal life than your career.

You’re great when part of a group, but tend to get distracted. Lastly, if you’re light on your toes when you walk and your eyes are glued to the floor, you’re most ly introverted and polite.

A study published in the Journal of Interpersonal Violence suggests that jail inmates with psychopathic tendencies were able to judge vulnerability and pick potential victims simply by viewing the way people walk; you might want to adopt some of those more assertive styles. And if you walk this, it says a whole lot about your personality.


A study published in the Journal of Personality and Social Psychology found your handshake can alter people’s impressions of you. In the experiment, judges were trained to assess eight characteristics of a handshake: completeness of grip, temperature, dryness, strength, duration, vigor, texture, and eye contact.

The results indicate that participants with firmer handshakes described themselves as more emotionally expressive, extroverted, and positive than others. Those with looser grips were more shy and neurotic. The judges’ first impressions correlated with this—they agreed that the participants with firmer handshakes were more confident and less socially anxious.

Here are some other observations about what your handshake says about you.


If you’re trying to pick up cues from your coworker, the answer may lie in your inbox. Psychologist Tomas Chamorro-Premuzic, PhD, writes in Fast Company that there is a strong connection between our email persona and our real-life character.

Text mining studies have found associations between certain keywords and major traits. Narcissists will generally use words such as “I,” “me,” and “mine” frequently. Extroverts tend to be more casual and talk about fun-related things, music and parties.

And it’s not only what you say—it’s how you say it. An absence of typos is a sign of someone’s conscientiousness, perfectionism, and potential obsessions, whereas poor grammar indicates lower levels of IQ and academic intelligence.

Interestingly, long emails reflect energy and thoroughness, but also some degree of neediness. Everyone should stop writing these 10 irritating phrases in emails.


Are you a nail biter or skin picker? Scientists call these “body-focused repetitive behaviors” (BFRB).

In a 2015 study published in the Journal of Behavior Therapy and Experimental Psychiatry, researchers analyzed people’s personalities and then filmed while they were in a situation that was extremely frustrating, relaxing, or boring, looking for ticks that might emerge.

People who compulsively tugged on their hair or bit their nails tended toward perfectionism, and their actions are a result of trying to soothe boredom, irritation, and dissatisfaction. Because it feels better to do something instead of nothing, repetitive behavior proves comforting. There are plenty of alternative strategies to help you shut down stress.

A study published in the Journal of Research in Personality suggests that timeliness is an accurate assessment of positive character traits. In the study, researchers asked participants to complete a personality assessment at home and come to the laboratory for a group experiment.

By analyzing the participants time of arrival, they found punctual people were more conscientious and agreeable; being early was connected to neuroticism. And those who are chronically late tended to be more laid-back.

Are you often tardy? Try some of these must-steal habits of people who are always on time.


You are what you eat—but science suggests you also are how you eat. Julia Hormes, PhD, a psychologist specializing in food behavior, and Juliet Boghossian, a Los Angeles-based behavioral food expert, told the huffingtonpost.com that food-related behaviors can tells us a lot about personality.

Slow eaters are usually people who to be in control and know how to appreciate life, but fast eaters tend to be ambitious and impatient. The adventurous eater is a thrill-seeker and risk-taker, while picky eaters are ly to exhibit anxiety and neuroticism. Lastly, if you’re someone who s to separate different foods on their plate, you’re very cautious and detail-oriented in your everyday life.

Plus, these 17 crave-worthy foods can tell you some surprisingly intimate things about yourself.


Want to get to know someone better? Take them to the mall. A series of experiments, published in the Journal of Consumer Research, found that there are two types of consumers: the explanation fiend and the explanation foe. A fiend is the type to meticulously scrutinize every single shampoo bottle in the aisle before settling for something.

On the other hand, a foe will quickly decide and be done. According to the researchers, the fiends score high on measures of cognitive reflection, meaning they analyze information to death and are detail-oriented. Explanation foes don’t do well with details and prefer more general information.

If you’re a perfectionist who loves looking at the details, you’ll love these perfectionist photos.

12 physical traits that reveal your personality (according to science)

Source: Iryna Inshyna/Shutterstock

Are we generally good at judging people's personality? Can we tell by just looking (or listening) whether a person is confident, gregarious, shy, responsible, calm, or attention-seeking?

Recent studies in psychology suggest that we can. Even when we only get a chance to look at a person for a few seconds — also known as a thin-slicing — our judgment of personality is fairly reliable.

Although we make quick judgments about personality on the basis of things  facial expression, posture, clothing, and attractiveness, we are generally reasonably accurate about initial impressions.

Naumann et al. (2009) carried out a study in which research participants were exposed to full-posture photographs in two conditions — one in which the photographed subjects had a neutral posture and facial expression (standardized condition), and another in which facial expression and posture were spontaneous (spontaneous condition).

The personalities of the people in the photographs were identified through self-reporting and reporting by acquaintances. Accuracy was determined on the basis of a comparison to self-reported personality tests, and significant accuracy was calculated on the basis of results found in other studies of accuracy in thin-slicing conditions.

The researchers found that in the standardized condition, the research participants were accurate for extraversion, emotional stability, openness, self-esteem, and religiosity. In the spontaneous condition, participants perceived nine ten traits with a significant degree of accuracy.

What is particularly impressive about this high degree of accuracy is that there was no face-to-face interaction with the people in the photographs, and hence only some degree of nonverbal cues.

One reason for the high accuracy of thin-slicing observations ly hinges on the rich information conveyed by physical appearance and the fact that this information reliably tracks people’s personality traits.

Type of clothing, hairstyle, and personal grooming all convey information about people’s conscientiousness (Albright et al.

, 1988; Borkenau & Liebler, 1992), and facial expression and posture convey information about extraversion (Kenny et al., 1992).

A lot of this information is conveyed even in still photographs, because expressive behavior often leaves marks on people’s faces, such as laugh or frown lines (Malatesta, et al., 1987). Neumann et al. (2009), for example, found that in still photographs, the most valid cues of extraversion were having an energetic stance, looking stylish and healthy, and smiling.

The accuracy of personality judgments is ly to increase in conditions that resemble real life, such as those that involve active face-to-face interaction. Still photographs provide only visual information.

Active face-to-face interaction typically provides us with auditory cues (e.g., pace of speech, conversational meaning, and discourse markers), tactile cues (e.g., the firmness of a handshake), and olfactory cues (e.g.

, a scent of perfume or a smell of unwashed hair).

An important question here, though, is why appearances of personality track reality fairly well. It is unsurprising that personality traits can leave marks on people’s faces, postures, level of grooming, and choice of hairstyle and clothing.

But many other personality markers could not plausibly be the result of personality. For example, prominent cheekbones and high eyebrows have been found to be an indicator of trustworthiness (Olivola et al. 2014).

Yet the shape of cheekbones and height of eyebrows presumably are primarily genetically determined (and hence not a mark of a certain kind of behavior).

Illustration of how we rate faces on the following four factors: (A) competence, (B) dominance, (C) extroversion, and (D) trustworthiness. The faces are presented from lowest scores on the left to highest scores on the right.

Source: Olivola, et al. 2014, used with permission.

How then do we explain the fairly high accuracy of appearances of personality?

I think the most plausible explanation is that the causal relation is reversed: Trustworthiness does not cause prominent cheekbones and high eyebrows.

Rather, features indicating trustworthiness may well be shaping people’s personality in childhood, adolescence, and young adulthood. For example, a person who is born with prominent cheekbones and high eyebrows may be signaling trustworthiness from a young age.

This, in turn, may lead us to treat the child as trustworthy. Other things being equal, this may encourage him or her to become trustworthy.

If indeed our facial and bodily features shape people's judgments of our personality, and their judgments alter our personality during childhood and adolescence, then personality is in fact much more fluent and changeable that it may at first seem, but in a rather negative way: Our biases can shape what kind of person a child grows up to be.

Scientists say you can change your personality: But it takes persistent intervention

12 physical traits that reveal your personality (according to science)

It has long been believed that people can't change their personalities, which are largely stable and inherited. But a review of recent research in personality science points to the possibility that personality traits can change through persistent intervention and major life events.

Personality traits, identified as neuroticism, extraversion, openness to experience, agreeableness and conscientiousness, can predict a wide range of important outcomes such as health, happiness and income. Because of this, these traits might represent an important target for policy interventions designed to improve human welfare.

The research, scheduled to be published in the December issue of American Psychologist, is the product of the Personality Change Consortium, an international group of researchers committed to advancing understanding of personality change.

The consortium was initiated by Wiebke Bleidorn and Christopher Hopwood, University of California, Davis, professors of psychology who are also co-authors of the latest paper, “The Policy Relevance of Personality Traits.

” The paper has 13 other co-authors.

Policy change could be more effective

“In this paper, we present the case that traits can serve both as relatively stable predictors of success and actionable targets for policy changes and interventions,” Bleidorn said.

“Parents, teachers, employers and others have been trying to change personality forever because of their implicit awareness that it is good to make people better people,” Hopwood added.

But now, he said, strong evidence suggests that personality traits are broad enough to account for a wide range of socially important behaviors at levels that surpass known predictors, and that they can change, especially if you catch people at the right age and exert sustained effort. However, these traits also remain relatively stable; thus while they can change, they are not easy to change.

Resources are often invested in costly interventions that are unly to work because they are not informed by evidence about personality traits.

“For that reason, it would be helpful for public policymakers to think more explicitly about what it takes to change personality to improve personal and public welfare, the costs and benefits of such interventions, and the resources needed to achieve the best outcomes by both being informed by evidence about personality traits and investing more sustained resources and attention toward better understanding personality change,” researchers said.

Why focus on personality traits?

Research has found that a relatively small number of personality traits can account for most of the ways in which people differ from one another. Thus, they are related to a wide range of important life outcomes.

These traits are also relatively stable, but changeable with effort and good timing. This combination — broad and enduring, yet changeable — makes them particularly promising targets for large-scale interventions.

Both neuroticism and conscientiousness, for example, may represent good intervention targets in young adulthood. And certain interventions — especially those that require persistence and long-term commitment — may be more effective among conscientious, emotionally stable people.

It is also important to consider motivational factors, as success is more ly if people are motivated and think change is feasible, researchers said.

Bleidorn and Hopwood said examples of important questions that could be more informed by personality science include: What is the long-term impact of social media and video games? How do we get children to be kinder and work harder at school? How do we help people acculturate to new environments? And, what is the best way to help people age with grace and dignity?

7 Things Your Face Says About You

12 physical traits that reveal your personality (according to science)

moriza/Flickr Newcastle, Australia “people reader” Alan Stevens is developing a system that will match career paths to a collection of personality traits that he says can be determined from jobseekers’ facial dimensions.

The 61-year-old psychologist-in-training consults with schools, recruiters and corporates on body language, facial expressions, facial features, and neurolinguistic programming.

Stevens’ methods aren’t accepted by the wider scientific community – neurolingustic programming is generally regarded as a pseudoscience and features in Neil Strauss’ controversial dating guide “The Game” – but he is in talks with Newcastle University about launching formal research on the topic.

“There is a strong statistical basis but all academics want to see further proof,” he said. “I’ve been chasing universities for some time now. What I’d to see is for this to become a course.”

Stevens’ people-reading techniques are earlier research into facial expressions by Paul Ekman, facial features by Edward Vincent Jones and Robert Whiteside, and body language by David Matsumoto.

He says facial features can reveal personality traits because they reflect both aspects that people are born with (nature), and aspects that they develop throughout their lives (nurture).

“If you look at somebody you can tell straight away if they’re fit because of muscle development,” he said. “It’s the same in the face – we have 43 muscles, and the ones you use over time will develop.”

The ratio of facial length to width is used to determine natural confidence levels. Alan Stevens Here are seven traits that Stevens says he can read from people’s faces:

1. Confidence: Indicated by the ratio of facial width to facial length.

Stevens says people whose faces are less than 60% as wide as they are long are cautious by nature, while those whose faces are at least 70% as wide as they are long are naturally confident.

2. Friendliness: Indicated by the distance between the top of the eye to the eyebrow, compared the height of the eye.

Stevens says people with higher eyebrows tend to have developed stronger muscles to do with surprised facial expressions. Those people tend to prefer more personal space.

he distance between eyes is used to determine how tolerant people are of errors. Alan Stevens 3. Tolerance: Indicated by the horizontal distance between eyes.

Stevens says people with wider-set eyes tend to be more tolerant of errors.

4. Sense of humour: Indicated by the length of the philtrum.

Stevens links a longer philtrum, which is the vertical groove between the nose and upper lip to a dry sense of humour and sarcasm, whereas people with shorter philtrums may take jokes personally.

5. Generosity: Indicated by the shape and size of lips.

Stevens says people with fuller upper lips tend to be more generous with their speech, while people with thinner lips tend to be more concise.

6. World view: Indicated by the size of the fold on a person’s eyelid.

Stevens says people with a thicker fold tend to be more analytical, whereas those with thin, or no folds, tend to be more decisive and action-driven.

7. Magnetism: Indicated by the depth of colour of eyes.

Stevens says people with deeper-coloured eyes tend to be more charismatic.

Stevens has distilled his facial profiling techniques into two mobile applications, ProfileMe and ProfileMatch, with the latter designed to recommend the best way to interact with people of various personalities.

In the coming months, he hopes to convince the Australian Department of Education to support his work into characterising the 1,800 or so jobs in its official Job Guide and linking them to personality traits that school counsellors can then determine from students’ faces.

“There are 1,800 jobs in the guide – no kid is going to sit there and go through the entire thing,” he said. “What I’d to do is come up with a list so we can say, ‘Here are some careers that may interest you’.”

9 things people can figure out about your personality just by looking at you

12 physical traits that reveal your personality (according to science)

Your looks can reveal a lot. Business Insider Looks can be deceiving.

Except sometimes, they're not.

A growing body of research suggests that people are pretty good at guessing what you're — how smart you are, your sexual orientation — just by glancing at you.

We dug up some of that disconcerting data and presented it below. Read on to find out what you're unconsciously communicating, whether you it or not.

Princeton University

Science suggests that observers can accurately judge your intelligence from a brief interaction — but only if you're actively trying to seem smarter.

In a 2007 study, 182 college students were asked to discuss an assigned topic in pairs for five minutes. Half the participants had been told privately to act intelligent and competent; others weren't given these instructions. All the interactions were filmed.

Partners then rated each other on how smart they seemed. So did 20 men and women who watched video recordings of the conversations.

As it turns out, participants generally weren't able to accurately judge their partners' intelligence. On average, the people who watched the recordings were — but only when they were evaluating participants who had been told to act intelligent.

By way of explanation, the researchers write: “[B]ehaviors that signal high or low intelligence in a social interaction may be magnified in an impression management setting. Perhaps motivation to convey a particular impression amplifies naturally occurring behavior.”

In 2010, researchers asked undergrads to review headshots of close to 100 managing partners at top law firms and rate them on different personality traits, including dominance, facial maturity, likability, and trustworthiness.

The researchers combined the partners' scores on dominance and facial maturity to create a single “power” score, and combined their scores on likability and trustworthiness to create a single “warmth” score. People who scored higher on power tended to lead firms that were more profitable.

Even weirder? The same findings held true when participants looked at college yearbook photos of 73 of the managing partners, some of which were taken half a century earlier.

People may be able to tell how religious you are simply by looking at how you hold yourself.

One 2009 study found that, on average, 123 undergrads could accurately assess 113 people's religiosity simply by looking at full-body photographs of those individuals.

In this case, religiosity was measured by asking the individuals pictured as well as three people who knew them well to complete a questionnaire.

Those who appeared to be smiling, energetic, and neat were judged to be more religious — and in fact, they usually were.

Interestingly, that study also found that participants could accurately judge how extroverted, open, likable, and self-assured the people in the photos were.


Self-obsession can be hard to hide.

In a 2009 study, researchers had 160 undergrads take a series of personality tests, including one that measured narcissism. Researchers also asked participants to have three people close to them fill out questionnaires about their personalities.

Then, seven other undergrads looked at full-body photos of all the participants and try to rate them on different personality traits.

Results showed that, on average, the observers were relatively skilled at predicting narcissism based solely on the participants' physical appearance. Specific cues that the observers relied on included a neat, organized appearance; flashy, revealing clothing, makeup, and expensive, stylish clothes.

The researchers write: “These results suggest that narcissists do seem to alter their appearance (consciously or unconsciously) in a way that reflects their appearance-oriented motives.”

9 surprising things your physical appearance says about you

12 physical traits that reveal your personality (according to science)

You're not supposed to judge a book by its cover, but that doesn't stop us from judging one another by our looks.

There's a lot a person will assume about you your physical appearance — from how trustworthy you are to whether you're an extrovert. Your appearance can also reveal things about your health, such as your lihood of developing certain diseases. 

Here are just a few of the things your body can reveal about you.

Sharing the full story, not just the headlines

People can (accurately) judge your personality from a photo.

They say first appearances can be deceptive. But people can tell a surprising amount about your personality from a photograph, one study found.

The study involved showing people photos of 123 undergrads at the University of Texas at Austin in two poses: One where they were told to face the camera with a neutral expression, and one in which they could pose however they wanted.

Then, strangers were asked to judge them on certain aspects of their personality. No matter what position they took, viewers were surprisingly accurate: While people were better at judging someone's extroversion, self-esteem, religiosity, agreeableness, and conscientiousness when they were spontaneous, they could also judge the first three traits when they were posed.

​Shallow Tinder: 'You're the prettiest girl but I get turned on by someone slimmer'

People judge your physical strength your facial bone structure.

Scientists recently did a study where they showed people photos of 10 different people with five different facial expressions, and asked them to rate how friendly, trustworthy, or strong the person in the photo appeared.

Not surprisingly, viewers tended to rank people with a happy expression as more friendly and trustworthy than those with angry expressions. But when it came to traits physical strength, broad faces were seen as stronger.

Women are attracted to “manly” men during certain times of their cycle.

A woman's romantic preferences can vary over the course of her menstrual cycle, some research suggests. A 2010 study of 66 heterosexual couples found that women whose partners had less masculine faces said they were more attracted to other men when they were ovulating. By contrast, women with masculine-faced partners felt less ly to stray.

But that's not the whole story, though: Other studies suggest that women who are on the pill prefer men with less manly faces.

People on death row may be more ly to get the death sentence if they have an “untrustworthy” face — but we're really bad judges of criminality.

Ted Kaczynski in his booking mug shot from April 1996

How people perceive our faces could be a life-and-death matter. In July, researchers published a study in which they showed around 200 people photographs of men on death row in Florida and asked them to rate their trustworthiness.

Created with Sketch. Created with Sketch.

Those who were rated as having untrustworthy-looking faces were more ly to be sentenced to death, the researchers found.

More concerning about the research, however, was this fact: The study participants also tended to rate death-row convicts who were later exonerated as less trustworthy-looking than those who were eventually convicted.

Although we can't say having an untrustworthy face caused all these men to get the death sentence, the finding is still disturbing.

Your appearance also speaks volumes about your health. Wrinkles, for example, can be a sign of poor heart health.

Pruney skin can reveal more than just age — it may also tell us something about how our hearts are doing.

A 2012 study compared the amount of wrinkles on the faces and upper inner arms of a group of 261 people with long-lived parents to a random group of 253 people the same age.

Women with the lowest risk of heart disease were described as looking more than two years younger for their age than those with the highest risk.

Doctors can tell if you're sick by looking at your eyes.

Doctors can diagnose a number of conditions just from looking into your eyes.

Red spots of blood in the retina (the light-sensitive layer at the back of the eye) can be a sign of diabetes known as diabetic retinopathy.

If your blood sugar levels get too high, it can block the blood vessels in the retina, which can then swell and burst. If left untreated, this can impair vision or even cause blindness.

Of course, a number of other things can cause red eyes as well, including pink eye, an infection of the tissue on the inside of the eyelid and white of the eye, or a fungal infection.

For men, finger length may be linked with penis size …

In one study, scientists measured the length of the fingers and penises (both flaccid and stretched) of 144 Korean men age 20 and older who were anesthetized for urological surgery. They found that a shorter index-finger-to-ring-finger ratio was correlated with a longer stretched penis length.

Both finger length and penis length are influenced by testosterone exposure in the womb. This finger ratio has also been linked to a host of other things.

… and cancer risk.

Gentlemen: While your finger length may suggest you're well endowed, it may come at a cost. Scientists studied the finger lengths of 1,500 prostate cancer patients and 3,000 healthy men over a period of 15 years by asking them to look at pictures of hands and choose one that resembled their own.

Men who said their index fingers were the same length or longer than their ring fingers were one-third less ly to be diagnosed with prostate cancer over the course of the study than men whose index fingers were relatively shorter, and the effect was even larger for men under age 60. Of course, the study was the men's reported finger length, not actual measurements, so further studies are needed.

Your height could reveal your risk of certain diseases.

Being tall or short could be more than a matter of attractiveness. Some studies suggest that taller people have a lower risk of cardiovascular diseases, while shorter people may have lower rates of cancer.

The effects are believed to do with the amount of growth hormone produced, which can protect against some diseases but increase the risk of others.

The findings do not necessarily mean that being tall or short will prevent you from getting either disease, however.
