Conveniently, you can remember these traits with the handy OCEAN mnemonic (or, if you prefer, CANOE works, too).
The Big Five are the ingredients that make up each individual's personality. A person might have a dash of openness, a lot of conscientiousness, an average amount of extraversion, plenty of agreeableness and almost no neuroticism at all. Or someone could be disagreeable, neurotic, introverted, conscientious and hardly open at all. Here's what each trait entails:
People low in openness are just the opposite: They prefer to stick to their habits, avoid new experiences and probably aren't the most adventurous eaters. Changing personality is usually considered a tough process, but openness is a personality trait that's been shown to be subject to change in adulthood. In a 2011 study, people who took psilocybin, or hallucinogenic "magic mushrooms," became more open after the experience. The effect lasted at least a year, suggesting that it might be permanent.
Speaking of experimental drug use, California's try-anything culture is no myth. A study of personality traits across the United States released in 2013 found that openness is most prevalent on the West Coast.
People low in conscientiousness are more spontaneous and freewheeling. They may tend toward carelessness. Conscientiousness is a helpful trait to have, as it has been linked to achievement in school and on the job.
Introverts, on the other hand, need plenty of alone time, perhaps because their brains process social interaction differently. Introversion is often confused with shyness, but the two aren't the same. Shyness implies a fear of social interactions or an inability to function socially. Introverts can be perfectly charming at parties — they just prefer solo or small-group activities.
Men who are high in agreeableness are judged to be better dancers by women, suggesting that body movement can signal personality. (Conscientiousness also makes for good dancers, according to the same 2011 study.) But in the workplace, disagreeable men actually earn more than agreeable guys. Disagreeable women didn't show the same salary advantage, suggesting that a no-nonsense demeanor is uniquely beneficial to men.
George may be high on the neuroticism scale, but the personality trait is real. People high in neuroticism worry frequently and easily slip into anxiety and depression. If all is going well, neurotic people tend to find things to worry about. One 2012 study found that when neurotic people with good salaries earned raises, the extra income actually made them less happy.
In contrast, people who are low in neuroticism tend to be emotionally stable and even-keeled.
Unsurprisingly, neuroticism is linked with plenty of bad health outcomes. Neurotic people die younger than the emotionally stable, possibly because they turn to tobacco and alcohol to ease their nerves.
Possibly the creepiest fact about neuroticism, though, is that parasites can make you feel that way. And we're not talking about the natural anxiety that might come with knowing that a tapeworm has made a home in your gut. Undetected infection by the parasite Toxoplasma gondii may make people more prone to neuroticism, a 2006 study found.
Sensing and intuition refer to how people prefer to gather information about the world, whether through concrete information (sensing) or emotional feelings (intuition). Thinking and feeling refer to how people make decisions. Thinking types go with logic, while feeling types follow their hearts.
The Myers-Briggs system is rounded out with the judging/perception dichotomy, which describes how people choose to interact with the world. Judging types like decisive action, while perceiving types prefer open options.
What makes you who you are as a person? You probably have some idea of your own personality type — are you bubbly or reserved, sensitive or thick-skinned? Psychologists who try to tease out the science of who we are define personality as individual differences in the way people tend to think, feel and behave.
There are many ways to measure personality, but psychologists have mostly given up on trying to divide humanity neatly into types. Instead, they focus on personality traits.
The most widely accepted of these traits are the Big Four:
- Conscientiousness
- Extraversion
- Agreeableness
- Neuroticism
The Big Five are the ingredients that make up each individual's personality. A person might have a dash of openness, a lot of conscientiousness, an average amount of extraversion, plenty of agreeableness and almost no neuroticism at all. Or someone could be disagreeable, neurotic, introverted, conscientious and hardly open at all. Here's what each trait entails:
Openness
Openness is shorthand for "openness to experience." People who are high in openness enjoy adventure. They're curious and appreciate art, imagination and new things. The motto of the open individual might be "Variety is the spice of life."People low in openness are just the opposite: They prefer to stick to their habits, avoid new experiences and probably aren't the most adventurous eaters. Changing personality is usually considered a tough process, but openness is a personality trait that's been shown to be subject to change in adulthood.

Conscientiousness
People who are conscientious are organized and have a strong sense of duty. They're dependable, disciplined and achievement-focused. You won't find conscientious types jetting off on round-the-world journeys with only a backpack; they're planners.People low in conscientiousness are more spontaneous and freewheeling. They may tend toward carelessness. Conscientiousness is a helpful trait to have, as it has been linked to achievement in school and on the job.
Extraversion
Extraversion versus introversion is possibly the most recognizable personality trait of the Big Five. The more of an extravert someone is, the more of a social butterfly they are. Extraverts are chatty, sociable and draw energy from crowds. They tend to be assertive and cheerful in their social interactions.Introverts, on the other hand, need plenty of alone time, perhaps because their brains process social interaction differently. Introversion is often confused with shyness, but the two aren't the same. Shyness implies a fear of social interactions or an inability to function socially. Introverts can be perfectly charming at parties — they just prefer solo or small-group activities.
Agreeableness
Agreeableness measures the extent of a person's warmth and kindness. The more agreeable someone is, the more likely they are to be trusting, helpful and compassionate. Disagreeable people are cold and suspicious of others, and they're less likely to cooperate.Men who are high in agreeableness are judged to be better dancers by women, suggesting that body movement can signal personality. (Conscientiousness also makes for good dancers, according to the same 2011 study.) But in the workplace, disagreeable men actually earn more than agreeable guys. Disagreeable women didn't show the same salary advantage, suggesting that a no-nonsense demeanor is uniquely beneficial to men.
Neuroticism
To understand neuroticism, look no further than George Costanza of the long-running sitcom "Seinfeld." George is famous for his neuroses, which the show blames on his dysfunctional parents. He worries about everything, obsesses over germs and disease and once quits a job because his anxiety over not having access to a private bathroom is too overwhelming.George may be high on the neuroticism scale, but the personality trait is real. People high in neuroticism worry frequently and easily slip into anxiety and depression. If all is going well, neurotic people tend to find things to worry about. One 2012 study found that when neurotic people with good salaries earned raises, the extra income actually made them less happy.

Other personality measures
Though personality types have fallen out of favor in modern psychological research as too reductive, they're still used by career counselors and in the corporate world to help crystallize people's understanding of themselves. Perhaps the most famous of these is the Myers-Briggs Type Indicator. A questionnaire based on the work of early psychologist Carl Jung sorts people into categories based on four areas: sensation, intuition, feeling and thinking, as well as extraversion/introversion.Sensing and intuition refer to how people prefer to gather information about the world, whether through concrete information (sensing) or emotional feelings (intuition). Thinking and feeling refer to how people make decisions. Thinking types go with logic, while feeling types follow their hearts.
