Positive and negative personality traits: every trait has two sides

What do people mean by positive and negative personality traits?

They usually mean traits that are pleasant to be near and traits that are not. The positive lists run to kind, honest, reliable, calm, curious and confident. The negative lists run to moody, lazy, rude, arrogant, closed-minded and anxious. They are stable across websites because they draw on the same thing: ordinary social approval, not measurement.

That is a reasonable way to talk and a poor way to think about yourself. Social approval is local, and a room that rewards agreeableness one week rewards toughness the next. The words also mix categories. Some name a tendency, some name a behaviour, and some name a verdict on a person who inconvenienced the writer.

Personality research does not work this way. It describes broad dimensions that people are spread along, arrived at by seeing which trait words move together in large samples rather than by deciding which ones are admirable (Goldberg, 1993). Once you measure a dimension instead of praising one end of it, both ends turn out to carry consequences.

Why does the evidence describe every trait as two-sided?

Because when researchers follow a trait out into real outcomes, the findings land on both sides. Conscientiousness is the clearest case for the positive list: it was the one Big Five trait that predicted job performance across every occupational group in a classic meta-analysis (Barrick & Mount, 1991), and a meta-analysis of the behaviours contributing most to mortality found it related to more of the protective ones and fewer of the risky ones (Bogg & Roberts, 2004). Those are real advantages. The same high end is where inflexibility and difficulty stopping live, and people who work with a very high scorer feel the standard as well as the benefit.

Agreeableness is similar. A meta-analysis of 19 samples found that a person's Agreeableness related to greater relationship satisfaction in their partner (r = .15), with the partner's low neuroticism the strongest correlate of all (r = -.22) (Malouff et al., 2010). It is also what makes it hardest to hold a line in a negotiation or stay in a conflict that needs finishing. Extraversion is the most consistent personality correlate of leadership emergence and effectiveness (Judge et al., 2002), and it is also what fills a room with the loudest view rather than the best one.

Emotional Stability carries the plainest cost at its low end. Extraversion tracks positive feeling and Neuroticism tracks negative feeling, as separate systems rather than as two ends of one scale, and personality measured earlier predicted happiness 10 years later (Costa & McCrae, 1980). That is not a small thing to carry. What the low end also brings is vigilance: trouble noticed early, preparation before it is needed, other people's discomfort registering sooner.

Openness trades the same way. It has the loosest links to job performance of the five, with one exception: it predicted how well people did in training, which fits a trait defined by appetite for the unfamiliar (Barrick & Mount, 1991). Its low end buys focus and practicality. Honesty-Humility is a factor in its own right rather than a restatement of Agreeableness, and five-factor instruments capture only part of its variance (Ashton et al., 2014); its high end is also where people undersell themselves and get passed over.

Which traits do people most often call positive?

Six words carry most of the positive lists. Each is a position on a dimension, usually on a particular facet inside it, which is more useful than the compliment.

• Kind: high Agreeableness, mostly its Altruism and Sympathy facets. The cost is that helping is not free, and high scorers are the last to say so.
• Honest: high Honesty-Humility, its Sincerity and Fairness facets. The cost is that candour is expensive in rooms that do not want it.
• Reliable: high Conscientiousness, its Dutifulness and Self-Discipline facets. The cost is that obligations accumulate toward whoever keeps them.
• Calm: high Emotional Stability, its Calmness facet. The cost is a slower alarm, in yourself and in reading other people.
• Curious: high Openness, its Inquisitiveness facet. The cost is attention that follows the interesting rather than the important.
• Confident: two dimensions at once, Social Boldness and Assertiveness under Extraversion, Self-Confidence under Emotional Stability. The cost is a gap between certainty and accuracy.

Naming the facet rather than the compliment is what makes a word usable. "Be kinder" is not a plan. "Say yes to one fewer thing this week" is a change at the size of a facet.

Which traits do people most often call negative, and how else can they be read?

The same six dimensions, read from the other end by someone who was inconvenienced. Each has a plain, non-judgemental reading that describes the same person.

• Moody: lower Emotional Stability, near its Equanimity and Calmness facets. The reading: feeling arrives fast and strongly, which also makes a mood in a room hard to hide from them.
• Lazy: lower Conscientiousness, near Industriousness and Self-Discipline. The reading: effort is not automatic and needs a reason. The same position is where spontaneity lives.
• Rude: lower Agreeableness, near Politeness and Tender-Mindedness. The reading: the unwelcome thing gets said. Teams that never hear it pay elsewhere.
• Arrogant: lower Honesty-Humility, near Modesty. The reading: high self-regard, which supports risk-taking and negotiation and erodes trust once it is tested.
• Closed-minded: lower Openness, near Open-Mindedness. The reading: loyalty to what has been shown to work, and resistance to a method that is merely fashionable.
• Anxious: lower Emotional Stability. The reading: threat detected early and prepared for. The cost is genuine, and falls on well-being rather than on competence (Costa & McCrae, 1980).

None of that makes the cost imaginary. Someone whose lateness keeps landing on other people has a real problem to solve. The point is that the problem is a behaviour in a situation, and the trait word is a summary that has quietly added a verdict to a description.

Why is fixing a bad trait the wrong frame?

Partly because trait words are too big to act on, and partly because the target is usually wrong. If both ends of a dimension carry costs, moving toward one end does not remove the costs. It trades them. Someone who raises their Conscientiousness to stop missing deadlines can arrive at a different complaint from the same colleagues six months later.

Traits do move, less than the self-improvement shelf claims and more than the fatalists do. A systematic review of 207 intervention studies found trait change of about a third of a standard deviation over roughly six months, largest for Emotional Stability, and drawn mostly from therapy and counselling trials, with the change still present at follow-up (Roberts et al., 2017). People who named the trait they wanted to change and then set specific behavioural goals shifted further than people who only held the intention (Hudson & Fraley, 2015).

So: pick the situation, not the adjective. Write down the behaviour you want there, at the size of a single repeatable act, and expect modest change over weeks. Check first whether the trait is the problem at all, because much of what gets blamed on a trait is a mismatch between a person and a job, a household or a week. The longer treatment is at can personality change.

How does Wellington report traits without calling them good or bad?

Wellington is a science-based personality assessment from Therabot Labs LLC. It measures personality as continuous traits, built on the Big Five and HEXACO models, and writes the results back as a personal report rather than a type.

Scores come back in three bands, named Quiet, Balanced and High rather than low, average and good. Each statement is rated on a five-point accuracy scale, each trait is the average of its statements, and that average is placed against a reference sample as a percentile: Quiet below the 30th, Balanced to the 70th, High above. Those norms are provisional until the norming sample is complete. The bands and the Portrait names exist to make the result easier to talk about; the percentile is the measurement, and it is always shown alongside. The free Snapshot asks 60 questions, takes about 7 minutes and covers Extraversion, Agreeableness, Conscientiousness, Emotional Stability, Openness to Experience, Honesty-Humility. The first ten are answered before anything is asked of you; after question ten you sign in with an email so answers are saved and results can be shown. No card is needed.

In the written report, every trait has three pages, one per band, written in advance by the writing and psychology team, and your answers choose which one you read. None of the three has a villain in it: the Quiet page for Conscientiousness says what flexibility buys as well as what it costs, and the High page names rigidity alongside follow-through. The Wellington Membership, $4.99 a month, adds 336 questions and reaches 90 traits, including the facets named above and all 24 VIA character strengths (Peterson & Seligman, 2004), then continues toward all 255 traits. The methodology shows how a band reads.

A band is a position, not a grade, and not a prediction about any single day. Wellington is a wellness tool for reflection, not a medical or psychological diagnosis, and it does not replace care from a qualified professional. It is not designed for hiring, and you can export or delete your data at any time. How to read personality test scores explains what a percentile does and does not mean.

Questions people ask

What are the most common positive personality traits?

Kind, honest, reliable, calm, curious and confident appear on almost every list. Each is the high end of one of the six dimensions. The evidence supports the advantages, particularly for Conscientiousness at work and in health (Barrick & Mount, 1991; Bogg & Roberts, 2004), and it shows a cost at each of those high ends as well.

What are the most common negative personality traits?

Moody, lazy, rude, arrogant, closed-minded and anxious. All six are low ends of the same dimensions the positive list draws on, described by someone who was inconvenienced. Each has a plain reading: early emotional signal, effort that needs a reason, candour, self-regard, loyalty to what works, and vigilance. The costs are real, but they sit alongside something.

Can a negative personality trait be changed?

Somewhat, and more reliably than people expect. A review of 207 intervention studies found trait change of about a third of a standard deviation over roughly six months, largest for Emotional Stability, and drawn mostly from therapy and counselling trials (Roberts et al., 2017). Wanting it is not enough: people who set specific behavioural goals moved further than people who only held the intention (Hudson & Fraley, 2015).

Is there a best personality profile?

No, and a test that implies one is selling a value judgement. Every position on every dimension has advantages and costs that depend on the work, the household and the decade you are in. Higher Conscientiousness helps with long projects and can shade into rigidity. Lower Extraversion suits deep work and can leave a good idea unheard.
