Personality and Character: Is There a Difference?

I once conducted a job interview with someone I found to be passionate, energetic, intelligent, engaging, and prepared. As I asked her questions designed to produce an accurate picture of her potential future performance, I remained attuned to my emotional reactions to her demeanor, trying to hear what my inner voice was telling me about her. At the end of the interview, I found myself excited about the prospect of her coming to work for me. I had to remind myself to remain cautious, however, as I reflected on just how easy it is to confuse personality with character and how critical it is to separate them.

What's the difference?

Personality is easy to read, and we're all experts at it. We judge people funny, extroverted, energetic, optimistic, confident—as well as overly serious, lazy, negative, and shy—if not upon first meeting them, then shortly thereafter. And though we may need more than one interaction to confirm the presence of these sorts of traits, by the time we decide they are, in fact, present we've usually amassed enough data to justify our conclusions.

Character, on the other hand, takes far longer to puzzle out. It includes traits that reveal themselves only in specific—and often uncommon—circumstances, traits like honesty, virtue, and kindliness. Ironically, research has shown that personality traits are determined largely by heredity and are mostly immutable. The arguably more important traits of character, on the other hand, are more malleable—though, we should note, not without great effort. Character traits, as opposed to personality traits, are based on beliefs (e.g., that honesty and treating others well is important—or not), and though beliefs can be changed, it's far harder than most realize.

Why does it matter?

The problem in forming judgments about a person's suitability for important roles in our lives (employee, friend, lover, spouse) is that we all have an uncanny predilection for observing attractive personality traits and manufacturing out of them the presence of positive character traits (that is, if someone is outgoing, confident, and fun we're more likely to think they're honest, moral, and kind). But it's far from clear that the one kind tracks with the other. In fact, as I recounted in Listening To Your Inner Voice, that assumption often gets us into trouble.

We unconsciously tend to connect personality to character for two main reasons: we want to like people we already like, and the most reliable way to assess a person's character is laborious and time-consuming. (We actually need to observe people in character-challenging situations in order to make reliable deductions about their character. For example, if we observe someone lie easily, we can be reasonably certain from even just one instance that they've done so in the past and will do so again in the future, as the best predictor of future behavior is past behavior.)

This is because the beliefs that drive us to do things like lie easily, or tell the truth, are present in us at all times. They may remain "dormant" until circumstances stir them up in such a way that they motivate observable action, but they're rarely hidden away deliberately. Which begs the question: might there be a way to glimpse such beliefs without waiting for circumstances to put them on full display?

In a word—yes. Not so much by speaking directly with people whose character you're trying to uncover, but by speaking with people who know the people whose character you're trying to uncover. This is why, for example, wise prospective employers always call references.

The challenge, though, once we do is that prospective employees provide references they expect will speak well of them. The trick, then, is to ask questions of a person's references designed to get them to reveal their most accurate judgments honestly.

Questions like "Have you ever known X to lie?" aren't useful because the answer you get will depend on the character of the person you're asking. You won't know if a reference is comfortable lying themselves, so the veracity of any answer you get will remain questionable at best. For this reason, it's better to ask questions that push people to apply their own judgment. These kind of questions are more likely (though certainly not in all circumstances) to return honest answers. Therefore, instead ask things like, "What in your judgment is X's greatest weakness?" The implication here is that everyone has weaknesses, so it's unreasonable to expect the answer to be "none." It's harder to make up a weakness on the spot than to tell the truth about a weakness that a reference actually perceives, so you're more likely to get an honest assessment. Your reference may try to play down the weakness they reveal, but you can read between the lines.

The drawback to this technique is that it relies on the judgment of individuals, which we know is biased and often flawed. This drawback can be overcome, however, by asking the same questions of many people who know the person in whose character you're interested. As I wrote in a previous post, The Wisdom Of Crowds, if multiple people independently return similar answers, the likelihood that their collective judgment will be accurate is high.

Though it may seem Machiavellian, you can apply this process to friends and potential mates as well. The average length of time, for instance, people date before deciding to marry is approximately three years in the United Kingdom (a figure, I should note, that varies widely by culture). The challenge with deciding to marry someone after knowing them only three years, for example, is that some important character traits, good and bad, may not have revealed themselves by then. Of course, it's socially awkward bordering on inappropriate to interrogate a potential mate's friends and family about them directly. And though I'm not suggesting anyone do this, I am suggesting we can and should pay attention to data as it's presented to us by others as they may be in possession of better data than we are. People generally have a hard time hiding their true feelings about others over time, so if you hear common themes from people close to the person in whose character you're interested, pay attention. You're almost certainly hearing the truth.

I don't mean by any of the above to imply that personality isn't important. But when we're making decisions about who to let into our lives in critical roles, character must be considered equally important, if not more so, but is often readily overlooked. Luckily for me, the references of the person I interviewed all that time ago not only provided strong endorsements but endorsements whose content was consistent. I hired her and over time I found her to be as outstanding as her references predicted she would be.
