Do You Suffer From the Dunning-Kruger Effect?

Do You Suffer From the Dunning-Kruger Effect?

Charles Darwin once noted, “Ignorance more frequently begets confidence than does knowledge.” We all know the modern man to whom Darwin refers: the unemployed “musician” who must inform all new acquaintences that he is, in fact, a musician (multiple times). The XHTML and jQuery “expert,” who uses XHTML as a selling point.

And if you don’t know this guy, maybe you are him!


Dunning-Kruger

It’s referred to as the Dunning-Kruger effect.

The Dunning–Kruger effect is a cognitive bias in which unskilled people make poor decisions and reach erroneous conclusions, but their incompetence denies them the metacognitive ability to recognize their mistakes. The unskilled therefore suffer from illusory superiority, rating their ability as above average, much higher than it actually is, while the highly skilled underrate their own abilities, suffering from illusory inferiority.

You don’t even know enough to realize just how little you know.

I recently mentioned on Twitter that, from my experiences, those who label themselves as experts, more often than not… aren’t. This isn’t surprising; it stands to reason – to phrase it casually – that those who have the goods…don’t flaunt the goods! Alternatively, if one’s expertise is persistently revealed to you, by said expert, perhaps something is a few clicks off!

A guitar teacher of mine in college, once – rightly so – informed me: “You don’t even know enough to realize just how little you know.”

Little did my teacher know that this comment would stick with me for a long time. The irony, of course, is, despite the fact that years and years have passed since my conversation with him, his note still applies.

Whether the craft be music or web development, I’m not even close to an expert. Or, as Willy Brown might say, I’m not even the beginnings of a pimple on the late great Robert Johnson’s ass.

“Actual competence may weaken self-confidence, as competent individuals may falsely assume that others have an equivalent understanding. As Kruger and Dunning conclude, “the miscalibration of the incompetent stems from an error about the self, whereas the miscalibration of the highly competent stems from an error about others.”


How to Detect a Self-Proclaimed Expert

According to Wikipedia, for a given skill, self-proclaimed experts will:

  • tend to overestimate their own level of skill
  • fail to recognize genuine skill in others
  • fail to recognize the extremity of their inadequacy
  • recognize and acknowledge their own previous lack of skill, if they can be trained to substantially improve.

Those who genuinely know their stuff are considerably modest, when compared to those who have a fraction of their experience and knowledge.

Maybe the easiest way to detect a real expert is via that very word: “expert.” Is it inaccurate for me to argue that true experts rarely refer to themselves as such, if ever? There’s that idea again: “the more you know; the more you realize how little you know.”

Everything’s relative, of course, but I’ve found that those who genuinely know their stuff are considerably modest, when compared to those who have a fraction of their experience and knowledge. Perhaps this is simple human nature. Blissful ignorance and dreams are many times preferable to actual work. It’s easier to brag about your next million dollar web application, than to actually create it. It’s more impressive to use the terms “gig” and “contract,” when you really mean, “freebie website for my sister.”

So the question remains: why do some represent expertise, while others seemingly avoid the term? I suppose I can’t speak to the former, though I can provide some personal notes on the latter.

  • First and foremost, I know in my heart that I have a long way to go before I can even fathom embracing that label – if ever.
  • The term, “expert” is a vague one, and is entirely relative. Sure, to a high school student, maybe we are experts. To my personal web development heroes, I feel like a hack. I’m sure the chain continues indefinitely. This is precisely why it’s important to refrain from using these sorts of labels in most cases.
  • Particularly in our field, no one is an expert. The industry is too young, and advances at an alarming rate. There’s always new skills to acquire. I’d argue that those who understand this truth also understand that terms like “expert” are inappropriate.
  • On a more casual and social level, you come across as a jerk when you self-diagnose yourself this way. This is similar to continuously retweeting compliments. Let your work/code do the talking, and, if you genuinely deserve the label, others will be more than happy to assign it to you. This is the correct way to achieve “expert” status. It is given…not proclaimed.

Is It Ever Okay to Call Yourself an Expert?

Is it in poor taste to designate yourself as an expert? Ultimately, it’s just a word; do what you wish. I’m admittedly being a bit pedantic here.

Christian Heilmann argues:

“Sometimes, you need to call yourself an expert to reach people who are badly in need of information.”

That’s certainly a valid case, and is particularly applicable when considering events like conferences and workshops. When you host a workshop, regardless of whether you label yourself as an expert, you assume that role. When it comes to spreading education, Christian is right: sometimes you must use these terms to attract those in need. And in these teacher-student relationships, you are the expert. No harm done.

We also must consider simple marketing or SEO. To John Doe, who needs a website for his new business, it’s important to remind him that we are the “experts.” As more and more tools, which allow regular folks to create websites, are released, they should be made aware that others have dedicated their lives to learning this craft. Don’t risk the livelihood of your business, all for the sake of saving X dollars on the website. You are the expert. John Doe must know this. To the Layman, sure, abuse the term!

However, among your peers, you might think twice before labeling yourself in this way.

Arrogance is not inspiring.

This is not to say that you shouldn’t be confident in your worth and abilities. Never devalue your worth to an employer or client. That said, though, unless you are one of the few truly exceptional veterans in our industry, stop patting yourself on the head, and get back to doing what we all must do in our free-time: learning. Whether you’re an industry veteran or a college student, we all share one commonality: we spend as much free time as possible desperately trying to remain relevant in this ever-expanding industry.


Conclusion

As a reader of Nettuts+, I think it’s safe to assume that, like me, you’re considerably aware of the skills you don’t yet have. Hopefully, Nettuts+ can help with that! Until next time, I’ll leave you with this quote:

“One of the painful things about our time is that those who feel certainty are stupid, and those with any imagination and understanding are filled with doubt and indecision.” – Bertrand Russell

    Great article, Jeffrey! Very interesting to learn there’s a term for this effect. I think a lot of marketplace authors have observed (or participated in) both sides of the Dunning-Kruger effect as they handle support requests :)

  • bitster

    You should have read the whole paper, or at least the whole article on wikipedia. It has a key phrase that makes this study pretty much useless in finding the ‘village idiot’.

    “the competent group accurately estimated their rank”

    This means that a self-proclaimed ‘expert’ is not in fact an ignorant, based solo on his ratings. Yes, expert is a vague term, but also it doesn’t mean a person who knows everything. Or that he’s the best in his field.

    I don’t see advertising like “Mediocre PHP developer here. You can find literally thousands of better developers in my area, but please pick me! I have like 10 goats I have to provide organic food to.”

    • http://www.jeffrey-way.com Jeffrey Way
      Author

      I did read it all.

      Of course these are generalizations. The article is meant mostly for discussion.

      And I never said anything about the “village idiot.” It’s just interesting to notice those who seem surprisingly confident (about everything), despite the fact that their skills don’t compliment this arrogance. Where does it come from? That’s what I’m curious about.

      If a reader doesn’t relate to this article (one side or the other) in any way, then they don’t suffer from the effect. :)

        Just wanted to say that I completely agree with your article Jeff. As I surf the internet I often see many people bragging to the masses how smart they are, how many books they’ve read, or how good they are in a certain field and consider the rest inferior(mostly gamers that is).

        I think it’s arrogant and ignorant to brag yourself on a forum or web site about anything, and I think it has to do with an inferiority complex. You know people that need to show to others they are better, superior, but in fact they feel inferior, just to boost their self esteem.Else I can’t explain myself why would they react in this way. I mean I don’t know the ones to whom I’m talking to on a forum, why should I suddenly want to brag ?

        It’s easier to brag about something online, and call the others stupid, then to show them that you actually know those things.

        I respect and appreciate your work and your tutorials, I’ve learned many things from you and from the other web developers that write tutorials on nettuts. And you all seem modest people, I haven’t seen any of you brag about “how good you are”, I wonder why that is ? :)

        P.S: I also don’t brag about the stuff that I know or I’ve learned, I know my limits, and I’m relying myself on what socrates said that “I know that I know nothing”, because there is so much knowledge in this world, that it’s ignorant to say that you know it all.

    I totally agree and appreciate that you moderated your commentary to include the legitimate needs and situations that call for people labelling themselves or being labelled as experts but what I take away from it from personal experience is as you expressed that there is always room to grow and learn. I definitely feel like a hack when I read some of the cool tutorials on this site but at the same time it makes me excited about learning more and becoming better, to the point of offering my own tutorial one day.

    I blogged about your article here, with your permission of course:

  • http://www.webmentor.cr/ Marco Berrocal

    Saw your Tweet yesterday. I wonder wtf happened that got you in this mode to write this eh? :)

    About the article, I tend to agree. I do think that true experts know to some degree that they are but keep it to them themselves. And that is, as it should be. One should be humble about it. I didn’t know that people suffering from this effect failed to recognize the talent in other.

    Another thing I have also noticed about “experts” is that they lack passion about their work. No pride. No love for it. Just the word to carry them around.

  • Michael A. Hess

    It’s funny. I both look forward to Net tuts every day and also dread Net tuts every day. Why? Because no matter how competent I feel I am in my knowledge and skills that I possess to do my job, it always seems that Jeff writes another article that makes me feel like the development/programming universe has left me standing along the side of the road some place.

    Just when I feel I am up to speed on the industry and building stuff in the main stream manner along comes another article showing me that yet again some where along the line I missed the boat. I am exceedingly grateful for the articles that Jeff ( and the others ) do because it is keeps me abreast of techniques that I would most likely miss and not be able to take advantage.

    My constant ignorance bows before you Jeff.

  • http://joshriser.com Josh Riser

    I think this article is great. I can’t say, however that I suffer from this effect. I have never (and probably never will) refer to myself as an “expert”. I’ve been at web design/development for nearly 5 years and even over the past 2-3 I have always just said “Just above average”, never “expert”, because I know there can’t be an “expert” per-se, just someone who is significantly better or more knowledgeable than you are.

    Thanks for the procrastination article, though :)

    F*ck… I need to rethink my entire image of myself. I constantly look at other websites, and in my mind say “well I can do better than that” but this sentiment is not backed up by my past work at all.

    Thanks for the enlightening read, I’m going to make a conscious effort to reevaluate what my skill level really is and be completely honest with myself and others, however harsh the truth might be. I hope other readers actually take a shocking realization away from this.

  • http://www.wdonline.com Jeremy McPeak

    In my younger years, I certainly suffered from Dunning-Kruger. Dig deep enough on the web, and you can find some pretty stupid stuff coming from my brain through my fingers–all came from the skewed perception that I knew what I was talking about when I really didn’t. Thankfully, some of the most stupid comments/statements coming from my fingers were under a variety of handles.

    Today, I guess I can say that I don’t. I don’t consider myself an expert in anything. Knowledgeable? Sure, but not to the extent as the real experts. But… that won’t stop me from putting expert on a resume or when talking with clients.

  • http://www.nilsgroot.nl Nils

    Interesting read, never really gave much thought to experts since I always thought of myself as a student. When I am not learning or writing HTML, CSS, Javascript, PHP, CodeIgniter, Zend or Smarty.net, I try to learn something new (currently, that’s Java) or read interesting articles like this one, or funny articles like 14 Ways you can be Sure you’ve Married a Geek.

    I feel like the pressures of society can cause the Dunning Kruger effect. The less skilled don’t want to feel left behind, so some try to fake it, others don’t however.

    As for the opposite end of the spectrum, I feel like the modest people with skills are likely younger and haven’t fully experienced their potential. As they age and grow wiser, they are more aware of their limitations and what they are and are not experts on. Thus the bias is gone. Again this doesn’t apply to everyone.

    Good post.

    It’s the infinite recursive loop one enters when appreciating yet another thing you can’t understand and explain to three levels of why that is so difficult. BUT! The solution is to observe the moon without saying anything… great for fostering humility and perspective. And for the love of all wild things: lose the notion that you have to know every framework that every college kid across the world develops. These things are supposed to make your life easier!

  • http://www.catgirlalexandra.wordpress.com Laura Garcia

    The universe is infinite, and so is knowledge. We are only an “expert” when there is no one on the planet who knows anything about the “whatever” it is that no one knows about but you. I been doing PHP for years now, more a back-end person by nature and people have called me an expert. In my free time I try to absorb whatever interests me, and I am overwhelmed by the talent of others such as Jerry Way and many others in web development community. I am no expert but I strive to be, maybe someday to be one of the experts if there is truly such a thing…

    I have come across many so called experts and they usually turn out to be lacking in whatever they say they are experts in. Those who are out there refrain from using the term expert there is only one expert in all things God!

    Great read Jeffrey, I always look forward to reading and learning from you. Keep up the good work!

    I most certainly suffer from the Dunning-Kruger effect.
    I’d like to think that it’s all in my past, and that I don’t suffer from it anymore – but I know for a fact this is actually a symptom of the effect (and I’ve looked back and said I don’t suffer before, and then looked back on that saying I do)!

    Hopefully it’s something I’ll grow out of, because it annoys the hell out of me – but I guess I’ll just have to live with it for the time being.

  • Charlotte Enns

    On the other side of the coin (just playing devil’s advocate here)…

    While it’s true that many people overestimate their own sense of self-worth and self-importance, why is self-confidence something to be ashamed of? Why do people feel the need to fake modesty? Why is it that we only like people who aren’t threatening to us (read: to our egos) or who don’t make us feel inferior in some way, even when they are, in fact, more literate (or well-read), articulate, successful, better educated, better qualified, etc. than we are?

    • Cosmin

      No one likes false modesty, but I don’t think that the ones who brag on the internet about something they are in fact good or literate, on the contrary. An educated literate person doesn’t brag about the books he’s read or how intelligent he is. A self proclaimed literate, expert person isn’t credible.

      If you really are aware of your education and knowledge you don’t have to brag, but to show through facts that you in fact are smart and educated.

      • Cosmin

        Why the most literate persons, the most educated and the wisest, the best in their field are always modest ? Look at Steve Jobs, or at the guys and gals here on nettuts, they don’t have to brag, because they are showing us they know their stuff through their books and tutorials. ;)

    I think it is interesting that on this forum, nothing has been stated that the Dunning-Kruger effect is cultural specific. Please do not extend the effect to other cultures around the world.

    For those of you who may have not read even the basic information on wikipedia:

    Dunning-Kruger effect is basically:
    The more ignorant a person is about the standards of performance, the louder they toot their own horn of competence.

    Ever run into one of those people who act like they know everything? The type of people that think only their opinion is worth gold when it’s a steaming pile of monkey flung feces? Those people are actually exhibiting the signs of the Dunning-Kruger effect. An effect that almost literally means that the person (or persons) affected are too stupid to realize that what they are saying is extremely dumb. Not to mention this lack of understanding makes them in a somewhat deluded state where there confidence in their crap idea is extremely out-of-proportion and they seem to think the concept is an astounding revelation that must be an offer strait from the ethereal stream of ultimate knowledge.

    I find that this effect is most pronounced in the first few years of acquiring a skill – I suffered the same myself.

    Year one: learning and obviously learning.
    Year two (and sometimes year three too): thinks he or she is bulletproof and knows it ALL.
    Year three+: realises that it’s all about continually learning.

    Some stay in “year two” mode – I am sure we all know these people!
