Like everyone, you have skills that you are good at and other skills that you are not so good at. It is important to be correctly aware about how good or bad you are at something. If you overestimate how good you are at something, it can lead to embarrassment when people discover that you are not as good as you claimed to be. If the activity that you thought you were good at concerned something that affected people’s lives (e.g. you are a surgeon who incorrectly thinks that you can do a certain surgery well) then this kind of thinking may even cause real harm.
Unfortunately, your brain may sometimes falsely make you feel that you are good at doing a certain activity, when in reality, you are not that good at doing that activity. Psychologists have named this kind of stupid thinking, where your brain overestimates your capabilites, as the “Dunning – Kruger effect”. The name is based on the names of the two psychologists who first described it: David Dunning and Justin Kruger.
Here is a short example of Dunning-Kruger effect thinking:
Alice used to sing in her local school. All her classmates praised her singing ability and this made Alice feel that she was an excellent singer. She even felt confident that she would someday become rich and famous because of her singing. To focus on her music, Alice even ignored her other school subjects.
After some months, Alice contacted a professional music company and told them about her ability to sing well. The company was planning a musical show and invited Alice to join one of their rehearsals so that they could hear her sing.
When Alice went for the rehearsal, she had to sing along with other singers. As she sang with the other singers, she (and everyone else !) quickly realised that her singing was hopeless. Alice was nowhere as good as she thought she was, and she realised that it was futile to continue trying to be a professional singer.
Once Alice realised that a professional music career was not for her, she returned back to her school. Luckily with hard work, she managed to catch up with all the school subjects that she had ignored when trying to be a professional music singer.
As the above example shows, Dunning – Kruger effect thinking can lead you to disappointment and wasted time. However, I am not saying that you should consider yourself useless at everything and not take up challenges. There are many activities where you need to try that activity first before you can make any judgement about how good or bad you will be at it.
To prevent Dunning – Kruger effect thinking, it is important to get honest feedback from those around you about your abilities. You will get honest feedback only if you are truly open to receiving criticism. Make it clear to those giving you feedback that you would genuinely appreciate their honesty. When asking for feedback, it could be useful to use sentences like, “I would be grateful if you will give me feedback as to how good or bad my singing is, as I need to know if I should spend money on professional singing lessons or should spend it on something else instead.” In this way, you are telling people that you have thought of other options, and this should make it easier for them to give you negative criticism if necessary. Also, when looking for feedback, it is important to include people who are knowledgeable in the subject you are getting feedback on. Your friends may be great, but are they really the best qualified to say if you have a future as a top singer?
So beware of Dunning-Kruger effect type of stupid thinking, as it may take you up to imaginary heights and then suddenly let you fall down to reality!
