Exploring the secrets of the curse of knowledge - how
understanding this cognitive bias can improve our communication, teaching, and
decision-making skills.
The term the “curse of
knowledge” was coined in a 1989 paper by researchers Colin Camerer,
George Loewenstein, and Martin Weber. This phenomenon is sometimes also
conceptualized as epistemic egocentrism,
though some theoretical distinctions may be drawn between these concepts.
Because the curse of knowledge can cause issues in various areas of life, such as when it comes to communicating with others, it’s important to understand it.
The Curse Of Knowledge: Common Occurrences & Influences
Teaching Beginners: The Curse of Expertise --> This can make it harder for experts to teach beginners (also known as the curse of expertise). For example, a math professor might find it difficult to teach first-year math students, because it’s hard for the professor to account for the fact that they know much more about the topic than the students.
Communication Breakdown: Knowledge Gap --> This can make it harder for people to communicate. For example, it can be difficult for a scientist to discuss their work with laypeople, because the scientist might struggle to remember that those people aren’t familiar with the terminology in the scientist’s field.
Predicting Behavior: Expectations vs. Reality --> This can make it harder for people to predict the behavior of others. For example, an experienced driver may be surprised by something dangerous that a new driver does, because the experienced driver struggles to understand that the new driver doesn’t understand the danger of what they’re doing. This aspect of the curse of knowledge is associated with people’s expectation that those who are less-informed than them will use information that the less-informed individuals don’t actually have.
Understanding Past Decisions: Clarity vs. Hindsight --> This can make it harder for people to understand their own past behavior. For example, it can cause someone to think that they were foolish for making a certain decision in the past, even though the information that they had at the time actually strongly supported that decision. This aspect of the curse of knowledge can manifest in various ways and be referred to using various terms, such as the hindsight bias, knew-it-all along effect, and creeping determinism.
When it comes to the curse of knowledge, the perspective of the less-informed individual, whether it’s a different person or one’s past self, is often referred to as a naive perspective.
The Tapping Study
One well-known example of
the curse of knowledge is the tapping study. In
this study, participants were randomly assigned to be either
a tapper or a listener.
However, in reality, listeners were able to successfully identify the tune based on the finger tapping in only 2.5% of cases, which is far below even the most pessimistic estimate provided by a tapper, and which therefore represents evidence of the curse of knowledge.
Overall, the tapping study demonstrates how the curse of knowledge can affect people’s judgment. Specifically, it shows that people who know which tune is being tapped have an easy time identifying it, and therefore struggle to accurately predict the perspective of others, who don’t have the same knowledge that they do.
The Psychology & Causes Of The Curse Of Knowledge
The curse of knowledge
is attributed to two main cognitive mechanisms:
People’s curse of
knowledge can be caused by either of these mechanisms, and both mechanisms
may play a role at the same time. Other cognitive mechanisms may
also lead to the curse of knowledge. For example, one such
mechanism is anchoring and adjustment, which in this
case means that when people try to reason about a less-informed
perspective, their starting point is often their own perspective, which
they struggle to adjust from properly.
In addition, various factors, such as age and cultural background, can influence people’s tendency to display the curse of knowledge, as well as the way and degree to which they display it.
Finally, other
psychological concepts are associated with the curse of knowledge. The most
notable of these is theory of mind,
which is the ability to understand that other people have
perceptions, thoughts, emotions, beliefs, desires, and intentions that are
different from our own, and that these things can influence people’s
behavior. Insufficient theory of mind can therefore lead to an increase in the
curse of knowledge, and conversely, proper theory of mind
can reduce the curse of knowledge.
Dealing with The Curse Of Knowledge
There are several things
that you can do to reduce the curse of knowledge:
Other Debiasing Techniques
We can use various general debiasing techniques, such as slowing down our reasoning process and improving our decision-making environment. In addition, we can use debiasing techniques that are meant to reduce egocentric biases, such as visualizing the perspective of others and then adjusting our judgment based on this, or using self-distancing language (e.g., by asking “are you teaching in a way that the students can understand?” instead of “am I teaching in a way that the students can understand?”).
It is important to keep in mind that none of these techniques may work perfectly in every situation. This means, for example, that some techniques might not work for some individuals in some circumstances, or that even if a certain technique does work, it will only reduce someone’s curse of knowledge to some degree, but won’t eliminate it entirely.
Related Biases
The curse of knowledge
is considered to be a type of egocentric
bias, since it causes people to rely too heavily on their own point
of view when they try to see things from other people’s perspective.
However, an important feature of the curse of knowledge, which differentiates
it from some other egocentric biases, is that it is asymmetric, in the sense that
it influences those who attempt to understand a less-informed
perspective, but not those who attempt to understand a more-informed
perspective. The curse of knowledge is also associated with various
other cognitive biases, such as:
