Probably many of us have heard the saying that “knowledge is power” at least once in our lifetime. This phrase comes from the Latin aphorism "scientia potentia est" (the words can be placed slightly differently, but it doesn’t change the meaning). Commonly, it’s attributed to Sir Francis Bacon, former Lord High Chancellor of Great Britain, as the expression "ipsa scientia potestas est" ('knowledge itself is power') occurred in his book “Meditationes Sacrae” (1597).
As you can see, Francis Bacon didn’t use the exact aphorism that’s assigned to the “knowledge is power” saying. The first time this exact Latin phrase was written was in the 1668 version of “Leviathan” by Thomas Hobbes, an ex-secretary to F. Bacon.

Yet, even though knowledge is power, everyone carries different levels of it. And this leads to the phenomenon of the “curse of knowledge” or “the curse of expertise.” It’s a cognitive bias where people incorrectly assume that everyone knows as much as they do on a certain topic. This makes it hard for them to imagine what it’s like to not have that knowledge.
One of the most interesting experiments done about this curse, which also quite easily explains the phenomenon, was conducted in 1990 by a Stanford University psychology graduate student Elizabeth Newton. She created a game, where people were assigned roles of “tapper” and “listener.” Tappers had to tap out the rhythm of a well-known song on a table, while the listeners had to guess the song.
Out of 120 songs tapped out during the experiment, only 3 were guessed correctly. Yes, only 3! Apparently, when a tapper taps, they hear the tune in their mind along with the taps, while the listener only hears the uncoordinated tapping sounds. And due to the curse, the tappers couldn’t see why it was so hard for listeners to understand the tune.

This works with any other type of knowledge. Knowing some piece of information makes it hard to understand how others don’t know it, hence the curse in the phenomenon’s name.
And it’s not the only thing that's so cursed about it. In fact, this phenomenon creates quite a few problems between people:
- Makes some teachers have difficulty understanding how their students can’t comprehend a topic;
- Makes it difficult to communicate;
- Makes it hard to understand or justify your own past behavior;
- Makes it hard to predict or understand the behavior of others.
So, be aware that as you learn new things from this list, you might fall for the curse of knowledge. After all, as the question that prompted this thread suggests, the majority of people don’t know these facts, so don’t forget that!

And to do the math, the surface area of a circle is pi x r squared.
Pi is the constant. 18 in pizza has a 9 in radius, or r. 12 inch has
6. 9 squared is 81, 6 squared is 36. 36 x 2 is 72. 81 is greater than 72.
