I’m fascinated by the various ways that we incorrectly perceive the world around us. For instance, I recently read about a cognitive fallacy that I like because I have experienced it’s truth: People who are beginners in a field tend to overestimate their ability in that field because they don’t have enough knowledge to know just how little they actually know.
Personally, I would love to be able to create better illustrations using a vector art tool. Seems simple enough, until you realize that seeing computer art is way easier than constructing computer art. Ignorance is bliss, but in the case of this fallacy it can quickly cause people to get in over their heads. When I saw this chart, I thought it was a wonderful and hilarious illustration of this exact concept (from the DataViz blog):
It’s important to remember that as we assess our abilities or our knowledge that we don’t know how much we don’t know. Especially at the beginning, we are not the best judges of how good we are. Experience makes a huge difference.
