We tend to assume we know more than we actually do from "summary" of The Knowledge Illusion by Steven Sloman,Philip Fernbach
The idea that we tend to overestimate our own knowledge may seem counterintuitive at first. After all, we live in an age where information is readily available at our fingertips. With a few taps on a keyboard or a swipe on a screen, we can access a wealth of knowledge on virtually any topic. This easy access to information can create a false sense of expertise. We mistake familiarity with a subject for true understanding, leading us to believe that we know more than we actually do. This illusion of knowledge is not just a personal delusion; it is a fundamental aspect of human cognition. We are social creatures, and our knowledge is often distributed among our social group. When we encounter a gap in our understanding, we rely on others to fill in the blanks. This collective knowledge allows us to function in a complex world, but it also blurs the line between what we know individually and what we know as a group. Our tendency to overestimate our knowledge is exacerbated by the way our minds work. We are wired to seek out information that confirms our existing beliefs and ignore evidence that contradicts them. This confirmation bias can create a distorted view of our own expertise, as we selectively focus on information that supports our preconceived notions. The illusion of knowledge has far-reaching implications, affecting everything from personal decision-making to public policy. When we overestimate our understanding of a topic, we are less likely to seek out new information or consider alternative viewpoints. This can lead to poor decision-making and a failure to address complex issues effectively. Recognizing the limits of our own knowledge is the first step towards combating this illusion. By acknowledging that there are gaps in our understanding and seeking out diverse perspectives, we can overcome the tendency to assume we know more than we actually do. This humility is essential for fostering true intellectual growth and promoting a more informed society.
