Humans have limited time and brainpower. As a result, they use simple rules of thumb—heuristics—to help them make judgments. An example would be “availability.” Suppose I ask you if Dhruv is a common name. If you are from most countries in the world you would likely say no, but it happens to be a very common name in India, a country with a lot of people, so on a global scale it is in fact a rather common name.
