We make sense of the world around us primarily through our experience - what we've been exposed to, our interactions, our perceptions and the stories we hear. In other words, we are biased by what's available to us - what Daniel Kahneman and Amos Tversky call the availability heuristic. This bias creates a mental shortcut that makes it possible for us to solve problems quickly and simply. These shortcuts are everywhere in our thinking and even in our perceptions. And most of the time, they work just fine. They save time and energy, which is a tremendous advantage. But when dealing with things that are more complex or abstract or that involve large numbers of people or large amounts of information, this general sense is not enough. That means decisions on your money and investments, for instance, are going to require you to think a little differently... |
