The power of our mind comes not from its ability to observe, but its ability to apply these observations to create assumptions about the world around us. In doing so our mind goes beyond the information given, our sensory information, and uses these assumptions to respond in an appropriate manner. For our purposes an assumption is any belief or prediction we have about an object or situation that could not be ascertained solely from the information given to us by our senses and is based on prior experiences with the purpose of giving us reliable information to use. Our mind makes assumptions because without doing so it would need to treat every event as a new problem to be solved, when one’s mind finally did come to the solution, it would likely be one it had come to innumerable times before. As such, assumptions tend to be helpful shortcuts that allow us to use less processing power.
No matter what someone is doing they are relying on assumptions, allowing them to react faster and more consistently. All of the assumptions our mind makes stem from the overarching assumption that the world around us is fairly predictable and reactions to similar situations will elicit similar results. There are basic assumptions such as, objects have consistent mass, small objects have less mass than large ones, and objects fall down, which allow us to move around and manipulate objects in a predictable manner. An example of an automatic assumption that our brain makes is location tagging where we bind features based on their physical location, meaning if the features orange and round are in the same location, then then they are assumed to be on the same object which is both orange and round. An example of how this assumption can be incorrect can ...
