Known by many as the fastest game on two feet, lacrosse requires intelligent thinking and players to always be aware of their surroundings. Numerous unusual situations can arise during a match, making it essential that players can react quickly and make decisions on the fly. Our success in these situations can largely be attributed to the thought system, System One or System Two, that we use to make that choice. In his book Thinking, Fast and Slow, Daniel Kahneman explains the two critical ways of thinking and how each works. System One, an automatic and simple way of thinking, handles about 98% of all our mental processing. This system responds quickly to situations, often leading to errors. System two, a slow, coherent thought process, uses much more energy and accounts for only 2% of our thinking. Through extensive practice, lacrosse players can train themselves to program System One responses while using System Two thinking in practice. Say no to plagiarism.

Simple and complex tasks are completed using System One as it requires much less effort than System Two. In most cases, System One runs automatically while System Two remains in the background. When both systems agree, impressions are transformed into beliefs. System One turns to System Two only when it encounters a problem and an event violates the "model world" created by System One. System One supports and updates the model of the world around it, made up of what we consider normal. An example of a System One characteristic is association. The brain is constantly making connections between multiple words and ideas. When we hear an unpleasant word our immediate reaction will most likely be negative. System One often attempts even complex problems. As automatic and simple as it is, System One doesn't deal with complex situations in the best way; makes decisions quickly and without controlling his thoughts. Because of this laziness, most people tend to place too much trust in their basic intuitions and not exert the effort needed to think more intuitively. This makes system 1 very susceptible to easy errors. It relies on heuristics to avoid asking for help from System Two, which applies the ideas of System 1 instead of monitoring its work. Heuristics are methods and shortcuts used by S1. These are useful when solving a problem with System 1. This method of thinking is not guaranteed to be optimal or rational, but is useful for solving problems that require quick thinking. S1 links words, places and people together to help associate memories and emotions with certain experiences. System two, on the other hand, is our conscious mind. This system thinks logically and deliberately. An example of System Two thinking is parking in a tight space. This cannot be done effortlessly and requires System One to ask System Two for support. Our methodical System Two rarely takes over, making conscious decisions only in puzzling and unfamiliar situations. System Two doesn't like to make great efforts. It has a controlled thought process that burns more energy than System One. Thoughts and actions that require a lot of attention and concentration are used through System Two. Despite its accuracy, System Two has its flaws. It has a very small capacity to contain.
