If you play a game of football, you make sure you know the rules of the game. In this way, you can design winning strategies, you can work out what is acceptable play and what you can get away with. The rules contained within football ensures all participants are on the same wavelength. Our goal is clear: to win the game as the rules allow. This is true no matter what country you are in. England has soccer, New Zealand rugby, Australia has AFL. Each game of football has different rules, but the goal is the same: to win. In the same way, it is important that if you are a citizen of a country you must know the rules of the game (constitution). You must know the strategies to win (election process). You must know what you can get away with (acceptable and agreed upon methods of changing laws), and whether you can rely on your “captain” (representative) to do his or her best for your constituency (your team).
This is a simple analogy but true. Most people will play a sport and be aware of many of the “ins and outs” of the game, but feel some form of frustration, boredom or even derision when confronted with political science classes.
The study of politics is both humanistic and scientific. In this way it is one of the more difficult sciences as it attempts some measurement and study of human behavior, which is the most unpredictable subject matter. What makes it even more difficult is that political scientists have to use their skills in not only a domestic setting, but also in how this domestic setting influences and is influenced by the rest of the world. This is particularly true of the USA, who are viewed as one of the world's leaders.
For these reasons, it is important that we learn about political science. This should commence at an early age so people can become active citizens and in control of "the game."
