Every day, a sea of decisions  stretches before us. Some are small and unimportant, but others have a larger impact  on our lives. For example, which politician should I vote for? Should I try the latest diet craze? Or will email make me a millionaire? We're bombarded with so many decisions that it's impossible to make  a perfect choice every time. But there are many ways  to improve our chances, and one particularly effective technique is critical thinking. This is a way of approaching a question that allows us to carefully  deconstruct a situation, reveal its hidden issues, such as bias and manipulation, and make the best decision. If the critical part sounds negative that's because in a way it is. Rather than choosing an answer  because it feels right, a person who uses critical thinking subjects all available options to scrutiny and skepticism. Using the tools at their disposal, they'll eliminate everything but the most useful and reliable information. There are many different ways of approaching critical thinking, but here's one five-step process that may help you solve  any number of problems. One: formulate your question. In other words,  know what you're looking for. This isn't always as straightforward  as it sounds. For example, if you're deciding whether to try out the newest diet craze, your reasons for doing so may be obscured by other factors, like claims that you'll see results in just two weeks. But if you approach the situation with a clear view of what you're  actually trying to accomplish by dieting, whether that's weight loss, better nutrition, or having more energy, that'll equip you to sift through  this information critically, find what you're looking for, and decide whether the new fad really suits your needs. Two: gather your information. There's lots of it out there, so having a clear idea of your question will help you determine what's relevant. If you're trying to decide on a diet to improve your nutrition, you may ask an expert for their advice, or seek other people's testimonies. Information gathering helps you weigh different options, moving you closer to a decision that meets your goal. Three: apply the information, something you do  by asking critical questions. Facing a decision, ask yourself, "What concepts are at work?" "What assumptions exist?" "Is my interpretation of the information logically sound?" For example, in an email that promises you millions, you should consider, "What is shaping my approach to this situation?" "Do I assume the sender  is telling the truth?" "Based on the evidence, is it logical  to assume I'll win any money?" Four: consider the implications. Imagine it's election time, and you've selected a political candidate based on their promise to make it cheaper for drivers to fill up on gas. At first glance, that seems great. But what about the long-term  environmental effects? If gasoline use is less  restricted by cost, this could also cause a huge surge in air pollution, an unintended consequence  that's important to think about. Five: explore other points of view. Ask yourself why so many people are drawn to the policies of  the opposing political candidate. Even if you disagree with  everything that candidate says, exploring the full spectrum of viewpoints might explain why some policies that don't seem valid to you appeal to others. This will allow you  to explore alternatives, evaluate your own choices, and ultimately help you make more informed decisions. This five-step process is just one tool, and it certainly won't eradicate difficult decisions from our lives. But it can help us increase  the number of positive choices we make. Critical thinking can give us the tools to sift through a sea of information and find what we're looking for. And if enough of us use it, it has the power to make the world a more reasonable place.
