Critical thinking is a form of higher level thinking, sometimes called the scientific way of thinking. Critical thinking helps you make decisions by analyzing and evaluating your facts. Work on improving your critical thinking skills, so you can make more intelligent decisions.
Determine the problem that you are trying to solve. Make sure you remain open-minded and objective when looking at the problem. Be aware of your own biases and set them aside.
Develop a hypothesis and outline a possible solution. Brainstorm other possible solutions. Thinking critically involves being open to new ideas. Outline the pros and cons of each solution.
Gather information regarding the problem including information that supports and contradicts your position. Gather information supporting and refuting all possible solutions. You need all the facts to make an intelligent unbiased decision. Find your information in more than one place so that you know you have a full perspective on the problem.
Analyze all the gathered facts and analyze each part of the problem. Don't assume anything. Look at the facts objectively taking into consideration where the information came from and how current it is.
Evaluate your information and how it backs up or refutes your hypothesis. Question every answer you find. Make sure the information came from reliable sources and look at the biases of people providing the information.
Determine a reasonable conclusion based on all the facts. Question your conclusion analytically and decide whether it is a reasonable conclusion.
Make sure your facts are accurate and don't assume anything is true without proof. You may assume that A causes B but there might be a third fact, C , that causes both. Use statistics as evidence.
