Skepticism is a universal skill that can be applied to any domain that requires reasoning, such as science, philosophy, history, politics, economics, education, and more. Regardless of the domain, the basic principles of skepticism remain the same. To illustrate how skepticism can be applied in different domains, let's take a closer look at science, philosophy, and history. In science, skepticism helps you test hypotheses, design experiments, analyze data, and draw conclusions based on empirical evidence and logical reasoning. When it comes to philosophy, skepticism allows you to examine the nature, meaning, and validity of concepts, arguments, and beliefs. As for history, skepticism helps you evaluate sources, evidence, and interpretations of historical events. In each domain you should ask questions such as: What is the hypothesis or concept? What is the structure of the argument? What is the source and evidence? What is the interpretation? How reliable are they? How relevant are they? How plausible are they? By asking these questions you can gain valuable insights into the domain and improve your understanding of it.
