Philosophical razors are principles or rules of thumb used in philosophy and decision-making to eliminate unlikely explanations for a phenomenon or avoid unnecessary actions. They help in theorizing about why and how things happen when there is limited information. Some well-known philosophical razors include Occam's razor, Hanlon's razor, and Einstein's razor. Occam's razor states that the simplest explanation should be preferred over a complex one, while Hanlon's razor advises not to attribute to malice that which can be adequately explained by stupidity. These razors serve as critical thinking tools to eliminate noise, strip away unnecessary parts, and better understand problems, enabling better decision-making
