If one accepts the basic notion that reasoning is often in the context of problem situations and can be represented in the form of an argument, then there are a number of places where critical reasoning can focus. First, let’s focus on the problem situation itself. One might focus on the so-called problematic situation and question the facts pertaining to the situation. Suppose the problematic situation is that a significant number of persons are not performing as expected in a particular course. One might ask how many or what percentage are performing poorly, or how poor performance is being defined, or whether this situation has persisted for a period of time. Other questions are also possible that address the facts of the situation or that ask for clarification of key aspects of the situation (e.g., performance criteria). One might also ask questions about the desired state of affairs that reflect a level of critical thinking. For example, one might ask how the desired situation was determined or whether and to what extent achieving the desired situation is realistically attainable.
Additionally, one can inquire what kinds of transformations are required to resolve the problematic situation and why they might be expected to result in the non-problematic situation. Such questions go well beyond simply accepting the claim that doing X, Y and Z will lead to the desired outcome. This can be called questioning the underlying theory of change involved in the argument.
One can also frame critical reasoning skills in terms of the underlying argumentation. First and foremost, one can ask the fundamental question of whether or not adequate evidence has been provided in support of the conclusion – do the premises provide strong support for the conclusion? This is different from asking whether or not one agrees with the premises, as one might agree with all the premises of an argument that still fails to provide adequate support for the conclusion. This question about the adequacy of the evidence addresses the form of the argument rather than the content. First focus on the form of the argumentation.
Once the form of the argument is deemed acceptable (a step that is often overlooked), one can then focus on the various pieces of evidence and ask whether or not they should be believed or accepted as convincing. This often leads one to ask about what assumptions have been made. Because assumptions are often not stated, an important critical reasoning skill is making the assumptions explicit and then asking whether or not there is sufficient reason to accept those assumptions.
One can perform a similar kind of provisional or hypothetical reasoning with regard to the conclusion of the argument. One can ask what else must be accepted if one accepts the conclusion. It can happen that a conclusion that might first appear to be reasonable will lead one to other statements or situations that are clearly unacceptable but left unstated or not addressed in the argument. Thinking ahead to the implications of accepting the conclusion is one form of critical reasoning. In summary, one can think of critical reasoning skills in terms of those skills required to assess arguments and to determine if what is alleged to resolve a problematic situation is likely to do so. These skills are not trivial yet they are important in nearly every discipline and in many everyday problem solving situations. It is a wonder that so little emphasis is placed on developing these skills, especially at an early age.
