Five elements of critical thinking are identifying the problem, research, identifying biases, inferences, and determining relevance (Erstad, 2018). During critical thinking, whenever a topic is chosen, the identification of the issue is crucial (Erstad, 2018). One needs to decide the problem that one wants to deal with. Credible sources of research help to think critically. Bias can ruin research, so identifying bias and eliminating it is crucial to the critical thinking process (Erstad, 2018). The ability to infer and draw conclusions helps in the necessary thinking process. Finally, one should determine the relevance of the information.
