If you haven't mastered the fundamentals, you haven't made yourself an analytical thinker. Nobody can engage in analytical reasoning if they are unsure of what it entails or where to begin. Strong critical thinking abilities are typically associated with success in one's field. For instance, clinicians may encounter difficulties when identifying and treating a patient with an undiagnosed disease. If you lack both skill and sound judgement when your patient doesn't actually exhibit enough symptoms to support the diagnosis of his illness, the doctor runs the risk of losing him as a patient.
