Cognition: the act or process of knowing; perception, process of thinking, knowledge. Elements of thought: points of view, purpose, assumptions, concepts, question at issue. Do something about pollution and its negative consequences. Benefits of less pollution but also cost. Host of technical ecological and ethical concepts required to understand multidimensional problem. Interpret and infer from all of this the best solution (conclusion) Two reasons to study analytic thinking: being able to understand and reason from facts and data is critical skill in many domains, the rise of (cid:498)big data(cid:499) and analytics, even highly educated people suffer from (cid:498)illusions of thought(cid:499) Illusions give us insight to how processes work: there are (cid:498)cognitive illusions(cid:499) and (cid:498)perceptual illusions(cid:499) Error doesn"t mean we"re stupid (cid:498)work the numbers. No matter what common sense may tell you, work the numbers(cid:499) (cid:523)money ball(cid:524: proper understanding of data can help avoid errors.
