Named as the seventh most influential economist in the world, (by The Economist, 2002) Daniel Kahneman has been revolutionary to the field of psychology. Kahneman’ Nobel prize acceptance lecture “ Maps of Bounded Rationality” touches upon a variety of subjects in psychology and discusses his own landmark discoveries. In this paper I will analyze the collaborative work of Kahneman and Amos Tversky and its contributions to the general public’s psychology knowledge. I will also highlight the parallels found in this lecture with themes, theories, and information we have been recently studied in class.

Heuristics are the rules that people use to make decisions and judgments. They are responsible for eliminating unnecessary clutter and having one come to a decision quickly. An offshoot of hutertics are the system deviations such as logic, rational choice theory, and probability. When heuristics do not work properly, people develop cognitive biases which skew perception from reality. Kahneman and Tversky found three heuristics that account for a wide rage of intuitive judgments. This study investigated how human beings make real-world judgments and how/why certain conditions make those judgments unreliable. This research was groundbreaking because it challenged the age-old belief that all humans are rational beings. Kahneman himself explains this saying “Social scientists in the 1970s broadly accepted two ideas about human nature. First, people are generally rational, and their thinking is normally sound. Second, emotions such as fear, affection, and hatred explain most of the occasions on which people depart from rationality. Our article [Science 1974] challenged both assumptions” ( Kahneman in Quotes and Questions, J. Krueger Ph.D., 2012). This brave leap into the world of heuristics established most of the knowledge of the subject we have today. Since its detection in the 1970s,there is still a debate whether heuristics are actually rational by nature. Fellow psychologists and social scientists argue that heuristics’ purpose, to quickly process decisions with minimal demand of the brain's resources is rational because they are made hastily, without full information. Although they are possibly as accurate as long drawn out decision making
In his book, Everything is Obvious, Duncan Watt starts off reasonably well in explaining how certain beliefs or perceptions influence our way of thinking and decision making. These sets of beliefs are accumulated through past experiences, surrounding environments and cultures in which collectively form the philosophy of common sense. Though common sense is powerful tool that helps us navigate through our life smoothly without encumbering our brains into reflecting on every single detail. The author considers it as a set of fallible mental patterns that are invisible to us, yet have a powerful affect that extends to our way of thinking as well predicting the future of certain things in our life. In the book, Watt exposes the reality of common sense which convinces us that we know more than what we really do. Consequently, we keep making same mistakes and learning less from the past. "Bad things happen not because we forget to use our common sense, but rather because the incredible effectiveness of common sense in solving the problems of everyday life causes us to put more faith in it than it can bear."(Watt 23).
ABSTRACT: In light of interpreting a paradox of irrationality, vaguely expressed by Donald Davidson in the context of explaining weakness of will, I attempt to show that it contains a significant thesis regarding the cognitive as well as motivational basis of our normative practice. First, an irrational act must involve both a rational element and a non-rational element at its core. Second, irrationality entails free and intentional violation of fundamental norms which the agent deems right or necessary. Third, "normative interpretation" is only possible for objects that are both natural events and capable of mental operations which presuppose some freedom of will as well as constructive representation of the surrounding reality. Fourth, there is always a question of whether we strike the best balance between fitting individual mental items consistently with the overall behavior pattern and keeping our critical ability in following certain normative principles which constitute our rational background. Fifth, the paradox of irrationality reflects and polarizes a deep-seated tension in the normative human practice under the ultimate constraints of nature. Finally, the ultimate issue is how we can find the best lines on which our normative rational standards are based-"best" in the sense that they are close enough to limits of human practical potentialities and are not too high as to render our normative standards idle or even disastrous.
The process of making a decision previously held two paths, rational and irrational, with rational having the mind at work to think about what were the choices and irrational with no really engagement. Anything beyond that process of thought was not taken until the topic of System 1 and System 2 along with effects of “Relativity” were expressed in Thinking Fast and Slow, by Kahnemna and Predictably Irrational by Ariely, respectfully. Along with the other readings, the process of our decision making were no longer solely based on two very simplified and underdeveloped ideas, but as series of network and systems of decisions the minds functions through.
Rational choice theory, developed by Ronald Clarke and Derek Cornish in 1985, is a revival of Cesare Becca...
His first book Attention and Effort was published in 1973, in which he focused his study on attention, which was seen as an irrelevant topic of choice to work on during Titchener’s time (Kahneman, 1973). However, Dr. Daniel Kahneman concerned himself with the concept of attention since it may be or is one of the foundations that take part in hesitation within decision making, including the different subsets attention has when it comes to our mental processes. In Judgment Under Uncertainty: Heuristics and Biases (1982), the book looks at judgment and the attributions of behavior through predicting the possibilitie(s) of choices. Well-Being: The Foundations of Hedonic Psychology was published in 1999, which mainly concentrates on the scientific effort to comprehend the concept of human pain and pleasure; one of Kahneman’s most well known works in social psychology. Then in 2000, he and along with colleagues published Choices, Values, and Frames, as they discussed their alternative of prospect theory and elaborates on the approaches towards the efficacy of choices people make. The fifth book, Heuristics and Biases: The Psychology of Intuitive Judgment, was released in 2002 to try and help answer subjective questions of complex situation of the world/life through an objective perspective. Lastly, Kahneman’s most recent work was issued in 2011, Thinking, Fast and

“Humans are not a rational animal, but a rationalizing one” (“Class 20”). This was asserted by the much acclaimed, significant, and influential social psychologist Leon Festinger as referencing to his theory of Cognitive Dissonance. Social psychology is “a branch of psychology particularly concerned with understanding social behaviors such as” incentive and compliance (Sheehy). Festinger’s contributions to the social and cognitive branches of psychology as well psychology overall prove themselves worthy to today. This theory specifically challenged many common notions that were seemingly already accepted by behaviorists everywhere during his time (Tavris and Aronson). Its reality awakens its verifications. Consecutively, its “enormous motivational power” affects many on a daily basis (Tavris and Aronson). In the final analysis, the theory of Cognitive Dissonance by Leon Festinger is fundamental to behaviorism while directly changing the way human beings across the planet think and do.
Rationality and good judgement are typically affected by certain ways of thinking which are often studied within the psychological community. Within the community, these different ways of effected thinking are called cognitive biases. Breaking down the overall umbrella of the term cognitive bias yields subcategories of decision-making, social and memory biases, among others. Biases such as these affect all humans in one way or another. My personal experience with cognitive biases include confirmation bias, authority bias and egocentric bias. This list is definitely not complete, as I am sure there are many more biases I experience without even realizing what is happening. That being said, the first experience I would like to present is

Professor Ariely enlightens the subject so as to how the human mind tends to lapse from the rational behavior, which in turn, reinforce each other and turn out to be totally predictable and systematic manners in which our minds are expected to act. Thus, a depiction of how behavioral economics differs from traditional economics. There is a focus on how the human mind is instigated so as to judge the relativity of value and prices that are unrelated to supply and demand, the relationship between economic norms of behavior and social ones, under the influence of strong emotions. The approach used is simple as well as straightforward, with is a light-hearted, jargon-free prose comprising of bold claims, thus is persuasive. Ariely makes use of
Tversky and Kahneman, major investigators of irrationality in human judgments, asserted that “logic of choice does not provide adequate foundation for decision making.” People tend to believe that their judgments are logical selections based upon their knowledge and experiences. But in reality, the judgments are not completely rational but rather biased according to the words presenting the choices. This rule can be explained via framing effect. The inconsistency of selections in equivalent choices with different wordings is the most observable evidence of framing effect. According to Levin, Schneider, and Gaeth’s paper written in 1998, there are three major types of framing effect: attribute framing, risky choice framing, and goal framing. Following parts of paper will describe the types of framing effects as well as the influential extant of framing effect on the logical decisions of people in real world.
Heuristics are often used in situations where uncertainty exists. They involve using short cuts or an educated guess in order to solve a problem. This technique can be useful for picking up on suspicious activity to conduct a stop and frisk, or for other low risk actions, but when they are used for more complicated and serious matters, is when it becomes a problem. Since these hunches are not factual, more based on rule of thumb, they have a higher possibility of being wrong. If an entire case is based off of a misleading hunch, than any work devoted to solving such case is not valid.
Many of the decisions one makes are heavily based on bias, past experience, peer pressure or wrong ideas. Decision making is a complicated algorithm that is affected a lot by the subconscious or peer pressure, although one is fully in charge of his decisions, study shows one’s decision is strongly distorted.
...s go about making judgments and choices. Both theories play an intrinsic role with behavioral decision making and have proven to be successful approaches for management (Shanteau, 2001).
Individuals make economic decision based on a variety of reasons. The rational is based on each individual’s need or desire for a commodity. People go through several decision-making processes before making the final decision and are often not conscious of the process. Obviously, decision- making covers a wide area, involving virtually the whole of human action. Often people are not conscious of the process.
