As a recipient of many prestigious awards, including a Nobel Prize, psychologist Daniel Kahneman has worked rigorously for nearly 45 years to advance the way in which we understand human cognitive processes. Kahneman and his longtime colleague, Amos Tversky, began working together in the 1970s and almost immediately made an impact within the fields of psychology and behavioral economics. These contributions centered around the notion of human irrationality, or the basis we subconsciously use to make decisions each day. Beginning with their discovery of human decision making heuristics and biases, Kahneman and Tversky went on to uncover many intuitive theories that helped evolve the field of behavioral economics into what it is today.

One of his original publications is titled, Availability: A Heuristic for Judging Frequency and Probability. Written by Kahneman and his long-time colleague Amos Tversky, the article highlights their initial conclusions about errors in our decision making. This paper explored a judgmental heuristic where a person assesses the frequency or probability of events by way of availability (Tversky & Kahneman, 1973). In other words, how easy common certain instances come to mind. They suggested a large contributor is our reliance on the availability heuristic, which is judging a situation based off of examples from a similar situation (Tversky & Kahneman, 1973). For example, assume one enjoys shopping at Costco and they have gone to the same Costco once a week for the last 10 years. Therefore, they are extremely familiar with the general layout of that specific store. However, this person is on vacation and they visit the Costco in their vacation spot for the first time. The person arrives and, in a search for produce, walks to the location it would be in the store they are familiar with. In the new store it may or may not be in the same location. This example illustrates our vulnerability for error when using the availability …show more content…
Anchoring occurs when individuals make judgments based off of an initial starting point. To demonstrate anchoring effect, the authors conducted a simple study in which subjects were asked to estimate the percentage of African countries in the United Nations. For each quantity, a number between 0 and 100 was determined by spinning a wheel of fortune in front of the participants. Participants were then required to state whether the number the wheel landed on was higher or lower than the percentage, and then to estimate the value of the quantity by moving up or down from a given quantity (Tversky & Kahneman, 1974). Different participant groups were provided with different numbers, which always had a marked effect on the answer given (Tversky & Kahneman, 1974). Therefore, the authors concluded that answers derived from this heuristic are highly dependent on the starting point. Furthermore, as a result of anchoring, people will be subjected to overestimate probability in some problems and underestimate probability in others (Tversky & Kahneman, 1974). Similarly, the authors conclude that the cognitive biases that result from reliance on judgmental heuristics, such as representativeness, anchoring, or availability are useful and somewhat reliable, but tend to lead to systematic
The article, “Unnatural Selections” by Barry Schwartz is an inspirational article that shows us all of the default choices that we take for granted in this world. He uses several examples to help give you the overall impression of the article. Along with the examples, Barry creates logic and emotion by the writing style he uses. He creates logic and emotion in his article by using persuasive elements such as evidence and reasoning. Barry Schwartz is a highly known professor of psychology, and has written several books. Therefore, we can be convinced that we are able to trust him as an author. He makes valid points and he does a magnificent job of persuading the readers into believing what he says with his examples.
In terms of the anchoring bias, regularly revisit of the original decision based on the newly gathered data needs to be set up within the organization. Additionally, the decision maker should avoid the Confirmation Trap in which Bazerman and Moore (2009) argues that people tend to seek information that confirms their expectations and hypotheses. To recognize the bias, Mike Francis could
In a decision-making problem, anchoring effects occur when a seemingly trivial factor serves as a starting point for estimations
In this article, the author explains why it is difficult to find the idealist man in today’s society. This piece was written by Kay S. Hymowitz and published in the Wall Street Journal on February 2011. The purpose of this essay is to inform women about “where the good men have gone”, due to the fact they are all becoming “guys” instead of men. When Hymowitz states this, she is referring to a stage between a boy and a man. The author provides evidence telling how men in their twenties have decreased and the amount of “guys” have increased over a period of time. Also, this article could strike up conversation about how the economy has changed by the increase in female roles and decrease in male roles.
The Emotional Repercussion on Decision Making “It was no longer a question that could be decided by an act of pure reason. Some irrational and powerful force was resisting” (O’Brien 49). Emotion is often separated from intellect and described as distinguished from reasoning. In contrast, the decisions we make are often based on emotion and intellect, rather than solely one or the other. By examining decisions made in stories and your own life experiences, whether vitally important to the existence of the human race or ordinary everyday choices, you can infer that emotion rather than intellect plays a more important role in decisions.
Two phenomena- hindsight bias and judgmental overconfidence- illustrate why we can’t rely solely on intuition and common sense.
One thing which stood out in the text involving both of their ideas was the fact that Tversky had once thought of Kahneman to not be entirely accurate on his ideas. He had questioned Tversky on the basis that peoples’ opinions are subjective; that they differ person to person. An example of this was the coin toss discussed in chapter three of the text. Relating to the coin toss example, the idea that many made assumptions based off of ideas that are insignificant was of great importance and lead to a rejection by both Kahneman and Tversky on the effectiveness of predicted outcomes. In the text, the author states, “Even the fairest coin, given the limitations of its memory and moral sense, cannot be as fair as the gambler expects it to be”. This involves the idea that even when one is certain of the reasoning behind their assumptions, it is logical to assume that everything will not fit the expected outcomes of the reasoner behind it, and their attempt at directly relating the two
The first area was the availability heuristic section. There were two biases that indicated whether or not you were making the right decision. The first was ease of recall, or the fact that we tend to decide things based on what comes to mind easily. The second was retrievability, the fact that we base decisions on the frequency of a particular pattern or event. We base many of our decisions on these two concepts.
Availability heuristic can be defined as making a choice based on immediate and easy examples that comes to the mind more easily when evaluating a decision. Even though availability heuristic has many pros such as saving time when making a choice, it does come with cons. This is because the availability heuristic distorts our understanding of real threats and risks. For example, Tom is a 10-year-old boy that adores puppies and loves playing with them. One day he saw a puppy bite its owner. Due to this small incident, Tom avoids playing with puppies even though the likelihood of it happening is slim. Since this heuristic draws from immediate and easy examples, it uses system 1 to evaluate our decisions. As we already know system 1 can lead to a lot of incorrect assessments in comparison to system 2.
This week’s reading Predictably Irrational was very valuable, and informative. While coming up with so many ways of thinking when it comes to behavior, I had no idea even existed. We talked last week about being rational, but this week and this week’s reading it discussed more about irrational, and predictable behavior. At the end of this summary I hope to have showed and understand the difference when it comes to irrational and predictable theories that can disrupt behavior, and decision making.
In studying framing effects, Kahneman references the following properties: accessibility and rationality. Accessibility is how efficient a person can determine the true value of an object or idea. For example, consider a person driving, but they have forgotten their spectacles. There is an approaching stop sign, however, with the driver’s impaired judgement, they cannot accurately predict how quickly the brakes need to be engaged. The driver’s accessibility to the distance between the car and stop sign is low. Consider the same situation, but with the driver in possession of their spectacles. In this situation, the driver’s accessibility to the distance is higher. Kahneman presents a variation of this dilemma (Problem 1 – The Asian Disease)
This distinctive book called, “Thinking, Fast and Slow” by Daniel Kahneman, is one of very few exquisite readings I’ve completed so far. Daniel Kahneman is a psychologist in Princeton University, and due to his research, he won a Nobel Prize in 2002 in economics. In the beginning of his book, he speaks of our cognitive System 1 and System 2 ways of thinking. System 1 generates feelings, impressions, and memory. It is very instinctive, automatic, and is considered quick thinking. System 2 on the other hand, is alert during complex problem solving, while dealing with facts and knowledge, and is attentive while working with difficult calculations. For example, a problem such as 24 x 13, this takes more time and knowledge to figure out (System 2), rather then recognizing an emotion from face expressions (System 1). When System 1 is strained, your System 2 steps in to help you process through that specific instant. Now aside from the psychological portion of this book, Mr. Kahneman divulges about a consolidated economic analysis with elemental intuitions from the psychological perspective; such as, luck and skill, overconfidence, risks in the stock market, factors of success and the decision making process. This book is overall concluded with the understanding of behavioral economics, which is the social and cognitive components on economic decisions that are defined by individuals and have consequences that reflect from making those decisions and taking those risks.
According to both Thaler and Sunsteins most human beings do not make decisions that are characterized in the elementary economics textbooks. However, the decisions should be along rich suggestions that enable people to come up with better choices for both ourselves and the society. Various people are likely to be surprised after learning that conditions and the setting in which individuals make the decisions normally tend to influence the choices that are made. This tendency is also likely to affect the decisions that have more significant consequences. This may include for instance how much a family saves and how they also invest, the kind of mortgage they are
The documentary, Mind Over Money, discusses the impact of emotions on financial decisions. Our behavior is bizarre when it comes to money. This video clearly shows this effect in its first example. When a 20-dollar bill was auctioned off, two buyers paid over the bill’s value. People do not use the information they should not be using, but use other information that is said to be crazy to use. The University of Chicago has given rise to the most Nobel prize winners in economics in the world. Here, the theory of economics shows that having rational behavior is one of the most relied on model of economics. Behavior is a very important concept since people are seen to work in their own self-interest.
Behavioural economics is the study of the effects that psychology has on the decision making of the economy. This tends to be the way that people think and feel when they are spending money on a certain good or service. The great economist Adam Smith was the first follower of this idea through his book “The theory of moral sentiments” which dates back to 1759. However, it took over 100 years to get a more clarified meaning of how big of a role the psychology of a buyer plays in economics. In behavioural economics there are seven basic principles which all contribute to the decision making process. Behavioural economics can explain how people will react to different situations such as times when there are no economic problems and times when
