Decision-Making and Decision Anomalies

A rational individual is expected to have consistent preferences, meaning they would consistently rank their options and choose the best alternative based on this ranking. The presentation or definition of options should not affect their choice behavior.

In the experiment, when the outcomes were framed positively (Programs A and B), participants preferred the certain outcome (Program A). When the outcomes were framed negatively (Programs C and D), they preferred the risky option (Program D). This change in preferences between the two groups illustrates the framing effect's impact on decision-making.

The two systems of human thinking and reasoning are known as System 1, the Automatic system, and System 2, the Reflective system. System 1 is characterized as effortless, fast, emotional, and operates based on associations and habits. System 2 is effortful, slow, neutral, flexible, and rule-governed.

Heuristics are mental shortcuts or rules of thumb that enable individuals to make decisions quickly and with minimal effort by utilizing readily available information. While they facilitate efficiency in decision-making, they can also lead to systematic errors or biases, particularly in complex or unfamiliar situations.

While heuristics enable quick decision-making, they can also lead to systematic errors or biases. This is because these shortcuts often rely on oversimplified information processing, ignoring relevant data or failing to accurately weigh the importance of different factors, leading to decisions that might not be optimal or rational.

The status-quo bias is the tendency of individuals to prefer maintaining their current situation over making changes, even when switching could potentially maximize their utility. This bias is evident when people overvalue items they own simply because they own them, often setting a higher selling price than they would be willing to pay to purchase the same item.

Mental effort contributes to status quo bias as making decisions and considering changes require significant cognitive work. People may avoid this effort, preferring to maintain their current situation rather than expend the energy needed to assess the benefits and drawbacks of different actions.

In behavioral economics, the status quo refers to the current state of affairs or the existing situation. It represents the baseline condition against which changes are measured or considered.

Transaction cost refers to the expenses incurred when changing from one alternative to another, including both financial costs and non-financial burdens such as time or effort.

The Endowment Effect is a cognitive bias where individuals value something they own more highly than a similar item they do not own, simply because they possess it. This effect can lead people to overvalue their current goods or services, making them reluctant to trade or switch to better alternatives.

Procrastination is the act of delaying or postponing tasks or decisions, leading to the automatic selection of the status quo by default. This behavior often arises when faced with complex alternatives that are difficult to compare, prompting individuals to maintain their current situation rather than making an effort to evaluate other options.

The representativeness heuristic leads people to estimate the likelihood of an event by comparing it to an existing prototype or similar event. This can result in high probability estimations for events that closely resemble the prototype and low estimations for those that do not, often disregarding actual statistical probabilities or base rates.

Base rate neglect occurs when individuals disregard or undervalue the underlying frequencies or probabilities (a priori probabilities) of outcomes in a population. Instead, they overemphasize specific information or similarities to prototypes, leading to skewed probability estimations that can deviate significantly from rational predictions.

The Law of Small Numbers refers to the erroneous belief that small samples accurately represent the general population. This misconception leads people to make incorrect decisions by assuming that the characteristics or trends observed in a small sample will mirror those of the larger population, disregarding the statistical principle that larger samples are more likely to approximate the overall mean

The Gambler’s Fallacy is the mistaken belief that if a particular outcome occurs more frequently than normal during a certain period, it will happen less frequently in the future. It's related to the Law of Small Numbers because it arises from the incorrect assumption that short-term outcomes in random events must balance out in the immediate future, ignoring the independent and random nature of each event.

The Hot Hand Fallacy is the belief that success in a random event leads to a higher probability of success in subsequent attempts. It manifests in perceptions that a basketball player on a scoring streak has a higher chance of scoring on the next shot, or that a lottery ticket seller who has sold a winning ticket once is more likely to sell another, despite each event being independent and random.

The availability heuristic is a cognitive shortcut that involves estimating the likelihood of events based on how easily examples come to mind. This heuristic can lead to misjudgments about the frequency or probability of events because people tend to overestimate the likelihood of occurrences that are more memorable or vivid, such as shark attacks or plane crashes, regardless of their actual statistical rarity.

Mental accounting is the cognitive process individuals use to organize, evaluate, and keep track of their financial activities. Richard Thaler defines it as the set of cognitive operations used by individuals to assess, manage, and reflect on their financial transactions, incorporating not just the numerical aspects but also the psychological, emotional, and social factors that influence financial decision-making.

Labeling in mental accounting refers to how individuals categorize their financial resources, expenditures, and savings. By assigning labels to different types of financial data, such as designating funds for specific purposes (e.g., housing, food, savings) or classifying income into categories (e.g., regular income vs. bonuses), individuals can organize their finances more effectively, allowing for more targeted and thoughtful spending and saving behaviors.

Prospect Theory's Value Function, as introduced by Kahneman and Tversky, impacts individuals' mental accounting by establishing that gains and losses are evaluated relative to a reference point, and not in absolute terms. This theory explains why losses tend to impact individuals more negatively than equivalent gains provide positive feelings, due to loss aversion and diminishing sensitivity. The Value Function helps illustrate why, in mental accounting, the context and framing of financial decisions significantly affect how outcomes are perceived and valued.

Loss aversion, a key component of the Value Function in Prospect Theory, influences purchasing behavior by making the pain of losing money feel more significant than the pleasure of acquiring goods. This can lead to a conflict in decision-making, as the perceived loss (spending money) may outweigh the gain (acquiring a product), potentially suppressing spending behavior unless the perceived value of the product significantly exceeds the cost.

The effectiveness of breaking down gains into the smallest possible increments is limited by the potential for self-deception and the "peanuts effect." People are generally resistant to intentional self-deception in manipulating their perceptions of gains and losses. Additionally, the peanuts effect refers to the tendency to disregard trivial amounts that fall below a subjectively determined threshold, indicating that not all small gains will significantly impact one's perceived utility. These factors ensure that only spontaneously occurring and subjectively significant segregations or integrations of financial outcomes effectively enhance utility.
