DECISIONS‚ we make mistakes. We all know this from personal experience‚ of course. But just in case we didn’t‚ a seemingly unending stream of experimental evidence in recent years has documented the human penchant for error. This line of research—dubbed heuristics and biases‚ although you may be more familiar with its offshoot‚ behavioral economics—has become the dominant academic approach to understanding decisions. Its practitioners have had a major influence on business‚ government‚ and financial markets

Behavioural Finance Martin Sewell University of Cambridge February 2007 (revised April 2010) Abstract An introduction to behavioural finance‚ including a review of the major works and a summary of important heuristics. 1 Introduction Behavioural finance is the study of the influence of psychology on the behaviour of financial practitioners and the subsequent effect on markets. Behavioural finance is of interest because it helps explain why and how markets might be inefficient. For more information

This could be due to mental resources being highly valued and limited‚ and cognitive miserliness occurs out of efficiency (Fiske & Taylor‚ 1984). Tversky and Kahneman (1974) proposed 3 types of heuristics: representativeness‚ availability and anchoring. We will use the representativeness heuristic to illustrate the model. This model suggests that individuals typically do not act like scientists who rationally analyse information in daily life. Instead‚ individuals are more inclined to act as

The research has focused on two fundamental types of thinking. On the one hand‚ there’s ’heuristic processing’‚ which involves very shallow thought and is based on very simple rules: 1) buy what you recognize‚ 2) choose what you did last time‚ or 3) choose what a trusted source suggests. This requires comparatively little effort‚ and involves

Pitfalls and Limitations of Decision Making Heuristics and Biases: ‘People rely on a limited number of heuristic principles which reduce the complex tasks of assessing probabilities and predicting values to simpler judgmental operations.’ (Kahneman et. al‚ 1974) Heuristics are cognitive shortcuts or ‘rules of thumb’ used to simplify the decision making process. Heuristics result in good decisions and their main asset is that they save time. Most of the heuristics are used by people with specific cognitive

Regret aversion bias: People make decisions made on the anticipated risks. They don’t want to become the active agent in a wrong decision. A major study was done to understand this bias. A flu epidemic has hit your community. This flu can be fatal for children under the age of three. The probability of a child getting the flu is 1 in 10‚ and 1 in 100 children who get the flu will die from it. This means that‚ statistically speaking‚ 10 out of each 10‚000 children in your community will die. A vaccine
