decision under uncertainty

Per economic theory, individuals choose among alternatives based on well-defined preferences. Mortgage lenders have been criticized for taking advantage of these biases by featuring monthly payments, obscuring charges and fees, emphasizing short-term benefits versus long-term costs or risks, imposing time constraints, and creating barriers to comparison shopping (Retsinas and Belsky 2008). Therefore, the action minimizing the expected loss is again the Bayes action, and the two formulations are equivalent from this standpoint. Patients commonly reveal negatively biased cognitive schemes (eg, Garety et al. For example, in the event that goals are not met, individuals who are promotion-focused may perceive failure as the absence of a desired outcome and hence feel dejection or disappointment. For example, in the submarine domain, the experts have the highest levels of uncertainty, whereas in the Weather domain they have the lowest. Here, subjects watched short video clips depicting two actors who manipulated objects either with or without cooperation (Backasch et al., 2013). The Weather data included novices (juniors and seniors in weather forecasting school) and experts, and the submarine data had only intermediates and experts (both were submarine officers with field experience, but to varying degrees). These tasks have been used in numerous studies in problem and pathological gamblers, and detect reliable impairments: Pathological gamblers fail to learn advantageously choice strategy, select more risky options, and prefer immediate rewards over delayed rewards. In the mortgage market, borrowers may fail to default ruthlessly or strategically because of loss aversion, leading them to be overly optimistic about house price appreciation (Bhutta et al. The lack of modulation was correlated with the degree of psychotic symptomatology. Edi Karni, ... Massimo Marinacci, in Handbook of Game Theory with Economic Applications, 2015. In support of this idea that there are recognition and resolution elements to uncertainty, one can divide a problem-solving session into two halves (early and late). The term "opportunity loss or regret" is most closely associated with: A. minimax regret. An extensive and growing body of research has examined the effects of emotions and affect specifically on information processing and decision making (for reviews, see Clore, Schwarz, & Conway, 1994; Delgado et al., 2011; Eagly & Chaiken, 1993; Epstein, 1994; Fiedler, 2000; Isen & Geva, 1987; Lazarus, 1999; Martin, 2000; Zajonc, 1980). In this context, many studies have focused on the investigation of theory of mind (ToM). Loomes and Sugden (1982) note that regret-theoretic preferences do not preserve first-order stochastic dominance in the sense of Hadar and Russell, but that statewise stochastic dominance is preserved. In our participant pool for that study, only fMRI involved all three performance levels. As an example, consultants often use visualizations of projects or designs as a method to force discrete choice. In an fMRI study, reduced ventromedial prefrontal reactivity was found in problem gamblers with comorbid substance dependence, compared to healthy controls, and the same effect was seen in substance-dependent participants without gambling problems, supporting a shared mechanism across the addictions. We specifically looked at what indicators were used to identify sources of uncertainty. Figure 17.3. It’s impossible to predict the future. Additionally, it is suggested that we may have learned the wrong lessons from some of our most complex and most important projects delivered under high uncertainty … Jack Meyer, in Handbook of the Economics of Risk and Uncertainty, 2014. Let pi be the marginal distribution on Xi of p. The independence condition which says that p∼q whenever pi=qi for all i implies an additive decomposition u(x1, …, xn)=u1(x1)+ … +un(xn) for outcome utilities (Fishburn 1970, p. 149). Cognitive biases support the generation and maintenance of delusions. How those opposing trends balance in aggregate will depend on the complexities of the task at hand. The mean-variance decision model is also discussed, first in Section 3.2 and then again briefly at the end in Section 3.6. Wolfram Elsner, ... Henning Schwardt, in The Microeconomics of Complex Economies, 2015. Loomes and Sugden begin by assuming that the bets are independent. Global change issues are complex and the consequences of decisions are often highly uncertain. K. Pauly, C. Moessnang, in The Neurobiology of Schizophrenia, 2016. The effectiveness of decision making may decline in situations of high stress, anxiety, or emotion (Janis & Mann, 1977; Keinan, 1987). A comparison of the two methods, using exactly the same set of images, often yields different results. As a result, individuals may incur additional costs to avoid losses relative to experiencing gains. 2001; Lee et al. Linearity in probabilities is directly associated with the independence axiom (Machina, 1987; as well the survey by Quiggin, 2013). In this case I assume that one of them will always be red and one of the green, and there is 50% chance of the outcome. In contrast to healthy subjects (A) and patients with major depressive disorder (B), patients with schizophrenia (C) did not show a modulation of amygdalo-hippocampal activation by an expected reward value (ERV) in an instrumental reward learning task. Another bias that relates to mortgage decisions is known as anchoring and adjustment. Recognizing and accommodating these changes provides the opportunity to increase decision making effectiveness. Since this function is concave, this solution to the St. Petersburg Paradox has been pointed to as the first representation of risk aversion in an expected utility decision model. We defined novices as those individuals having already learned enough of the task basics to be able to complete the analysis tasks on their own (e.g., analyze an fMRI dataset, make a weather prediction). One line of evidence suggests that patients with schizophrenia suffer from hyper-ToM, which is the tendency to perceive agency when there is none and which is assumed to result from an overactive ToM network (Abu-Akel and Bailey, 2000). This correspondence defines an action, that is an actions is a function a from Θ to Z. In sum, uncertainty and approximation have a complex relationship to expertise levels rather than a simple-linear trend relationship, and the relationship likely depends upon the ease in which uncertainty is detectable and resolvable in a given setting given available tools and strategies. There Are Three Possible Choices: High- Tech Development, Low-tech Development, And Do-nothing. Often, public participation data that is gathered piecemeal, or in an unstructured manner, is only of limited value under the best circumstances (NRC, 2008, p. 4). So the design of the process should consider implementation: how the process can inform both initial assessment and decision-making and ongoing analysis and action.” Therefore, we define clarity as the degree to which the process “informs decision-making and ongoing analysis” in the eyes of the sponsor and experts. An optimal action, or ‘Bayes’ action aB, is one that maximizes the expected utility, that is. Should a tail occur on the first toss, the gamble continues. Many studies have found that deluded patients tend to gather less information until they come up with a decision as compared to healthy subjects (ie, they jump to their conclusion) (Corcoran et al., 2008; Van Deal et al., 2006; see Ross et al., 2015 for a meta-analysis). 1998, Kahneman and Tversky 1996; Lichtenstein and Fischoff 1977, Prospect Theory, Asset Pricing, and Market Dynamics, Microscopic Simulation of Financial Markets, Journal of Behavioral and Experimental Economics, Journal of Economic Behavior & Organization. So, if regret considerations are important, the low-payoff bet will be chosen. Indeed, some expertise literature focuses on the amazing swiftness with which experts can see problems in terms of solutions features and solve problems (Chase & Simon, 1973; Chi, Feltovich, & Glaser, 1981; Gobet & Simon, 1996; Larkin, McDermott, Simon, & Simon, 1980). Decision Analysis Involving Continuous Uncertain Variables 4. Figure 3A presents the levels of uncertainty speech across the expertise levels in each domain, and Figure 3B presents the levels of approximation speech across the expertise levels in each domain. Figure 4 presents relevant uncertainty speech data from the fMRI domain. G. Parmigiani, in International Encyclopedia of the Social & Behavioral Sciences, 2001. The way the model works may be illustrated by considering the resolution of the common ratio effect proposed under regret theory. Correlation of Random Variables and Estimating Confidence 5. Standard approaches to decision-making under uncertainty require information about the likelihood of alternative states, how states and actions combine to form outcomes and the net benefits of different outcomes. This does not mean merely helping the project team choose among their favorite alternatives. If I cross what would be a left move on the picture, (route 2) then I can walk almost to the shop and then I have to cross another … Second, there is usually a host of factors that are currently unknown but that are in fact knowable—that could be known if the right analysis were done. There are a few statistically significant differences, but no consistent differences across the three domains. I can cross it one way or the other. (12 Points) Decision Under Uncertainty. The various strands of this critical movement form the topic known as ‘bounded rationality.’ This article sketches the historical roots and some current developments of this movement, distinguishing between attempts to extend the Savage Paradigm (‘costly rationality’) and the need for more radical departures (‘truly bounded rationality’). Indeed, experts in most domains deal with a very uncertain world, hence the large focus on, Moss, Kotovsky, & Cagan, 2006; Schunn & Anderson, 1999; Voss, Tyler, & Yengo, 1983, Corcoran et al., 2008; Van Deal et al., 2006. In all three domains, the differences by expertise level are small. The central role of this network for reacting to unpredicted stimuli and acting in uncertain situations has been supported by findings in healthy subjects, for whom increasing uncertainty led to increasing activation in the dorsal prefrontal, posterior parietal, and insular cortices (Huettel et al., 2005). Importantly, participants know a priori that the jars contain beads of two colors at different ratios (eg, the ratio of green and red beads is 80:20 in jar A and 20:80 in jar B). Authors reported elevated responses in the medial prefrontal cortex, temporo-parietal junction, and posterior superior temporal sulcus during the noncooperative (ie, less social) condition in patients with schizophrenia, which correlated with delusional symptoms. Several studies (e.g., Kalisch, Wiech, Herrmann, & Dolan, 2006; Ochsner & Gross, 2005) have shown that employing emotional regulatory strategies can reduce the intensity of a subjective feeling or emotion (negative and positive) and allow for a more controlled response to an emotionally charged decision-making situation. Since Tversky and Kahneman make the distinction between positive prospects2 and negative prospects, they suggest the following two-part power value function: where x is the change in wealth, and α, β, and λ are constants satisfying 0 < α < 1, 0 < β < 1, and 0 < λ. Cognitive biases can thus result in judgment errors and are not solely a function of lack of knowledge. I often have to walk from a parking lot to the shops in the city where I usually shop. decision making under certainty, risk & uncertainty Explain the difference between decision-making under certainty, risk and uncertainty. Authors reasoned that the observed increase in activation might be a result of greater ambiguity of the noncooperation condition for patients who tended to actively search for cues for cooperation and, consequently, to overattribute intention. In the Iowa gambling task (IGT), participants make a series of choices between four card decks, and the decks differ in the profile of wins and losses: Two decks are “risky,” associated with high gains on each trial, but occasional dramatic losses and two decks are “safe,” associated with lower wins and negligible losses. Similar results were provided by another study about probabilistic reasoning involving patients with schizophrenia (Paulus et al., 2003). The expected loss is. The percentage of segments (with SE bars) showing (A) uncertainty speech and (B) approximation speech as a function of domain and expertise levels. The actual life of an engineer and scientist is much less clear-cut. Professor Gilboa coauthored A Theory of Case-Based Decisions … In experiments with real large-scale bridge design project, and in workshops delivered to DoT representatives, for example, we have compared ratio-scale preference evaluation of the visualizations of design alternatives with forced choice, one-and-done voting. Frijda (1986) has affirmed the valuable input of emotions in helping decision-makers to prioritize goals and in generating a state of action readiness needed to respond to relevant concerns in a particular situation. Neuropsychologists have studied the impact of relationships between emotional control and reasoning capacities in relation to people's ability to resolve everyday problems (e.g., Frith & Singer, 2008; Rath, Simon, Langenbahn, Sherr, & Diller, 2003). It also surveys some implications of the departures from the “linearity in the probabilities” aspect of expected utility theory to game theory. The recipient of a Sloan Fellowship, among other awards, he has published articles in the leading economic theory journals, primarily on decision under uncertainty. In Chapter 8, Learning by Doing: Development of CAVE and SPI, we will demonstrate methods by which the disparate preferences of citizens can be understood in ways that allow higher overall value to be delivered to more people, but this is a far cry from claiming that everyone will get what they want. It is assumed that the initial, problem-orientation phase of decision making is primarily affective in nature. Healthy participants revealed activation in the amygdala and the medial prefrontal cortex during increased excitement. Decision-making under Uncertainty: Most significant decisions made in today’s complex environment are formulated under a state of uncertainty. See also Elicitation of Probabilities and Probability Distributions. The Hurwicz criterion computes a weighted value from the minimum and the maximum... Handbook of the Economics of Risk and Uncertainty. R. Radner, in International Encyclopedia of the Social & Behavioral Sciences, 2001. Recent research has emphasized the necessity of examining differences in processing based on more diverse sets of emotions, within positive and negative affective states. Savage proposed the adoption of a minimax loss criterion for statistical decisions, which he attempted (not entirely successfully) to reconcile with the EU approach. In this case, with prize probabilities of 0.05 and 0.04, the likelihood that both bets will pay off in a given state is 0.002. However, this model has been criticized as inadequate from both normative and descriptive viewpoints. In contrast, prevention-focused individuals may view the failure as the presence of unwanted outcomes, reacting in an agitated or threatening manner. … For contributions using nonlinear models, see Karni (1992) and Machina (2013). We have done this coding in all four science/applied science domains. The gamble continues until heads is first observed. This value function satisfies V′(x) > 0 for all x ≠ 0, V″(x) > 0 for x < 0, and V”(x) < 0 for (x) > 0, and is therefore S-shaped (see Figure 9.1) The convexity of the value function for negative x, and its concavity for positive x, is in accordance with the findings of risk seeking for negative prospects (x < 0), and risk aversion for positive prospects (x < 0). It is assumed that the initial, problem-orientation phase of decision making is primarily affective in nature. Evaluating clarity can be done by surveying professionals and agency officials about aspects of the process using a scorecard approach. But this approach can often create more problems than it solves. With objective probabilities, three basic axioms are necessary to obtain the von Neumann–Morgenstern theorem: weak order, independence, and continuity. This negative biasing seems to be related to activation changes in emotion-related areas, such as the amygdala (Heinz and Schlagenhauf, 2010). In a PET study in pathological gamblers compared to healthy controls, which enables the measurement of DA receptor binding during this decision-making task. Due to overconfidence, people often believe that they know more than they actually do, and this can have negative consequences. In situations that call for, De Martino et al., 2006; Martin & Delgado, 2011, Clore, Schwarz, & Conway, 1994; Delgado et al., 2011; Eagly & Chaiken, 1993; Epstein, 1994; Fiedler, 2000; Isen & Geva, 1987; Lazarus, 1999; Martin, 2000; Zajonc, 1980, Keltner, Ellsworth, & Edwards, 1993; Tiedens & Linton, 2001, Bodenhausen, Kramer, & Susser, 1994; Lerner, Goldberg, & Tetlock, 1998, Kalisch, Wiech, Herrmann, & Dolan, 2006; Ochsner & Gross, 2005, The Psychology of Learning and Motivation: Advances in Research and Theory, Chase & Simon, 1973; Chi, Feltovich, & Glaser, 1981; Gobet & Simon, 1996; Larkin, McDermott, Simon, & Simon, 1980, ). It is almost never possible to satisfy all stakeholders. The expected utility Uπ of action a is then the weighted average of the utilities of the possible consequences of the action, weighted by the probability of the corresponding state of nature. One way to realize how ignorant we are is … The fMRI, Weather, and Submarine cued-recall dataset provides an opportunity to look at expertise effects on rates of uncertainty and approximation across domains to look for consistent patterns. Crowdsourcing the Right Way. The decision … These biases may explain borrowers who fail to refinance higher-rate mortgages, despite favorable interest rates, credit quality, or equity advantages. The probability of heads occurring first on the nth toss of a fair coin is {1/2}n. Thus, the expected value of this gamble is given by ∑i=l∞(2i)(12i) which is not finite. However, more effective conversion of citizen values into decision support for agencies not only delivers higher net satisfaction from the viewpoint of those situated within the process, but supports more legitimate development and selection of alternatives under constrained circumstances.

Increasingly, public participation is viewed as an element of adaptive governance rather than as a one-time, one-way flow of information. Effective decision making under uncertainty is outlined and high reliability practices for decision making under uncertainty are tabulated. In the Iowa gambling task (IGT), participants make a series of choices between four card decks, and the decks differ in the profile of wins and losses: Two decks are “risky,” associated with high gains on each trial, but occasional dramatic losses and two decks are “safe,” associated with lower wins and negligible losses. Less attention is given to the question of stochastic dominance. Engineering Decision Variables – Analysis and Optimization 7. Conditions of uncertainty exist when the future environment is unpredictable and everything is in a state of flux. The focus in this chapter is on how risk aversion and risk are represented in various decision models. Suppose a person receives an outcome of size 2 if flipping a fair coin results in heads on the first toss. Bernoulli identifies a gamble that most persons would pay only a small sum to be allowed to participate in, but whose expected value is infinite. The paradox that Bernoulli is pointing out is that most persons are unwilling to pay more than a modest sum to participate in this gamble even though the expected value from participating in the gamble is infinite. Performing Engineering Predictions 6. Action i will be preferred over j if. For example, “To what degree did this information help you reach a solution you consider better?” (Dietrick et al., 2008). Taken together, the dysregulation of the amygdalo–hippocampal complex in particular and also dysfunctions in higher-order cortical networks involved in emotion regulation in general contribute to the well-documented abnormalities in emotion processing and the anticipation of a hedonic experience and therefore might represent a major neural correlate of emotional biases in schizophrenia. Decision theory can be broken into two branches: normative decision theory, which analyzes the outcomes of decisions or determines the optimal decisions given constraints and assumptions, and descriptive decision theory, which analyzes how agents actually make the decisions they do. This chapter reviews developments in the theory of decision making under risk and uncertainty, focusing on models that, over the last 40 years, dominated the theoretical discussions. This Decision Concerns Whether To Develop A New Product. However, much of the expertise literature making those claims focuses on well-defined problems such as simple physics problems that are purely education tasks rather than problems an expert would actually encounter. The decision-maker is not aware of all available alternatives, the risks associated with each, and the consequences of each alternative or their probabilities. An increasing sense of uncertainty reflects a changing environment that will impact the choices we make. Interaction of group and condition in healthy controls (HC) and chronically deluded patients with schizophrenia (Sz) during decision-making under uncertainty (d) and a counting (c) control condition. Formally. Ted Grossardt, Keiron Bailey, in Transportation Planning and Public Participation, 2018. For example, if frightening music is presented, then deluded patients often jump to conclusions even more (compared to healthy participants). Georges Dionne, Scott E. Harrington, in Handbook of the Economics of Risk and Uncertainty, 2014, Although the theory of decision making under uncertainty has frequently been criticized since its formal introduction by von Neumann and Morgenstern (1947), it remains the workforce in the study of optimal insurance decisions. The set of actions will be denoted here by A, with generic action a; the set of consequences by Z, with generic consequences z, and the set of states of the world by Θ, with generic element θ. In the prototypical formulation of decision making under uncertainty, an individual decision maker (DM) must choose one among a set of actions, whose consequences depend on some unknown state of the world. Decision makers often focus on or “anchor on” the information that they perceive to be the most important, and then adjust this evaluation when they encounter less important information (Hogarth and Einhorn 1992). Experts were those at the top performance levels. Cognitive biases are often accompanied and often aggravated by negative emotional biases. In contrast to nondeluded patients, patients with paranoid ideation showed increased physical stress responses but decreased activation of the amygdala and medial prefrontal cortex when exposed to fearful facial expressions. First, it is often possible to identify clear trends, such as market demographics, that can help define potential demand for future products or services. Across repeated draws, subjects get more information about the origin of the bead, which in turn increases the probability for a correct response. Another line of evidence for the role of emotional dysfunction in delusional symptoms comes from Williams et al. In words, to find the minimax action the DM considers each action in turn and computes the largest loss under any possible state of the world, for that action. 1991). Chapter 05S Decision Theory 5S-7 32. Tversky and Kahneman (1992) conducted a comprehensive experimental study of decision making under uncertainty. Bernoulli suggests diminishing marginal utility as a reason why this is the case. An action's consequences depend on the unknown state of the world, however, and each action yields a certain consequence corresponding to each state of the world. This is not the case if happy music is played (Moritz et al. This pattern was interpreted as a functional disconnection of cortical and subcortical networks as well as a disturbed interaction between the amygdala and the autonomic system, likely resulting in “hypervigilance” and misattributions. Given a suitably convex regret function, the first of these effects will dominate, so decision makers will prefer the lower-probability high-payoff bet. For example, people who do not know their credit rating are more likely to overestimate than to underestimate their credit quality. This approach does not requires specifying a probability distribution π over the states of the world. But let us be very clear. The DM then chooses the actions with the smallest maximum loss. Indeed, experts in most domains deal with a very uncertain world, hence the large focus on decision making under uncertainty within naturalistic decision-making research. Attenuated prefrontal activation during decision-making under uncertainty in schizophrenia: a multi-center fMRI study. Most significant decisions made in today’s complex environment are formulated under a state of uncertainty. As explained in Chapter 1, and developed in more detail in later chapters, it also includes clarifying the nature of the problem to be solved and the value system to be used in evaluating potential solutions. A number of such general indicators could be found. Nonetheless, a large number of fundamental results in insurance economics have been derived from the linear expected utility model. However, evidence suggests individuals often exhibit a significant status quo bias: the more options available, the stronger the bias for the status quo; the stronger an individual’s preference for a selected alternative, the weaker said bias (Samuelson and Zeckhauser 1988). Available strategically relevant information tends to fall into two categories. The second part reviews theories of decision making under uncertainty that depart from the sure thing principle and model the phenomenon of ambiguity and ambiguity aversion. In addition, the underrecruitment of brain areas related to social processing in response to social stimuli seems to underlie the reduced ability to discriminate between social and nonsocial events. Such distinctive emotional reactions tied to regulatory mechanisms are assumed to serve as information signals and impact the individual's encounter with the decision-making situation. In most cases, consumers fail to adequately account for the additional charges, or they ignore them all together (Bertini and Wathieu 2008; Morwitz et al. Conditions of uncertainty exist when the future environment is unpredictable and everything is in a state of flux. Vanessa G. Perry, in Introduction to Mortgages & Mortgage Backed Securities, 2014. The Society for Decision Making Under Deep Uncertainty is a multi-disciplinary association of professionals working to improve processes, methods, and tools for decision making under deep … (2004), who compared patients with and without delusions with healthy participants while they watched fearful and neutral faces. Even the simplest decisions carry some level of uncertainty. It is rational and adaptive to account for emotional reactions and assume that the experience will inform individual decision-making routines in the future. The IGT has also been implemented in several neuroimaging studies in problem gamblers. The IGT assesses, Participation Performance Frameworks, With Examples From Structured Public Involvement or SPI, Transportation Planning and Public Participation, International Review of Research in Developmental Disabilities, Argyle, 1991; De Martino, Kumaran, Seymour, & Dolan, 2006; Parkinson & Simons, 2009, Frith & Singer, 2008; Rath, Simon, Langenbahn, Sherr, & Diller, 2003, ).
