We review the literature to identify common problems of decision-making in individuals and groups. We are guided by a Bayesian framework to explain the interplay between past experience and new evidence, and the problem of exploring the space of hypotheses about all the possible states that the world could be in and all the possible actions that one could take. There are strong biases, hidden from awareness, that enter into these psychological processes. While biases increase the efficiency of information processing, they often do not lead to the most appropriate action. We highlight the advantages of group decision-making in overcoming biases and searching the hypothesis space for good models of the world and good solutions to problems.

The figure shows that the reliability of a pooled estimate saturates when the pooled information is correlated. In the near future, we will know whether consumers embrace their product.

Rubinstein and Thomas A. Bibliographic record. This is a jewel of a book: most informative, insightful and, in several respects, even endearing. This reviewer feels that the authors have achieved a scintillating success both in looking at this experiment openly, critically and in-depth on the basis of years of superb research, and in conveying their results and judgments in a most readable and lively language. The issues at stake stem from the fact that Saturn is often hailed as the boldest expression of a new labour relations model—in the United States at the least.

The key question the authors seek to answer then is to what extent Saturn has been a success. The ideas behind Saturn go back a half-century. During the five start-up years prior to , examples of critical union input into key decisions included product development, selection of suppliers, marketing and retailer relationships, work force selection, and training and development.

In addition to several features of lean production, Saturn was also designed to embody a stakeholder firm and networked organization. The inner workings of this partnership in action have been analyzed through extensive and conceptually rigorous field research. This has generated a wealth of information and led the authors to four main conclusions.

A key factor in their effectiveness is the quality of support by module advisors. Teams do best under the following conditions: 1 when the module advisors communicate well with their peers, and this is an area where representative advisors do well; 2 when the two advisors balance the time they spend on people and production issues, such balance not being the same thing as equal time; and 3 when there is Kochan , Ithaca, N.

However, it is often the case that the decision-making process is less formal, and might even be implicitly accepted. If you need to make decisions in a group or team, it's the rhythm of success. Disaster almost struck the first week, when all but one of the first 16 cars he sold had bad engine antifreeze that had been delivered by a Saturn supplier. It was a remarkable, even revolutionary document, taking Saturn beyond the Japanese in establishing joint decision making. If there is no structure among the rest of the group, you may find that you have a bunch of individuals coming to you with various ideas and opinions — leading to confusion and chaos. A decision rule is the GDSS protocol a group uses to choose among scenario planning alternatives.

This may seem somewhat arcane: surely it's the brilliance of their ideas, or the courage of their decisions that set high-performing teams apart? Success in team-based decision-making is built on the mundane as with so much else in leadership. That's it. That's the rhythm of successful team-based decision-making. Data; debate; decide or defer. Say it over a few times and it starts to sound like a drumbeat--and that's just what it is, the underlying drumbeat to the decision-making discussions of a high-performing team:.

High-performing teams start with data. Not anecdote, not pain points, not speculation, not opinion--data. That's not to say that the alternatives are valueless--anecdote, pain points, speculation and opinion are all valid ways to uncover candidates for discussion--but once something gets on the agenda, the only place to start is with consideration of hard data.

No hard data, no discussion. How much would that principle shorten most of your team meetings? Debate is at the heart of high-quality team-based decision-making--but not just any sort of free-for-all debate. High-performing teams first of all only debate the underlying data as we've already seen , but most importantly, they do so dispassionately, objectively, and with only the good of the enterprise at heart. Think this sounds a little too altruistic, a trifle unrealistic to expect from your hard-charging, passionate team members?

Try using the 20 most powerful words in business as a starting point. It's time to fish, or cut bait--you've assembled the data, debated it, and now it's time to make a decision. Sounds easy, but most teams and groups flunk this part of the process. Simply by letting the debate stage rumble on for so long that when the time comes to make a decision, everyone in the room is tired, confused, or both--or worse, the debate goes on for so long that there is no time to make a decision. Here's a simple tip from high-performing teams: agree in advance on the precise time at which the decision will be made.

The social identity approach suggests a more general approach to group decision-making than the popular groupthink model, which is a narrow look at situations where group and other decision-making is flawed.

Social identity analysis suggests that the changes which occur during collective decision-making is part of rational psychological processes which build on the essence of the group in ways that are psychologically efficient, grounded in the social reality experienced by members of the group and have the potential to have a positive impact on society.

Decision-making in groups is sometimes examined separately as process and outcome. Process refers to the group interactions. Some relevant ideas include coalitions among participants as well as influence and persuasion. The use of politics is often judged negatively, but it is a useful way to approach problems when preferences among actors are in conflict, when dependencies exist that cannot be avoided, when there are no super-ordinate authorities, and when the technical or scientific merit of the options is ambiguous.

In addition to the different processes involved in making decisions, group decision support systems GDSSs may have different decision rules. A decision rule is the GDSS protocol a group uses to choose among scenario planning alternatives. Plurality and dictatorship are less desirable as decision rules because they do not require the involvement of the broader group to determine a choice. Thus, they do not engender commitment to the course of action chosen.

An absence of commitment from individuals in the group can be problematic during the implementation phase of a decision. There are no perfect decision-making rules. Depending on how the rules are implemented in practice and the situation, all of these can lead to situations where either no decision is made, or to situations where decisions made are inconsistent with one another over time.

Sometimes, groups may have established and clearly defined standards for making decisions, such as bylaws and statutes. However, it is often the case that the decision-making process is less formal, and might even be implicitly accepted.

Social decision schemes are the methods used by a group to combine individual responses to come up with a single group decision.

There are a number of these schemes, but the following are the most common:. There are strengths and weaknesses to each of these social decision schemes. Delegation saves time and is a good method for less important decisions, but ignored members might react negatively. Averaging responses will cancel out extreme opinions, but the final decision might disappoint many members.

Plurality is the most consistent scheme when superior decisions are being made, and it involves the least amount of effort. But, it might be difficult for the group to reach such decisions. Groups have many advantages and disadvantages when making decisions.

Groups, by definition, are composed of two or more people, and for this reason naturally have access to more information and have a greater capacity to process this information.

Some issues are also so simple that a group decision-making process leads to too many cooks in the kitchen: for such trivial issues, having a group make the decision is overkill and can lead to failure. Because groups offer both advantages and disadvantages in making decisions, Victor Vroom developed a normative model of decision-making [8] that suggests different decision-making methods should be selected depending on the situation.

In this model, Vroom identified five different decision-making processes. The idea of using computerized support systems is discussed by James Reason under the heading of intelligent decision support systems in his work on the topic of human error. James Reason notes that events subsequent to The Three Mile accident have not inspired great confidence in the efficacy of some of these methods.

In the Davis-Besse accident, for example, both independent safety parameter display systems were out of action before and during the event.

Decision-making software is essential for autonomous robots and for different forms of active decision support for industrial operators, designers and managers.

Due to the large number of considerations involved in many decisions, computer-based decision support systems DSS have been developed to assist decision-makers in considering the implications of various courses of thinking. They can help reduce the risk of human errors. Groups have greater informational and motivational resources, and therefore have the potential to outperform individuals.

However they do not always reach this potential. Groups often lack proper communication skills. On the sender side this means that group members may lack the skills needed to express themselves clearly.

On the receiver side this means that miscommunication can result from information processing limitations and faulty listening habits of human beings.

In cases where an individual controls the group it may prevent others from contributing meaningfully.

We review the literature to identify common problems of decision-making in individuals and groups. We are guided by a Bayesian framework to explain the interplay between past experience and new evidence, and the problem of exploring the space of hypotheses about all the possible states that the world could be in and all the possible actions that one could take.

There are strong biases, hidden from awareness, that enter into these psychological processes. While biases increase the efficiency of information processing, they often do not lead to the most appropriate action. We highlight the advantages of group decision-making in overcoming biases and searching the hypothesis space for good models of the world and good solutions to problems. Diversity of group members can facilitate these achievements, but diverse groups also face their own problems.

We discuss means of managing these pitfalls and make some recommendations on how to make better group decisions. Most decisions have to be made in the face of uncertainty and in the absence of immediate feedback. The purpose of this paper is to review the scientific literature in order to identify pitfalls that decision-makers—both individuals and those making decisions in groups—should be aware of and to make recommendations that can help groups make better decisions.

Our review will mostly be concerned with small groups who agree on the problem to be solved, such as panels and committees, although many of the phenomena that we consider can also be observed in large groups. The term intuitive is important; it reminds us that we are not conscious of most of our cognitive processes, which happen automatically and are simply too fast to reach awareness. We will often refer to the Bayesian distinction between past experience prior and new evidence likelihood.

We will also refer to the need to explore the hypothesis space from which we select an action. In doing so, our main aim is to understand how decisions can go wrong.

Details of the Bayesian approach can be found in appendix A. It is important to strike the right balance between, on one hand, past experience and perceived wisdom and, on the other hand, new evidence.

In the middle of the last century, doctors sent large numbers of children to hospital to have their tonsils and adenoids removed. Even when we make decisions on our own, information often comes from other people. To use this information appropriately, we need an estimate of the reliability , known as precision in the Bayesian framework, of our sources. The confidence with which others transmit information can be a useful marker, but it can also be misleading, even when there is no intention to deceive.

These dangers are present even when evaluating our own judgements. In many situations, the confidence we feel might not be a good guide. The landscape represents a probability distribution over the goodness of possible actions where the highest probability indicates the best action.

But how can we find this peak? Exploring the landscape of possible actions. The peak indicates the best action.

We sampled the height of the true probability distribution, akin to remembering how good an action was or asking a friend for their advice about which action to take. When we think we know enough, or are running out of time, we exploit our current knowledge to choose the action that we think will achieve the best outcome.

There are many cases where we do not have sufficient knowledge to make a good decision. Of course, if we have an exaggerated opinion of the adequacy of our current knowledge, then we may fail to seek more information. We have already mentioned the observation that some doctors used coronary angiography inappropriately [ 12 , 13 ]. If they had collected exercise data they would have found that angiography was unnecessary.

For example, rapidly recognizing an enemy, or a predator, leads to the good decision to take evasive action. There are other kinds of biases too, which depend on individual experience. For example, one can imagine a culturally dependent bias to stand on the left side of escalators e. While a useful instinct when in the context in which the bias was learnt, the bias can be offensive when in a new context where it is customary to stand on the right e.

Osaka or London. We will now consider some of the ways in which individual decisions can go wrong, and then discuss how groups can, sometimes, overcome these shortcomings. This mode of decision-making is the most typical of the workings of small groups. A common source of bad decisions is inappropriate prior beliefs.

If we have a strong prior belief in a hypothesis, then we need huge amounts of conflicting evidence to change our mind. Conversely, if we have a weak prior belief in a hypothesis, then we need huge amounts of supporting observations to believe it. For example, most scientists do not believe in extra-sensory perception e. While perhaps sensible in the case of extra-sensory perception, such weak prior beliefs have hindered scientific advances in the past.

It is not the case that faith in prior beliefs is a bad thing. Prior beliefs reflect past experiences with the world, either on an evolutionary or an individual time scale, and we greatly benefit from these. It is also not the case that new evidence should be distrusted on principle, because it is imperative that we adapt to new situations.

However, if we are to update our beliefs about the world appropriately, we need to be able to interpret the new evidence correctly. Here is an example from the history of science. When Galileo first viewed Saturn through a telescope in , he did not have a good model to explain what he saw. Misinterpreting new evidence. For example, after reading the leaflet for a prescribed medicine, we might overestimate the probability that a physical symptom is due to an adverse side effect.

By contrast, a doctor with years of experience prescribing the medicine might underestimate that very same probability. In this example, the patient overweights the new evidence, whereas the doctor overweights their past experience. In a typical psychological study, people would be asked to indicate their confidence in different judgements e.

The first one is resolution which characterizes the extent to which people's low and high confidence can discriminate between their incorrect and correct beliefs. Calibration in particular is subject to biases. Many problems require a depth of thinking that is beyond our cognitive powers. Even a simple game like tic-tac-toe can unfold in thousands of different ways.

In , Barbra Streisand filed a lawsuit to prevent the online posting of a photo of her home. At first sight, this seems to be the appropriate way to prevent unwanted material being made public. We believe that if unwanted behaviour is punished then it will cease. Prior to the lawsuit, only six people had downloaded the photo, two of them being Streisand's lawyers. Model-free strategies proceed by storing the outcomes of past actions and then acting upon these values in a habitual manner.

For example, a model-free player of tic-tac-toe might always seek to occupy the centre of the grid, because such behaviour has been rewarded in the past. By contrast, model-based strategies proceed by building and updating a model of the world; a model-based player of tic-tac-toe would not rely on old habits, but draw on an internal model of their opponent, imagining and assessing their future moves.

This requirement is, however, rarely satisfied. Even the state of the decision-maker may change, such that the future state to which the decision is relevant is not the same as the state when the decision had to be made.

Another heuristic solution to the complexity problem is to consider only a subset of hypotheses about the world and possible actions. When we do engage in forward planning, we may still use sampling from memory to inform some of the computations, such as estimating the expected value of an action. This strategy may, however, lead to distorted estimates if the sampling is biased. This bias may come about if, when building expectations from memory, we sample outcomes we like, but ignore outcomes we do not like.

As a result, we may underestimate the probability of undesirable outcomes, such as illness resulting from smoking, and overestimate the probability of desirable outcomes, such as winning the lottery or our new restaurant being a hit. Many of the problems of individual decision-making can be mitigated if individuals join with others to make decisions in a group.

We will consider group scenarios where people work together or independently. However, in the Recommendations section, we will mention some situations in which a group chair or leader can help mitigate the problems specific to group decision-making. For example, pooling unbiased but noisy numerical estimates causes uncorrelated errors to cancel out and therefore increases the precision of the pooled estimate see appendix B1.

Here, estimation errors may be uncorrelated, because people base their estimates on different past experiences or new evidence. For some domains, the method used need not be complex. This majority rule may be perceived as the fairest solution if group members have very different preferences. However, the outcome of this process critically depends on the reliability of the information upon which individual opinions were based.

But how should reliability be assessed? Weighting by reliability. The figure shows that the reliability of a pooled estimate is higher when each individual estimate is weighted by its reliability weighted averaging than when assigning equal weights to all individual estimates simple averaging.

In this simulation, we assumed that the individual estimates varied in terms of their reliability and were uncorrelated. See appendix B2 for mathematical details. The reason revealed in these studies is that discussion involves a recalibration of markers of reliability. By means of such recalibration, we can together increase the probability that no opinion is assigned undue weight.

Groups also outperform individuals in economic games e. Exploiters prefer to stay with their current model of the world, rather than switch to another. They consider a small part of the hypothesis space, refining the solution that first came to mind. Explorers, in contrast, prefer breadth. They consider a much larger part of the hypothesis space and are therefore less likely to be trapped on a local maximum.

Many animal groups, from honeybees to humans, contain a mixture of exploiters and explorers. A mixture of such diverse individuals can create advantages for the group. Another way in which groups can help individuals overcome individual biases is by changing the incentive structure of the problem at hand, either indirectly e. Groups can overcome some, but not all, of the problems of individual decision-making. We will now consider a number of potential pitfalls facing group decisions, such as lack of independent knowledge, biases that skew the sharing of information or preferences and the problem of competing individual and group goals.

Groupthink is perhaps the most well-known cause of bad group decisions.
