Heuristics and Biases: The Psychology of Intuitive Judgment

Much research in the last two decades has demon- strated that human responses deviate from the performance deemed normative according to various models of decision mak- ing and rational judgment (e.g., the basic axioms of utility theory). This gap between the normative and the descriptive can be inter- preted as indicating systematic irrationalities in human cognition. However, four alternative interpretations preserve the assumption that human behavior and cognition is largely rational. These posit that the gap is due to (1) performance errors, (2) computational limitations, (3) the wrong norm being applied by the experi- menter, and (4) a different construal of the task by the subject. In the debates about the viability of these alternative explanations, attention has been focused too narrowly on the modal response. In a series of experiments involving most of the classic tasks in the heuristics and biases literature, we have examined the implica- tions of individual differences in performance for each of the four explanations of the normative/descriptive gap. Performance er- rors are a minor factor in the gap; computational limitations un- derlie non-normative responding on several tasks, particularly those that involve some type of cognitive decontextualization. Un- expected patterns of covariance can suggest when the wrong norm is being applied to a task or when an alternative construal of the task should be considered appropriate.

Individual differences in reasoning: Implications for the rationality debate?

In this review, we examine the oft-made claim that peer-relationship difficulties in childhood predict serious adjustment problems in later life. The article begins with a framework for conceptualizing and assessing children's peer difficulties and with a discussion of conceptual and methodological issues in longitudinal risk research. Following this, three indexes of problematic peer relationships (acceptance, aggressiveness, and shyness/withdrawal) are evaluated as predictors of three later outcomes (dropping out of school, criminality, and psychcpathology). The relation between peer difficulties and later maladjustment is examined in terms of both the consistency and strength of prediction. A review and analysis of the literature indicates general support for the hypothesis that children with poor peer adjustment are at risk for later life difficulties. Support is clearest for the outcomes of dropping out and criminality. It is also clearest for low acceptance and aggressiveness as predictors, whereas a link between shyness/withdrawal and later maladjustment has not yet been adequately tested. The article concludes with a critical discussion of the implicit models that have guided past research in this area and a set of recommendations for the next generation of research on the risk

Peer relations and later personal adjustment: Are low-accepted children at risk?

Modern theories in cognitive psychology and neuroscience indicate that there are two fundamental ways in which human beings comprehend risk. The analytic system uses algorithms and normative rules, such as probability calculus, formal logic, and risk assessment. It is relatively slow, effortful, and requires conscious control. The experiential system is intuitive, fast, mostly automatic, and not very accessible to conscious awareness. The experiential system enabled human beings to survive during their long period of evolution and remains today the most natural and most common way to respond to risk. It relies on images and associations, linked by experience to emotion and affect (a feeling that something is good or bad). This system represents risk as a feeling that tells us whether it's safe to walk down this dark street or drink this strange-smelling water. Proponents of formal risk analysis tend to view affective responses to risk as irrational. Current wisdom disputes this view. The rational and the experiential systems operate in parallel and each seems to depend on the other for guidance. Studies have demonstrated that analytic reasoning cannot be effective unless it is guided by emotion and affect. Rational decision making requires proper integration of both modes of thought. Both systems have their advantages, biases, and limitations. Now that we are beginning to understand the complex interplay between emotion and reason that is essential to rational behavior, the challenge before us is to think creatively about what this means for managing risk. On the one hand, how do we apply reason to temper the strong emotions engendered by some risk events? On the other hand, how do we infuse needed "doses of feeling" into circumstances where lack of experience may otherwise leave us too "coldly rational"? This article addresses these important questions.

Risk As Analysis and Risk As Feelings: Some Thoughts About Affect, Reason, Risk, and Rationality

The case for prediction the Modified Desert Model of criminal sentencing.

Treating people with mental disorder without their consent always has been the defining human rights issue in mental health law. For centuries, unwanted treatment took place in a closed institution, a mental hospital. What has changed is that in recent years the locus of involuntary treatment has

Mandated Community Treatment: Applying Leverage to Achieve Adherence

Dix (1976) recently has proposed that a “true experiment” be conducted to assess the validity of predictions of imminent violence. A random sample of persons predicted to be iminently violent would be denied emergency civil commitment in order to test whether they do, in fact, commit a violent act. This article analyzes Dix's proposal and finds that it presents an unacceptable level of risk to the community. Four alternative methodologies by which preliminary data can be gathered on the validity of predictions of violence in emergency civil commitment are described.

Strategies for an empirical analysis of the prediction of violence in emergency civil commitment

Objective: This study tested the hypothesis that contraction of regional economies affects the incidence of involuntary admissions to psychiatric emergency services by reducing community tolerance for persons perceived as threatening to others. Methods: This hypothesis was tested with time-series analyses of the relationship between initial claims for unemployment in Florida between July 4, 1999, and June 28, 2003, and the weekly number of men and women presented by police to be examined for involuntary psychiatric hospitalization because of danger to others. The analyses controlled for admissions presented by mental health professionals because of danger to others and for admissions presented by police because of neglect or disability. Results: When the analyses controlled for autocorrelation and other covariates, claims for unemployment insurance were significantly associated with the number of men presented by police for danger to others. During the study period, police presented 5,897 men for examination because of danger to others. Increased unemployment claims were associated with approximately 309 more men being presented for examination than expected from prior presentation rates and from the number presented by mental health professionals for danger to others and by police for neglect or disability. No such association was found for women. Conclusions: Consistent with theory, this study found that presentations for involuntary admission to psychiatric services increased after contractions in the labor market. Combining the methods of this study with econometric forecasting may allow providers to anticipate better the need for psychiatric services. (Psychiatric Services 57:1435–1439, 2006)
