Most current ethical decision-making models provide a logical and reasoned process for making ethical judgments, but these models are empirically unproven and rely upon assumptions of rational, conscious, and quasilegal reasoning. Such models predominate despite the fact that many nonrational factors influence ethical thought and behavior, including context, perceptions, relationships, emotions, and heuristics. For example, a large body of behavioral research has demonstrated the importance of automatic intuitive and affective processes in decision making and judgment. These processes profoundly affect human behavior and lead to systematic biases and departures from normative theories of rationality. Their influence represents an important but largely unrecognized component of ethical decision making. We selectively review this work; provide various illustrations; and make recommendations for scientists, trainers, and practitioners to aid them in integrating the understanding of nonrational processes with ethical decision making.

Chronic pain is a costly and debilitating condition that has proven difficult to treat, solely with medical interventions, due to the complex interplay of biological, psychological, and social factors in its onset and persistence. Many studies have demonstrated the effectiveness of interdisciplinary treatment that includes psychosocial interventions for low back pain. Nevertheless, these interventions continue to be under-utilized due to concerns of cost and applicability. The present study utilized a cost utility analysis to evaluate effectiveness and associated costs of interdisciplinary early intervention for individuals with acute low back pain that was identified as high-risk for becoming chronic. Treatment effectiveness was evaluated using a standard pain measure and quality-adjusted life years, and associated medical and employment costs were gathered for 1 year. Results indicated that subjects improved significantly from pretreatment to 1-year follow-up, and that the early intervention group reported fewer health-care visits and missed workdays than the treatment as usual group. The majority of 1,000 bootstrapped samples demonstrated the dominance of the early intervention program as being both more effective and less costly from a societal perspective. The early intervention treatment was the preferred option in over 85% of samples within an established range of acceptable costs. These results are encouraging evidence for the cost-effectiveness of interdisciplinary intervention and the benefits of targeted early treatment.

Objective Concerns persist that deep brain stimulation (DBS) for Parkinson’s disease (PD) increases impulsivity and/or induces excessive reward-seeking. We report here the performance of PD patients with implanted subthalamic nucleus electrodes, with stimulation on and off, on three laboratory tasks of risk-taking and decision-making. They are compared to PD patients maintained on medication and normal control subjects. Methods and Results In the Game of Dice Task, a test of “risky” decision-making, PD patients with or without DBS made highest-risk bets more often, and ended up with less money, than normal controls. There was a trend for DBS stimulation to ameliorate this effect. Deal or No-Deal is an “ambiguous” decision-making task that assessed preference for risk (holding on to one’s briefcase) over a “sure thing” (accepting the banker’s offer). Here, DBS patients were more conservative with stimulation on than off. They accepted smaller offers from the banker and won less money in the DBS-on condition. Overall, the two PD groups won less money than healthy participants. The Framing Paradigm assessed willingness to gamble on a fixed (unambiguous) prize depending on whether the reward was “framed” as a loss or a gain. Nonsurgical PD patients tended to be more risk-averse than normal subjects, whereas DBS patients were more willing to gamble for gains as well as losses both on and off stimulation. Conclusions On “risky” decision-making tasks, DBS patients were more risk-taking than normal, but stimulation may temper this tendency. In contrast, in an “ambiguous risk” situation, DBS patients were more risk-averse (conservative) than normal, and this tendency was greatest with stimulation.

History of major dementia risk factors can be ascertained through the Internet, and several of these factors are shown to be moderately predictive of performance on a brief test of episodic memory. These data provide preliminary validation of the Dementia Risk Assessment for identifying current cognitive impairment, and suggest its potential for assessing future dementia risk. Ongoing studies will further establish the validity of these findings against proxy reports of cognitive and functional decline, the results of more detailed cognitive assessments, and formal clinical diagnoses.
