The process of making judgments and decisions requires a method for combining data. To compare the accuracy of clinical and mechanical (formal, statistical) data-combination techniques, we performed a meta-analysis on studies of human health and behavior. On average, mechanical-prediction techniques were about 10% more accurate than clinical predictions. Depending on the specific analysis, mechanical prediction substantially outperformed clinical prediction in 33%-47% of studies examined…

Clinical versus Statistical Prediction
In clinical decision making, clinical (i.e., impressionistic) or statistical (i.e., mechanical) methods may be employed in making specific predictions. Since these methods will not always produce the
Clinical Versus Mechanical Prediction
This chapter compares and contrasts the relative utility of clinical and mechanical methods of prediction. Claims about the robustness of mechanical prediction are countered by recent meta-analyses
In defense of clinical judgment … and mechanical prediction
Despite over 50 years of one-sided research favoring formal prediction rules over human judgment, the “clinical-statistical controversy,” as it has come to be known, remains something of a hot-button
When clinical description becomes statistical prediction.
TLDR
An emerging body of research suggests that clinical observations, just like lay observations, can be quantified using standard psychometric procedures, so that clinical description becomes statistical prediction.
Clinical Judgment and Mechanical Prediction
Computers can be used to make judgments and decisions. In this chapter, the strengths and limitations of mechanical prediction and clinical judgment are described. Judgments made by computers have
Connecting clinical and actuarial prediction with rule-based methods.
TLDR
It is argued that rule-based methods may be more useful than the linear main effect models usually employed in prediction studies, from a data and decision analytic as well as a practical perspective.
A meta-analysis of confidence and judgment accuracy in clinical decision making.
TLDR
The authors synthesized over 40 years of research from 36 studies, from 1970 to 2011, in which the confidence ratings of 1,485 clinicians were assessed in relation to the accuracy of their judgments about mental health or psychological issues, finding that confidence is better calibrated with accuracy than previously assumed.
Methodological advances in statistical prediction.
TLDR
The purpose of this literature review is to describe methodological advances in statistical prediction, including the assignment of weights to predictors, the emergence of new statistical analyses, and the role of theory.
Clinical, Statistical, and Broken-Leg Predictions
Accurate prediction of behavior is a critical task for the psychologist, particularly for the practitioner. Outstanding among those who have successfully wrestled with this complicated task is Paul

Clinical versus Actuarial Prediction
TLDR
In psychology, statistical models are superior even when based on a subset of the information available to clinicians (who might, for example, also interview people) but may even be ‘improper’—as when a linear combination is based on ad hoc (but directionally correct) or intuitive weights.

TLDR
The main conclusions are that linear models are superior to other mathematical models of human judgment, and actuarial methods are more accurate than clinical prediction in many situations and human judgment is flawed.

In coronary artery disease, statistical models developed from carefully collected data can provide prognostic predictions that are more accurate than predictions of experienced clinicians made from detailed case summaries.
