Anchoring and publicity effects in clinical judgment.

Area of Science:

• Psychology
• Clinical Psychology
• Cognitive Bias

Background:

• Social-cognitive bias literature suggests clinicians may be susceptible to anchoring and publicity effects.
• These biases can influence diagnostic judgments and treatment planning.

Purpose of the Study:

• To investigate anchoring and publicity effects in experienced clinicians' successive judgments of client interview notes.
• To determine if the timing of salient case material influences clinicians' estimates of pathology and prognosis.

Main Methods:

• Forty-six clinicians made successive judgments of detailed interview notes (five per case).
• Anchoring was assessed by relating final judgment estimates to the timing of salient, pathognomonic case material.
• Publicity effect was examined by comparing ratings from clinicians who provided written justifications versus those who did not.

Main Results:

• Significant anchoring was observed in one of the two cases, suggesting a bias to disregard pathognomonic data when a client is initially perceived as less disturbed.
• The publicity effect was not found; public justification did not correlate with ratings, confidence, or differ by case.
• Clinicians' experience level did not mitigate the observed anchoring effect.

Conclusions:

• Clinicians may exhibit anchoring bias, potentially overlooking critical information based on initial impressions.
• The tested publicity effect did not significantly alter clinicians' judgment conservatism or confidence.
• Further research is needed to explore the nuances of cognitive biases in clinical decision-making and potential interventions.
