Varieties of Negligence

Area of Science:

• Psychology
• Moral Psychology
• Legal Psychology

Background:

• Negligence is commonly viewed as a cognitive failure.
• Social judgments of negligence are influenced by the specific mechanisms of failure.
• Existing research lacks a unified framework for understanding these variations.

Purpose of the Study:

• To propose a unified framework for understanding variations in social evaluations of negligence.
• To investigate how different types of negligence (diligence, perceptual/mnemonic errors, ignorance) affect moral judgments.
• To explore the impact of negligence type on blame, perceived intentionality, and legal sanctions.

Main Methods:

• Conducted four pre-registered experiments with 2,727 participants.
• Utilized a judgment-updating paradigm to assess the impact of negligence information.
• Employed self-report measures to gauge attitudes and judgments.
• Investigated priming effects related to ease of avoidance and self-projection.

Main Results:

• Negligence type significantly affected moral judgments, blame, and perceptions of wrongness and accidentality.
• Information about process and diligence differentially influenced these judgments.
• Negligence information reduced perceived intentionality but selectively increased blame for certain negligence types.
• Priming effects demonstrated that emphasizing ease of avoidance increased sanctions, while self-projection cues attenuated them.

Conclusions:

• The study provides a framework integrating diverse negligence research, specifying factors influencing evaluations.
• Findings highlight policy implications for jury instructions and sentencing in negligence cases.
• Acknowledges limitations in generalizability due to a US-based, internet-accessible participant pool.
