How does reasoning influence intentionality attribution in the case of side effects?

Area of Science:

• Cognitive Psychology
• Moral Psychology
• Social Cognition

Background:

• Objective evaluation of actions requires integrating mental states with consequences.
• Perception of intentionality can be distorted by action consequences.
• The Knobe effect shows greater intentionality attribution for negative than positive side effects.

Purpose of the Study:

• To investigate how reasoning styles and abilities influence judgments of intentionality.
• To understand the mechanisms behind the Knobe effect.
• To explore how cognitive factors affect moral judgments.

Main Methods:

• 172 college students participated in a randomized between-subjects design.
• Participants completed reasoning style questionnaires (REI, AOT) and syllogistic reasoning tasks.
• Scenario-based tasks presented either negative or positive side effects.

Main Results:

• A more deliberative reasoning style reduced bias in intentionality attribution.
• Longer response times were associated with reduced bias.
• Response times mediated the influence of reasoning style on judgment bias.

Conclusions:

• Deliberative reasoning and increased processing time mitigate the Knobe effect.
• Cognitive styles and response latencies play crucial roles in moral judgments.
• Findings suggest pathways to more balanced consideration of actor intent and consequences.
