People judge harmful side effects as more intentional than helpful ones, a phenomenon called the side-effect effect (SEE). This study found anger does not explain the SEE, suggesting blame motivation is key.
Area of Science:
- Cognitive Psychology
- Moral Psychology
- Social Psychology
Background:
- The side-effect effect (SEE) describes the tendency to perceive harmful side effects as more intentional than beneficial ones.
- This asymmetry in judgment highlights the influence of moral considerations on non-moral concepts like intentionality.
- The psychological mechanisms underlying the SEE, particularly the role of affect, remain debated.
Purpose of the Study:
- To investigate the affective bias hypothesis (ABH), which posits that anger towards agents causing harm drives the SEE.
- To systematically examine the role of anger in intentionality judgments within the context of the SEE.
- To explore alternative explanations for the SEE beyond affective responses.
Main Methods:
- A series of empirical studies were conducted.
- Participants' anger levels were systematically measured and manipulated.
- Intentionality judgments in scenarios involving harmful and helpful side effects were analyzed.
Main Results:
- Findings indicate that anger does not play a significant role in intentionality judgments related to the SEE.
- The study provides evidence against the affective bias hypothesis as the primary explanation for the SEE.
- Results support the role of non-emotional motivation to blame in driving the SEE.
Conclusions:
- Anger is not the driving force behind the side-effect effect.
- The SEE appears to be influenced by a motivation to blame, independent of emotional responses like anger.
- Further research should explore non-affective factors contributing to moral judgments of intentionality.
