Individuals are significantly more likely to help those they perceive as being similar to themselves in terms of appearance, group membership, or shared interests.
This is driven by In-group Favoritism, where we feel a stronger moral obligation toward members of our own social circle or 'tribe'.
Similarity increases empathy; when we see someone like us in trouble, we are more likely to identify with their plight and feel a personal drive to assist.
| Factor | Mechanism | Impact on Helping |
|---|---|---|
| Presence of Others | Diffusion of Responsibility | Decreases as group size increases |
| Similarity | Empathy & In-group Bias | Increases when victim is similar |
| Cost of Helping | Risk Assessment | Decreases if risk/effort is high |
| Cost of Not Helping | Guilt/Social Blame | Increases if the situation is severe |
Identify the Trigger: When a question mentions the number of people present, immediately think of the Bystander Effect and Diffusion of Responsibility.
Distinguish Factors: Ensure you can differentiate between Social Factors (situational/external) and Dispositional Factors (internal/personality).
Explain the 'Why': Don't just state that help decreases in groups; explain that it happens because the perceived responsibility is divided among the crowd.
Check for Ambiguity: If a scenario describes a situation where it is unclear if help is needed, use the term Pluralistic Ignorance to explain why people might look to others before acting.
