states and people who have similar life experiences are more likely sympathy. People in spatial or geographic proximity (such as neighbors and citizens of a given country) are more likely to experience sympathy towards each other. Social proximity follows the same pattern: Members of certain groups (e.g. racial groups) are more sympathetic to people who are also members of the group. Social proximity is linked with in-group/out-group status. People within the same group are interconnected and share successes and failures and therefore experience more sympathy towards each other than to out-group members, or social outsiders. New and emotionally provoking situations also heighten empathic emotions, such as sympathy. People seem to habituate to events that are similar in content and type and strength of emotion. The first horrific event that is witnessed will elicit a greater sympathetic response compared to the subsequent experiences of the same horrific event. Evolutionary origins The evolution of sympathy is tied to the development of social intelligence: a broad range of behaviors and their associated cognitive skills, such as pair bonding, the creation of social hierarchies, and alliance formation. Researchers theorize that empathic emotions, or those relating to the emotions of others, arose due to reciprocal altruism, mother-child bonding, and the need to accurately estimate the future actions of conspecifics. Empathic emotions emerged from the need to create relationships that were mutually beneficial and to better understand the emotions of others that could avert danger or stimulate positive outcomes. Small groups of socially dependent individuals may develop empathic concerns, and later sympathy, if certain prerequisites are met. The individuals in this community must have a long enough lifespan to encounter several opportunities to react with sympathy. Parental care relationships, alliances during conflicts, and the creation of social hierarchies are associated with the onset of sympathy in human interactions. Sympathetic behavior originally came about during dangerous situations, such as predator sightings, and moments when aid was needed for the sick and/or wounded. The evolution of sympathy as a social catalyst can be seen in both primate species and in human development. Communication Verbal communication is one way individuals communicate feelings of sympathy. People can express sympathy by addressing the emotions being felt by themselves and others involved and by acknowledging the current environmental conditions for why sympathy is the appropriate reaction. Nonverbal communication includes speech intonation, facial expression, body motions, person-to-person physical contact, how far people position
