Human beings have a strong, natural need to belong. We all want relationships, friendship, love, and support. In their research C. Nathan DeWall, Brad J. Bushman said that feeling accepted by others gives us a sense of safety, connection, and self‑worth, while being rejected or ignored can feel deeply painful. This need is so powerful because, throughout history, people depended on groups for protection, food, and survival, so our minds developed a strong motivation to create and maintain social bonds. Social acceptance means feeling welcomed and included by others, and it can happen in many situations in life. When we feel that we belong and that people value us, our mood improves and we feel more emotionally secure; it also increases our confidence and makes it easier to express ourselves and interact with others. Social rejection occurs when a person feels unwanted or unvalued, and it can take many forms, such as being ignored, excluded, or left out of activities; sometimes rejection is very direct, and at other times it is less obvious.
Rejection can hurt more than we might expect because social connection is very important for human beings, and when someone experiences rejection they often feel sad, hurt, anxious, and disappointed. Rejection also affects the way we think: after being rejected, people become more sensitive to social information and pay extra attention to how others behave, what messages they send, and how they respond, so they may start looking for signs that others do not like them, and small changes in someone’s behavior can feel more important than they actually are. Rejection affects behavior differently in different people: some withdraw, some stop talking, and some avoid social situations, while others may respond with anger or aggression, and some people try very hard to regain acceptance and may constantly seek reassurance, so the same experience of rejection can lead to different behaviors.
Research also shows that the brain areas involved in the unpleasant part of physical pain are also active during social rejection; this does not mean emotional pain and physical injury are exactly the same, but their brain systems overlap, which is why people say things like “my heart hurts” or “I feel broken,” and emotional pain should not be dismissed as someone being too sensitive. Rejection can become a vicious cycle where negative thoughts lead to emotional pain, which leads to withdrawal or anger, which in turn makes relationships more difficult and makes the person more likely to perceive further rejection. Positive memories can help people who experience rejection; by remembering supportive and positive relationships and telling themselves, “I have been accepted by others” or “One person’s behavior does not decide my worth,” they can reduce the tendency to see the entire social world as rejecting.
