The psychology of social behaviour is based on scientific methods to understand and explain how people think, feel, behave, or get influenced by their surroundings. Therefore, social psychology is all about understanding how the surrounding social environment affects a person's behaviour.n2. Social psychologists are known to focus on societal concerns, which have a decisive influence on individual well-being and the health of society as a whole. These include various social problems such as substance abuse, crime, bullying, prejudice, domestic violence, health, aggression, etc.n3. In simple words, people can dramatically influence how another person acts or their choices. When someone takes any decision or reacts to a particular situation depends on how many and what kind of people are present with them.n4. Social psychology covers many social topics, such as group behaviour, leadership, behaviour (non-verbal), aggression, prejudice, etc.
