Culture theory is an idea that helps us understand how groups of people think and act. It explains why people from different countries, backgrounds, and beliefs may act differently. It is based on the idea that each society has its own values and beliefs that shape how members of that society think, speak, and act. For example, someone who grew up in India may think and act differently than someone who grew up in France. Culture theory explains why this happens. It helps us see that the way we learn to act is based on the values and beliefs of the culture we grew up in.
