Informal theory refers to a set of ideas or concepts that are not formally structured or rigorously defined. Unlike formal theories, which are often developed through systematic research and testing, informal theories are more flexible and can be based on personal experiences, observations, or anecdotal evidence.
These theories are often used in everyday conversations and discussions to explain phenomena or behaviors. They may not have the same level of empirical support as formal theories, but they can still provide valuable insights and help people make sense of the world around them.
For example, an informal theory might suggest that people who are more outgoing tend to be happier. While this idea might not be backed by extensive scientific research, it can still be a useful way to think about the relationship between personality and happiness.
In summary, informal theories are less rigid and more adaptable than formal theories, making them a common tool for understanding and interpreting the world in a more casual, everyday context.
