Quizplus · Accepted Answer

Theories are derived through scientific research and must be testable and verifiable through the use of research procedures. Mere opinions or beliefs do not have the same level of empirical support. Additionally, a theory may be influenced by cultural values, but this is not a defining characteristic of what makes it a theory. A theory also does not have to be able to explain all aspects of development in order to be valid.
