Understanding Hypotheses and Theories

Susan Fischer, chair of the Department of Entomology at OSU, discusses the importance of understanding scientific terms like hypothesis and theory. She addresses common misconceptions and emphasizes the need for clarity in scientific discussions, especially on controversial topics like evolution and global warming. Fischer explains that a hypothesis is a testable and falsifiable conjecture, while a theory is a well-substantiated explanation supported by evidence. Understanding these terms is crucial for informed decision-making in scientific issues.
