The main difference between fact and opinion lies in their foundational characteristics. A fact is a statement that can be proven true or false through evidence, observation, or reliable sources. For example, "Water boils at 100 degrees Celsius at sea level" is a fact that can be verified through scientific measurement. In contrast, an opinion reflects a personal belief, judgment, or perspective that is subjective and not universally verifiable. For instance, saying "Chocolate is the best ice cream flavor" is an opinion because it is based on individual tastes and cannot be proven true in the same way that a fact can.

This distinction is crucial for understanding how information is presented and evaluated, particularly in academic and critical thinking contexts. Recognizing the difference allows individuals to better assess the reliability and validity of the information they encounter.
