Discuss how the critical thinking principles of falsifiability and replicability

•   Falsifiability: Research theory can be shown to be incorrect (as well as correct). The student needs to explain why this is often/sometimes lacking with ESP claims. Also, a student should describe why a theory that is not falsifiable is meaningless in the realm of science.
•   Replicability: Research results need to be verified or repeated by others. In science, it is paramount that other investigators using the same procedures but working in different places with different participants can repeat the same pattern of findings as the original researchers. The student needs to explain what this means more generally in the realm of ESP claims.
