Final answer:
Replication is a true method used by ESP researchers to determine the reliability of psi phenomena, aiming to ensure that results are not due to chance, and are consistent to achieve scientific consensus.
Step-by-step explanation:
Replication is indeed a research method that ESP (extrasensory perception) researchers use to determine the reliability of psi phenomena. The statement that replication is a method to ascertain the reliability of psi phenomena is true. Replicability is critical in the scientific method as it enhances credibility and ensures that the findings are not due to chance or other variables.
Replication involves other researchers conducting the study again using the same methodology to see if they can get similar results. This is important because it helps establish consistency across different studies, which is pivotal in achieving scientific consensus.
Moreover, scientific knowledge is considered an iterative process, and scientists must communicate their findings through published scientific articles. The use of statistical measurements like the P-value also plays an instrumental role in determining significance in scientific research. By ensuring that results can be replicated across various studies, science moves forward with more confidence in the established knowledge.
