For instance, due to the fact that Fleishmann and Pons withheld the complete experimental design, many scientists attempted the experiment and failed. Much time and money was expended from these failed replications. Fleishmann and Pons gave others false hope in replicating the creation of cold fusion. They also, inadvertently, destroyed their careers in the process. Because their experiment was not reliable and valid, physicists lost respect for its findings.
Reliability ensures that the experiment can be successfully replicated.
Pseudoscience lacks each of these fundamental concepts. Not only did Pons and Fleishmann fail to create a nuclear reaction, their experiment could not be replicated. Had they truly developed cold fusion they would not be with us today continuing their research. The lack of validity and reliability is the benchmark of Pseudoscience.
