How the former President of MIT, Charles Vest, refused to order an investigation into how the Plasma Fusion Center handled the replication, and their obviously unscientific behavior -- such as partying for the death of something instead of doing unbiased research. Even worse, years later he signed onto a Department of Energy report stating that cold fusion did not deserve funding for research, yet hot fusion deserved millions of additional dollars and was a "bargain."
Conflicts of interest were ignored from the very start. For example, those who had the strongest need for cold fusion to be proven not to work (hot fusion scientists), were tasked with the replication of the effect. It would be like giving a cigarette company the order to conduct a study on the reality of lung cancer, or the lumber industry the job of determining the usefulness of industrial hemp. What the hot fusion scientists were going to say was obvious!
How some scientists were so closed minded they stated that if cold fusion was real, Pons and Fleischmann should be dead from radiation poisoning. In addition, some scientists went so far as to personally attack them. In one case, a scientist stated that even if a thousand tests showed excess heat, that the results would not vindicate Pons and Fleischmann.
