The cold fusion people were actively touting data that didn't align to known fusion reactions. Like there are a limited number of elements one can fuse, but for some reason their reaction (which is known) had the energy off by like 300-400 KeV. For example: a proton signal of 2.6 MeV instead of the known 3MeV signal.
