No self-respecting field of science would need a bunch of amateurs......
All of your historical or more precisely "quasi historical" examples have substantial and quite well known counter examples and/or convincing rejoinders. The notion of "self respect" here, even if a "figure of speech" is definitive in its error-- that is, it is completely wrong:
You cannot be referring to the LENR researcher community itself. Many of the often courageous leading LENR researchers must surely have immense SELF respect. And in fact it appears that many, if not all, LENR researchers are capable of conducting falsifiable hypothesis testing.
The science, or if you wish "science", of LENR (and related other CF acronyms) clearly also has SELF respect, that is it has its own literature, it has experts and "peers", it has international meetings, it has developed a substantial body of peer-reviewed research, and in spite of sustained efforts against it, and the continuing efforts in popular media against it, it refuses to die.
LENR is strongly driven by empirical evidence. A necessary (that is a sine qua non) for science and scientific inquiry. Unifying principles are still awaiting more widespread understanding (among scientists and lay public) of the complexities of condensed matter theory, molecular physics and even catalysis.
