Have you read the full 2004 Ennis paper?
That's an extremely good question, and I hope meow will answer it.
I've read it. Insofar as I could. It is without exception the most obfuscatory, incomprehensible, opaque, convoluted piece of user-hostile writing it has ever been my misfortune to encounter, and I've seen a lot I can tell you (I scrutinise papers for scientific jouirnals quite regularly). I even include Milgrom's quantum flapdoodle papers here, and that's saying a lot.
It is, quite frankly, almost impossible to understand. I have to wonder what the scrutineers were thinking of, but honestly, sometimes people get intimidated by very very obscure presentations and instead of saying, here, send this back to the authors and tell them to re-write it so it can be understood, they just pass it rather than admit they don't really follow it.
I can only speculate why anyone would write that way, especially if they've got results which challenge the very fundamentals of our world-view. Possibly because the "significant" findings took a lot of teasing out of the raw data? Possibly in order to make it difficult to criticise?
The comparison with Pons and Fleischmann is appropriate, however there is one difference. The physics/chemistry establishment bought into Pons and Fleischmann at first. They were sceptical, yes, because the theory sounded dodgy from the get-go, but there was enough there that researchers felt it was worth their while to get involved in testing the claims. Partly because of natural scientific curiosity, and partly of course because there would have been great prestige in being the guy who managed to replicate the alleged findings.
The Benveniste/Ennis claims are similar. They suggest that much of what we think is true about the basic functioning of matter is flawed. Normally, this sort of claim has physicists and chemists swarming all over it, all wanting to be the first to solve the mystery. However, that ain't happening. Why not? Because, frankly, any serious physicist or chemist can see there's nothing there but a noisy, unstable system that sometimes seems to generate "significant" output - exactly what Pons and Fleischmann had, come to think of it.
And as for Madeleine Ennis being a non-believer. Well, that's her account of how she came to the subject originally. She's been a complete woo for quite a number of years now. The gullible and those prone to delusion can be encountered in all walks of life, even, though it pains me to say it, amoung biochemists.
