Possibly. I admit I'm mostly going on how I've seen you use the phrase, which has seemed to be in similar circumstances. It also seems broadly in line with how Pauli coined it:

"However, this was not his most severe criticism, which he reserved for theories or theses so unclearly presented as to be untestable or unevaluatable and, thus, not properly belonging within the realm of science, even though posing as such. They were worse than wrong because they could not be proven wrong. Famously, he once said of such an unclear paper: Das ist nicht nur nicht richtig, es ist nicht einmal falsch! 'Not only is it not right, it's not even wrong!'"

I don't say that about the whole of cryonics. I do say that about much of the 'scientific' evidence presented to support the more speculative bits.
