This is a two pronged issue: no actual scientist would publish Forrester work in a peer reviewed journal, what with them being mad and all. It would be akin to someone publishing that vaccines cause climate change. No one reputable would do it, because it literally wouldn’t be good science. And since it’s, presumably, a serious mad experiment, if the the Forresters wanted to put out their findings, they’d want it taken seriously.
The other element is, would they WANT to publish at all? Like, if you’re a mad scientist experimenting with creating a death ray, you’re doing that for yourself. You don’t want just any mook death-rayin’ all over the place. At best, they might be sharing their findings in Popular Mad Science, assuming they wanted to spread the word, but the return on investment for publishing to the normal science world would be low.
Though there’s also a monkeywrench third element: has any Forrester COMPLETED the research? Clay had to deal with losing two research assistant second bananas, one research subject, having to take care of his mother, and then becoming a baby. Pearl only had about 3 years to continue research before once again losing a test subject, and part of that time was spent chasing him down, being trapped in Ancient Rome, etc. And with research long dormant when Kinga picked up (to say nothing of the many setbacks she herself has had), it seems logical that she probably needed to largely start from the beginning even if she was working off Clay and Pearl’s notes.
I would’ve assumed that mad science in general has a pretty closed off community of peers. Y’know, so no regular scientists accidentally get mixed in. I imagine that makes it a little tough for folks with specialized fields — y’know, the mad ornithologist doesn’t necessarily want their work reviewed by a mad astrophysicist. And the Forresters…well, I’m not sure what field they’re in. But maybe they haven’t published because there isn’t anyone to review their findings.
…Whatever those might be…
