Donald Hoffman explains it very well in his book The Case Against Reality. Here's the short version of the Fitness Beats Truth theorem:
If our ancestors had evolved to see truth, then they'd have all died before passing on their genes, because they would have been outcompeted by the organisms which perceive fitness. Perceiving truth is a waste of energy and resources. Creatures that perceive fitness will always adapt better to the environment with fewer resources.
I can't say I've heard of that book. I'll have to look into it.
About your theorem:
Tbh, I just kinda see it as an affirmation of the kind of materialism Marxism is talking about. There no eternal "Truth" to be perceived, it's all relative. In the context of natural selection, maybe truth is the best strategy to survive. When organism are struggling for the best fitness they are entering into a complex web of material relationships with their environment. This process of natural selection has been going on for far longer than humans have been able to conceive of it. Marxism is just the theory of evolution by natural selection but for the development of human society. Unless I missed the point of your theorem...
I think you missed at least some of the point. Note that the theory of evolution holds true within any system of competing agents capable of hereditary changes. Even for memes, which can only exist in the minds of intelligent species. The theory of evolution holds true even in situations where the environment in which human beings truly exist is not a world. There must be an environment of some kind, yes, but that environment does not require matter, energy, spacetime, or any number of other symbols from our interface to exist. The FBT theorem does not depend upon there being a world in order to hold true. Rather, it erodes the concept of there being a world such as humans would understand it to be a world, because it confirms that our perceptions of the world are perceptions of fitness, not truth. Our reality is simply a tool to help us survive and reproduce. It is not passed down from God to show us truth.
We can fundamentally alter our perceptions. That's what the entire field of chaos magic is for. And chaos magic is essential to trans liberation, pagan coexistence, and, in my opinion, the revolution itself.
Archimedes said, "Give me a lever long enough and a fulcrum on which to balance it, and I shall move the world." Chaos magicians take a similar view when it comes to moving the mind. Tools of magic are levers, and your learned ability to control your own beliefs is the fulcrum. Any mental change is possible if these two tools are advanced enough.
I seek to use chaos magic to effect societal change that will further the goals of the revolution.
Our perception of reality isn't consistent, though. Our perceptions can be changed quite easily. Optical illusions can show us things that aren't there, schizophrenia can convince us of things that aren't true, and religion and magick can change how we interpret what we see into a worldview. And actually, these facts are deeply relevant to surviving as a species and not killing each other --
When a transphobe looks at a trans woman, they see a man. When an ally looks at a trans woman, they see a woman. Perceiving a trans woman to be a man is a form of life threatening violence. It is our ethical duty to perceive trans people as they wish to be perceived, both as workers maintaining class solidarity and as fundamentally decent people. Trans liberation requires that we see our perceptions as malleable, and within our control. To pass the buck onto an imagined "material reality" and demand reality control our perceptions for us is irresponsible, transphobic, and violent.
Demanding that trans people undergo visible transition and changes in gender presentation before we will perceive them as they wish is violent. Just change your thoughts, don't put the burden on the person who may die if their efforts to transition fail.
The difference between perception and truth is not a criticism of the materialist perspective and would arguably align with it better than the alternative.
Though I'd say that anyone making sweeping generalizations about evolutionary fitness either doesn't understand it or is oversimplifying for effect.
I've taken several undergraduate courses in evolutionary biology and done a 4th year research course. I really struggle to understand what is being said.
I often try to take what others say prima facie and interpret it my own way, that is in a scientific and materialist way.
Perhaps one interpretation could be the sum total information available to our sensory organs needs to be filtered through heuristics to determine what is useful in order to contend with immediate needs so as to survive and reproduce. Any deviation from the 'analog' world or of whatever external material world there is and our own reductionist understanding hides the truth from us. Therefore the claim is the ownership of an epistemic advantage or insight unavailable to most others. This treads on relativism and solipsism, since if this is true, it does not do very much to help the rest of us.
I don't know, I tried to engage respectfully but I'm still drawing blanks.
I think the academic in question is making a very simple claim while using obscuring language and methodologies.
It's literally just that perception can do a good, and even better job of increasing fitness by latching on to not-exactly-true things, and in fact does not necessarily ever need to actually identify true things. Just true-ish things such that there can be useful response to the environment.
Kind of like how we see faces where they don't exist. Our brains have evolved to recognize certain patterns as faces, which is surely very useful for fitness in various contexts (recognizing another human). But the perception is buggy, it's fuzzy, it makes a pretty good number of false positives. Did we evolve to see the "truth" of existing faces, or just an approximation?
Anyways the topic is cool but I'm convinced OP doesn't understand it.
There is no evolutionary niche better served by perceiving truth than fitness, except perhaps for the niche that humanity has created for itself by inventing technology that is capable of destroying the Earth's habitability to human life. And a situation like that has never existed on earth before now, so there is no way any organism can have adapted to it.
It's very unclear what you're trying to say because you're using terms with common definitions in evolutionary biology but in ways that make no sense, but also difficult to understand as profound or meaningful if I try to understand them with other definitions.
For example, fitness isn't an evolutionary niche at all. In evolution, niches are relevant to fitness, as they are patterns of (often mutually-excluding) ecological roles played by different organisms over time and space, suggesting some common constraints and situations in the overall fitness landscape. But fitness is not itself a niche. I have no idea what you mean by niche otherwise, but it doesn't make in the context of the field you're wading into.
Anyways I'll try to explain this more by addressing the rest.
This is also not a niche. No other organism, to our knowledge, has such a role or can have it ecologically framed. It's like saying Elon Musk is the best person on the "South African failson that owns SpaceX" team. It's just the one guy, there's no team.
So what? There's no clear point here.
It really feels like you've read some pop science and maybe didn't really understand it. Do you think that's possible?
