we go about our daily lives, we tend to assume that our perceptions — sights, sounds, textures, tastes — are an accurate portrayal of the real world. Sure, when we stop and think about it — or when we find ourselves fooled by a perceptual illusion — we realize with a jolt that what we perceive is never the world directly, but rather our brain’s best guess at what that world is like, a kind of internal simulation of an external reality. Still, we bank on the fact that our simulation is a reasonably decent one. If it wasn’t, wouldn’t evolution have weeded us out by now? The true reality might be forever beyond our reach, but surely our senses give us at least an inkling of what it’s really like.
Not so, says Donald D. Hoffman, a professor of cognitive science at the University of California, Irvine. Hoffman has spent the past three decades studying perception, artificial intelligence, evolutionary game theory and the brain, and his conclusion is a dramatic one: The world presented to us by our perceptions is nothing like reality. What’s more, he says, we have evolution itself to thank for this magnificent illusion, as it maximizes evolutionary fitness by driving truth to extinction.
Getting at questions about the nature of reality, and disentangling the observer from the observed, is an endeavor that straddles the boundaries of neuroscience and fundamental physics. On one side you’ll find researchers scratching their chins raw trying to understand how a three-pound lump of gray matter obeying nothing more than the ordinary laws of physics can give rise to first-person conscious experience. This is the aptly named “hard problem.”
On the other side are quantum physicists, marveling at the strange fact that quantum systems don’t seem to be definite objects localized in space until we come along to observe them. Experiment after experiment has shown — defying common sense — that if we assume that the particles that make up ordinary objects have an objective, observer-independent existence, we get the wrong answers. The central lesson of quantum physics is clear: There are no public objects sitting out there in some preexisting space. As the physicist John Wheeler put it, “Useful as it is under ordinary circumstances to say that the world exists ‘out there’ independent of us, that view can no longer be upheld.”
So while neuroscientists struggle to understand how there can be such a thing as a first-person reality, quantum physicists have to grapple with the mystery of how there can be anything but a first-person reality. In short, all roads lead back to the observer. And that’s where you can find Hoffman — straddling the boundaries, attempting a mathematical model of the observer, trying to get at the reality behind the illusion. Quanta Magazine caught up with him to find out more.

But how can seeing a false reality be beneficial to an organism’s survival?
There’s a metaphor that’s only been available to us in the past 30 or 40 years, and that’s the desktop interface. Suppose there’s a blue rectangular icon on the lower right corner of your computer’s desktop — does that mean that the file itself is blue and rectangular and lives in the lower right corner of your computer? Of course not. But those are the only things that can be asserted about anything on the desktop — it has color, position and shape. Those are the only categories available to you, and yet none of them are true about the file itself or anything in the computer. They couldn’t possibly be true. That’s an interesting thing. You could not form a true description of the innards of the computer if your entire view of reality was confined to the desktop. And yet the desktop is useful. That blue rectangular icon guides my behavior, and it hides a complex reality that I don’t need to know. That’s the key idea. Evolution has shaped us with perceptions that allow us to survive. They guide adaptive behaviors. But part of that involves hiding from us the stuff we don’t need to know. And that’s pretty much all of reality, whatever reality might be. If you had to spend all that time figuring it out, the tiger would eat you.
I would say that it is hardly a remarkable statement that the brain filters out enormous amounts of data and leaves us with a thin sliver that is more relevant to our survival and possibly to our mental wellbeing too
These evolutionary filters tend to mostly preclude consciousness though and seem pre-conscious to me, already developed by the time we started to develop consciousness. It could be said that it is consciousness that enables to revisit those filters and to tweak/enhance/diminish them if we wish.. a later development.

Ive tried to suggest somewhere in another thread, that this is indeed one of the most remarkable aspects of being human.
Who the fuck actually knows what exists within the energy that we dont see, other than maybe the Shaman and other such brave adventurers?

Fuckin' well said. I was just thinking about possibly the same thing. I used to try and get my dogs and cats to laugh or get a joke. Maybe they did laugh but I was too stupid to notice how they laugh or something. Dogs and cats can make humans laugh, why cannot we do it for them in turn?

And then some show came on and it was about peacocks and he started barking at the screen. Speaking of peacocks the thing that always made me feel sorry for them at the zoo was that they are constantly screaming HELP! They're the most "free" animal in a zoo! They don't got no cages but are free to roam around.
Microbial intelligence (popularly known as bacterial intelligence) is the intelligence shown by microorganisms. The concept encompasses complex adaptive behaviour shown by single cells, and altruistic and/or cooperative behavior in populations of like or unlike cells mediated by chemical signalling that induces physiological or behavioral changes in cells and influences colony structures.
Complex cells, like protozoa or algae, show remarkable abilities to organise themselves in changing circumstances.[1] Shell-building by amoebae reveals complex discrimination and manipulative skills that are ordinarily thought to occur only in multicellular organisms.
Even bacteria, which show primitive behavior as isolated cells, can display more sophisticated behavior as a population. These behaviors occur in single species populations, or mixed species populations. Examples are colonies of myxobacteria, quorum sensing, and biofilms.
It has been suggested that a bacterial colony loosely mimics a biological neural network. The bacteria can take inputs in form of chemical signals, process them and then produce output chemicals to signal other bacteria in the colony.
The mechanisms that enable single celled organisms to coordinate in populations presumably carried over in those lines that evolved multicellularity, and were co-opted as mechanisms to coordinate multicellular organisms.
Bacteria communication and self-organization in the context of network theory has been investigated by Eshel Ben-Jacob research group at Tel Aviv University which developed a fractal model of bacterial colony and identified linguistic and social patterns in colony lifecycle[2] (also see Ben-Jacob's bacteria).

If I may take this further.. I am recalling something I read in M. Scott Peck's 'The Road Less Travelled' where he muses that the larger part of romantic love is very likely a necessary fog on the overactive human mind that enables us to continue as a species.
The reasoning being that, if we were to think too closely (or even at all) about the practicalities and personal commitments of producing and rearing children, we would very likely have far fewer, and so the human species, especially when child/adult mortality was much higher, would very likely have gone extinct.
So there we have the unlikely bedfellows of romantic love and evolutionary biology addressed at the same time, not a bad encapsulation....
