Biological Bias

3 March 2018


What does it mean to be a biological being? It means, among other things, that one sees the world from a biological perspective, thinks in terms of concepts amenable to a biological brain, understands oneself and one’s species in its biological context, which is the biosphere of our homeworld, and that one persists in a mode of being distinctive to biological beings (which mode of being we call life). To be a biological being is to be related to the world through one’s biology; one has biological desires, biological aversions, biological imperatives, biological expectations, and biological intentions. Human beings are biological beings, and so are subject to all of these conditions of biological being.

When we think in terms of human bias — and we are subject to many biases as human beings — we usually focus on exclusively human biases, our anthropocentrism, our anthropic bias, but we are also subject to biases that follow from the other ontological classes of beings of which we are members. We are human beings, but we are also cognitive beings (i.e., intelligent agents), linguistic beings, mammalian beings, biological beings, physical beings, Stelliferous Era beings, and so on. This litany may be endless; whether or not we are aware of it, we may belong to an infinitude of ontological classes in virtue of the kind of beings that we are.

Another example of a bias to which human beings are subject but which is not exclusively anthropic, is what I have called terrestrial bias. Some time ago in Terrestrial Bias: Thought Experiments I asked, “…is there, among human beings, any sense of identification with the life of Earth? Is there a terrestrial bias, or will there be a terrestrial bias when we are able to compare our response to terrestrial life to our response to extraterrestrial life?” As I write this it occurs to me that a distinction can be made between planetary bias, to which any being of planetary endemism would be subject, and terrestrial bias understood as a bias specific to Earth, to which only life on Earth would be subject. In making this distinction, we understand that terrestrial bias is a special case of planetary bias, which latter is the more comprehensive concept.

Similarly, anthropic bias is a special case of the more comprehensive concept of intelligent agent bias. Again, we can distinguish between intelligent agent bias and anthropic bias, with intelligent agent bias being the more comprehensive concept under which anthropic bias falls. However, intelligent agents could also include artificial agents, who would be peers of human intelligent agents in respect of intelligence, but which would not share our biological bias. The many biases, then, which attend and inform human cognition, are nested within more comprehensive biases, as well as overlapping with the biases of other agents that might potentially exist and which would share some of our biases but which would not fall under exactly the same more comprehensive concepts. In Wittgensteinian terms, there is a complicated network of biases that overlap and intersect (cf. Philosophical Investigations, sec. 66); these biases correspond to a complicated network of ontological classes that overlap and intersect.

Our biological biases overlap and intersect with our other biases, such as our biases as the result of being human (anthropic bias) or our biases in virtue of being composed of matter (material or physical bias). Biological bias occupies a point midway between these two ontological classes. Our anthropic bias is exclusive to human beings, but we share our biological bias with every living thing on Earth, and perhaps with living things elsewhere in the cosmos, while we share our material bias much more widely with dust and gas and stars, except that these latter beings, not being intelligent agents, cannot exercise judgment or act as agents, so that their bias can only be manifested passively. One might well characterize the Platonic definition of beingthe capacity to affect or be affected — as the passive exercise of bias, with each class of beings affecting and being affected by other beings of the same class as peers.

I have sought to exhibit and disentangle and overlapping and intersecting of biological baises in a number of posts related to biophilia and biophobia, including:

Biocentrism and Biophilia

The Biocentric Thesis

The Scope of Biophilia

Not all biases are catastrophic distortions of reasoning. In Less than Cognitive Bias I made a distinction between anthropic biases that characterize the human condition without necessarily adversely affecting rational judgment, and anthropic biases that do undermine our ability to reason rationally. And in The Human Overview I sketched out the complexity of ordinary human communication, which is dense in subtle biases, some of which compromise our rationality, but many of which are crucial to our ability to rapidly reason about our circumstances — a skill with high survival value, and a skill at which human beings excel and which will not soon by modeled by artificial intelligence on account of its subtlety. A tripartite distinction can be made, then, among biases that compromise our reason, biases that are neutral in regard to out ability to reason, and biases that augment our ability to reason.

Our biological biases coincide to a large extent with our evolutionary psychology, and, in so far as our evolutionary psychology enabled us to survive in our environment of evolutionary adaptedness, our biological biases augment our ability to reason cogently and to act effectively in biological contexts — though only in what might be called peer biological contexts, as far as our particular scale of biological individuality allows us to identify with other biological individuals as peers. Our peer biological biases do not allow us to interact effectively at the level of the microbiome or at the level of the biosphere, with the result that considerable scientific effort has been required for us to understand and to interact effectively at these biological scales.

A similar applicability of bias may be true more widely of our other biases, which help us in some circumstances while hurting us in other circumstances. Certainly our anthropic biases have helped us to survive, and that is why we possess them in such robust forms, though they have helped us to survive as a species of planetary endemism. In the event of humanity breaking out of our homeworld as a spacefaring civilization, our anthropic, homeworld, and planetary endemism biases may not serve us as well in cosmological contexts. however, we know what to do about this. The cultivation of science and rigorous reasoning has allowed us to transcend many of our biases without actually losing our biases. Instead of viewing this as a human, all-too-human failure, we should think of this as a human strength: we can, when we apply ourselves, selectively transcend our biases, but when we need them, they are there for us, and they will be there for us until we actually alter ourselves biologically. Thus there is a biological “way out” from biological biases, but we might want to think twice before pursuing this way out, as our biological biases may well prove to be an asset (and perhaps an asset in unexpected, instinctive ways) when we eventually explore other biospheres and encounter another form of biology.

What Carl Sagan called the “deprovincialization” of biology may also take place at the level of human evolutionary psychology. If so, we shouldn’t desire to transcend or eliminate our biological biases as we should desire to augment and expand them in order to overcome what will be eventually learn about our terrestrial and homeworld biases from the biology of other worlds.

A Conceptual Overview

What is the relationship between planetary endemism and the overview effect? This is the sort of question that might be given a definitive formulation, once once we have gotten sufficiently clear in our understanding of these ideas and their ramifications. I’m not yet at the point of formulating a definitive expression of this relationship, but I’m getting closer to it, so this post will be about formulating relationships among these and related concepts in a way that is hopefully clear and illuminating, while avoiding the ambiguities inherent in novel concepts.

This post is itself a kind of overview, attempting to show in brief compass how a number of interrelated concepts neatly dovetail and provide us with a rough outline of a conceptual overview for understanding the origins, development, distribution, and destiny of civilization (or some other form of emergent complexity) in the universe.


The Stelliferous Era

The Stelliferous Era is that period of cosmological history after the formation of the first stars and before the last stars burn out and leave a cold and dark universe. In the cosmological periodization formulated by Fred Adams and Greg Laughlin, the Stelliferous Era is preceded by the Primordial Era and followed by the Degenerate Era. During the Primordial Era stars have not yet formed, but matter condenses out of the primordial soup; during the Degenerate Era, the degenerate remains of stars, black holes, and some exotic cosmological objects are to the found, but the era of brightly burning stars is over.

What typifies the Stelliferous Era is its many stars, radiating light and heat, and whose nucleosynthesis and supernova explosions forge heavier forms of matter, and therefore the chemical and minerological complexity from which later generations of (high metallicity) stars and planets will form. (A Brief History of the Stelliferous Era is an older post about the Stelliferous Era that needs to be revised and updated.)

In comparison to the later Degenerate Era, Black Hole Era, and Dark Era of cosmological history, the Stelliferous Era is rather brief, extending from 106 to 1014 years from the origins of the universe, and almost everything that concerns us can be further reduced to the eleventh cosmological decade (from 10 billion to 100 billion years since the origin of the universe). Since this cosmological periodization is logarithmic, the later periods are even longer in duration than they initially appear to be.

Our interest in the Stelliferous Era, and, more narrowly, our interest in the eleventh decade of the Stelliferous Era, does not rule out interesting cosmological events in other eras of cosmological history, and it is possible that civilizations and other forms of emergent complexity that appear during the Stelliferous Era may be able to make the transition to survive into the Degenerate Era (cf. Addendum on Degenerate Era Civilization), but this brief period of starlight in cosmological history is the Stelliferous Era window in which it is possible for peer planetary systems, peer species, and peer civilization to exist.

planetary surfaces

Planetary Endemism

Planetary Endemism is the condition of life during the Stelliferous Era as being unique to planetary surfaces and their biospheres. Given the parameters of the Stelliferous Era — a universe with planets, stars, and galaxies, in which both water (cf. The Solar System and Beyond is Awash in Water) and carbon-based organic molecules (cf. Mixed aromatic–aliphatic organic nanoparticles as carriers of unidentified infrared emission features by Sun Kwok and Yong Zhang) are common — planetary surfaces are a “sweet spot” for emergent complexities, as it is on planetary surfaces that energy from stellar insolation can drive chemical processes on mineral- and chemical-rich surfaces. The chemical and geological complexity of the interface between atmosphere, ocean, and land surfaces provide an opportunity for further emergent complexities to arise, and so it is on planetary surfaces that life has its best opportunity during the Stelliferous Era.

Planetary endemism does not rule out exotic forms of life not derived from water and organic macro-molecules, nor does it rule out life arising in locations other than planetary surfaces, but the nature of the Stelliferous Era and the conditions of the universe we observe points to planetary surfaces being the most common locations for life during the Stelliferous Era. Also, the “planetary” in “planetary endemism” should not be construed too narrowly: moons, planetesimals, asteroids, comets and other bodies within a planetary system are also chemically complex loci where stellar insolation can drive further chemical processes, with the possibility of emergent complexities arising in these contexts as well.


The Homeworld Effect

The homeworld effect is the perspective of intelligent agents still subject to planetary endemism. When the emergent complexities fostered by planetary endemism rise to the level of biological complexity necessary to the emergence of consciousness, there are then biological beings with a point of view, i.e., there is something that it is like to be such a biological being (to draw on Nagel’s formulation from “What is it like to be a bat?”). The first being on Earth to open its eyes and look out onto the world possessed the physical and optical perspective dictated by planetary endemism. As biological beings develop in complexity, adding cognitive faculties, and eventually giving rise to further emergent complexities, such as art, technology, and civilization, embedded in these activities and institutions is a perspective rooted in the homeworld effect.

The emergent complexities arising from the action of intelligent agents are, like the biological beings who create them, derived from the biosphere in which the intelligent agent acts. Thus civilization begins as a biocentric institution, embodying the biophilia that is the cognitive expression of biocentrism, which is, in turn, an expression of planetary endemism and the nature of the intelligent agents of planetary endemism being biological beings among other biological beings.

The homeworld effect does not rule out the possibility of exotic forms of life or unusual physical dispositions for life that would not evolve with the homeworld effect as a selection pressure, but given that planetary endemism is the most likely existential condition of biological beings during the Stelliferous Era, it is to be expected that the greater part of biological beings during the Stelliferous Era are products of planetary endemism and so will be subject to the homeworld effect.


The Overview Effect

The overview effect is a consequence of transcending planetary endemism. As biocentric civilizations increase in complexity and sophistication, deriving ever more energy from their homeworld biosphere, biocentric institutions and practices begin to be incrementally replaced by technocentric institutions and practices and civilization starts to approximate a technocentric institution. The turning point in this development is the industrial revolution.

Within two hundred years of the industrial revolution, human beings had set foot on a neighboring body of our planetary system. If a civilization experiences an industrial revolution, it will do so on the basis of already advancing scientific knowledge, and within an historically short period of time that civilization will experience the overview effect. But the unfolding of the overview effect is likely to be a long-term historical process, like the scientific revolution. Transcending planetary endemism means transcending the homeworld effect, but as the homeworld effect has shaped the biology and evolutionary psychology of biological beings subject to planetary endemism, the homeworld effect cannot be transcended as easily as the homeworld itself can be transcended.

For biological beings of planetary endemism, the overview effect occurs only once, though its impact may be gradual and spread out over an extended period of time. An intelligent agent that has evolved on the surface of its homeworld leaves that homeworld only once; every subsequent world studied, explored, or appropriated (or expropriated) by such beings will be first encountered from afar, over astronomical distances, and known to be a planet among planets. A homeworld is transcended only once, and is not initially experienced as a planet among planets, but rather as the ground of all being.

The uniqueness of the overview effect to the homeworld of biological beings of planetary endemism does not rule out further overview effects that could be experienced by a spacefaring civilization, as it eventually is able to see its planetary system, its home galaxy, and its supercluster as isolated wholes. However, following the same line of argument above — stars and their planetary systems being common during the Stelliferous Era, emergent complexities appearing on planetary surfaces characterizing planetary endemism, organisms and minds evolving under the selection pressure of the homeworld effect embodying geocentrism in their sinews and their ideas — it is to be expected that the overview effect of an intelligent agent first understanding, and then actually seeing, its homeworld as a planet among other planets, is the decisive intellectual turning point.


Bifurcation of Planetary and Spacefaring Civilizations

What I have tried to explain here is the tightly-coupled nature of these concepts, each of which implicates the others. Indeed, the four concepts outlined above — the Stelliferous Era, planetary endemism, the homeworld effect, and the overview effect — could be used as the basis of a periodization that should, within certain limits, characterize the emergence of intelligence and civilization in any universe such as ours. Peer civlizations would emerge during the Stelliferous Era subject to planetary endemism, and passing from the homeworld effect to the overview effect.

If such a civilization continues to develop, fully conscious of the overview effect, it would develop as a spacefaring civilization evolving under the (intellectual) selection pressure of the overview effect, and such a civilization would birfurcate significantly from civilizations of planetary endemism still exclusively planetary and still subject to the homeworld effect. These two circumstances represent radically different selection pressures, so that we would expect spacefaring civilizations to rapidly speciate and adaptively radiate once exposed to these novel selection pressures. I have previously called this speciation and adaptive radiation the great voluntaristic divergence.
