Book: Range: Why Generalists Triumph in a Specialized World

In his new book, Range: Why Generalists Triumph in a Specialized World, David J. Epstein investigates the significant advantages of generalized cognitive skills for success in a complex world. We’ve heard and read many praises for narrow expertise in both humans and AIs (Watson, Alpha Go, etc.). In both humans and AIs, however, narrow+deep expertise does not translate to adaptiveness when reality presents novel challenges, as it does constantly. 

As you ingest this highly readable, non-technical book, please add your observations to the comments below. 

Homo deus

Power Valued Over Truth

Dear Ed and All,

“We are the ones that create human nature by inculcating cooperation and care over selfishness and power.”

The view you express, Ed, contesting Harari’s claim in Homo deus, seems to edge up closely to the “pre-modern” standard social science of model of human nature, i.e., that it is almost solely a product of culture, with no or minimal influence of naturally selected genes and very fancy naturally selected epigenetic mechanisms for gene regulation. It is the idea that we pretty much are born, mentally, a blank slate. That is demonstrably wrong. There is a deep and mighty pan-cultural, species-typical human nature that impacts all our intrapsychic life and behavior. It is designed only to be impacted in very specific and limited biologically fitness-enhancing ways by local cultural influences. Harari is correct, at least in the sense that our basic nature is only contingently to value truth, that is, only to the extent that it increases our power to generate greater lifetime inclusive fitness.

Yet, and here is where you and I can find, IMO, great and expansive common ground, natural selection in our species created a mind designed to compete in complex multi-partner, multi-currency socioeconomic bargaining, and thus for status (i.e., power), with great acumen, during an ongoing intraspecific arms race with other humans, including close social partners, over the last several hundred thousand years. Importantly, non-trivial metacognition and mentalization (theory of mind) capacities evolved as part of our package of competitive cognitive capacities; these can be used to evaluate, predict, and manipulate others, and to observe and study ourselves. Imaginative capacities and an ability to believe deeply in both fantasy and evidence also evolved to allow us to cohabit “adaptively subjective dreamworlds” (ASD) that hold human groups together. For example, one example of a written down, very dear and pretty darn auspicious ASD is the US Constitution.

Natural selection has zero foresight. This is the only reason we have any chance of beginning to alter how our minds operate. Down the road, once some leaders develop the capacity to make good decisions about how to genetically modify ourselves to be more compassionate and sustainable, probably with the help of evolutionary psychology, a massive program of intentional genetic evolution may be what’s really necessary to get us through our current very dangerous technological adolescence.

Robust, transparent (nonconscious), sly and clever neurological regulatory mechanisms assuredly have evolved to more or less (denoting very slight individual variation in brain development) lock us into making effective and efficient (i.e., powerful) use of our outstanding cognitive abilities to maximize lifetime gene propagation, whether we know this is what we are up to or not.

Yet, this same program of natural selection, epiphenomenally, gave all or most of us the potential — almost always hard won and seldom truly accessed — to employ evolutionarily novel intrapsychic maneuvers, learned from our most sophisticated ancestors, to weaken or “get ahead of” the above-mentioned regulatory mechanisms. Here I am referring to introspective techniques that help us see our own mental operations more objectively, not techniques that just lead to relaxation or greater happiness. This unnaturally objectified seeing can happen in real time (best) or during reflection upon past events (dicey).

An analogy, accidentally constructed by the Wachowskis (?), for using the introspective techniques I’m referring to is vividly given in “The Matrix” trilogy, when Morpheus and his team, eventually especially Neo, purposely send their minds into the matrix via skillful intrapsychic hacking procedures. They are not going in there to sunbathe… even though that would be nice. They cannot. The regulatory mechanisms that already are in place are quite, albeit imperfectly, adaptive in real time. They have the ability to learn. They are seldom are far behind and their prime mandate is to encapsulate or literally destroy the complex neural circuits (i.e, symbolized by Matrix characters like Trinity, Morpheus, Mouse, Sipher) that may collaborate to enable biologically subversive attempts at gaining deep objective self-knowledge. These regulatory mechanisms are key to biologically adaptive neurodevelopment, and they are extraordinarily resourceful and ruthless. They may be limbically based, but any part of the brain can be recruited to help them fulfill their mission, as was “The Matrix” character Sipher.

My own mind largely has been ruined, I feel, by engaging in this process. A lot of my essential “freedom circuitry” has been repeatedly hammered. But, I still believe success is possible for some, particularly if they can learn from the mistakes and rare successes of others. Call it faith in consciousness.

A new analogy has hit me. We are born into a cognitive-emotional prison cell full of delights as well as sources of suffering. (As per astute Buddhist teachings, it’s really all suffering.) But, we may notice that hanging from the ceiling, outside the cell bars but more or less within reach, there are various sets of shiny keys. Usually, one of them opens our cell door. Others keys in the set open additional doors spread throughout an unknown intrapsychic labyrinth. Opening some of those doors triggers an instant alarm, others a delayed alarm, maybe others no alarm at all, especially if the key is inserted and turned correctly. Some sets of keys open doors that lead to traps and cul-de-sacs. You can easily end up in a seemingly nicer jail cell. Or a worse one. Perhaps you can end up in enticing cells, but with no keys hanging outside the bars. It may be hard to tell if one has progressed in any meaningful way.

A legitimate teacher, or cultural tradition, and/or a modern scientific tradition may help us learn something of the labyrinth, and which set of keys to pick that lead to real freedom, or at least time-limited degrees of it. We can learn to go farther and farther.  But the prison is larger and more complex than we typically can conceive, especially anywhere near to our starting position, and especially if we try to do so alone.

Perhaps the best path is right around a nearby intrapsychic corner. But if anyone tells you so, beware. — Paul

Why economics needs a new invisible hand

In this clip Hartmann interviews David Sloan Wilson on his new article by the above name. A new economics needs a new foundation from the typical and shopworn invisible hand proposed by Adam Smith. That new hand is applying evolutionary theory to the topic. David S. Wilson is SUNY Distinguished Professor of Biology and Anthropology at Binghamton University and Arne Næss Chair in Global Justice and the Environment at the University of Oslo. His most recent book is Does Altruism Exist?

Daniel Dennett on the evolution of the mind

The Google talk on his new book, From Bacteria to Bach and Back: The Evolution of Minds. The blurb:

“How did we come to have minds? For centuries, this question has intrigued psychologists, physicists, poets, and philosophers, who have wondered how the human mind developed its unrivaled ability to create, imagine, and explain. Disciples of Darwin have long aspired to explain how consciousness, language, and culture could have appeared through natural selection, blazing promising trails that tend, however, to end in confusion and controversy. Even though our understanding of the inner workings of proteins, neurons, and DNA is deeper than ever before, the matter of how our minds came to be has largely remained a mystery. That is now changing, says Daniel C. Dennett. In From Bacteria to Bach and Back, his most comprehensive exploration of evolutionary thinking yet, he builds on ideas from computer science and biology to show how a comprehending mind could in fact have arisen from a mindless process of natural selection. Part philosophical whodunit, part bold scientific conjecture, this landmark work enlarges themes that have sustained Dennett’s legendary career at the forefront of philosophical thought.”

Meaningful Transhumanism (H+)…

All bodily capacities, including the most impressive, uniquely human cognitive and metacognitive ones, coevolve with regulatory mechanisms. Regulatory mechanisms operate unconsciously, and control the expression of associated capacities such that the latter consistently operate with high effectiveness and efficiency to promote replication of our genes. So, to fundamentally change and render socioecologically sustainable the human species, H+ technologies will somehow have to alter the deep neural relationship between these regulatory “value systems,” (sensu neuroscientist Gerald Edelman in, “A Universe of Consciousness”), residing primarily in the limbic system, and all our mundane or enhanced corticothalamic activities. We need H+ that radically diminishes our transparent penchant for evolutionarily adaptive self-deception, and that alters our power to more freely and consciously choose, moment-to-moment, what we do with our cognitive capacities. I suspect current H+ is blind to this. — Warmly, PJW
