In a world increasingly saturated with artificial intelligence, the perceived value of a human mind isn’t what it used to be. As information accelerates and leverage shifts, the most important question becomes not how smart you are, but how effectively your mind is deployed. This five-part series explores a layered, systems-oriented mental model for cognitive effectiveness. It moves up from the biological to the strategic in an attempt to offer a blueprint for staying relevant in the era of ubiquitous intelligence.
Traditionally speaking, God has given me many gifts. There is one gift, more than any other, that’s anchored how I understand myself, my relationship with the world around me, and how I’ve made myself understood by the others in it. For better and worse, that is the gift of my mind.
Yes, I am more than a mind. However, I just can’t ignore the absolutely central role that mine has played in shaping my identity and competitive advantages. As a child, it forged the sole persona I could leverage to earn attention and validation outside the family unit. As a young adult, it was the ladder I used to climb up from the inevitable pit of silent mediocrity, perhaps even American poverty, to a place where I could flirt with upward mobility. As an academic, a technologist, and a professional, it has been the sharpest implement in my cache, the one I instinctively reach for to drive precisely into the sheer face of modern work and ambition. More meaningfully, it has also been the governing frequency of my deepest and longest-lasting friendships in adulthood.
It’s shaped how I work, how I connect, and how I navigate the hidden rules of virtually every situation I find myself in. I shudder at the possibility of experiencing the universe through a narrower aperture.
And yet, despite all of this, I carry the nagging (read: obvious) sense that I’ve yet to live up to the full potential inherent to this gift. And worse, at least without intentional action, I fear it’s decreasing in its relevance – both with and without an A.I. future. These worrisome feelings are at the heart of my exploration in this blog chain.
How to Not Waste a Mind?
There are also deeper questions in play:
Is there a practical ceiling to the potential of a mind or its utility? How can I reconcile what I observe in others—executives, strategists, capital allocators—who are operating at levels beyond my effect but not beyond my comprehension? And in a world increasingly shaped by the algorithmic leverage of artificial intelligence, can I continue to anchor not only my value, but also my identity, to the effectiveness of my mind?
If I truly believe that my mind is not only the essential component of how I navigate the world but also my primary form of leverage, then it’s unwise to rely on it implicitly. I have a need and a responsibility to understand it systematically. More than simply self-awareness, it’s a matter of staying relevant. This need for continued relevance is acutely present in the workplace and broader economy where I compete with other humans. And soon, that competitive landscape will morph as those same humans augment themselves with systems that mimic expertise, don’t sleep, don’t hesitate, and don’t spend time in self-reflection.
When I boil all of this down to its most simple terms, I think the question then becomes:
“How do I not waste my mind?”
Changing Frames: Cognitive Effectiveness
I believe the best way to address this question is by first reframing our performance metric of the mind from “intelligence” to “cognitive effectiveness”. This shift in language represents a shift from input or potential to output and outcome. And in embracing this idea myself, I have developed and refined a mental model for cognitive effectiveness over the years that I believe to be (mostly) correct. I have leveraged it explicitly for about a half-decade, implicitly perhaps longer. In full transparency, I haven’t done the research to see if this model, or something similar, already exists somewhere (I suspect it does) or if it’s described with different language (it probably is). But I would retort with my perpetual disclaimer that this is a personal blog and not a dissertation.
In short, I see cognitive effectiveness as an end-to-end measure of how much a mind can be leveraged to achieve a valued outcome. While I believe that we colloquially refer to cognitive effectiveness as intelligence, I also hold that a correct model of cognitive effectiveness subsumes the concept of intelligence. Put another way, I believe that cognitive effectiveness is the manifestation of the potential of our minds within the reality of our existence. In both expressions, there’s a nuanced debate of absolute or relative measure to be had – I will address that in a later post in this chain.
The genesis of this model came to me while reading a science fiction novel. To some, that may seem like an odd resource for understanding cognitive effectiveness. But to me, this is perfectly natural. I was a child of science fiction. It’s a genre that has always spoken to me more clearly and inspirationally than any other. I think it’s because it surfaces part of our inheritance: to first speculate about our future and then go and build it. The “fiction” part has never bothered me. As far as I am concerned, the possibilities cast into reality from the words on the page to the images in my mind are every bit as real as any other possible future. Where captured intelligently or insightfully, they scream to me of inevitability.
Consider Phlebas
Years ago, I read and thoroughly enjoyed the sci-fi novel, Consider Phlebas by Ian M. Banks. In it, Banks describes a universe where two advanced civilizations are in the midst of a brutal war. One of these advanced civilizations, The Culture , is a post-scarcity, A.I.-governed, anarchist utopia made up of humanoids and super intelligent machines called Minds. (Their adversaries, the Idirans, aren’t terribly relevant to this post.) The Minds are vast, sentient, artificial intelligences with capabilities orders of magnitude beyond human comprehension. Each mind is capable of managing not just a spaceship or a city, but entire civilizations, adeptly navigating hyperspace to integrate information across cosmic scales. In fact, the Minds govern the entirety of the Culture’s civilization.
There is a particular passage in this book that, when I read it, jumped off the page and has stuck with me ever since. The reason for this is because of the profound insights it gave me regarding intelligence or, better put, cognitive effectiveness. The particular passage is in Chapter 4: Temple of Light in a sub-chapter called State of play: one (page 91 in my softcover copy).
There were in excess of eighteen trillion people in the Culture, just about every one of them well nourished, extensively educated and mentally alert, and only thirty or forty of them had this unusual ability to forecast and assess on par with a well-informed Mind (of which there were already many hundreds of thousands). It was not impossible that this was pure luck; toss eighteen trillion coins in the air for a while and a few of them are going to keep landing the same side up for a long, long time.
Leading up to this passage, Banks is describing a scenario between Fal ‘Ngeestra who has a penchant for dangerous mountain climbing and her companion Mind, Jase, which had been assigned to her because of her exceptional intelligence. It turns out that Fal ‘Ngeestra is one of these exceedingly rare but statistically inevitable humans. The passage continues…
Fal ‘Ngeestra was a Culture Referrer, one of those thirty, maybe forty, out of the eighteen trillion who could give you an intuitive idea of what was going to happen, or tell you why she thought that something which had already happened had happened the way it did, and almost certainly turn out right ever time.
You may find it puzzling that while the possibility of a person like this existing is real, it doesn’t immediately resolve how they, a biological intelligence, have a place in a world governed by Minds. Banks explains:
“It fascinated those Minds that such a puny and chaotic collection of mental faculties could by some slight of neuron produce an answer to a problem which was as good as theirs. There was an explanation of course, and perhaps it had something to do with patterns of cause and effect which even the almost god-like power of the Minds had difficulty trying to fathom; it also had quite a lot to do with sheer weight of numbers.”
Jase was Fal’s companion. It was also her lever.
“She was being handed problems and ideas constantly, being both used and assessed herself. Nothing she said or did wen’t unrecorded; nothing she experienced went unnoticed.”
Fiction Becomes Reality
Together, these excerpts from the passage reveal several key insights:
First, in a population of trillions, the far-right tail of the bell curve births minds of extraordinary brilliance, humans with superhuman IQs. These are rare, but a statistical inevitability. It truly is just a matter of numbers. One could imagine, just as Banks does, a world where extreme abundance unlocked by A.I. then delivers the kind of explosive population growth that would therefore yield superhuman IQs.
Second, the Culture, a civilization of nearly infinite A.I. capability, still sees merit in exceptional biological minds, not just as quaint relics but as powerful, nuanced thinkers that can complement machines. So much so that the highest-IQ humans aren’t replaced—they’re enhanced , cultivated , and curated . What I love about this passage is that it resists the easy trope that A.I. makes human intelligence obsolete. Instead, Banks shows us a world where the best minds—organic or artificial—collaborate. Not by merging (another trope), but by optimizing for each other. And part of that optimization is knowing when a human brain is the right tool for the job, provided you feed it well.
Third, and most importantly, this passage implicitly captures the underlying structure that has become my own mental model for cognitive effectiveness. Essentially, its a layered framework with each component stacking together, culminating in a system that produces cognitively sourced output.
The firsts hints of this model appear in Banks’ observations that, in addition to the genetic predisposition for intelligence that we observe on the exceedingly long-tailed bell-curve, “…just about every one of them [are] well nourished, extensively educated and mentally alert,…”. This surfaces a crucial truth: there’s more to biological intelligence than genetically encoded neural wiring.
Moreover, Banks explicitly observes the need for curated information of unmatched quality to maximize effectiveness of rarified biological intelligence. However, he also implicitly observes the conditions for maximally leveraging the response to such high quality input. In the case of Fal, Jase provides her with a curated stream of information to reference against her exceptional mind and is also a symbol of and medium for the societal role that enables her to leverage those insights.
A Three-Layered, Dynamic Model of Cognitive Effectiveness
The best metric that we have of someone’s mental capabilities is the Intelligence Quotient (IQ). Yet, our understanding of the difference between someone’s IQ and their overall effectiveness is encoded into common wisdom. Put simply, someone can have a high IQ and be less effective while someone else can have a lesser IQ and be more effective. This is not a new idea. Behind this understanding there’s certainly a robust mechanism at play.
The model I have converged on over the years attempts to explain, and perhaps reverse engineer, the dynamics of this mechanism. And in doing so, I think it brings clarity to the questions I have asked myself above. In the subsequent posts, I will build on this foundation taken from Banks’ Consider Phlebas and construct a three-layered model of cognitive effectiveness with explanatory power in our universe.
To close this post, I’m providing a first-pass definition of the three layers of cognitive effectiveness. I will go into much greater depth and detail of the model and the inter-layer dynamics I alluded to in the subsequent post(s), but for now, let’s start with some basic descriptions of each of the three layers:
- Physiological Layer – this layer is the best proxy for what we classically consider to be IQ. It is the biological substrate for intelligence, affected first by the genetic lottery and then, after conception, continuously impacted by environmental factors and lifestyle.
- Experiential Layer – this layer captures how human experience over time, both first-hand and through educational transfer, allows us to perceive patterns and distill insights more effectively and more efficiently over lifetimes and millennia.
- Referential Layer – this layer describes the three necessary components for transforming intelligence into outcomes: the ability to ensure the mind is fueled with the highest quality information (i.e. context), asked the most relevant questions (i.e. alignment), and positioned functionally and socially in such a way as to close the loop (i.e. leverage) on their insights.
As you can already see, these layers build upon each other from physiology up to referencing strategy – chaining together to produce an overall degree of cognitive effectiveness. What you will also come to see is how strengths and weaknesses in each layer translate into competitive advantages/disadvantages and strategies that emerge in human behavior. This comes in the next post. But for now, we should reflect on our question:
“How can we not waste a mind?”
Banks shares a fictional future in which there is a framework, however hyperbolic, for how we might approach this. And as we proceed into subsequence posts, I will expand on how my mental model could serve as a more practical guide for not wasting my mind as I transition into the next phase of my career and as we transition into a world of ubiquitous intelligence.
