Intelligence & Innovation — Working Definitions
Intelligence is a basket of capacities: fluid reasoning, crystallised knowledge, working memory, attentional control, metacognition, and transactive memory (knowing where information lives and who holds it). Not all are trained equally by modern life.
Innovation density asks: how much breakthrough per person (or per researcher) do we get? Absolute totals rise with population; but we care about the per-capita gradient—how much a typical engaged mind carries internally in each era.
Constraint profile: the bundle of scarcity, tools, risks, and institutions that a culture faces. Constraint profiles sculpt the type of intelligence a society trains by default.
Plateaus & the Google-Effect — The Modern Puzzle
For much of the 20th century, IQ test scores climbed (the “Flynn Effect”). Recent work shows plateaus or reversals for cohorts in several rich countries—likely environmental (education quality, reading depth, digital habits, nutrition). Simultaneously, research in cognitive psychology shows we now remember where information is (search, bookmarks) more than the facts themselves—“transactive memory” amplified by the internet.
In parallel, macro-innovation studies find that it takes more researchers and capital per unit of frontier progress—i.e., “ideas are getting harder to find.” None of this means we’re regressing overall; but the default environment no longer builds certain capacities unless we design for them.
Age I — Paleolithic: Working Memory in the Wild
“A brain shaped by scarcity learns to compress the world.”
Signature Capacities
- Procedural memory & embodied geometry: Flint-knapping, bow-making, and sinew binding encoded angles, torsion, fracture mechanics—without notation.
- Ecological inference: Reading tracks, scat, wind, and cloud formations demanded Bayesian-like updates under uncertainty.
- Social cognition: Coalition management, reputational memory, and teaching-by-demonstration (mirror-neuron heavy learning).
- Orality as compression: Myth and story preserved laws, maps, and ethics in memorable packets (meter, rhyme, archetype).
Innovation Profile
From Oldowan to Acheulean handaxes, to Levallois and Mousterian flakes, tool traditions improved across millennia—evidence of cumulative cultural evolution. Fire control transformed diet and time budgets; tailored clothing expanded habitable zones; composite tools multiplied force.
Per-Capita Insight
Per person, the internal knowledge load (seasonal routes, water sources, edible/poisonous flora, animal behavior, sky patterns) was enormous. Failure had immediate costs; feedback loops were tight; expertise was embodied and socially verified.
Age II — Neolithic: Memory Palaces Become Villages
Signature Capacities
- Systems thinking: Agriculture bundled soil, seed, weather, pests, and storage—turning time into an asset via calendars and granaries.
- Proto-accounting: Tokens, tallies, and early ledgers externalised memory of debt, tax, and inventory.
- Architecture & logistics: Settlements required shared norms for sanitation, storage, water, and defense.
- Ritual as protocol: Seasonal festivals embedded resource rules as cultural “if/then” automations.
Innovation Profile
Selective breeding, irrigation, pottery kilns, weaving, and megalithic alignments. The cognitive revolution here is temporal governance: sow, wait, harvest, store—repeat—with risk-hedges like crop diversity and communal norms.
Per-Capita Insight
Villages turned personal memory into civic rhythm. Knowledge went from “in the head” to “in the village”: calendars, rules, storage architectures—yet each person still shouldered substantial knowing-by-doing.
Age III — Bronze: Alloyed Intelligence
Signature Capacities
- Materials intuition: Controlling heat, air, and fuel to coax copper and tin into bronze—error-tolerant but unforgiving at scale.
- Long-range logistics: Tin scarcity birthed trade corridors and trust protocols; caravans and ships became knowledge arteries.
- Writing as RAM: Cuneiform and hieroglyphs preserved contracts, law, and grain flows, enabling bureaucratic complexity.
Innovation Profile
Bronze blades and ploughs, advanced hulls and sails, standardised weights and measures, fortified cities, and early codified law. Scribes were living servers; smiths were materials engineers.
Per-Capita Insight
Where stone demanded dexterity, bronze demanded networks. The typical craftsperson or trader navigated materials, routes, currencies, and rulers—intelligence stretched across metallurgy, geography, and law.
Age IV — Iron: Mass Innovation via Cheap Metal
Signature Capacities
- Process optimisation: Higher temperatures, bellows control, quenching cycles—proto-thermodynamics in forges.
- Infrastructure engineering: Roads, bridges, aqueducts, sewers—surveying and load management at civilisational scale.
- Abstract money: Coins trained populations to think in portable value, enabling price systems, taxes, and markets.
Innovation Profile
Iron-tipped ploughs, standardized military gear, road networks, and widespread coinage. Alphabets spread literacy beyond palace walls, accelerating administrative cognition.
Per-Capita Insight
Iron’s cheap durability shifted intelligence toward scaling—standard parts, repeatable processes, and the mental habits of system maintenance.
Age V — Classical: Rationality Meets Empire
Signature Capacities
- Formal thought: Logic, geometry, rhetoric, and law as civic skills, not niche specialisations.
- Institutional cognition: Democracies, republics, and bureaucracies as thinking machines built from citizens.
- Library infrastructure: From scroll rooms to the Library of Alexandria—memory centralisation as strategy.
Innovation Profile
Euclidean geometry, Archimedean mechanics, engineering of aqueducts and harbours, numeracy exchanges across the Mediterranean and India/China. Cross-pollination via trade routes made idea transfer a standard feature of civilisation.
Per-Capita Insight
Participation required public reasoning and memory. A citizen’s toolkit blended law, rhetoric, and arithmetic—an everyday polymathy of civic life.
Age VI — Axial: Civilisational Software
Signature Capacities
- Ethical abstraction: Canonical texts and philosophies (Analects, Upanishads, prophetic literature, Platonic dialogues) encoding universal principles.
- Dialogical method: Socratic debate and commentarial traditions that trained disciplined argument.
- Scriptural literacy: Memorisation and exegesis—deep recall and interpretive flexibility.
Innovation Profile
Paper in China, alphabetic refinements, religious and philosophical institutions that scaffolded civilisational identity and social trust.
Per-Capita Insight
Intelligence here is moral-philosophical: the average learned person engaged in ethical reasoning far beyond modern hot takes—habits of careful reading and slow argument.
Age VII — Medieval: Hidden Mechanics of a “Dark Age”
Signature Capacities
- Mechanical ingenuity: Water- and wind-power, cams, gears, and escapements culminating in mechanical clocks.
- Scholastic discipline: Thesis–antithesis–synthesis disputations as routine training in logic.
- Agro-innovation: Heavy plough, horse collar, three-field rotation—ecological optimisation.
- Manuscript culture → universities: From scriptorium to faculty—structured knowledge networks.
Innovation Profile
Gothic architecture (buttresses, vaults), eyeglasses extending productive life, blast furnaces, algebra transmitted via Arabic scholarship, paper-making, and navigational aids. The era standardised time and study.
Per-Capita Insight
Embodied mechanics + disciplined discourse: citizens and clergy lived inside time systems, craft guilds, and argumentative curricula—heavy cognitive load distributed across daily life.
Age VIII — Renaissance: Cognitive Fusion
Signature Capacities
- Polymathy: Artists-engineers (da Vinci) combined anatomy, hydraulics, optics, fortification design—one brain, many labs.
- Visual-math synthesis: Linear perspective trained geometric imagination across the populace.
- Print literacy: Gutenberg-scale reproduction multiplied critical reading and comparison.
- Navigation: Astronomy + cartography + ship design integrated into global exploration.
Innovation Profile
Oil painting, anatomical science, double-entry bookkeeping, world-mapping, and heliocentric challenges. Feedback cycles accelerated: ideas moved via print and sea lanes.
Per-Capita Insight
Atypical today but common then: one person mastering art, mechanics, and measurement. The default educational diet fed breadth and recombination.
Age IX — Early Modern: Empiricism & Exchange
Signature Capacities
- Scientific method: Structured hypothesis → experiment → observation—truth by test, not tradition.
- Financial abstraction: Stock exchanges, joint-stock companies, and insurance—probability and risk as everyday reasoning.
- Navigation at scale: Celestial fixes, chronometers, and hull design—applied physics at sea.
- Statecraft & law: Treaties, standardised taxation, postal networks—literate governance.
Innovation Profile
Telescopes, microscopes, calculus, modern banking, newspapers, constitutional thinking. This era wired societies for evidence and exchange.
Per-Capita Insight
Merchants, sailors, and scholars shared an unusual overlap: many could reason about risk, navigate oceans, and read technical pamphlets—dense intellectual participation beyond today’s passive consumption.
Age X — Industrial Revolution I (1700–1850): Fire Becomes Code
“Steam was the first software—encoded in pistons, calibrated in pressure.”
Signature Capacities
- Mechanical abstraction: Translating fuel and pressure into predictable work cycles.
- Thermodynamic reasoning: Watt and contemporaries inferred laws of energy through experiment before they were formalised.
- Process scaling: Factory systems demanded scheduling, shift discipline, and throughput optimisation.
- Applied chemistry: Textiles, metallurgy, and explosives required empirical control of reactions.
Innovation Profile
Steam engines, power looms, railroads, canals, and early chemical industries. Infrastructure compressed time and space: journeys shrank, cities grew, and coordination demands soared.
Per-Capita Insight
Per individual, machinists and engineers embodied physics daily—every miscalculation meant breakdown or death. Today’s digital tools abstract these risks away; then, they were muscle memory and judgement calls.
Age XI — Industrial Revolution II (1850–1914): Electricity, Steel, Mass Production
“When wires carried lightning into lamps, the night became optional.”
Signature Capacities
- Electrical reasoning: Edisons and Teslas imagined invisible currents and fields—populations learned to trust unseen infrastructure.
- Industrial chemistry: Synthetic dyes, fertilisers, and explosives demanded atomic intuition.
- Workflow optimisation: Assembly lines introduced systems-level efficiency logic.
- Urban engineering: Grids, sanitation, skyscrapers—civilisation-scale problem-solving without digital modelling.
Innovation Profile
Light bulbs, telegraph, telephone, steelmaking, internal combustion, sanitation systems, metros. Cities transformed into 24/7 networks.
Per-Capita Insight
Electricians, chemists, and engineers trained populations to handle invisible abstractions daily. The mental leap from mechanical to electrical-molecular reasoning raised average applied IQ.
Age XII — Industrial Revolution III (1945–1970): Electronics & Early Computing
“When switches shrank to silicon, thought itself became a circuit.”
Signature Capacities
- Signal logic: Radio, radar, and transistor work demanded deep circuit-level reasoning.
- Information theory: Shannon’s mathematics trained populations in probability and noise reduction.
- Nuclear reasoning: Citizens absorbed concepts of fission, fallout, existential risk.
- Automation: Factories integrated electronics and control theory—feedback systems became universal.
Innovation Profile
Transistors, mainframe computers, satellites, nuclear power, antibiotics, jet aircraft. Humanity entered a planetary nervous system era.
Per-Capita Insight
A 1950s radio technician understood concepts many modern device users never touch. Average citizens learned about fallout, decibels, and jet-age physics in newspapers. Internalisation was high.
Age XIII — Industrial Revolution IV (1970–Present): Digital & AI
“When memory moved to silicon and cloud, intelligence became outsourced.”
Signature Capacities
- Computational abstraction: Millions learned to think in algorithms and code.
- Network reasoning: TCP/IP, packet switching, cloud—society-scale invisible infrastructure.
- Algorithmic design: Search, feeds, recommender systems shaping perception.
- Cognitive offloading: Outsourcing memory, navigation, and calculation to devices.
Innovation Profile
Microprocessors, internet, smartphones, cloud, deep learning. Knowledge externalised at planetary scale, yet individual mastery optional.
Per-Capita Insight
Collective intelligence is maximised. But the individual’s internal load may be lighter: survival no longer demands recall of maps, recipes, or formulas. Intelligence plateaus unless deliberately trained.

- AI as sparring partner: Treat AI as gym equipment for reasoning, not as a crutch.
Extended Narrative: The Secret History of Human Genius
“The myth of progress is not a straight line—it is a spiral, where each turn hides both ascent and forgetting.”
Stone struck flint. Each shard carried geometry and memory in one blow. Bronze smiths turned fire into contracts, trade, and weapons. Iron scaled roads and empires. Classical minds reasoned in public squares, Axial sages in scriptures. Medieval guilds and universities embedded mechanics and argument in daily life. Renaissance polymaths fused art and science; Early Modern merchants fused empiricism and risk. Industrialists encoded physics in pistons and wires. Twentieth-century citizens lived inside nuclear probabilities and electronic signals. Twenty-first-century humans scroll feeds, offloading recall to servers, outsourcing maps to satellites, outsourcing reasoning to models.
Never have we known so much together. Never have we risked knowing so little alone.
Each age built the intelligence it required. Hunters memorised; farmers synchronised; traders abstracted; philosophers reasoned; machinists engineered; coders abstracted. Our age demands synthesis, restraint, and design—not to out-compute AI, but to ask what it cannot. The spiral continues. Whether it ascends or flattens depends on what we choose to carry again in our own minds.
