Separate genuinely shared content (both people need to see and edit) from per-person folders inside the shared brain (private takes on shared projects) from personal-only content (lives entirely in your private brain).
When a document's framing pivots, create a new version (v2, v3, v4...) rather than renaming the existing one. This preserves the historical lineage and lets anyone trace how thinking evolved over time.

A simple two-step operating rule derived from cumulative culture theory: when a problem appears, the first move is never to think — it's to look. Only after exhausting inherited solutions should you generate new ones.
Robin Dunbar's core argument is that human progress isn't built on individual genius — it's built on inheritance. Each generation skips the trial-and-error phase entirely by standing on the solutions of the last.
Stewart-Williams demolishes the lone-genius myth: no single man or civilization fathered the steam engine. Edison didn't invent the lightbulb; he compiled 600 prior attempts and synthesized them at the right moment.
Stewart-Williams argues humans aren't distinguished by raw intelligence but by cumulative culture — the ability to stockpile knowledge across generations.
Stewart-Williams grounds the entire study of human culture in a single guiding assumption: humans are animals who evolved to pass on genes.
Humans evolved first to pass on their genes, but once the capacity for culture appeared, culture became its own evolving system — competing, replicating, and mutating independently of genetic selection.
Western cultural history traces a recognizable arc: Enlightenment reason gives way to Romantic emotion, which hardens into Realism, which rebels into Modernism, which deconstructs into Postmodernism.
Cultural identity is not a single trait but a stack of derived attributes: nationality, ethnicity, religion or ideology, social class, and generational cohort.
Steve Stewart-Williams reframes culture as software: just as apps expand a phone's capabilities, every cultural tool you acquire—language, math, norms, skills—functions as installed code that multiplies what your cognitive hardware can
Single-key (symmetric) encryption uses one fixed-length key to lock and unlock — fast, but you have to secretly hand the key to anyone who needs to read the message.
Most people equate cryptography with secrecy, but confidentiality is just one of four pillars.
Most organizational friction traces back to a single root cause: departments hoarding or filtering information.
The hypothalamic-pituitary-adrenal axis functions as a sequential amplifier: CRH from the hypothalamus triggers ACTH from the pituitary, which then triggers cortisol from the adrenal glands.
A single 41-amino-acid polypeptide, CRH, sits at the top of the HPA axis as the molecular ignition for the body's stress response.
Women who experience luteal phase defects—problems with corpus luteum function—face a significantly higher risk of miscarriage.
Corporate affairs should be understood primarily as a defensive discipline whose core job is shielding companies from reputation damage. The mechanism is proactive brand strengthening, not reactive crisis comms after a scandal breaks.
The coracoid process serves as the origin for three clinically significant muscles: the short head of biceps brachii, pectoralis minor, and coracobrachialis.
The coracoid process is a single anterior projection on the scapula that serves as the shared attachment point for the short head of biceps brachii, pectoralis minor, and coracobrachialis.
Most successful businesses are not built on novel ideas — they're built by relentlessly applying proven smart ideas with better execution than the originators.
Sam Walton built Walmart into the world's largest company despite inventing 'practically nothing.' His competitive edge came from copying every smart idea he encountered and executing it better than the originators.
A mere 2% drop in hydration is enough to noticeably impair both coordination and cognitive performance.
Robert Greene captures an entire cognitive trap in a single sentence: the feeling that strong belief equals truth.
Robert Greene names conviction bias as the tendency to treat the intensity of our belief as proof of its truth.
Smooth muscle in the GI tract generates movement through two distinct contraction modes: peristalsis, the directional wave that propels contents along the tract, and segmentation, the rhythmic local squeezing that mixes contents with
The practical knowledge of how work actually gets done in an enterprise doesn't live in any system of record. It hides in Slack threads, email chains, deal desk calls, and individual employees' heads.
Condyloid joints get their two-plane range of motion from an evolutionary design choice: the articular surfaces are incompletely fused, leaving a large gap between them. That gap is not a flaw—it's the whole point.
Three foundational network components serve different scopes: a router connects separate LANs to each other, a firewall screens traffic to block malicious packets, and a switch links individual devices within a single LAN.
