Terms used across this site, in alphabetical order. Where a term belongs to a specific thinker or work, it is attributed. Where it is a cross-source concept built here, that is noted.
The comprehension gap
The failure mode in which those who understand a situation have no authority to act on it, and those who have authority do not understand the situation. Named here for the concept dramatised in Margin Call (2011) and prescribed against in L. David Marquet’s Turn the Ship Around! (2012). The gap is structural, not a matter of individual failure; the cure is structural too: move authority to where the understanding is, rather than hoping the understanding will find its way up to where the authority sits.
The data double
The version of you that a system reads, classifies, and acts on — built from the data it can measure, which is never the whole of what you are. The term is used here in the tradition of Gattaca (1997), where genetic probability becomes destiny, and extended to any system that pre-judges by what it can record rather than what you have done or who you are.
Designed-in dissent
The institutional practice of building a formal mechanism for challenge into a decision process — a role, a protocol, or a rule — before it is needed, so that the authority to question exists even under conditions that would otherwise suppress it. Drawn from the command-verification protocols in Crimson Tide (1995). The opposite of artificial harmony.
The existential vacuum
Viktor Frankl’s term for the distinctive suffering of a life that has comfort, security, and stimulation, but no reason — no meaning toward which the person is oriented. Frankl distinguishes this from ordinary unhappiness; the vacuum is its own affliction, not a symptom of material lack. From Man’s Search for Meaning (1946/1959).
Existential flexibility
Simon Sinek’s term (applied from James Carse’s philosophical framework) for the capacity of an infinite player to hold their cause fixed while shifting their strategy profoundly — to accept major disruption to a current winning position in order to better serve what they are ultimately for. The opposite of clinging to a winning position until it becomes a trap. From The Infinite Game (2019).
The finite mindset trap
Playing an endless game — a career, a market, an institution — as if it were a finite contest with a winner and a finish line. Fixating on the quarterly number, the competitor’s defeat, or “winning” erodes what was being built. The concept derives from philosopher James P. Carse’s Finite and Infinite Games (1986), applied to leadership by Simon Sinek in The Infinite Game (2019).
Fixed and growth mindset
Carol Dweck’s distinction between two beliefs about ability: that it is innate and static (fixed), or developable through effort and learning (growth). The belief is consequential — it governs whether failure is experienced as a verdict or as information, whether challenge is a threat or an opportunity. From Mindset (2006). Note: the mechanism is well-evidenced; the claim that brief mindset interventions reliably improve measurable outcomes has a contested replication record.
The Golden Circle
Simon Sinek’s communication model: three concentric rings of Why (purpose/belief), How (process), and What (product/output), with the argument that influential leaders and organisations communicate from the inside out — leading with why rather than what. A memorable and widely-used communication frame; Sinek is a communicator, not a researcher, and the model is built on selected examples rather than systematic evidence. From Start With Why (2009).
The infinite game
James Carse’s distinction (from Finite and Infinite Games, 1986): finite games are played to end and produce a winner; the one infinite game is played to continue. Sinek applies this to leadership, business, and institutions in The Infinite Game (2019). To play an infinite game with a finite mindset is the characteristic disaster.
Inspect and adapt
The core loop of the Scrum methodology: work in a short cycle, look honestly at the result, and adjust the next cycle based on what you learned. The plan is a hypothesis revised against evidence, not a contract to be obeyed. From Scrum: The Art of Doing Twice the Work in Half the Time by Jeff Sutherland (2014).
Inspiration vs manipulation
The ethical distinction at the heart of this site’s approach to influence. Sinek’s framing (Start With Why, 2009): you can move people through inspiration — a belief they genuinely share — or through manipulation — incentives, fear, pressure, or engineered social proof. Both produce action; only inspiration produces lasting loyalty. Manipulation must be repeated and escalated; it decays the moment it stops. This distinction runs through every piece on leadership, persuasion, and influence on this site. See also: the manipulation line.
“I intend to…”
The mechanism from L. David Marquet’s Turn the Ship Around! (2012): rather than asking permission, crew members state their intended action. The shift in language is a shift in cognition — from passive compliance to active ownership. Three words that quietly redistribute authority from the person who knows least to the person who knows most.
The just cause
Sinek’s term (developed from Carse) for the durable, forward-looking purpose that gives an infinite game its orientation — specific enough to orient decisions, resilient enough to survive the loss of any one person, and aspirational enough to pull people toward a future worth working for. Not the same as a mission statement; more like a condition worth advancing toward. From The Infinite Game (2019). Credit to James Carse for the philosophical frame.
The last freedom
Viktor Frankl’s observation — drawn from his survival of Auschwitz and other camps — that even when everything else has been stripped away, a person retains one freedom that cannot be taken: the freedom to choose their attitude and response to what they cannot control. This is not a denial of suffering; it is the insistence that even the most bounded situation leaves one irreducible choice. From Man’s Search for Meaning (1946/1959). Note: the phrase “He who has a why to live for can bear almost any how” is Nietzsche’s, quoted by Frankl — not Frankl’s original words.
Leader-leader
L. David Marquet’s alternative to the traditional leader-follower model: instead of concentrating decision authority at the top, distribute it to the people closest to the information and the work — making leaders at every level rather than followers. The leader’s job shifts from making decisions to building an organisation full of decision-makers. From Turn the Ship Around! (2012).
The manipulation line
The point at which the techniques of sincere influence — appreciation, genuine interest, seeing it from the other person’s point of view — become manipulation, when the “genuine” is hollow. Carnegie’s methods are useful precisely when they come from authentic respect and interest; they describe exactly what hollow, instrumental charm looks like when they don’t. Every piece on influence and persuasion on this site marks this line explicitly rather than presenting the tactics as neutral techniques.
Move authority to the information
The structural prescription from L. David Marquet (Turn the Ship Around!, 2012) for the comprehension gap: rather than moving information up the hierarchy to where the authority sits (slow, lossy, and the source of most institutional failure), push the authority down to where the information already is. The direct and structural cure for the gap between those who understand and those who can act.
Pre-emption
Acting against someone for what a model says they will do, before they have done it. Abolishing the presumption of innocence in the name of prevention. Drawn from the PreCrime system in Minority Report (2002) — a fictional treatment with real resonance across predictive policing, algorithmic risk scoring, and bail-decision models. Note: the film is analogy; claims about real predictive systems require independent sourcing.
The retrospective
A short, regular, disciplined pause at the end of each working cycle to ask what went well, what didn’t, and what will change. The mechanism by which a team turns its own experience into institutional memory rather than repeating the same mistakes. Part of the Scrum framework (Jeff Sutherland, 2014); the underlying principle — kaizen, continuous improvement — derives from the Toyota Production System.
The Stand Alone Complex
The defining concept from Ghost in the Shell: Stand Alone Complex (2002–2005, dir. Kenji Kamiyama): copycat behaviour can spread through a population with no original to copy — a mass of people independently act as if following a mastermind who never existed. Coordination without a coordinator. The reflexive error is to hunt for the author of a phenomenon that has no author. The cause detaches from the person; the symbol outruns its origin. Drawn from the animated television series; the concept has analytical precision that transfers far beyond its source.
The suppressed minority report
The institutional practice of concealing the system’s own internal dissent in order to project the appearance of certainty and unanimity. Named for the plot device in Minority Report (2002): the precogs sometimes disagree, and when they do, the dissenting vision is hidden because admitting disagreement would undermine the system’s authority. An institution that cannot afford to show its doubt will suppress the doubt rather than temper its claims. See also: artificial harmony; designed-in dissent.
Vulnerability-based trust
Patrick Lencioni’s definition of the foundational trust a team requires: not the confidence that colleagues are competent and reliable, but the willingness to be seen as imperfect — to say “I was wrong,” “I need help,” or “I don’t know.” Without vulnerability-based trust, people protect themselves rather than the work, and every higher team function is compromised. The first layer in Lencioni’s five-dysfunction model. From The Five Dysfunctions of a Team (2002). Note: the model is a leadership fable, presented as such by Lencioni — a diagnostic heuristic, not a validated causal mechanism.
The worthy adversary
The recognition that an opponent or competitor who is formidable, principled, and capable is a source of improvement rather than an enemy to eliminate. Drawn from three sources that converge on the idea from different angles: the chivalric diplomacy in Kingdom of Heaven (2005), the mutual recognition between Cold War adversaries in Bridge of Spies (2015), and Sinek’s “worthy rivals” framework in The Infinite Game (2019) — competitors whose strengths reveal your own weaknesses and make you better for existing.
