Three Teachings Integration (Sanjiao Heyi)
The Three Teachings — Confucianism, Daoism, and Buddhism — coexisted in Chinese civilization for over a millennium, producing the syncretic principle sanjiao heyi
Cognitive Move
Three Translations
When you can't tell whether your framing or your format is failing, encode the same content in three media and run the same task on each.
Cognitive Move
Threshold
Find the level where the loop's behavior flips. Below some quantity the circuit stays quiet and self-corrects; past it the same mechanism runs away or locks up. Name that number and say which side you are currently on.
Cognitive Move
Threshold to reach
Outcomes with a stated minimum bar you have to clear, after which extra performance earns nothing. Below the line the plan fails; above it, stop pushing and spend your effort elsewhere. Name the number or the test that says "cleared."
Cognitive Move
Thresholds
Set, in advance, the exact numbers that convert a result into a decision: the level that counts as a win, the level that counts as a loss, and the dead zone in between where you admit the test settled nothing.
Cognitive Move
Throughput stalls or queues
Work, decisions, or recovery pile up behind one limiting step, and the pileup itself makes the limit worse.
Mental Model
Tianxia (All Under Heaven) Worldview
Tianxia ('all under heaven') is the Chinese civilizational worldview of universal inclusion rather than nation-state exclusion
Mental Model
Tight Coupling Trap
The system design failure where components are so interdependent that change or failure in any component immediately affects many others, eliminating the system's ability to absorb shocks, adapt to change, or fail gracef…
Mental Model
Time Horizon
A time horizon is the future period included when comparing choices and consequences
Mental Model
Time to Convergence and Optimality
Time, convergence, and optimality are distinct features of a decision procedure
Mental Model
Time Value of Money
Time value of money compares cash flows at different dates using an explicit rate and assumptions
Mental Model
Time Value Of Shipping
A product-management heuristic: delivering a useful result earlier can create additional time for benefit and feedback
Mental Model
Timeboxing Protocol for Meetings
A meeting management protocol that assigns fixed time blocks to each agenda item and enforces them strictly, preventing discussions from expanding to fill available time
Cognitive Move
timeline
Events as marks on a single axis where distance is elapsed time. The whole discipline is that the spacing has to be honest. If you space the marks evenly because it looks tidier, you have deleted the one thing this form knows that a list does not. Anything that lasted rather than happened gets a span instead of a point, with its length written on it.
Cognitive Move
Timeline
Lay the material out along a time or process axis, so you can see order, phases, handoffs, and where the waiting happens. Choose it when the question is "what came before what" or "where does this stall," not "which option scores higher."
Cognitive Move
Timestamped rivals
List every competing explanation by name, and stamp each with the date you wrote it, before any results arrive. The date is the point. It fixes the field of contenders so nobody can add or drop one after the numbers land.
Cognitive Move
Timing
Move the same action earlier or later on the calendar. You keep the order of steps and the trigger untouched and only slide the clock, asking which moment gives the action better odds: sooner, later, or a specific date.
Mental Model
Tiny Habits Method (Fogg)
BJ Fogg's Tiny Habits method proposes that behavior change succeeds when the desired behavior is so small it requires almost no motivation
Mental Model
Tip of the Nose Perspective
The tendency to overweight what's immediately visible and underweight what's distant or abstract—a metaphor for the bias toward proximate over distal information
Mental Model
Tipping Point
Tipping-point thinking examines whether a small change can substantially alter a process through feedback, thresholds, or changing expectations
Mental Model
Tipping Points (Mathematical)
Mathematical tipping models specify conditions under which a small change substantially alters a system's future behavior
Mental Model
Tit-for-Tat Strategy
A repeated-game strategy that begins with cooperation and subsequently copies the partner’s previous move.
