The Dreaming (Tjukurpa in Pitjantjatjara, Jukurrpa in Warlpiri) is the Australian Aboriginal knowledge system that encodes ecological, geographical, legal, moral, and spiritual information in a unified cosmological frame…
A team-development framework by Allan Drexler and David Sibbet that describes seven areas from orientation through renewal
A systems archetype where performance standards gradually decline because the reference point adjusts to current performance rather than remaining fixed at the original target
Clicking a whole opens its parts, one level at a time, while the siblings stay folded. This keeps the overview intact instead of trading it for detail, which is the trade a fully expanded tree forces. Show a marker on the closed branches so the reader knows depth exists, and keep the path from the top visible after every open.
A theory proposing interconnected verbal and nonverbal representational systems that can support encoding and retrieval when the representations are meaningful.
A model of bereavement coping that distinguishes loss-oriented and restoration-oriented demands, with movement between them and periods of respite.
The Dual Process Model (DPM) proposes that healthy grieving involves oscillation between two orientations: loss-oriented coping (confronting the grief itself—crying, yearning, dwelling on the deceased) and restoration-or…
Joshua Greene's dual process theory of moral judgment proposes that moral decisions emerge from two competing cognitive systems: a fast, automatic, emotional system (driven by the amygdala and ventromedial prefrontal cor…
Due process requires that before any authority deprives someone of life, liberty, or property, that person must receive notice of the charges against them, an opportunity to be heard, and a decision by a neutral arbiter
Robin Dunbar's finding that human social networks organize into nested layers of predictable size, each associated with different levels of emotional closeness and interaction frequency: 5 (intimate support group), 15 (c…
A proposed layered pattern in personal networks, often summarized by approximate cumulative sizes of 5, 15, 50, and 150 at decreasing average closeness
An organizational application of Dunbar’s proposed layers of social relationships
Dunbar's number is a proposed approximate social-group size associated with the social-brain hypothesis, often summarized as around 150 relationships
Robin Dunbar's research identified nested social layers based on emotional closeness and interaction frequency: 5 (intimate support group — people you'd call in a crisis at 3am), 15 (sympathy group — close friends whose…
A pattern of miscalibration in which lower performers can substantially overestimate their task performance or relative standing; its mechanisms and measurement remain debated.
The ability to reproduce a useful artifact, offering, or output with sufficient consistency
The psychological finding that people's retrospective evaluation of an experience is largely insensitive to its duration—a 3-minute cold-water immersion and a 30-minute one are remembered similarly if the peak intensity…
Duty of care asks: did you owe an obligation to take reasonable steps to prevent foreseeable harm to another person? This is the threshold question in negligence law and, more broadly, in any situation where your actions…
The political science principle that plurality voting systems (first-past-the-post) tend to produce two-party systems, while proportional representation enables multiparty systems
Stretch the clock rather than the org chart. Ask what happened before your data starts and what happens after it ends. Causes that predate your window, and costs that land after it, are invisible to every actor-level or upstream check.
The segment of users who adopt new technology or products before the mainstream, tolerating imperfections in exchange for early access and innovation
Name the observable indicator that tells you the floor is being approached while you still have room to act. It has to be something you can actually see or measure in the moment, not a conclusion you reach afterward.
The information environment where beliefs are amplified and reinforced through repetition within a closed community that excludes dissenting views
Ecological identity is the component of self-concept derived from one's relationship with the natural world
