§ Lexicon

The lab's working vocabulary.

Short, citable definitions of the terms the lab uses across its methods and working reports. Each entry distinguishes a term from its nearest cousin and links to where it does its work. Stable by design, so others can point to a definition; revised in place as the thinking sharpens.
Terms

Twelve terms that recur across the lab. The shared thread is a stance the lab calls steering vs. becoming: designing for the person who decides, not deciding for them.

n.
Narrative compression
A staged reduction of a self-story (paragraph, then sentence, then single word) used to surface its load-bearing element. Distinct from summarizing: the goal is salience, what carries the most weight, not brevity. Method: Compression. Used in Narrative by Design, DartWorld. Related: AI as mirror.
n. / stance
AI as mirror, not advisor
Using AI to reflect a person's own words, patterns, and evidence back to them so they can interpret it, rather than to generate recommendations about what they should do. Distinct from AI advising: a mirror surfaces evidence and returns judgment to the person; an advisor supplies the judgment. Method: AI as mirror. Used in Narrative by Design, Synapse. Related: autonomy-preserving design.
n.
Card-sort triangulation
Cross-checking a person's self-understanding by having them sort the same material in more than one frame, and reading the disagreements between sorts as signal. Distinct from a single card sort: triangulation treats the gaps between multiple sorts, not one sort's output, as the finding. Method: Triangulation. Used in Narrative by Design, Career Design Lab. Related: narrative compression.
n.
Spatial mapping
Representing options or experiences as positions in a navigable space rather than a ranked list, so relationships, distance, and neighborhoods become visible. Distinct from ranking: a map shows the shape of a space and lets the user choose a vantage; a ranking pre-selects one ordering. Method: Spatial mapping. Used in Synapse, DartWorld. Related: the ranked-list problem.
n.
The ranked-list problem
The failure mode in which presenting options as a single ordered list collapses a rich decision space into "what's number one," suppressing exploration and ownership. Distinct from information overload: the issue is not too much information, it is the premature imposition of one ordering. Addressed by spatial mapping. Motivates Synapse. Related: spatial mapping.
n.
Archetype clustering
Grouping people's reflective outputs (journals, sorts, stories) into recurring patterns, to see what is shared across a cohort without flattening the individual. Distinct from personality typing: archetypes are emergent, provisional descriptions of patterns in the data, not fixed boxes assigned to people. Method: Archetypes. Used in DartWorld, Career Design Lab. Related: longitudinal journaling.
n.
Longitudinal journaling
Reflective writing collected repeatedly across a term, not once, so that change over time, not a single snapshot, is the unit of study. Distinct from one-off reflection: the value is in the trajectory between entries. Method: Journaling. Used in DartWorld, Career Design Lab. Related: cohort-scale reflection.
n. / stance
Anchor, then hold space
A two-move facilitation stance: first establish a firm reference point (the anchor), then deliberately withhold direction so the person can do their own sense-making (hold space). Distinct from facilitating as guiding: the anchor is directive, the hold is non-directive, and the skill is knowing when to switch. Used in Inclusive Leadership Lab, Narrative by Design. See field note Anchor, then hold space. Related: autonomy-preserving design.
n.
Autonomy-preserving design
Designing reflective tools so that interpretation and decision remain with the person: the tool surfaces evidence and structures attention, but does not decide. Distinct from nudging: a nudge steers toward a designer-chosen outcome; autonomy-preserving design builds the person's own capacity to choose (a boost). The lab's core design commitment. Grounds AI as mirror. Related: AI as mirror, steering vs. becoming.
n.
The 90-minute constraint
The discipline of designing a complete reflective arc inside a single short session, used as a forcing function for what is essential. Distinct from time pressure: it is a deliberate design parameter that exposes which moves actually carry the work, not an accident of scheduling. Used in Narrative by Design. See field note The 90-minute constraint. Related: narrative compression.
n.
Cohort-scale reflection
Supporting deep reflection across an entire group (for example, a full undergraduate cohort) rather than one motivated individual or a single session. Distinct from one-on-one reflection: the design problem is sustaining depth at scale and across time. Animates DartWorld, Career Design Lab. See RQ 1. Related: longitudinal journaling.
n. / framing
Steering vs. becoming
The lab's organizing contrast: tools that engineer a person toward a chosen behavior (steering, or nudge) versus tools that build the person's own capacity to see and decide (becoming, or boost). Lo/Be Lab works at the becoming end. Distinct from good vs. bad design: both can be rigorous; the difference is where judgment is meant to end up. Central to The Architecture of Becoming. See publications. Related: autonomy-preserving design.
