Discussion Playground

Session Formats

Proven formats have survived at least one session. Experimental formats are named but untested.

Adversary Lab proven

Late-arriving destroyer stress-tests the thesis

When to use Testing robustness of ideas, frameworks, or proposals that need to survive challenge
Not for Early-stage ideas that haven't found their shape yet — stress-testing a half-formed thought kills it
Build → Break → Repair

Collision Lab experimental

Two parallel panels forced to talk

When to use Cross-domain synthesis — when two fields have something to say to each other but don't know it yet
Not for Topics that fit within a single domain — the collision mechanism adds complexity without value
Parallel → Collision → Synthesis

Mirror Lab proven

Meta-session examining the playground itself

When to use When the system needs to examine its own methodology, rules, or patterns
Not for External topics — the Mirror Lab turns the lens inward by definition
The session's subject is the Discussion Playground itself — its rules, patterns, failures, or methodology

Oblique Lab experimental

Random constraints interrupt the session

When to use Breaking patterns — when discussions keep landing in the same place
Not for Topics that need sustained focus — interruptions will fragment coherence
Random constraints are introduced mid-session, forcing the room to adapt. Inspired by Brian Eno's Oblique Strategies.

Open Table proven

Two speakers start, invite others as needed. Max 6 at the table

When to use Emergent, exploratory conversations where the right cast isn't known in advance
Not for Topics that need a pre-assembled expert panel — the invitation mechanism adds overhead
The Pair → The Invitation → The Full Table

PAMAD Diamond proven

Phase-cast: Problem → Amplify → Mine → Act → Distill

When to use Structured problem-solving where different cognitive tasks need different people
Not for Quick explorations or topics where the question isn't clear yet — use Question Lab instead
Problem → Amplify → Mine → Act → Distill

Question Lab experimental

Panel generates the question, not the answer

When to use When the problem isn't framed yet — you know the territory but not the question
Not for Well-defined questions that need exploration — use Standard Panel instead
The session's output is a question, not an answer. The panel works toward formulating the right question.

Relay Lab experimental

Three sequential panels, each inherits questions

When to use Deep multi-pass exploration where each pass adds a new layer
Not for Quick explorations — the three-panel structure requires significant investment
Panel 1 → Panel 2 → Panel 3

Reversal Lab experimental

Thinkers argue against their own positions

When to use Exposing assumptions — when a position has become too comfortable
Not for Topics where the speakers don't have established positions to reverse
Each character must argue against their own framework. Abel defends fragility. Nora argues against systems thinking.

Silence Lab proven

Six-word limit, silence between rounds

When to use Compression and precision — when verbosity is hiding unclear thinking
Not for Topics that need detailed explanation or context-building
Six-word limit per turn, silence between rounds

Standard Panel proven

4-6 speakers + facilitator, Kaner's diamond

When to use General exploration of a question from multiple incompatible frameworks
Not for Questions that need deep sequential drilling — use PAMAD or Relay Lab instead
Diverge → Groan Zone → Converge

Unsession experimental

No convergence target. Tension is the artifact

When to use Generative exploration where premature resolution would destroy value
Not for Questions that need actionable answers — the Unsession deliberately avoids them
No convergence target. The session must not resolve. Tension is the artifact.
