Key Principle

Safety, opt-out, and calibration are three distinct categories of player-protection mechanics that must not be conflated. Each addresses a different need, and gaps in any category create predictable failure modes.

Why This Matters

A larp with safety words but no opt-out design traps players who need to leave for non-emergency reasons. A larp with opt-out but no calibration forces binary stay/leave choices when adjustment would suffice. Conflating the categories produces systematic gaps in protection.

Core Frameworks

Three-Part Taxonomy:

  1. Safety mechanics -- prevent or react to dangerous situations (e.g., stop word, "cut")
  2. Opt-out mechanics -- allow leaving scenes regardless of character logic
  3. Playstyle calibration -- control over manner and intensity of engagement (physical, playstyle, story levels)

Three Conditions for Genuine Opt-Out: Participants must be able to leave physically (no restraints), socially (no pressure making departure unacceptable), and diegetically (the fiction permits the character to leave). All three must be present simultaneously.

Intrusive-Discreet Spectrum: Discreet mechanics preserve immersion but fail under stress. Intrusive mechanics break flow but are reliable. Design rule: when in doubt, err toward intrusive.

Consent as Continuous Process: "As one can never know in advance exactly what the ensemble of players and organisers will do during a larp, it is not possible to give informed carte blanche consent. Therefore it must be possible to renegotiate and withdraw consent at any time." (Ch. 1)

Calibration as Dual-Function Tool: Calibration prevents negative experiences through negotiation and empowers players to initiate scenes they would otherwise avoid. Without calibration tools, players default to avoidance.

Good Examples

  • Conscience (Spain, 2018): Android players said "battery low" to leave -- simultaneously diegetic action and out-of-character signal. Zero social cost opt-out.
  • BAPHOMET (Denmark, 2018): Invisible discreet gestures (scratching arm/calf) for calibration.
  • Inside Hamlet (Denmark, 2015): Verbal codewords ("rotten"/"pure") as mid-spectrum calibration.
  • House of Craving (Denmark, 2017): Workshop deliberately nastier than the game itself -- if you survived the workshop, you knew you could handle the game.
  • Just a Little Lovin' (Norway, 2011): Feather metatechnique as aesthetically integrated, easily-declined invitation keeping negotiation diegetic.

Counterpoints

  • Safety mechanics alone don't make a larp safe. They must be embedded in player selection, expectation management, play culture design, and pre-larp calibration. "Without a good overall design, safety mechanics can still make the larp feel safer, and your participants behave more bravely: but you might actually be creating a false sense of security." (Ch. 3:4:2)
  • One-handed signaling principle: out-of-character gestures should require only one hand because hands may be busy or restrained.

Key Quotes

"Always workshop your safety mechanics together before the runtime; otherwise, they are unlikely to be used. That would be worse than no mechanic at all, since it will make participants feel safer than they are." (Ch. 3:4:1)

"To be able to opt out of a scene, participants need to be physically, socially, and diegetically able to leave." (Ch. 3:4:1)

"Leaving should have no social cost for the participant or the character." (Ch. 3:4:1)

"A mechanical system or design element that has worked very well for one larp might be in conflict with the goals and content of another." (Section 3:4)

Rules of Thumb

  1. Unworkshopped safety mechanics are worse than no mechanics at all
  2. Err toward intrusive over discreet when designing safety tools
  3. All three opt-out conditions (physical, social, diegetic) must be present simultaneously
  4. Safety design is a system, not a feature -- it includes player selection, culture design, and expectation management
  5. Calibration empowers as much as it protects -- players initiate scenes they would otherwise avoid
  6. Pre-calibrating intensity by making the workshop exceed the game's intensity inverts the trust problem
