The bad advice this corrects

Consent gets discussed, across most advice content, as a single binary — either someone consented or they didn’t — with no structure for the situations that don’t sort cleanly into either box: ambiguous silence, impaired capacity, consent given once and assumed to carry forward, consent to one act treated as consent to everything adjacent to it. A binary can’t hold any of that. This library uses a hierarchy instead, and it’s the framework every other piece in this library that touches consent is built on top of.

The DEZAIR standard

Consent is evaluated on two dimensions at once, not one: what form it took, and whether the capacity behind it was actually intact. The hierarchy below ranks forms of consent by reliability — but no form on this list, including the strongest, counts as valid if capacity is compromised. Capacity is the gate every form has to pass through first.

The hierarchy, from strongest to weakest

1. Explicit, specific, contemporaneous verbal consent. A clear yes, to a specific act, given at or near the time it applies. This is the strongest form available — unambiguous, checkable, and tied to the actual moment rather than inferred from something earlier or something adjacent.

2. Clear, enthusiastic, ongoing behavioral consent, paired with the ability to easily stop or redirect. Active, visible participation — initiating, reciprocating, adjusting — where a check-in or a pause would be easy to introduce and clearly welcome if needed. Strong, but weaker than explicit verbal consent because it depends on correctly reading behavior rather than being told directly, and reading behavior always carries some irreducible uncertainty, as covered in What We Can Know From Behavior — and What We Cannot.

3. Passive, unclear, or minimal participation. Not saying no is not the same as saying yes. Going along without resistance can reflect genuine willingness, or it can reflect discomfort with asserting a boundary, social pressure, freezing, or simple uncertainty about what’s happening. This tier is not consent — it’s ambiguity that requires a direct check before anything continues, not a green light to proceed on.

4. Consent inferred from a prior occasion, a relationship status, or an unrelated agreement. A past yes, a marriage, a standing relationship, agreement to one act — none of these extend automatically to a new moment, a different act, or a different circumstance. This tier is explicitly not valid consent for anything beyond what was actually, specifically agreed to, and treating it as though it transfers is one of the more common and most serious errors this hierarchy exists to correct.

A worked comparison

Two scenes, same couple, one week apart. In the first, one partner asks directly — “can I try this” — and gets a clear, specific yes before continuing. That’s tier one: strongest, checkable, tied to that exact moment. In the second, nothing is said out loud; one partner simply continues based on how things went the previous week, reading the lack of objection as agreement. That’s tier four leaning on tier three at the same time — an inference from a prior occasion, backed by nothing more than absence of resistance in the current moment. Nothing about the second scene is malicious, and nothing about it meets this library’s standard either. The fix isn’t complicated: a specific check, even a brief one, moves the second scene from tier four back up to tier one.

The capacity gate

None of the four tiers above are valid if the person’s capacity to consent is compromised — by significant intoxication, by being asleep or unconscious, by an imbalance of power that removes a genuine ability to say no, or by any other factor that impairs the ability to understand, weigh, and freely communicate a choice. A clear verbal yes from someone without the capacity to give it doesn’t count as tier one. It doesn’t count at all. Capacity is evaluated first, before the form of consent is even considered — the full standard for evaluating impaired capacity specifically is covered in Alcohol, Impairment, and Consent: Where the Line Actually Is.

What this looks like in practice

Consistent with the standard:

  • Treating tier three (passive or unclear participation) as a prompt to check in directly, not as sufficient on its own
  • Re-establishing consent for a new act, a new occasion, or a changed context, rather than assuming it carries forward
  • Assessing capacity before considering the form consent took, every time, regardless of relationship length or history

Inconsistent with the standard:

  • Treating silence or lack of resistance as equivalent to a yes
  • Assuming a standing relationship or a past agreement covers a new specific act
  • Accepting an explicit yes at face value without checking whether capacity to give it was actually intact

Edge cases worth naming

Consensual non-consent scenes — where “no” is deliberately part of a negotiated performance — don’t sit inside this hierarchy at all in the moment they’re happening; they operate on a separate, pre-negotiated safety system precisely because this hierarchy’s normal signals are intentionally being used differently. That structure is covered fully in Consensual Non-Consent (CNC): Negotiating the Scene Where ‘No’ Doesn’t Mean Stop — the hierarchy above still governs the negotiation that happens before a CNC scene, just not the in-scene language itself.

Consent at any tier is also revocable at any point, regardless of how it was given or how far along an encounter is. A tier-one yes, given clearly and specifically, does not lock in for the duration of whatever it applied to — a change of mind partway through moves the situation immediately to “no consent,” full stop, with no tier of prior agreement outweighing it.

The standard

Consent this library treats as valid requires both an adequate form — ranked here from strongest to weakest — and intact capacity behind it. Either one missing means the standard isn’t met, regardless of how the other one looks.
