The Ethics of Pre-Display Consent: A Plain-English Argument

This is the ethics piece. The other articles in this cluster cover what consent-based dating is, how it works, and how it differs from traditional dating apps. This one covers the ethical argument: why pre-display bidirectional filtering is the right baseline, not a "nice to have" or a niche feature.

The argument has three parts. The argument from autonomy. The argument from harm reduction. And a response to the most common counter-arguments. Read in that order.

Part 1: The argument from autonomy

The foundational ethical argument for consent-based dating is autonomy. Autonomy means you have the right to make decisions about yourself, including decisions about who has access to information about you.

In every other domain of life, autonomy over personal information is treated as a default. You decide who sees your medical records. You decide who you give your phone number to. You decide which photos of yourself appear in which contexts. The default is that you control your visibility; access to information about you requires your consent.

Dating apps break this default. By signing up, you agree to have the platform's algorithm decide which strangers see your photos, your name, your bio, your location, and increasingly, your inferred preferences and emotional patterns. You do not get to decide which strangers. The algorithm decides for you.

This is not because dating-app companies are uniquely malicious. It is because the engagement-optimized business model requires the platform to control visibility decisions. If you controlled visibility, you would restrict it, the matching pool would shrink, and engagement would drop.

But the fact that the business model requires removing user autonomy is not an ethical justification for removing it. It is a description of the conflict between the business model and user autonomy. The honest ethical position is that user autonomy should win.

The autonomy argument leads directly to pre-display bidirectional filtering as the architectural standard. If you have the autonomy to control who sees information about you, the platform must allow you to set visibility constraints that the platform enforces. Visibility constraints that are set but not enforced are not autonomy. They are theater.

Part 2: The argument from harm reduction

The second ethical argument is harm reduction. Traditional dating apps produce documented patterns of harm that consent-based architecture would have reduced.

The empirical base:

• 56% of women under 50 on dating apps received unsolicited explicit content in 2024 (multiple studies, including Pew Research)
• Romance scam losses exceeded $1.3 billion in 2024 (FTC)
• The Hinge stalking case (Stephen Matthews, 2020-2023) involved a convicted serial rapist whose profile remained active after being reported for over two years, during which one victim was matched with him again
• The Match Group addiction class action (Oksayan, February 2024) alleges dating apps are designed using dopamine-manipulating features to create "perpetually pay-to-play loops"
• 78% of dating-app users report burnout (Forbes Health 2024)
• 48% of dating-app users report negative experiences including harassment or unwanted contact (Pew Research 2023)

These outcomes are not the result of individual user choices. They are population-level patterns produced by the architecture. The architecture displays profiles to strangers without those strangers being filtered by the displayed user. The architecture allows bad actors to gain visibility to potential victims. The architecture optimizes engagement at the cost of user wellbeing.

Pre-display bidirectional filtering would not have prevented all of this harm. Some of it (catfishing, identity fraud, in-person violence after a date) sits outside the architectural layer. But pre-display bidirectional filtering would have reduced a significant portion of the unwanted-visibility harms.

The harm-reduction argument is not that consent-based dating prevents all dating-app harms. It is that it reduces a structural class of harms that the traditional architecture enables. Reducing preventable harm is an ethical imperative.

Part 3: Responses to common counter-arguments

Four counter-arguments come up most often. Each gets a response.

Counter-argument 1: "User autonomy on dating apps is already protected by Terms of Service consent."

This is the legal-formalist objection. By signing up for a dating app, you consent to the terms, which include the visibility provisions. So your autonomy has been respected. You agreed.

Response: Contract-of-adhesion consent is not meaningful consent. The terms-of-service are not negotiable. The user has no realistic option to use a competing app with better terms because every major app uses the same architecture. The "you agreed" framing collapses when applied to a category where every option requires the same agreement.

Meaningful autonomy requires the user to have real control over specific decisions, not a one-time blanket sign-off. Consent-based architecture provides that. Terms-of-service "consent" does not.

Counter-argument 2: "People do not actually know what they want, so user-set filters produce suboptimal outcomes."

This is the paternalist objection. Users think they want certain things in a partner, but the research shows people are bad at predicting what will make them happy in relationships. Letting users filter strictly may exclude people who would actually have been good matches.

Response: The research the objection cites (Joel et al. 2020, which is the largest study of relationship outcomes ever conducted, with 11,196 couples) actually undercuts the objection more than supports it. Joel found that demographic and stated-preference variables have near-zero predictive value for relationship outcomes. The thing that DOES predict outcomes is psychological process variables (attachment patterns, conflict style, money scripts). These are exactly the variables that consent-based filtering can capture and act on.

The deeper response: paternalism about user preferences is not an ethical alternative to honoring user preferences. If users cannot be trusted to know what they want, the question is who can. The answer historically has been "the algorithm," which has produced the documented harm outcomes above. User autonomy with binding filters is the more ethically defensible position even when individual users make suboptimal filter choices, because the alternative is platform-controlled outcomes that have proven worse at population scale.

Counter-argument 3: "Consent-based dating is too restrictive. People will not find matches."

This is the practical objection. If filtering is binding and bidirectional, the matching pool shrinks dramatically. Users may end up with no matches. The platform becomes useless.

Response: This is an empirical question, not an ethical one, but worth addressing because it shows up in ethics discussions. The early evidence from consent-based platforms suggests that the matching pool does shrink (users see fewer profiles per session) but the conversion rate from match to date and date to relationship is much higher because the matches that survive bidirectional filtering are higher-signal.

The deeper response: a platform that produces fewer but better matches is not less useful than one that produces more but worse matches. The metric that matters for users is whether they find a partner, not whether they see many profiles. The traditional dating-app industry has spent 13 years optimizing for the wrong metric. The corrective is consent-based architecture, even if it means smaller pools.

Counter-argument 4: "This is just a marketing pitch for your company's product."

This is the most common dismissive objection. Of course On Deck Society would argue that consent-based dating is the ethical baseline. They built a consent-based dating app.

Response: True. The argument is being made by the company that benefits from the argument being persuasive. That does not make the argument wrong.

The argument from autonomy is independent of who is making it. The argument from harm reduction is based on empirical data anyone can verify. The responses to counter-arguments engage with the actual content of those counter-arguments. The ethical case for pre-display bidirectional filtering can be evaluated on its merits regardless of which company is making it.

If a different company had made the same argument first, we would still endorse it. The fact that we made it first is the result of the existing companies being unable to make this argument because their business model conflicts with it. That conflict is the structural reason consent-based dating had to be built from the outside.

What the argument implies

Two things follow from the ethical case for pre-display bidirectional filtering.

First, it is the ethical baseline for the entire dating-app industry. Apps that do not offer it are operating below the baseline. They should be expected to either upgrade their architecture or be displaced by apps that meet the baseline.

Second, users have a right to expect it. Not "would be nice to have." Have a right to expect. The rights in the Consent-Based Dating Bill of Rights are the operational version of this expectation.

The ethical argument is the foundation that makes consent-based dating not a feature, not a niche, not a marketing position. It is the new baseline. The fact that the rest of the industry is below it is the rest of the industry's problem.
