Dr. Naomi Reyes, a relationship psychologist who studies digital matchmaking, breaks down what compatibility algorithms optimize for, why they favor engagement over long-term fit, and how users can work around their blind spots.

In today’s digital age, dating apps have become a prevalent method for finding love. To delve into the intricacies of these platforms, Priya Anand sits down with Dr. Naomi Reyes, a relationship psychologist based in Austin with 14 years of experience in relationship psychology and algorithmic matchmaking design. Dr. Reyes shares her insights into what dating app algorithms get right—and wrong—about compatibility.


Meet Dr. Naomi Reyes: Studying the Psychology Behind the Algorithm

Priya Anand: Dr. Reyes, thank you for joining us today. Can you share a bit about your background and what led you to focus on dating app algorithms?

It’s important to acknowledge that while algorithms can streamline the process of finding a partner, they can also perpetuate biases present in the user data they are fed. For instance, users from underrepresented demographics might see fewer matches due to historical preferences embedded within the algorithmic design. This can lead to a homogenization of matches where diversity is inadvertently suppressed. Experts suggest that women often report receiving fewer matches compared to their male counterparts, highlighting a gender imbalance in algorithmic visibility. Our comparison of how dating app algorithms actually work provides a deeper understanding of these dynamics.

Additionally, many users are unaware of the “black box” nature of these algorithms, meaning the specific criteria and data points used are often not transparent. This lack of transparency can lead to mistrust and skepticism among users who feel they are not in control of their dating experiences. Furthermore, the algorithms’ reliance on historical data can perpetuate outdated social norms, such as traditional gender roles, which may not align with modern users’ expectations for equality and diversity in relationships.

Key takeaway: Algorithms in dating apps not only suggest matches but also shape our understanding of relationships.


Q&A: What Dating App Algorithms Actually Optimize For

Priya Anand: Let’s dive into the algorithms themselves. What do dating app algorithms actually optimize for?

Dr. Naomi Reyes: Here’s the thing: most dating app algorithms are primarily optimized for engagement rather than compatibility. This means they focus on keeping you on the app by showing profiles that you’re likely to interact with, based on past behavior. For example, our review of Tinder’s swipe-based matching highlights how user activity patterns influence the profiles you see. This engagement-first approach can sometimes lead to a mismatch between the app’s objectives and a user’s long-term relationship goals. Consider the case of a user who frequently swipes right on profiles with similar hobbies; the algorithm learns this pattern and continues to show similar profiles, which might not necessarily lead to a meaningful connection.

Additionally, the focus on engagement can lead to the promotion of profiles that are more visually appealing or that use more engaging content, rather than those that are truly compatible. This can result in a skewed perception of what makes a successful match, emphasizing aesthetics over substance. Users might find themselves caught in a cycle of short-lived interactions that do not meet their deeper relationship needs. To mitigate this, some apps are beginning to incorporate feedback loops that account for user satisfaction post-interaction, but this is still in its infancy and not widely adopted.

Common mistake: Assuming that high engagement equates to high compatibility.

Q&A: Compatibility Scores vs. Real Compatibility

Priya Anand: How do compatibility scores on dating apps compare to real-world compatibility?

Dr. Naomi Reyes: Compatibility scores can be somewhat misleading. They often rely on questionnaire data or user behavior to predict potential matches. However, while they might capture surface-level traits, they don’t always translate to deeper compatibility. For instance, a high score might indicate shared interests but not necessarily shared values or life goals. Our comparison of how dating app algorithms actually work dives deeper into these nuances. It’s crucial for users to remember that a score is just a starting point.

Compatibility ScoreReal-World Compatibility
Shared interestsShared values, life goals
Surface-level traitsComplex dynamics, emotional intelligence
Static assessmentDynamic growth, adaptability

Real-world compatibility involves complex dynamics that algorithms currently can’t predict accurately.

Moreover, compatibility scores may not consider the dynamic nature of relationships, where individuals grow and change over time. This static assessment can overlook the potential for two individuals to develop a strong bond through shared experiences and challenges. Additionally, the pressure to achieve a high compatibility score can lead users to focus on superficial metrics rather than exploring the unique, qualitative aspects of a potential partner. Users should approach these scores with caution, using them as a tool rather than a definitive measure.

Tip: Use compatibility scores as a guide, but rely on personal interactions to gauge true compatibility.


Q&A: Why Swipe-Based Apps and Questionnaire-Based Apps Produce Different Matches

Priya Anand: Why do swipe-based apps and questionnaire-based apps often produce different types of matches?

Dr. Naomi Reyes: Swipe-based apps like Tinder focus on immediate, visual attraction and quick decision-making, which can result in matches based on physical appeal and initial impressions. On the other hand, apps that use detailed questionnaires, such as Hily, aim to match users based on deeper personality traits and compatibility markers. Our full Hily review and its compatibility-first approach illustrates how these platforms differ in their methodology. In practice, swipe apps often lead to a higher volume of connections, while questionnaire-based apps might foster fewer, but potentially deeper, connections.

For instance, a user on a swipe-based app might encounter 100 profiles in a single session, leading to quick decisions based on superficial criteria. Conversely, a questionnaire-based app might present only a few curated matches per day, encouraging users to invest more time in each interaction. This fundamental difference in approach can drastically alter the user experience and the nature of relationships formed. Moreover, the slower pace of questionnaire-based apps can allow for a more thorough exploration of potential matches, which might facilitate more meaningful connections over time. Many relationship experts observe that users of questionnaire-based apps often experience greater satisfaction in their matches compared to those using swipe-based apps.

The contrast between these two approaches also highlights the importance of user intent. Swipe-based apps cater to those seeking quick, casual interactions, while questionnaire-based apps appeal to users looking for long-term commitments. This differentiation can impact user satisfaction, as aligning app choice with personal goals is crucial for a fulfilling dating experience. Furthermore, the psychological impact of each approach varies, with swipe-based apps potentially leading to decision fatigue, while questionnaire-based apps may foster a more deliberate and considered approach to dating.

Checklist: Consider your goals—quick connections or deeper relationships—when choosing an app type.


Q&A: The Engagement Trap — When the Algorithm Works Against You

Priya Anand: Can you explain the “engagement trap” in the context of dating apps?

Dr. Naomi Reyes: Certainly, Priya. The engagement trap refers to how algorithms prioritize showing you profiles that maximize your time on the app, rather than those that might lead to a meaningful connection. For example, if you often swipe right on a particular type of profile, the app will keep showing you similar profiles to sustain your engagement. This can create a feedback loop, limiting exposure to diverse matches. It’s a bit like a social media echo chamber, where you’re continually exposed to the same types of content, reinforcing existing preferences and potentially stifling new experiences.

This engagement-driven approach can result in users feeling stuck in a cycle of repetitive interactions without progressing towards meaningful relationships. Critics argue that this method capitalizes on user habits rather than facilitating genuine connections, akin to the way news feeds on social media platforms are designed to keep you scrolling, not necessarily informed. To break free from this cycle, users must actively seek diverse interactions, challenging the algorithm’s assumptions and expanding their pool of potential matches. For instance, a user might purposefully engage with different profiles to disrupt the algorithm’s pattern, which can lead to a broader range of matches over time.

Signs of Engagement TrapSigns of Genuine Matches
Repeatedly seeing similar profilesEncountering diverse profiles
High volume of interactions, low depthFewer, more meaningful conversations

By being aware of these signs, users can adjust their interactions to foster more meaningful connections and avoid the pitfalls of algorithmic repetition.

Key takeaway: Diversify your swiping habits to avoid algorithmic echo chambers.

Q&A: How to ‘Train’ an Algorithm to Show You Better Matches

Priya Anand: Is it possible to ‘train’ a dating app algorithm to show better matches?

Dr. Naomi Reyes: Yes, to some extent. Users can influence the algorithm by being intentional about their swiping and messaging behavior. For instance, engaging with profiles that genuinely interest you rather than swiping indiscriminately can signal the algorithm to present similar profiles. Additionally, updating your profile regularly with meaningful content can improve match quality. For more on optimizing your profile, see how to write a dating profile that gives an algorithm better signal.

Consider the analogy of a streaming service: the more accurate your input—such as rating shows you genuinely enjoy—the more refined the recommendations become. Similarly, in dating apps, the quality and specificity of your interactions help shape the algorithm’s understanding of your preferences. By being selective and thoughtful in your interactions, you can effectively guide the app towards more suitable matches. This practice not only refines the algorithm but also increases the likelihood of finding a match that aligns with your genuine interests and desires. Experts suggest that users who are intentional about their profile and interaction choices tend to experience more meaningful connections.

Moreover, users can take advantage of app features designed to enhance compatibility, such as detailed profile sections or interest-based filters. By fully utilizing these tools, users can provide the algorithm with more nuanced data, leading to better match suggestions. Engaging in meaningful conversations and providing feedback on matches can also help the algorithm learn and adapt to your preferences over time.

Tip: Consistent and mindful interaction with the app can refine the algorithm’s understanding of your preferences.

Frequently Asked Questions

Do dating app algorithms actually predict compatibility? +
They predict engagement and mutual interest reasonably well, but long-term relationship compatibility depends on factors — communication style, conflict resolution, life goals — that are difficult to capture from swipes, questionnaire answers, or message frequency alone, according to Dr. Reyes.
Why do I keep getting matched with similar types of people? +
Most algorithms weight your past behavior heavily, including who you swipe on and who you message. This creates a feedback loop that can narrow your exposure to a certain type over time unless you deliberately vary your interactions or adjust your stated preferences.
Are personality-questionnaire apps more accurate than swipe apps? +
They tend to front-load more explicit compatibility signals, which can reduce time wasted on clearly mismatched people, but no questionnaire fully substitutes for how two people actually communicate and handle disagreement in practice.
Does being more active on an app improve my matches? +
Activity can increase how often you appear in others' queues, but engagement-optimized algorithms don't necessarily surface better long-term matches — sometimes the opposite, since apps benefit from you continuing to swipe rather than settling quickly.
Can I reset a dating app's algorithm if my matches feel off? +
Most platforms don't offer a true reset, but updating your stated preferences, unmatching consistently poor fits, and deliberately engaging with different profile types can meaningfully shift what the algorithm surfaces over a few weeks.
