With today's advanced technology, searching for a partner has evolved into a science of data matching, which is the key to the efficient operation of dating websites. Assistant Professor Chu (Ivy) Dang from the HKU Business School has researched message matching on online dating platforms and found that preferences often vary widely. Users who are fixated on their "dream partner" criteria may miss out on their true match.
With Valentine's Day approaching, online dating platforms have become tools for many to find love. However, these platforms face challenges such as user preference differences and low matching efficiency. Dang's research indicates that preference mismatch is a significant barrier to successful matches. She notes that everyone has a definition of their ideal partner, termed a "dream partner." For instance, data shows that men typically prefer women who are about 10 centimeters shorter and younger, with pretty appearance, while women often favor men who are 20 centimeters taller and possess economic stability and compatible values. This "ideal height difference" and preference variation often lead to mismatched choices, lowering the success rate of matches. In reality, one's true soulmate may not meet all ideal criteria.
More Information Isn't Always Better
Contrary to the common belief that more information leads to better choices, Dang's research indicates that excessive information on online dating platforms can have the opposite effect, reducing matching success rates. She explains that when self-introductions are overly detailed, users may prematurely eliminate potentially suitable matches based on minor traits. For example, a woman who has never owned a pet might reject a match simply because the other person likes pets, even though she could grow to accept or enjoy having pets in the future. Similarly, male users might feel pressure if a potential match has a higher income and choose to disregard them.
Dang suggests that many preferences or biases can change as relationships deepen. Premature filtering causes users to miss out on genuine happiness. To address this issue, she proposes a "phased information disclosure" approach. In the initial stages, dating platforms could display only basic attributes like age, location, values, and life goals, allowing users to make choices based on core criteria. As interaction progresses, more detailed information—such as interests, personality traits, and life details—could be gradually unlocked. This design would effectively reduce the chances of missing potential partners due to unimportant details, allowing users to focus on truly significant matching factors.
Furthermore, platforms could incorporate "compatibility weighting" to prioritize recommending matches with high preference overlaps, rather than relying solely on popular tags. During user registration, platforms could inquire about the characteristics they value (such as values and life goals) to enhance the precision of recommendations.
Dang advises users to emphasize core values when presenting personal information, clearly stating their values and life goals instead of simply piling on tags. Descriptions should be authentic and unique, avoiding generalized phrases like "I love to travel." Instead, users should specify personal traits, such as "I hike a mountain every month" or "I visit a new city every quarter." Such details can better convey individual characteristics and lifestyles.
