Duolicious | Meet People Who Get You | Date, Make Friends & Chat
Amazingly, you can get a good date matchmaking algorithm from ChatGPT if you forget all those LinkedIn posts about prompt "engineering" and instead apply some statistics to ChatGPT's output.
If you want to know why it works, keep reading, because we're taking a deep dive into the psychology and data science of the Duolicious matching algorithm.
The Duolicious matching algorithm works by finding people similar to you. While a lot of people say, "opposites attract," sociologists have actually found that people tend to date others who are more similar to each other than not. Scientists call that "assortative mating." Surprisingly, even for traits like height, where there's typically a big difference between each partner in a relationship, there's still a correlation between both partners' heights! Here's a chart from a study of two groups of married couples in Cameroon, but assortative mating happens everywhere, even in other species:
While the Duolicious algorithm doesn't take traits like height into consideration just yet, it's still pretty comprehensive. Your quick, yes-or-no answers let Duolicious measure 47 different traits related to personality, political alignment, habits, and so on. We tried to pick traits about you that stay the same over time. Personality traits like the Big 5 and MBTI definitely fit into that category. Surprisingly, political alignment tends to be fairly stable over time too; in fact it's correlated with your personality traits. Although personality traits are generally a bit more stable.
