    Will Tinder be blamed for the sudden decline in fertility rate? Is there any other plausible explanstion to South Korea’s sudden and dramatic drop in fertility rate to 0.8? No matter how bad the housing market is or the job market is, there has never in history been such a drop in population.

      Yes, dating apps turbocharge hypergamy. It is not a secret that the top 10% of men get a huge share of the likes received.

      Edit:

      Share of all likes received according to ChatGPT

      Top 1% 16.4%

      Top 5% 41.1%

      Top 10% 58.0%

      Top 50% 95.7%

      Bottom 50% 4.3%

        Male hypergamy and polygyny has been practiced by many cultures historically. They had many problems, but low birth rates wasn’t among them. I don’t think dating apps are a sufficient causal explanation alone for low birth rates

          Humans are naturally polygamous like the other great apes and mammals. When men (as in, male humans) realised this, they concluded that women were entirely to blame for it and sought to control their behaviour. This eventually got woven into their religions and for some time women's behaviour was controlled, or at least became shameful and taboo. Many things have happened more recently:

          * Feminism,

          * Decline of religion,

          * Rise of state and law, particularly around male responsibilities towards children,

          * Effective contraception,

          * Dating apps.

          Take all of this together and we're basically reverting back to our natural polygamy, but without all the pregnancies.
