Cute. Of course, beyond basic deal breakers, neither do people know their preferences (but they think they do), nor do the majority of preference categories actually matter.
This is a common problem with all dating apps. Specifically, interests, hobbies, daily routines, objectives, etc. have nothing to do with compatibility.
“We like the same things!” is the compatibility signal of a naive 22-yr old…

  What signals do you suggest? Regardless of whether it's feasible to put them in the dating app.

    The OkCupid guys figured out that it was (potential) that best predicted stable relationships and everything else was just a proxy for that feature. Similar/compatible education level? Just a proxy for income. Similar/compatible hobbies? Guess what, also a proxy for income!

    Or income is a proxy for, say, intelligence.

    It clearly isn't.
    In Germany, there is a reason why the term "akademisches Prekariat" (academic precariat/precarity) exists, meaning that people who stay in academia are often in a precarious job situation and are paid quite badly. But these people are very intelligent and well-educated.

    It is, if you define intelligence as "how to do well in life" and not as "here are 5 ways how Germany could have won the war in 1943".

    "Intelligence" is a term that is defined very precisely in psychology (psychometrics):

    That doesn't really contradict what I said. This definition of intelligence can be useful in some contexts, but on average neither women nor capital are particularly attracted to people who have it

    This is actually a reformulation of the point that I made in <a href="https://news.ycombinator.com/item?id=49920421">https://news.ycombinator.com/item?id=49920421 that income is not a proxy for intelligence. :-)

    Was my point really that hard to follow? I'm not saying "intelligence" in the strict psychological definition of the word. I mean, perhaps, the thing they claim was the independent variable was in fact a proxy for something else I hypothecated as "intelligence", by which I really meant some as yet undefined thing that on average leads to higher incomes, which could be intelligence in the colloquial sense, because that sort of has that trait and is pretty influential in attractiveness.

    What you are looking for is "dark triad traits", i.e.
    - machiavellianism,
    - (sub-clinical) narcissism, and
    - (sub-clinical) psychopathy.

    These are quite correlated to higher incomes and higher-status jobs.
