Sell-By Dating Apps?

Folk are ever hopeful! There used to be professional matchmakers. Now, plethoras of dating apps are commercially available. All these apps use 'secret' algorithms to predict 'sexual chemistry'. These algorithms appear only capable, however, of producing very rudimentary 'matches'. They can pick out people, who will generally be considered more attractive to a greater number of folk. They can also select people, who will prove generally less 'picky' and might be open to a second date with more contacts. The apps seem to perform no better than chance, however, when predicting actual attraction between two specific people (https://www.theguardian.com/science/2023/feb/12/the-science-of-romantic-chemistry-and-those-not-so-obvious-red-flags). Scientists believe that it's very unlikely that any dating apps have 'stumbled on a secret ingredient, missing from psychological literature'. Perhaps, the most useful information one can have about yourself and a potential partner, is to determine whether a 'romantic destiny' or a 'romantic growth' mindset prevails? The former are more likely to quickly 'fall in love' but are relatively easily discouraged by problems that become apparent later. The latter are initially more pragmatic but are prepared to work on and try to resolve issues. Knowing your own mindset and that of the potential partner, could at least make expectations more realistic.
