"E.g. who do I love, what should I wear/watch/eat, where should I spend my money, etc."
Ok, my feelings of love are not guided by a scientific method (except analyzing and reflect on what I feel).
But by deciding what to wear, eat, watch etc. I do apply the scientific method. Meaning I test out systematically, what works best for me. And I try to teach this to my children.
The scientific method applied to preferences is probably not the scientific method (in regards to control experiments (unless you have clones and access to the multi verse:)))
The very basic idea of the scientific method as I learned it, is: testing ideas by experiment.
If it looks cold outside, but not too cold - I have the idea that a medium warm jacket of mine is enough. And then outside I see if it was adequate or not and next time under similar conditions I change accordingly, or go back to the house that instant.
Sounds like common sense and it is. But not everyone is doing it.
I seriously got shocked by people telling me, they walk in shoes hurting them, but they did so because of style. This sounds like insanity to me, even though I know in their specific setting it makes some sense - as style is important in their circles. But that just means those circles are far from science and rationality, if it leads to people wearing clothes not adequate for the weather and being cold and uncomfortable.
“ I seriously got shocked by people telling me, they walk in shoes hurting them, but they did so because of style.”
Determining what to optimize for is basically what preference is. Some prefer attractiveness and aesthetics over comfort, and in most cases there is no option that optimizes all variables due to complex cross talk…
After you choose which subjective preference to optimize for, you can definitely employ the scientific method to try to parse that further, but that comes after the preference:)

I think I can apply the scientific method also to preferences. Meaning if it really makes me happy, to be accepted in certain circles where the conditions are bad shoes, then so be it.
But personally I decided years ago, that this is not the case for me.
Actually, wanting to be comfortable all the time is irrational. You should intentionally make yourself uncomfortable occasionally in order to avoid becoming too "precious". Hypothermia is an old friend of mine.
