E.g. who do I love, what should I wear/watch/eat, where should I spend my money, etc.
Our culture has now taught a few generations that people get to decide their own truth, and they conflate preference for truth, and now we are witnessing what this means…
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.
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.
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.
And people usually look at me strangely when I wear just a light jacket, when they look like Inuit.
But I would never intentionally wear shoes that do not fit right. There is no benefit in that - but it rather can mess up your whole body.
I wish. And sometimes they do.
But there are lots and lots of people who have various religious/ideological dogmas. They do not show their kid the scientific method - they preach their truth to them. Because they feel they are right.
