> A study published last year, for instance, examined medical data from 360,000 light-skinned Brits and found that greater exposure to UV radiation—either from living in Britain’s sunnier southern bits rather than the darker north, or from regularly using sunbeds—was correlated with either a 12% and 15% lower risk, respectively, of dying, even when the raised risk of skin cancer was taken into account.

Emphasis on “may” - this is hardly a gold standard study. Living in sunnier/warmer climates as a proxy for UV exposure as opposed to lifestyle differences afforded by such a climate, regional culture differences, etc. makes all of this very dubious to me.

I’m going to keep wearing my sunscreen most of the time when I need to be in direct sun, and continue regular screening for skin cancer.

Sun good

Science is good, but restraining all decisions behind FUTON biased double-blind longitudinal meta-analysis is not only unreasonably cognitiviely expensive, but not even the greatest idea.

When making decisions to personally guide your life, you can also base them on values, heuristics, paternal advice, common wisdom, etc...

It's obvious that the ideal amount of sunlight is somewhere between 0 and 100% of the time, I don't need to read a "The Economist" article with a clickbaity, possibly misrepresented title of a nuanced meta-analysis.

The proof is on this comment, it's never enough data, the conclusion is always that you need more funding:

I didn't even need 1 subject, you need more than 360,000. You are out there running kubernetes for a blog and asking for more EC2 instances on top of a 3M$ bill, I'm out here running the whole company on 2 raspberry pis.

If wealth can be achieved by increasing resources or reducing necessities, I have achieved the nirvana of wisdom of the second kind while you still strive to amass more information to make a decision:

Yeah, I agree. This always seemed pretty obvious to me but it was also obvious that it's nuanced and can be highly variable depending on skin type, medical history, locale, lifestyle and preferences.

But when it comes to things which are very probably "mostly beneficial for most people most of the time - but (obviously) not always beneficial for all the people all the time", there's a reluctance to say anything unless you've got study data to fully support everything you say into "the nines". But the world is full of things that are hard, expensive or impossible to study experimentally with that kind of rigor.
