Separately, to answer your question… It’s generally been assumed I suppose, if a product is invented and people use it, that means it’s providing some positive impact. Like asbestos did initially.

What this research says is that there are products that make the users’ lives worse, and would be even worse than that if they didn’t because their peers are using the products and they would be left out.

Like, the ideal scenario for happiness might be if Tiktok didn’t exist, but since it does it’s now a choice for school aged kids between “using Tiktok and absorbing harmful messages” and “not using Tiktok and feeling left out and possibly being ostracized by their peers”. The very existence of some products cause usage simply because it’s the least bad option of using/not using.

Asbestos is strong, cheap, has great fire insulation, sound insulation, heating insulation, fire protection, and resistant to water. What a wonderful building material! It wasn’t until later that we discovered the health hazards (or, maybe they were known but it only became widely and publicly known later, I’m not sure).

It works very well in my brake system.
