Optimism isn’t gullibility!

It is just an attitude that values positive possibilities over fretting about negative possibilities.

Especially in cases where there is a small chance of a huge upside, relative to virtually no downside. We didn’t lose any superconductors. :)

I don’t recall anyone on HN erroneously declaring the material was definitely a new superconductor before subsequent evidence arrived at a consistent conclusion.

There is nothing wrong with optimism.

Perhaps you misunderstood?

To clarify, I was referring to "An optimistic outlook" in terms of actual assertions/claims/etc. that are written down on-the-record in public.

Of course HN users can have the general abstract sentiment of optimism at anytime in their mind. I don't think there are any norms around internal sentiments.
