There are very good reasons, which anyone smart and open-minded can find out, to think that Covid didn’t come from the Institute. So why should we care about this news?
Lots of uncurious people don't care about understanding the world around them. This story probably isn't for them, and I'm certainly not here to try to change those kinds of attitudes.
That was not your question, you asked about "we" not curious people. For the latter, there is no should about it, they just do. That is the nature of curiosity.
