TL;DR – Since the standard for evidence is so high when it comes to looking for extraterrestrial life there’s a heightened chance of false negatives.
Thought that was kinda already understood by most scientifically literate people.
So I wasted all that precious SETI@Home computing time back in the 90s for nothing??

The standard of evidence is high because the alternative, false positives, is even worse.
Very weird position to take. Current missions have not really made any strong negative claims, so they can not have had significant false negatives either. Basically just because Percy and Curi have not detected life doesn’t mean that science community is claiming that the non-existence of life on Mars has been proven.

> Space missions and instruments are designed to detect potential signs of life, but the risk of overlooking something is not taken into account
really? I’d think the scientist are pretty damn well aware of the limitations of the current mission instruments and our (lack of) capability to detect life.
> So, investigate thoroughly whether the conditions for the existence of life forms are present in the environment, and whether you can recognise patterns on the surface of a celestial body
I bet any planetary scientist would love to get some subsurface sampling/measurement capability. But there are limits on engineering on what we can do
> But if we do not investigate this further, it could indeed result in a false negative
That is not what false negative means. It would just result it being unknown, not false negative. The key distinction being that *unknown is not negative*.
How about you look at our planet lmao. There’s life here and it’s everywhere. Literally impossible to go anywhere without it on earth. And I mean anywhere.
Of course it’s flawed. Could you imagine a totally perfect search for life? That’s not what’s happening
I’ve always thought it was improbable anyway because of the way space time works. Any aliens looking at earth, are looking at earth as it was way in the past, way before humans. So they won’t even notice us . Maybe they just see dinosaurs. Maybe the earth is still brand new and barren.
Similarly, when we look into space we are looking into the past, so it’s possible that we’re looking at planets where alien lifeforms have already left, gone extinct, or maybe they simply haven’t even arrived yet.
