I've always thought the Overview Effect is a cognitive error, but it has this cloud of piety surrounding it "because astronauts".
At its best, it inspires calls to environmentalism (the fragility of the Earth), but at its worst, and it's usually at its worst, it inspires nihilistic Carl Saganisms like the Pale Blue Dot.
I mean it is a bit nihilist but again just calling something nihilist doesn't invalidate it. I agree The way he[Carl Sagan] weighs it is the way that I think people should view this idea. Instead of taking it to believe nothing matters, take it as a means to strive to do better, to see the only barriers that prevent our civilization from accomplishing greatness are artificial.
Because you could insert any other human concern into those enumerated in "Pale Blue Dot", and they become just as easily diminished. Like human rights, for instance. Who cares about female genital mutilation - after all, Betelgeuse is huge, man! Who cares about something as small as a clitoris?
See, I have always considered that it had the opposite effect - by looking at the big picture, putting things in perspective and calling for a more humanistic outlook on life, it inspires empathy and action towards "making the world a better place". Far from trivializing widespread issues such as the ones you pointed out.
But then again, you already acknowledged this out in your previous comment, and I get that here you were just trying to explain what you thought the alternative was.
This is how I take it too. Sagan isn't saying that all human problems are insignificant or unimportant, but it's entirely true that many of the things we fight over and even kill each other over are, when put into perspective, pretty stupid. The whole point is to take a step back and carefully evaluate things as a first course of action and to try to save conflict and aggression for situations where it's meaningful and likely to make a positive impact in the bigger picture.
I agree with other commenter that the overview effect is real but an error. Just because earth is smaller than Saturn doesn't make it insignificant, or make our concerns - wars, religions, reality TV and all - petty. There is absolutely nothing of significance in Saturn that compares to what we have on earth. Significance can't even exist without life.
The thrust of Sagan's monologue was to encourage re-evaluation of religiously-motivated anthropocentrism.
To me, at least, it's less of "how could anything here matter when Saturn is so big?" and more of "does it really seem plausible that this vast universe was created for the benefit of some creatures on the surface of this little speck? Do you really think we're that special?"
Certainly it's possible to ride the Overview Effect all the way to nihilism, but it seems clear to me that unexamined anthropocentrism is at least as incorrect.
I understand what point you are trying to make, but it's hardly a fitting analogy, and I don't think it's a fair point.
One is a short-lasting altered state of consciousness.
The other is an idea, a change of perspective that can inspire action and positive lifestyle change. Or perhaps a descent into nihilism, depending on circumstance.
Most critical? Maybe not. But it is undoubtedly very much a significant and underrecognized factor.
