Would they stay away?

The imagined visitor

Suppose another civilisation could examine humanity in enough detail to form an opinion. That premise is fiction for this essay, not a report that anybody is watching. What might make a meeting seem inadvisable?

One answer is our uneven relationship with power. We can build astonishing tools and argue endlessly about who should control them. We can recognise a danger and still reward the behaviour that produces it. An observer might find the engineering impressive and the governance rather unfinished.

Which Earth would they see?

A civilisation is not a single personality. A photograph of a war is real and incomplete. So is a photograph of strangers sharing food after a disaster. A visitor who selected only our worst acts would produce an indictment, not a full portrait.

Our own journalism offers a warning here. Dramatic events travel quickly. Patient maintenance, care and prevention often attract less attention precisely because they stop a catastrophe from becoming a headline. An outsider could mistake visibility for prevalence, just as we do.

Then there is the visitor’s character. We cannot assume that advanced technology produces compassion, curiosity or even an interest in conversation. The thought experiment becomes more honest when their motives remain a question.

The mirror under the telescope

The exercise is useful because it asks what kind of invitation we are already making to one another. A society that treats disagreement as an enemy to destroy is a difficult host even before anybody arrives from the stars.

Would they stay away? We cannot supply an alien answer. We can examine the human one: what would make this planet easier to approach with trust?

Perhaps the best improvement to Earth’s hypothetical travel review is ordinary and demanding: fewer reasons to fear its inhabitants, and more reasons to believe that its remarkable abilities can be used with care.
