Oh, Death was never enemy of ours!
We laughed at him, we leagued with him, old chum.
No soldier’s paid to kick against His powers.
We laughed, -knowing that better men would come,
And greater wars: when each proud fighter brags
He wars on Death, for lives; not men, for flags.
Did the survey.
Results: I’m better at estimating continental populations than I had thought; I am frustrated by single-option questions in many cases (e.g. domain of study, nothing for significantly-reduced-meat-intake-but-not-strict-vegetarian, interdependent causes of global catastrophe) and questions that are too huge to be well-formulated, let alone reasonably answer (supernatural/simulation/God).
Also the question about aliens made me unaccountably sad: even if I retroactively adjust my estimates of intelligent alien life upwards (which I would never do), I have to face the incredibly low probability that they’re in the Milky way.
