Besides saying that I have taken the survey...

I would also like to mention that the predictions of probabilities of unobservable concepts was the hardest one for me. Of course, there are some in which i believe more than in some others, but still, any probability besides 0% or 100% seems really strange for me. For something like being in a simulation, if I would believe it but have some doubts, saying 99%, or if I would not believe but being open to it and saying 1%, these seem so arbitrary and odd for me. 1% is really huge in the scope of very probable or very improbable concepts which cannot be tested yet (and some may never ever be).

... before losing my sanity in trying to choose the percentages I would find plausible at least a few minutes later, I had to fill them based on my current gut feelings instead of Fermi estimation-like calculations.
