plenty of explanations for this map: cultural differences in how phenomena are interpreted (what americans interpret as 'aliens' may be more likely to be interpreted as 'angels' or 'spirits' or 'weird imperialist jets' or something in many other cultures without the same mass media sci fi trends in their pop culture, and maybe they are even correct to do so!), less access to electronics like cameras to record sightings, less interest among media industries of other cultures to cover such topics, less military equipment like radars and jets deployed to possibly detect phenomena, less organizations researching sightings in other countries, etc. Its silly to present this one map as some kind of 'gotcha' imo.
To add on to your first point there: There are some notions that have been put forth that suggest the UFO phenomenon is, for lack of a better term, partially psychic in nature. The idea is that whatever this is, it is something that appears to be whatever one expects it to be. Not in the sense that the phenomenon is experienced solely through a cultural lens, but that there are aspects to it that cannot be fully perceived through the human senses and thus the pattern-seeking mind fills in the blanks. The theory posits that of the slim percentage of UFO sightings that are "real" were observations of something that exists in more dimensions than just three.
I am perfectly mentally healthy and only have normal thoughts.
you're an alien. you're visiting one of the zoos. where are you spending your time? the regular people doing normal shit or the cognitively impaired albinos shooting each other and ramming each other in their little conveyances.
only reports made to an English language org based in the US. I wish people would stop posting this misleading shit, I used to think it was funny too until I learned it's meaningless and misleading and doesn't prove anything.
