How did they ask people to locate Ukraine? Some of these points look like somebody accidentally clicked on a random spot of a map. For example, the dot below New Zealand is in the middle of the ocean (approx. -55.000000,176.000000). Some even located it within the US (Florida seems to be a popular guess). Have they found really misinformed people or is this noise in the data?
I wonder if that is from a side-scrolling artifact or drag/drop interface in the sampling (wild speculation there) or from an unconscious pruning algorithm, among people who are unaware of Ukraine's proximity to the Black Sea, roughly: "hmmh, Ukraine, medium-to-small country, former Soviet, I'll look further east, oops, there's China, better stop here.
Some more informative maps include languages and hydrocarbon pipelines:
