It would seem that the
Polish Nationwide Research Group conducted research into Polish citizens' belief in "conspiracy theories" in late January 2021. The
original source appears to be behind a paywall (and it wouldn't take my credit card - I swear I'm not
that broke; I'll keep trying), but a couple of news articles in relatively reputable media have covered it as a story:
https://www.polsatnews.pl/wiadomosc/2021-02-26/11-proc-polakow-uwaza-ze-amerykanie-nie-wyladowali-na-ksiezycu-4-proc-ze-ziemia-jest-plaska/https://wiadomosci.radiozet.pl/Polska/Teorie-spiskowe-w-Polsce.-4-proc.-wierzy-ze-Ziemia-jest-plaska.-11-proc.-nie-wierzy-w-ladowanie-na-KsiezycuUnfortunately, I was unable to find anything in English, but Google Translate seems to spit out a pretty reasonable translation for these.
Based on these articles, it would seem that:
- 4% of Poles believe that the Earth is flat, significantly lagging behind the 11% of moon landing sceptics
- The belief is particularly popular in smaller cities and towns, at 5.6%
- The age group most likely to believe in a Flat Earth is around the age of 30, with just over 6% of believers
- 5% of Law and Justice (PiS) voters believe the Earth is flat, in stark contrast to 0% among Polish People's Party (PSL) voters. Similarly, PiS voters are much more likely to believe that the moon landing was a hoax, with those voting for the Left Together (Lewica Razem) being least likely to follow this belief.
According to both articles, this poll was performed on a sample size of 1001 Polish adults, which is pretty impressive for such a niche subject. I hope we can get to the original source to see if there's more detail to get out of it. If anyone has more luck with it than I did, help would be very much appreciated.
