Do Finns really navigate better than all the rest of the nations? I have just read Evolutionistx's recent blog post on a ranked list of the spatial navigation ability of people. The test that involved more than 2.5 million people has been done with the help of some purpose-developed computer games. And it says the 5 distinct clusters they got for results depend on both the wealth of those people (GDP per capita), as well as on gender inequalities (Gender Gap Index). Is that really the reason behind these findings? And where are all the African countries (except South Africa)? You can check out the full study here.
