This may or may not be history-related (depends on the answer, I suppose). I just saw this chart someone tweeted, charting how different each country is culturally from the US. Egypt and Yemen are the two most different from us. Anyone know why? I would have thought the asian collectivist cultures or Iraq/Iran/palestine would be the most different.

Differences studied include "politics, like attitudes toward democracy; social relationships, like how to raise children; religious norms and traditions; and attitudes toward sex, finances, law, environment, science and innovation, arts and creativity, sports and recreation, the media, and consumerism."

Hi there! While your question doesn't break any rules per se, be aware that as currently phrased it is highly unlikely to get a satisfactory response. What you are asking for is an unbounded, three-way comparative history between three (very) separate states - not only is any given user unlikely to have particular expertise in the histories of two of these states, any one of these might be a book in its own right:
politics, like attitudes toward democracy; social relationships, like how to raise children; religious norms and traditions; and attitudes toward sex, finances, law, environment, science and innovation, arts and creativity, sports and recreation, the media, and consumerism.
Simply put, asking more focused questions that don't ask for direct comparisons are more likely to succeed. You are welcome to ask more than one such question if you wish.
