Geographical tendencies to exaggerate research claims

Are there any particular areas on the globe that automatically raise eyebrows when claims are made regarding research or performance that seem to good to be true?

    I have a lot of internet friends from eastern European countries whose work I admire very much, but it has gotten to the point I feel like I want to challenge every claim they make as I have often found myself years ahead of them in the same type of work they are doing and I know for a fact what they are doing will not perform as they claim it does. It bothers me because in most cases these guys are intelligent, and highly skilled. It makes me think the need for validation will simply drive them to cheat. It seems like a cultural thing? I hope I don't get jumped on too bad for saying this but it happens so often I can't help but feel this way.
