Went in and did it again, because I forgot to note my score last time (2.7666).
Really so many of these questions are meaningless, in today's world, or have different meanings than that intended at the time. In this time of bird flu and SARS, the 'people move around so much we must protect ourselves" statement is perfectly reasonable, of course we must. I strongly suspect, though, that this was not the original meaning of the question, that this is 'code' for racial purity.
"Wars and social troubles may someday be ended by an earthquake or flood that will destroy the whole world." Again, I have no trouble answering 'strongly agree' to this statement. Because of the use of the word 'may', anyone would have to agree with it. I think though, that there is some subtext of 'therefore, we don't have to do anything about these troubles' and possibly some 'just vengeance of an angry God' going on there too.
I think that if I had answered the statements according to what the subtext was going for, rather than the face value, I would be more than an airhead, I would be the snivellingest of wimps!
