In a word.. NO. They can never admit when they have been WRONG.when time proves them wrong they cover it over with some shuffle speech. (Take the 1975 fiasco of people selling up and being applauded for it)
What pushed them all the years to make all the predictions? Only their own ego and a desire to 'look into things' but coming from their occult background pyramidology, wings of Horus on a publication and a few kh etc, isnt surprising.
and they have never been able to see that all the worlds peoples are not urban living Americans. One size does not fit all.
