What's hilarious is the astrology nutters that claim to predict personalities for people in the past like Hitler, Saddam Hussein, Princess Diana and the like -or well-known personalities of the present like Bush, Donald Trump and Paris Hilton. What these frauds are doing is using data to create the test rather than the test to produce the data. Anyone willing to outright lie or steal or deluded enough to have a difficult grasp on reality can do this.
Can you explain what you mean by 'use data to create the test'?
