In his original study, Forer gave subjects a personality analysis followed by the following 'result':
"You have a need for other people to like and admire you, and yet you tend to be critical of yourself. While you have some personality weaknesses you are generally able to compensate for them. You have considerable unused capacity that you have not turned to your advantage. Disciplined and self-controlled on the outside, you tend to be worrisome and insecure on the inside. At times you have serious doubts as to whether you have made the right decision or done the right thing. You prefer a certain amount of change and variety and become dissatisfied when hemmed in by restrictions and limitations. You also pride yourself as an independent thinker; and do not accept others' statements without satisfactory proof. But you have found it unwise to be too frank in revealing yourself to others. At times you are extroverted, affable, and sociable, while at other times you are introverted, wary, and reserved. Some of your aspirations tend to be rather unrealistic."
Yeah, you and everyone else in the world... and so on average, Forer's subjects found the above description pretty accurate.
But think about it, even if you are 'one in a million' that means there are 6000 people just like you. I honestly believe that one of the functions of scripture is to remind us that we are not unique. We all exist in a common human condition. That's how scriptures "work". That's how texts written over a thousand years ago in a distant land can still ring true... in spite of the printing press and the internet and indoor plumbing and nuclear power and digital watches, people are still people. But more on that later.
