You have a great need for other people to like and admire you. You have a tendency to be critical of yourself. You have a great deal of unused capacity which you have not turned to your advantage. While you have some personality weaknesses, you are generally able to compensate for them. Your sexual adjustment has presented problems for you. Disciplined and self-controlled outside, you tend to be worrisome and insecure 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 pride yourself as an independent thinker and do not accept others’ statements without satisfactory proof. You have found it unwise to be too frank in revealing yourself to others. At times you are extroverted, affable, sociable, while at other times you are introverted, wary, reserved. Some of your aspirations tend to be pretty unrealistic. Security is one of your major goals in life.
MindHacks describes the classic study (Hat tip: Cheap Talk):
Psychologist Bertram Forer gave a personality test to his students and then asked each person to rate how the accuracy of their 'individual personality profile'. In reality, all the 'individual profiles' were identical but students tended to rate the descriptions as highly accurate. In fact, on a scale of 1-5, students rated the accuracy of their profile, on average, as 4.2.
This brings to mind the difficulty of knowing oneself, which has been a topic I've been thinking a lot about since Robert's post on his philosophy of identity. I hope to write more on this soon.
