美國心理學家巴南佛瑞(Bertram Forer)於1984年給所有學生做了一項人格測驗，然後根據測試結果分析該學生的人格特徵。
佛瑞的研究表明:人們常常認為，一種籠統的、一般性的人格描述十分準確地揭露了自己的特點，當人們用一些普通的、含糊不清的、空泛的形容詞來描述一個人的時候，人們往往很容易就接受了這些描述，而認為描述中所說的就是自己
你祈求受到他人喜愛，卻對自己吹毛求疵。雖然人格有些缺陷，但大體而言，你都有辦法彌補。你擁有可觀的未開發潛能，但尚未發揮出自己的長處。看似強硬、嚴格自律的外在掩蓋著不安與憂慮的內心。許多時候，你嚴重質疑自己是否做了對的事情或正確的決定。你喜歡一定程度的變動，並在受限時感到不滿。你為自己是獨立思考者而自豪，並且不會接受沒有充分證據的言論。但你認為，對他人過度坦率是不明智的。有些時候，你外向、親和、善於交際，有些時候你卻內向，謹慎而沉默。你的一些抱負是不切實際的。
