Researchers in the UK did a longitudinal study on 174 subjects measured first at age 14 and then at age 77. They were rated on six personality characteristics related to dependability. At age 14, they were rated by teachers; at age 77, they rated themselves and were rated by a close relative or friend. The ratings at 14 and 77 showed no relationship. The study had many flaws, like the different raters, but, nevertheless, called into question the stability of dependability over time. (Mayer, M. W. Once dependable, always dependable?
