In 1975 psychologist Lawrence Casler called for empirical research into the relative frequencies of career-appropriate names to establish if there is an effect at work or whether we are being "seduced by Lady Luck ". He proposed three possible explanations for nominative determinism: one's self-image and self-expectation being internally influenced by one's name; the name acting as a social stimulus, creating expectations in others that are then communicated to the individual; and genetics – attributes suited to a particular career being passed down the generations alongside the appropriate occupational surname. 
It is the common error of Socialists to overlook the natural indolence of mankind; their tendency to be passive, to be the slaves of habit, to persist indefinitely in a course once chosen. Let them once attain any state of existence which they consider tolerable, and the danger to be apprehended is that they will thenceforth stagnate; will not exert themselves to improve, and by letting their faculties rust, will lose even the energy required to preserve them from deterioration. Competition may not be the best conceivable stimulus, but it is at present a necessary one, and no one can foresee the time when it will not be indispensable to progress.
