Candidates were given continuous psychiatric interviews throughout the week, and extensive self-examination through a battery of 13 psychological tests for personality and motivation, and another dozen different tests on intellectual functions and special aptitudes–these were all part of the Week of Truth at Dayton.

Two of the more interesting personality and motivation studies seemed like parlor games at first, until it became evident how profound an exercise in Socratic introspection was implied by conscientious answers to the test questions “Who am I?” and “Whom would you assign to the mission if you could not go yourself?” In the first case, by requiring the subject to write down 20 definitional identifications of himself, ranked in order of significance, and interpreted protectively, the psychologists elicited information on identity and perception of social roles. In the peer ratings, each candidate was asked which of the other members of the group of five accompanying him through this phase of the program he liked best, which one he would like to accompany him on a two-man mission, and whom he would substitute for himself. Candidates who had proceeded this far in the selection process all agreed with one who complained, “Nothing is sacred any more.”
