Summary: This case illustrates the fact that pathological lying and accusation may arise first during a period of special stress. A young woman of 19, after illegitimately becoming pregnant, was found home after home by a charitable organization. In each place she made false accusations of immoral proposals against some one in the family or neighborhood. This created much trouble and lost her several good homes. Her lies persisted after an abortion had been secretly produced, but it is to be noted that she now, as a sequel to the operation, suffered from irritative pelvic conditions. A short statement of this case will suffice to bring out the point that during a period of social and mental upset pathological lying and accusation may be first indulged in. We studied the case of a young woman of 19 who had been the source of much trouble in a certain locality on account of her false accusations. She was taken in hand by a charitable organization and found a home, after she had become pregnant at a wedding feast where alcoholic stimulants flowed freely. There was then no one to look after her but an invalid father. She was placed with an estimable family. In a short time she made the shocking announcement to the wife, and to others, that the husband had made immoral advances to her. He was a man of excellent character and of course this could not be believed. She was then placed on a farm, where she showed erotic tendencies and insisted that one of the helpers about the place wanted to take liberties with her. She was observed flirting and making advances to thrashers and others. She had to be found a new home, and this time it was in a city, where new accusations were made against a delivery boy. After this the young woman made off and shifted for herself for a time, and succeeded in getting some shady character to produce an abortion on her. Later, she again came to the official attention of the social agency by reason of making new accusations. From the date of her impregnation to the time we first studied her, a period of about 10 months, she had made serious accusations against many. When her lies were told in a new environment they, of course, always made new trouble. Each time, however, the girl herself was the loser. Her real partner at the wedding feast had early deposited several hundred dollars for the expected infant. We found a strong, normally developed young woman of rather attractive appearance for the grade in society from which she came. No sensory defect. Diseased tonsils. Complained of constant suffering from pelvic conditions, perhaps induced by the abortion. However, being such a strong type she has been able to get about well and do her daily work. When we saw her she was employed in a factory.
