Pathology of Lying, accusation, and swindling: a study in forensic psychology

The important part which behavior of this type sometimes plays in court work is witnessed to by the records of our own cases as well as those cited in the previous literature. The legal issues presented by pathological lying may be exceedingly costly. These facts make it important that the well-equipped lawyer, as well as the student of abnormal psychology, be familiar with the specific, related facts. For such students the cardinal point of recognition of this class of conduct may at once be stated to be its apparent baselessness.

The only method by which good understanding may be obtained of the types of personality and mentality involved in pathological lying, accusation, and swindling, as well as of the genetics of these tendencies, is by the detailed reading of typical case histories. In this fact is found the reason for the presentation of this monograph. Appreciation of the nature of the phenomena can only be obtained through acquaintance with an entire career. Any of us may be confronted by fabrications so consistent as to leave at one or several interviews the impression of truth.

Our selection of literature to summarize needs no explanation. We have simply taken all that we could find which specifically bears on the problem. Lying, in general, especially as a form of delinquency, has received attention at the hands of some authors, notably Ferriani[1] and Duprat.[2] The falsifications and phantasies of children and adolescents have been dealt with by Stanley Hall.[3] None of these goes into the important, narrower field with which we are here concerned. The foreign literature is vitally important in its opening up of the subject, but from the standpoint of modern psychopathology it does not adequately cover the ground.

The fabrications, often quite clever, of the clearly insane, which in earlier literature are confounded with pathological lying, we have discriminated against as not being profitable for us to discuss here, while not denying, however, the possibility in some instances of lies coexisting with actual delusions. We well remember a patient, a brilliant conversationalist and letter writer, but an absolutely frank case of paranoia, whom we had not seen for a period during which she had concocted a new set of notions involving even her own claim to royal blood, confronting us with a merry, significant smile and the remark, ''You don't believe my new stories, do you?''

A short statement on the relation of lying to delinquency may be of interest here. Ferriani's discussion[4] of the lying of 500 condemned juvenile offenders, with classification of their lies, ranging from self-defense, weakness, and fancy, to nobility of purpose, does not include our field. Nor does he leave much room for appreciation of the fact we very definitely have observed, namely, that plenty of young offenders are robust speakers of the truth. Our analysis[5] of the delinquencies of 1000 young repeated offenders carefully studied by us does not tell the proportion of truth tellers as distinguished from liars, but it does give the number in which lying was a notable and excessive trait. The total number of males studied was 694, of females 306. Ages ranged from 6 to 22; average about 16 years.

MALES FEMALES

Lying--counted only when excessive and a 104 80 notorious characteristic of the individual, (15%) (26%)

False accusations--only recorded when of an 5 16 excessive and dangerous sort, (.7%) (5%)

The exact number of pathological liars is not determinable in our series because of the shading of this lying into other types. It would be safe to say that 8 or 10 of the 1000 were genuine cases of pathological lying according to our definition, that 5 more engaged in pathological false accusations without a notorious career in other kinds of lying. Examples of borderline mental cases showing fantastic lying and accusations are given in our special chapter. Some of the cases of pathological lying given in this work do not belong to the series of 1000 cases analyzed for statistical purposes. The extraordinary number of times several of these individuals appeared in court (resembling in this respect the European case histories) shows that the total amount of trouble caused by this class is not in the least represented by their numerical proportion among offenders.
