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. [4] loc. cit. [5] Vide p. 140, in chapter on Statistics, William Healy, ``The Individual Delinquent.'' Little, Brown, and Co. Boston, 1915. 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.
