psychology is presented with its invaluable aid in judg¬
ing the reliability of testimony. The psychotechnics of
science and industry are set forth with an account of the
problems and experiments to which the psychologist had

not but profit from a knowledge of psychotechnics and
from its application to his work is—the psychologist him¬

Among them were the paper on Beulah Miller in the
Metropolitan Magazine, and an article called “ Naïve

naïve psychology of the amateur, when our world is so
full of social problems which will be solved only if the
aptitudes and the workings of the mind are clearly recog-
