We are concerned here not with inference from physiognomic features and anthropometric measurements, but with impressions based on the observed conduct, expression and achievement of the individual who is in question, his or her characteristic behavior, attitudes, activities, reactions, and accomplishments. When the individual being judged is a total stranger and the judgment is immediate, estimates of character are of course merely of the type discussed in preceding sections on phrenology and physiognomy.
Professor Cattell once requested twelve acquaintances of five scientific men to grade these five men in the various traits of character to which we have referred on page 127. The grades assigned were to represent the position of the individual in his group. Thus a grade of twenty-five per cent would mean that the individual belonged in the lowest one-quarter of the total group of scientific men in the country, in the trait so marked, three-fourths of the group being superior to him in this trait. A grade of one hundred per cent would mean that the individual so graded would belong among the highest one per cent of all the scientific men in the country, in the trait so marked. When these records were compiled it was seen that in the case of certain traits, such as energy, perseverance, efficiency, the twelve judges differed much less among themselves than when judging other traits, such as cheerfulness, kindliness, unselfishness. It is interesting to note that the traits on which the judges agreed closely represent the individual's reactions to objective things, whereas the traits on which they disagreed most represent the individual's reactions toward other people.
There are, of course, several reasons for this result. In the first place the reactions of an individual to objects, as displayed in his daily work, are matters of common knowledge and are likely to leave objective and even measurable evidence such as wealth, books, buildings, etc. Reactions to other individuals are more likely to vary with the occasion and with the companion, and are also likely to be deliberately controlled, inhibited or assumed, in the interest of more objective and remote ends. This would mean that whereas in the first case all the judges were dealing with much the same material, in the form of actual products of the traits in question, in the second case they were more or less likely to have in mind rather different reactions or occasions of a more strictly personal character.
