The investigations which have been carried on agree that environment is not so influential a cause for individual differences in intellect as is near ancestry. One rather interesting line of evidence can be quoted as an illustration. If individual differences in achievement are due largely to lack of training or to poor training, then to give the same amount and kind of training to all the individuals in a group should reduce the differences. If such practice does not reduce the differences, then it is not reasonable to suppose that the differences were caused in the first place by differences in training. As a matter of fact, equalizing training _increases_ the differences. The superior man becomes more superior, the inferior is left further behind than ever. A common occurrence in school administration bears out this conclusion reached by experimental means. The child who skips a grade is ready at the end of three years to skip again, and the child who fails a grade is likely at the end of three years to fail again. Though environment seems of little influence as compared with near ancestry in determining intellectual ability _per se_, yet it has considerable influence in determining the line along which this ability is to manifest itself. The fact that between 1840-44, 9.4 per cent of the college men went into teaching as a profession and 37.5 per cent into the ministry, while between 1890-94, 25.4 per cent chose the former and only 14 per cent the latter, can be accounted for only on the basis of environmental influence of some kind.[16] Another fact concerning the influence of environment is that it is very much more effective in influencing morality than intellect. Morality is the outcome of the proper direction of capacities and tendencies possessed by the individual, and therefore is extremely susceptible to environmental influences. We are all familiar with the differences in moral standards of different social groups. One boy may become a bully and another considerate of the rights of others, one learns to steal and another to be honest, one to lie and another to be truthful, because of the influence of their environments rather than on account of differences in their original natures. We are beginning to recognize the importance of environment in moral training in the provisions made to protect children from immoral influences, in the opportunities afforded for the right sort of recreation, and even in the removal of children from the custody of their parents when the environment is extremely unfavorable.
