VERIFICATION IN HUMAN SCIENCES Tentative generalizations must be valued merely as opinions until verification has been accomplished. Experiments on a small scale, carried out under trained leaders, on scientific plans, and prolonged for a sufficient time, under normal con- ditions and when real motives are operative, repeated again and again with uni- formly desirable results, will constitute a verification of plans for human welfare. These small-scale experiments should be planned on thorough studies of the situa- tions to be improved, and according to mental calculations on all the discoverable causal factors of human welfare. INTELLECTUAL IMMORALITIES (1) Carelessness in observations, "sloppy work." (2) Inaccuracy in determining units to be counted in statistical research. (3) Slovenliness in logic, fantastic explanations. (4) Generalizing beyond one's data. (5) Confusing opinions with knowledge. (6) Confidence in the results of research in disregard of weakness in proof and verification (7) Contentment with "discussion." (8) Poor judgment in research plan and procedure. (9) Wavering interest, fitting attention, attracted by peculiar superficialities. (10) Egoism allowed to crowd one to the invention of "new" theories for personal distinction. (11) Inventing interesting theories for the sake of selling them in books, articles, lectures and conversation. (12) Pride allowed to result in persistent belief in a theory for which one has been given credit. (13) Formulating an hypothesis on weak bases of facts, and then becoming blind to facts in opposition. (14) Emotionalism during research, "I believe" instead of "I have proved." (15) Adjusting theories to popular likes and dislikes. (16) Opposition to proof of another's theories because of jealousy. (17) Opposition to a theory merely because of ignorance and stupidity, "I can not see how." (18) Rushing into print with a report of research work that justifies no conclusions. (19) Degenerating into a propagandist of an unproved hypothesis, instead of being true to the research purpose of discovering the truth. (20) Cowardice in supporting a verified generalization because it is unpopular and conflicts with selfish interests. (21) Impatience, unwillingness to proceed step by step through a research. (22) Indulgence in dense verbiage for the sake of appearing superlearned. (23) Ignorance of the mechanism of instruments of precision, which results in their use when out of order. (24) Popularizing tentative generalizations for the sake of personal publicity. (25) Resort to the authorities, or to sarcasm and ridicule, against data, arguments and ver- ifications. Letters of advice are asked from all interested, especially covering ways and means for controlled experiments and other verifications in the human sciences.
