Chapter 3  Reports, Inferences, Judgements Inferences The reader will find that practice in writing reports is a quick means of increasing his linguistic awareness. It is an exercise which will constantly provide him with his own examples of the principles of language and interpretation under discussion. The reports should be about first-hand experience-scenes the reader has witnessed himself, meetings and social events he has taken part in, people he knows well. They should be of such a nature that they can be verified and agreed upon. For the purpose of this exercise, inferences will be excluded.     Not that inferences are not important-we rely in everyday life and in science as much on inferences as on reports-in some areas of thought, for example, geology, paleontology, and nuclear physics, reports are the foundations, but inferences (and inferences upon inferences) are the main body of the science. An inference, as we shall use the term, is a statement about the unknown made on the basis of the known. We may infer from the material and cut of a woman's clothes her wealth or social position; we may infer from the character of the ruins the origin of the fire that destroyed the building; we may infer from a man's calloused hands the nature of his occupation; we may infer from a senator's vote on an armaments bill his attitude toward Russia; we may infer from the structure of the land the path of a prehistoric glacier; we may infer from a halo on an unexposed photographic plate that it has been in the vicinity of radioactive materials; we may infer from the sound of an engine the condition of its connecting rods. Inferences may be carelessly or carefully made. They may be made on the basis of a broad background of previous experience with the subject matter, or no experience at all. For example, the inferences a good mechanic can make about the internal condition of a motor by listening to it are often startlingly accurate, while the inferences made by an amateur (if he tries to make any) may be entirely wrong. But the common characteristic of inferences is that they are statements about matters which are not directly known, statements made on the basis of what has been observed.     The avoidance of inferences in our suggested practice in reportwriting requires that we make no guesses as to what is going on in other people's minds. When we say, "He was angry," we are not reporting; we are making an inference from such observable facts as the following: "He pounded his first on the table; he swore; he threw the telephone directory at his stenographer." In this particular example, the inference appears to be fairly safe; nevertheless, it is important to remember, especially for the purposes of training oneself, that it is an inference. Such expressions as "He thought a lot of himself," "He was scared of girls," "He has an inferiority complex," made on the basis of casual social observation, and "What Russia really wants to do is to establish a world communist dictatorship," made on the basis of casual newspaper reading, are highly inferential. We should keep in mind their inferential character and, in our suggested exercises, should substitute for them such statements as "He rarely spoke to subordinates in the plant," "I saw him at a party, and he never danced except when one of the girls asked him to," "He wouldn't apply for the scholarship although I believe he could have won it easily," and "The Russian delegation to the United Nations has asked for A, B, and C. Last year they voted against M and N, and voted for X and Y. On the basis of facts such as these, the newspaper I read makes the inference that what Russia really wants is to establish a world communist dictatorship. I agree."     In spite of the exercise of every caution in avoiding inferences and reporting only what is seen and experienced, we all remain prone to error, since the making of inferences is a quick, almost automatic process. We may watch a car weaving as it goes down the road and say, "Look at that drunken driver," although what we see is only the irregular motion of the car. The writer once saw a man leave a one-dollar tip at a lunch counter and hurry out. Just as the writer was wondering why anyone should leave so generous a tip in so modest an establishment, the waitress came, picked up the dollar, put it in the cash register as she punched up ninety cents, and put a dime in her pocket. In other words, the writer's description to himself of the event, "a one-dollar tip," turned out to be not a report but an inference.     All this is not to say that we should never make inferences. The inability to make inferences is itself a sign of mental disorder. For example, the speech therapist Laura L. Lee writes, "The aphasic [brain-damaged] adult with whom I worked had great difficulty in making inferences about a picture I showed her. She could tell me what was happening at the moment in the picture, but could not tell me what might have happened just before the picture or just afterward." 1  Hence the question is not whether or not we make inferences; the question is whether or not we are aware of the inferences we make. 1  "Brain Damage and the Process of Abstracting: A problem in Language Learning," ETC.: A Review of General Semantics, XVI (1959), 154-62.
