Inference: The Process
Inference is a mental process by which we reach a conclusion based on specific evidence. Inferences are the stock and trade of detectives examining clues, of doctors diagnosing diseases, and of car mechanics repairing engine problems. We infer motives, purpose, and intentions.
Inference is essential to, and part of, being human. We engage in inference every day. We interpret actions to be examples of behavior characteristics, intents, or expressions of particular feelings. We infer it is raining when we see someone with an open umbrella. We infer people are thirsty if they ask for a glass of water. We infer that evidence in a text is authoritative when it is attributed to a scholar in the field.
