Inference inference, drawing a conclusion from what you already know or observe, is how we move from one idea to the next. You see smoke. You infer fire. You hear a voice behind the door. You infer that someone is there. You do not see the fire or the person. You conclude they are there from the signs. First, you have a sign—smoke, a sound, a footprint. Then you connect it to something else—fire, a person, a passing animal. That connection is inference. It can be strong or weak. Strong when the sign almost always goes with the conclusion. Weak when it might be a coincidence. Learning to tell the difference is part of thinking well. Inference can go wrong. Sometimes we jump to a conclusion too fast. Sometimes we ignore signs that point the other way. So checking our inferences—asking "What else could explain this?"—is a habit that protects us from error. When we share our reasoning with others, they can point out what we missed. That is why inference, like observation, belongs in a community. We infer together, and we correct each other. What is one thing you inferred today? Was there another possible explanation?
