Jumping to conclusions (also called the JTC bias or inference-observation confusion) is a psychological term referring to the failure to distinguish between observation and inference. In other words, “when I fail to distinguish between what I observed first hand from what I have only inferred or assumed.”
Many flat Earth “facts” are simply the results of jumping to conclusions. They judged something without having all the facts, to reach unwarranted conclusions.
