"Transductive reasoning" refers to a type of thinking commonly identified in young children. Transductive reasoning is based on concrete instances rather than inductive or deductive reasoning.
With transductive reasoning, a child reasons from case to case, ignoring important, well-established facts they have yet to learn. For example, a child might reason that pizza is triangular in shape rather than round, if they have only seen single slices. Also, a child might reach the conclusion that he is capable of turning into an Asian if he eats rice, because his friend Larry, who eats rice regularly, is Asian. Both of these cases exemplify the use of transductive reasoning.
