Step-by-step explanation:
In Piaget's terms, a person who argues only from 'personal experience' and refuses to use any other evidence is likely displaying egocentrism. Egocentrism is a cognitive bias characterized by the inability to consider or understand other perspectives, leading to a limited understanding of the world. When someone relies solely on their personal experience without considering other evidence, they are unable to engage in abstract thinking and fail to recognize the limitations of their own viewpoint.
