What these paradoxical interpretations have in common is that they abandon realism, the doctrine that a physical world, existing in reality, accounts for all of our experience. Anti-realism remains popular and appears in various guises in textbooks and popular accounts of quantum theory.
而这类自相矛盾的解释的共同点就是都抛弃了现实主义，而现实主义这一基本信条认为存在于现实中的物理世界解释了我们的所有经验认识。当今量子理论中的反现实主义依然流行，并以各种面目跻身于教科书和流行解释之中。但爱因斯坦坚持物理现象必须可以用他所谓的“实体要素”来解释。
