AI评估需从只看行为转向关注内在机制,否则难辨真智能
Beyond Behavior: Why AI Evaluation Needs a Cognitive Revolution
- 主张突破仅靠行为判断智能的旧范式
- 指出当前评估无法区分不同计算过程产生的相同输出
- 适合关注AI本质与可解释性的研究者阅读
1950年,图灵提出用行为测试替代‘机器能否思考’的问题:若机器输出与人类不可区分,即可搁置其是否真正思考的争议。本文认为,图灵此举不仅是实用简化,更是一种认识论承诺——即何种证据才可作为智能归属的依据,这种承诺已悄然约束了人工智能研究七十年。我们追溯这一行为主义认识论如何嵌入评估体系,使关于过程、机制和内部结构的一类问题被长期回避,如同心理学从行为主义转向认知主义前的困境。当前AI评估仍局限于行为表现,无法区分不同计算路径实现相同结果的系统,而这正是智能判断的关键。因此,领域需要一场类似认知革命的范式转变:不放弃行为证据,但必须承认其不足以支撑智能建构主张。本文阐明后行为主义认识论应有之义,并提出当前无法提出却亟需探讨的新问题。
原文摘要 · Abstract (English)
In 1950, Alan Turing proposed replacing the question "Can machines think?" with a behavioral test: if a machine's outputs are indistinguishable from those of a thinking being, the question of whether it truly thinks can be set aside. This paper argues that Turing's move was not only a pragmatic simplification but also an epistemological commitment, a decision about what kind of evidence counts as relevant to intelligence attribution, and that this commitment has quietly constrained AI research for seven decades. We trace how Turing's behavioral epistemology became embedded in the field's evaluative infrastructure, rendering unaskable a class of questions about process, mechanism, and internal organization that cognitive psychology, neuroscience, and related disciplines learned to ask. We draw a structural parallel to the behaviorist-to-cognitivist transition in psychology: just as psychology's commitment to studying only observable behavior prevented it from asking productive questions about internal mental processes until that commitment was abandoned, AI's commitment to behavioral evaluation prevents it from distinguishing between systems that achieve identical outputs through fundamentally different computational processes, a distinction on which intelligence attribution depends. We argue that the field requires an epistemological transition comparable to the cognitive revolution: not an abandonment of behavioral evidence, but a recognition that behavioral evidence alone is insufficient for the construct claims the field wishes to make. We articulate what a post-behaviorist epistemology for AI would involve and identify the specific questions it would make askable that the field currently has no way to ask.
