How does the Chinese room argument challenge the Turing test?

The Chinese room argument, developed by American philosopher John Searle, challenges the Turing test by arguing that the simulation of intelligence is not equivalent to genuine understanding.12

The Turing test posits that if a machine can interact with a human interrogator such that its responses are indistinguishable from those of a human, it can be considered intelligent. Searle’s thought experiment counters this by describing a person who uses a manual to manipulate Chinese symbols to produce correct responses to questions in Chinese, despite having no actual knowledge of the language.132

Searle argues that because the person—acting as a computer program—produces perfect outputs through mere syntactic symbol manipulation without understanding the semantic meaning of the symbols, the machine similarly fails to exhibit true thought or intelligence. Consequently, Searle asserts that the Turing test is an insufficient criterion for intelligence, as it relies on external performance rather than the internal mental states required for genuine comprehension.12
