叙述可靠性侧重具体的文本策略，文学真实性侧重总体的呈现效果。就修辞学路径而言，叙述可靠性通过叙述者体现出隐含作者的修辞策略，让文学真实性在叙述层面获得保障；就认知学路径而言，叙述可靠性有赖于读者的视角机制，文学真实性是读者形成视角机制的潜在基础。如果考虑真实作者的因素，依靠隐含作者修辞或读者认知的叙述可靠性又会出现新的情况，这些新情况导致文学真实性的多样化。由于叙述可靠性和文学真实性的着眼点不同，叙述可靠性与文学真实性之间呈现出复杂的关系：或者是叙述可靠但给人感觉不真实，或者叙述不可靠但给人感觉真实。此外，随着接受语境的变化，叙述可靠性和文学真实性自身也会发生变化。

Narrative reliability focuses on specific textual strategies, while literary authenticity highlights the overall effect of presentation. In terms of rhetoric, the former reflects the rhetorical strategy of the implied author through the narrator, so that the latter can be guaranteed on the narrative level. In terms of cognition, narrative reliability relies on the reader's perspective mechanism, for which literary authenticity serves as the potential basis. Considering the factor of the real author, new situations regarding the narrative reliability of the implicit author's rhetoric and the reader's cognition will arise, which leads to the diversification of literary authenticity. Given that the focus of narrative reliability and that of literary authenticity differ, a complexity between narrative reliability and literary authenticity emerges: the narration is either reliable but unrealistic, or unreliable but realistic. On top of that, narrative reliability and literary authenticity are subject to the change of receptive context.
