胡贝尔认为根据贝叶斯理论可推出证据的可靠性与认证度呈反比关系,这种有违直觉的关系构成了对贝叶斯认证逻辑的责难,而旧证据问题则是这种不统一的反比关系更深刻的描述。证据的可靠性与认证度的反比关系并不是贝叶斯认证理论和科学实践的分歧,恰恰相反,贝叶斯认证理论如实地反映了科学家的实际行为。不仅如此,贝叶斯认证理论表明,证据对假说的支持关系并不是单一静态的,而是复合多元的,并且呈现出动态的发展图景。
鬍貝爾認為根據貝葉斯理論可推齣證據的可靠性與認證度呈反比關繫,這種有違直覺的關繫構成瞭對貝葉斯認證邏輯的責難,而舊證據問題則是這種不統一的反比關繫更深刻的描述。證據的可靠性與認證度的反比關繫併不是貝葉斯認證理論和科學實踐的分歧,恰恰相反,貝葉斯認證理論如實地反映瞭科學傢的實際行為。不僅如此,貝葉斯認證理論錶明,證據對假說的支持關繫併不是單一靜態的,而是複閤多元的,併且呈現齣動態的髮展圖景。

Huber holds the tough statement that the more reliable the evidence is,the less supportive it can provide,in the view of the Bayesian confirmation.It seems that the counterintuitive fact is a big challenge for the Bayesian confirmation,and the old evidence problem aggravates the situation.How-ever,the paper shows that the inverse relationship between the reliability of evidence and conforma-tion has never been a conflict between the Bayesian confirmation theory and the actual scientific prac-tice,but an exact description of the actual behavior of the scientists.Moreover,the Bayesian method-ology shows that the support from the evidence to hypothesis is never static but complicated and multi-variate,and presents a dynamic developing feature.
