It applies equally to traditional historians who view history as only the external and internal criticism of sources, and to social science historians who equate their activity with specific techniques.

译：这种谬误同样存在于历史传统家和历史社科家;前者认为历史仅仅是史学界内部和外部人士对各种史料来源的评论，后者则认为历史的研究是具体方法。

1. it 所指代的内容，需要联系上文方能做出判断。因此，联系昨天的句子，it指代the technical fallacy, 即：(纯)技术错误。

2. 句子主干为it /applies to /traditional historians and to social science historians，其中，apply to 表“与……相关/存在于……”

3. who view history as only the external and internal criticism of sources和who equate their activity with specific techniques为定语从句，分别修饰traditional historians和social science historians。由于定语从句较长，建议处理为单句。

4. activity一词在本句中译为活动不妥，“历史学家的活动”显然表意模糊，译为“历史学家的研究”更为恰当。
