例如，传记作家很难超越自己的先入之见，成为真正的目标。传记应该作为来源，但要记住，传记往往是主观的，而不是总是客观地写出来的。使用传记的优势之一是直接聚焦于某一事件，传记作者可能会比一般的历史书更深入、更详细地描述事件，也许会给人一种人性的倾向。传记作者可能会有偏见，他们有时会说自己爱上了他们的对象。虽然这可能有点夸张，但事实是，很难客观地描述一个作者在深度分析和感觉理解的主题。传记作家是有选择性的，因为没有传记可以成为一个完整的人生故事。在这个选择中，传记作者必须作出决定，他是判断的，还是他的读者可以形成自己对这个主题的看法的事实的选择。在这样的选择中，传记作者将允许他自己的观点和背景颜色他的选择。这是一种试图与传记的主题不偏不正的企图，因为传记作家被指控在一方面修复历史上的恶棍，或者诋毁另一方的英雄。关于臭名昭著的历史人物的修正主义理论可以引起强烈的抗议和谴责，正如大卫·欧文的阿道夫·希特勒传记所描述的那样。即使有了所有的问题，它们仍然是一个很好的信息来源，读者如果不确定对主题的处理，就应该考虑其他关于同一个人的书。最明智的做法是交叉参考传记和历史书籍，使用不止一个来源，以获得更好更有见地的意见。
加拿大生物论文代写:人性的倾向
It is hard for the biographer, for instance, to rise above his own preconceptions and be truly objective. Biographies should be used as sources but it always should be borne in mind that they are often subjectively and not always objectively written. The one of the strengths of using biographies are that there is a direct focus on an event and the biographer might give an event more depth and detail than a general history book would and perhaps give it a human slant. Biographers can be biased, they are sometimes said to fall in love with their subjects. Whilst this maybe an exaggeration there is some truth in the fact that it is hard to be objective about a subject that the writer has analysed in depth and feels they understand. Biographers are selective through necessity as no biography can ever be a full unvarnished story of a life. In this selection the biographer has to make a decision as to whether he is judgemental or whether he presents a selection of facts from which his reader can form their own opinion of the subject. In presenting such a selection, the biographer will be allowing his own views and background colour his choice. It is the attempt to be even-handed with the subject of the biography that can cause controversy as the biographer is accused of rehabilitating history's villains on one hand or denigrating its heroes on the other. Revisionist theories about notorious historical figures can cause outcry and condemnation as was well illustrated by David Irving's biography of Adolf Hitler. Even with all the problems, they still are a good source of information and the reader should always consider other books about the same person if they are unsure of the treatment of the subject matter. The wisest thing to do is to cross reference biographies/history books and use more than one source, in order to get a better and more informed opinion.
