objectivity- thick facts, no mood or tone from the author.
extremely descriptive- Any death or sex scene will be explained to you to a T
pessimist/depressive- The development and end is always catastrophic.
influenced by Darwin's theories- No "nature vs. nurture". If the character is poor it will remain and die so "because that's his/her nature"
appeals to human emotion- facts are crude to exalt your feelings.
