Ranking factors for difficult paper

  1. Subject matter complexity
    The depth and intricacy of the concepts and ideas discussed in the paper, and the level of understanding required to comprehend these concepts fully.
  2. Technical language and jargon
    The extent to which the paper relies on highly specialized language, terms, and symbols that require prior knowledge or expertise in the field.
  3. Logical structure and organization
    How well the paper is organized, and the clarity with which the arguments and conclusions are presented. A well-structured paper will be more understandable, even if the subject matter is complex.
  4. Novelty and originality
    The extent to which the paper presents new ideas or challenges existing knowledge in the field. A highly original paper may be more difficult to understand, especially if it goes against established theories or paradigms.
  5. Interdisciplinary nature
    If the paper bridges multiple fields or requires the understanding of concepts from different disciplines, it can be more challenging to grasp fully.
  6. The intended audience
    The level of difficulty can depend on the intended audience of the paper. A paper aimed at experts in the field will likely use more technical language and rely on a deeper understanding of the subject matter than a paper aimed at a broader audience.
  7. Length and density
    The length and density of the paper can affect its difficulty – a longer, more densely packed paper may be more challenging to read and comprehend.
  8. Access to background knowledge
    Some papers may assume familiarity with specific background knowledge in the field. If this background knowledge is not accessible or well-known, the paper may be more difficult for readers without that knowledge.
  9. Quality of writing
    The clarity of writing, grammar, and punctuation can have a large impact on the difficulty of a paper. A well-written paper with clear language will be easier to understand than a poorly written one.
  10. The context within the field
    The importance and relevance of the paper within its field can contribute to its difficulty. If a paper is highly influential or central to ongoing debates or research programs, understanding it may require a deeper understanding of the surrounding context and related works.
