    It is not the case that Descriptive complexity results are sensitive to the choice of encoding, so the boundary between FO and stronger classes is not a fact about logic alone but about logic-plus-structure.

    ?Set your confidence on the premises below to see your aggregate.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Different encodings of the same structure are informationally equivalent; relabeling vertices doesn't change what FO can express about it.
      ?

      Think about whether this reason is strong or weak

    • 2.The expressive gap between FO and second-order logic persists across all reasonable encodings, suggesting the boundary is logically robust.
      ?

      Think about whether this reason is strong or weak

    • 3.Sensitivity to encoding may reflect artifact of proof technique, not a deep dependence of logical power on representation choice.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.The same finite structure can be encoded as ordered or unordered, with/without successor, yielding different FO-expressibility boundaries.
      ?

      Think about whether this reason is strong or weak

    • 2.Encoding choices are conventional tools, not intrinsic to logical power, so descriptive complexity reflects the tool-structure pairing.
      ?

      Think about whether this reason is strong or weak

    • 3.If boundaries were purely logical facts, they'd hold across all encodings. Since they don't, encoding is essential to the boundary.
      ?

      Think about whether this reason is strong or weak
