    Reasons For

    1 perspective
    Reason for
    ?
    • 1.String theory has the potential of explaining why there are three generations of elementary particles by invoking the Euler characteristic of the compact spaces it employs
      ?

      Think about whether this reason is strong or weak

    • 2.The Euler characteristic is equal to twice the number of generations
      ?

      Think about whether this reason is strong or weak

    • 3.This provides a potential explanation of a previously inexplicable piece of old empirical data
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    2 perspectives
    Reason against 1 of 2
    ?
    • 1.Post-hoc accommodation of known data provides weaker confirmation than genuine novel prediction, per Lakatos's distinction between progressive and degenerative research programs.
      ?

      Think about whether this reason is strong or weak

    • 2.The Euler characteristic argument was constructed after the three-generation fact was known, making it accommodation rather than prediction.
      ?

      Think about whether this reason is strong or weak

    • 3.A theory that can accommodate virtually any number of generations by selecting among ~10^500 vacua lacks the discriminatory power required for genuine explanatory credit.
      ?

      Think about whether this reason is strong or weak

    Reason against 2 of 2
    ?
    • 1.Popper and Dawid's debate over 'non-empirical theory assessment' reveals that internal coherence and explanatory promise cannot substitute for empirical testability as confirmation.
      ?

      Think about whether this reason is strong or weak

    • 2.String theory currently makes no predictions distinguishable from the Standard Model at any experimentally accessible energy scale, leaving it empirically equivalent to infinitely many rival frameworks.
      ?

      Think about whether this reason is strong or weak

    Curiel goes on to question, more generally, the ranking of approaches to quantum gravity given what he views as the absence of demonstrated scientific merit in any of them: elegance and consistency might well be merits of a scientific theory, but they do not count as scientific. (ibid, p. S437). However, this claim hinges on the direct alignment of scientific merit and empirical clout; but this requires an argument, for it is far from obvious: from whence this prescription? Surely if a theory is
