    In order to present the results of a subjective analysis, it is
    important to prepare the analytic procedure such that you can convince
    any number of people that you have proceeded in a scientific method.
    The double-blind test is a scientific method; honesty and sincerity do
    not enter the picture.  Example:  'I performed a double-blind test in
    which I ABXed two speaker systems.  I identified speaker A 15/16
    trials.' - this is a typical example of the verbiage used to document
    many such 'double-blind' test procedures.  It is honest and scincer,
    but it lacks description of scientific method.  This is the format many
    documented double-blind testare found in.  It is inadequate as it shows
    no evidence of scientific methods or procedures; only objectivism and 
    naivete to scientific method.

    I assume that honesty and sincerity are inherent in a test report.  I
    expect process and implementation to be explained in detail; only then
    can I take a report seriously.
