My point : number of trials should be specified before a DBT begins

I believe specifying the number of trials at the outset is a requirement if the test is to be considered scientific. If I were doing a DBT at home, I would decide on the number of trials before starting and stick to that number. I could be faulted for deciding to change the total number of trials during the test. Would it be fair, for example, for me to quit after scoring correctly in 12 of the first 16 trials, because in a test 16, 12 correct is a positive result?

A listeners doing an informal blinded test at home, however, may find it difficult to meet all requirements of a scientific test. That is why I said "who cares" when referring to specifying total number of trials in an informal test.
