My goodness gracious talk about getting it all wrong. First ABX DBTs
involves playback equipment. Pharaceutical trials do not so there is
nothing to "calibrate" in pharmeceutical trials. BUT they do use
control groups! That is in effect their calibration. without the
control group the results mean nothing because there is no
"calibrated" base to compare them to. So in effect they most
defintiely are calibrated or they are tossed out as very very bad
science and just plain junk. That is bias controlled testing 101.

This is simply misinformed nonsense. The standard is control groups
where their use is ethical. Many, many drug trial are conducted without
control groups. You simply cannot ethically give a terminal patient a
placebo, nor a patient for whom lack of intervention results in
permanent injury. And yes, I *am* involved in one of these as we speak,
so please spare your speculation. In this regard, drug trials are
significantly different than many DBT's.
