"The grads were interviewed by people linked to AARC. This could bias what was reported, Alexander said. “Imagine calling up somebody who’s graduated from a program and saying: ‘Hey, are you taking drugs any more?’ And this person has already been put in the program against their will perhaps precisely because they took drugs. And what are they going to say? ‘Oh yes, I’m taking lots of drugs now,’” Alexander said."
Maybe you could address the above comment, or the fact that your Dad, along with the Wiz, and Natalie Oldcomer wrote the study, passed it on to Herard, who then claimed that the study was written by Patton, which it wasn't, and that it showed that 85% of the sample population were still sober after 5 years, which it didn't.
The mean time since graduation was just over 2 years, not 5, and only 48%, not 85%, reported being still sober since graduation. Taking into account what Alexander said, there is no reason to believe any of the data gained in the interviews. In light of the fact that parents are the ones invested in AARC's success, and will reject their offspring in favor of AARC, it's one more reason to attribute bias to the interviews.
It's never hard to catch you folks in an outright lie. As always, you have my gratitude for your unbridled willingness to lie pubicly, and to embarass yourself by attempting to support your church's deceptions.
