Hi Jeff, this is excellent awareness on your part. The "societal" notion of responsibility is that if we are beating ourselves up, or, if we are doing what we are supposed to do -- even if we don't like it, we are "being responsible people" or even "taking responsibility." This research raises the bar to look at the true mental state of Responsibility where we are much more resourceful and feel much more free, powerful, and at choice.
What we have learned over the last couple of decades of working with smart, ambitious, and successful people is that professionals tend to hang out in Shame and Obligation as that is what we were programmed (conditioned by well-intended parents and teachers) to do.

I do know I use the verbage as a form of training for my co-workers. I will often state use statements that "Maybe I did it because I'm not terribly bright" as a means to dismiss other individual's intent of looking for someone to blame. I think there is value in making the statement (as a joke to difuse tense situations) has value; but now I have make sure I am not believing what I'm saying.
