Very interesting. The difference between the "German glider" decision problem and the Bakshirian one is that the B747 knows the non-painted conflicts are above him. Bakshirian doesn't know that.
The "German glider" decider is therefore able to maintain altitude without conflicting with non-painted traffic, and equally able to hope that the intruder is TCAS-equipped and responds to a descent RA. The "Bakshirian" decider is not able to maintain altitude without conflict with non-painted traffic, as far as he knows.
The German-glider decider can follow the dictum not to manoeuvre contrary to an RA. The Bakshirian decider cannot follow this dictum without risk.
