if you think about it - it does makes sense, in general..
IF you do have a tailplane (ONLY) stall
less flaps will reduce the required tailplane downforce
and a pull back will increase the camber of the tailplane and reduce the aoa of the whole tail and get it to fly again.
however, if you're not trained for that I doubt you'll recognize what actually happened, especially given the little amount of time they had in the Colgan Air event.

Tail Stall:
Pull back on yoke
Reduce flaps
Reduce power

Nothing.
For whats its worth prospective fragrant harbour wannabees. I have my IQAir set to its highest level and thank god I don't have a wife and family living here.

ps My wifes exact words the other day, 'if I knew how bad the pollution was I would have stopped you from joining Cathay'

The tail did not stall on this airplane, the wing stalled first, hence the activation of the stick shaker (the stick shaker is referenced to the AoA of the wing not the AoA of the tail) and eventually the stick pusher, followed by a classic spin entry. The airspeed was left to decay to 120kts before the power levers were touched.
If they couldn't recognize a stall I doubt very much that they would have been able to recognize a tail stall due to ice. The flaps should have been left where they were.
