Please tell me where you live so I can move there. My flies are as dumb as ever, I can't even get them to go out the window with me actively trying to kill them. They rather take their chances with the swatter or get tangled behind the curtains.
From an evolutionary perspective it would seem wrong to actively go towards the source of stress when the opposite direction clearly leads to safety. But then again what do I know. Perhaps my flies are adrenaline junkies.
