When I first read about this effect years ago, it was accompanied with the advice that careful study of the scene which you are photographing is enough to offset the effect (and perhaps even amplify memories). I suspect that in "casual" photography, the photographer is simply focused on getting the camera turned on, pointing it in the right direction, and remembering to press the shutter, rather than the scene itself, and hence form no memories of the scene.
