Or is the training regime acclimatising them to a rather benign situation which leads to over-confidence
this is still a relevant question.
By chance I just found a 2007 Canada TSB accident report which addresses this subject - I have posted a bit of background under the Halifax A320 accident thread but the recommendation 07-03 is "The Department of Transport mandate training for all pilots involved in Canadian air transport operations to better enable them to make landing decisions in deteriorating weather."
Alf- Disk arrived, thanks.
