Hard to speculate on the psychology of the Cirrus 'chute not being a psychologist but I think Pace has probably hit the nail on the head with his 'more Cirrus accidents, more pilots walk away' comment.
So you have to say that if the Cirrus didn't have a 'chute then there would be less Cirrus accidents for pilots to walk away from.
It would be interesting to look back on say the last five years GA accidents in the UK and say which ones would have had a better outcome if there was a 'chute available.
