As you point out, the nordic countries show that perverse incentives don't necessarily follow from Socialism. And indeed, America has its own non-Socialist perverse incentives such as encouraging pollution by not enforcing payment of the environmental externalities.
But all things considered globally, more socialism does tend to imply more perverse incentives.
However you end your comment by an unfounded claim that more socialism tends to imply perverse incentives. The same could be claimed of capitalism (or probably any other ..ism), see the banking sector and American healthcare for good examples.
In the rather socialist Denmark (where I happen to be from) when you break a leg you go to the doctor to get it fixed for free, and then you call your employer and tell him you won't be working for the next week, but you'll receive your paycheck nonetheless. When you get a child you take 9 months off work with full pay so that your offspring can get a good introduction to life. When you're out of a job the state will take care of you indefinitely.

Note that the socialist nordic countries have stellar economies.
I've noticed a lot of Americans blame the euro crisis on socialism which,is interesting since it doesn't seem to hold up to scrutiny. I'd be interested in hearing why this is. Is it the media, an American distrust of socialism or something else?
