IFR pilots can more easily be lured into making riskier flights.

I adamantly disagree. In obtaining my instrument rating I learned MUCH
more about weather and weather analysis than I knew prior as a VFR only
pilot. And I am much less inclined to fly VFR in marginal weather or
IFR in weather than either I or my airplane aren't fit to fly.

I had far more weather close calls as a VFR only pilot than as an IFR
pilot. I actually can remember only one close call since getting my IFR
rating and that was an icing encounter lee of Lake Erie. And that was a
flight forecast to be VFR all the way and which I could have just as
easily encountered on a VFR flight and would have been much less capable
of dealing with.
