Yes they do.
And there has been numerous tests showing it by just about every company.
Grooves channel away debris, so depending on where you are playing from will have a factor, but less spin will not only alter control of the ball, but flight as well.
Ya I agree with that simple explanation of it, although I know some golfers using 15 year old Taylormade irons that shoot like high 70s low 80s. But if your anything like me (changing clubs frequently) you probably will never experience that problem since iron last alot longer than drivers.
