I think this was already covered but...
Babs is sometimes an action figure that is called a doll, but she is clearly sometimes an action figure -example: Elektra.
The Bild Lili design that inspired Babs was different than previous incarnations of "dolls".
Barbie may be the world's first deliberately misnamed figure. While of a doll type, she is clearly not in the mold of previous dolls.
I have to agree about McFarlane. Poseable statue is about the only name that can apply. Certainly not a doll.
1/6 is also in question. Only some of the more recent Sideshow figures are 1/6 scale. Consider that SMG is around 5'3" yet her figure is around 5'9" Not exactly 1/6*.
Not forgetting that Luke "aren't you a little short to be a stormtrooper" Skywalker is now 6' tall!
Here are some suggestions for terminology based on actual defintions:
Action figure -Fully Poseable (arms legs etc) figure capable of active(combat etc) poses.
-Doll type - cloth clothing
-Toy Soldier type -molded clothing
Doll
-Mannquin type -actual fashion doll
-Toy type -baby dolls
Poseable Statue -moderately poseable (6 pts or fewer) figure with limited mobility without cloth clothes.
The poll question is flawed and is really unanswerable.
*The new DML-style figure BVS figures put her at 5'6"
