Balls tend to roll all over the damn place, scarves pretty much land at your feet, increasing your actual juggling time, as opposed to looking for stray balls under the couch time.

This was addressed in Hautala’s research.
Time-on-task is the biggest factor in successful practice. I believe he found that people who practiced with beanbags had the highest success rate because they didn’t roll away when dropped, and more practice time was attained.
And I don’t mean to belittle your personal experience. Scarves may very well have worked for you.
As a professional performer and teacher of juggling (meaning, I did it for a living) my goal was to teach many people quickly and effectively. That meant I had to use the best techniques I could find.
At one time, about ten years ago, I read just about every piece of research ever conducted on juggling. There wasn’t very much, but I went carefully through what was there. That and my experience over the years has convinced me that scarves aren’t that helpful if your goal is to eventually juggle balls.
But that might not be important, really. Part of the fun is the process, which in the end is very personal. But I believe in efficient teaching, so I try to share my experiences when this subject comes up.
In a nutshell, the most important aspect of juggling is the timing (see Beek’s work on dynamical sytems theory). Catching is incidental, in my experience. So throwing and catching one ball is usually a waste of practice time. As is changing the fundamental timing of the skill with scarves. It’s throwing one object in relation to another in real time that is the crucial element.
However, motivation is another matter. Maybe success with scarves gives people a mental zing that inspires them to try harder when they move on to balls. I’m not aware of any studies on this, but one tries to keep an open mind.
Apologies for the hijack, but this stuff is endlessly fascinating to me. I’ve never tired of learning how we learn and how best to teach.
