When we use the term "motion blur" we're talking abut slow shutter speed? Or are we talking about a user who can't hold the darn camera steady?
I'm trying to apple the 2X focus length formula for shutter speed and trying to improve my technique but am really struggling. On the other hand I'm wondering if I'm too much of a pixel peeper.
With people you need to consider motion blur = your subject moving. There is nothing you can do on your side to prevent this. Even a camera on a tripod will not help. Only faster shutter speeds will take care of this. With people I tend not to go below 1/125; optimally 1/160 and very rarely below 1/80. The lower the shutter speed, the bigger the probability that you have motion blur.
Then there is camera shaking, which can be minimized by many different ways: tripod, image stabilisation, good stance, breathing and/or faster shutter speed.
Appropriate fast shutter speed will take care of both - but it is still good to know what you need in which situation. As I said, I am comfortable to take hand held pictures at 1/40 for stills, but not below 1/125 for peoples. (edit: forgot to mention: on my narrow end of my beloved 24-70).
