Why don't they just ride properly?
Becuase beginners use the reins for balance and with that tends to come the excessive lifting of the hands.
...only if they haven't been taught, as they should be, on the lunge first. Something is terribly wrong in the heart of the way you are being taught to ride in the UK (I won't even START on the total vacuum that is Ireland....), but that does explain a lot of the problems discussed so often on here.
