In lay terms, backsolving evaluates a position assuming best play from both sides. Of course you have to be correct about the evaluations of the ending positions, and you have to assume that you have all viable moves, but even with those two huge assumptions, backsolving is a better method than simply looking at which move has historically done best. One reason that looking at historical statistics is that when a new good move is found, it may be quite succesful until it is refuted, but then once it is refuted, the whole line may be abandoned. Thus, from a statistical point of view the line looks great [because the statistics will be skewed by all the earlier games where the line was doing well], but trot that out on the board and you may be well be playing a busted line.
