I think that not knowing the null results of others also slows down innovation, because you never know if an area of interest / whitespace in a field is 1) because there's something there or 2) because others tried, failed, and didn't publish. Maybe pre-registering isn't the right answer; I'm sure there are practical hurdles, but the problem to be solved still remains the same (visibility into the graveyard of failed experiments to improve the rate of innovation).
