Not even in "small" fields. A lot of the time any new work is just a further development of previous work by the same author. So if you're well read in your field, that "double blind" peer review is not blind at all.
Of course, this is hard to do with cell cultures and such, and in the case of large databases or compute-intensive tasks it's not quite feasible. But a surprising amount of what goes on in CS and neighbouring disciplines can work that way once you work past the reticence of individual established authors and set it as a goal for your (sub-)field.
