I suspect the underlying bias is, "have I heard of this before?" If not, it's more likely the entry gets rejected. The more homogeneous the population of editors, the more narrow their experience scope. This is amplified by external biases that make women's contributions less visible - it's harder for new awareness to be built. Just a theory.
