Does " 12 of those were bounced" mean " 12 of the most highly cited papers were pushed backed to the authors by editors (the editors recommend that the authors should improve their papers before seeking publication"?

12 of those were bounced before they could reach peer review. The finding suggests that unconventional research that falls outside the established lines of thought may be more prone to rejection from top journals, Siler says.
