Two words: Bounce rate.
I have more than enough data to support that statement.
Is that "bouncing back to the SERPS" or the general bounce rate, like you would see in Google Analytics? I have some sites with a high GA bounce rate that do just fine in ranking. The high bounce rate seems related to clicking on an ad and following on to a different website, vs back to the serps.
