These explanations would benefit from having the echo they deserve. While we obviously find studies reporting recruitment or advancement bias among researchers (sometimes also in the opposite direction to that usually suspected), it seems that overall in France we can explain the disparities only by the choices made and scientific productivity, namely the fact of applying and publishing [(Mairesse & Pezzoni, 2015); (Bosquet, Combes, & Garcia-Panalosa, 2014)], a differential which itself is explained, at least in part, by family commitments. Overall, by looking closely at the data, it is clear that the mystery of the "glass ceiling" seems to have been elucidated.
