Hubble bias

When the Hubble Space Telescope allocation team launched dual-anonymous peer review for Hubble telescope time, the demographics of successful Principal Investigators (PIs) changed:

increasing the fraction of successful women PIs (such that the percentage of successful women PIs came within a point or two of successful male PIs), but also increasing the fraction of first-time PIs, suggesting that not only was there a historical gender bias but also a seniority bias.
