  • [Editorial] A swan in the making
    [Aug 2014]

    Reproducibility is the ugly duckling of science. It provokes distress, denial, and passionate calls for action. With $1.5 trillion spent globally each year on R&D,* the idea that 80% of it is irreproducible† can cause downright dread. It threatens the foundations and credibility of the scientific enterprise. But look past the surface, and reproducibility may well be a swan in the making. Author: Timothy Gardner
