I think this is a discussion about what the best order is in which debiasing should occur.

Project management seems to be an implementation of debiasing strategies and they first teach you to make more accurate predictions and then later teach you how to prevent the sunk cost fallacy from not cancelling a failing project.

Because of this i think debiasing should occur in a kind of logical order, one that prevents someone from cancelling all projects due to a good grasp of sunk cost and a bad grasp of utility calculations.
