>…but I have NEVER heard a company claim that they were 90% powering for an efficacy of x, because they figure x is the worst efficacy can be and still be sellable.<

I have heard this but it’s not phrased in such crudely commercial language. Management says, “We surveyed 150 of the leading clinicians in this field, asking what magnitude of treatment benefit would induce them to change their treatment regimens to incorporate our drug. They told us __%, and our trials are powered at 90% to show such a benefit.”

“The efficient-market hypothesis may be
the foremost piece of B.S. ever promulgated
in any area of human knowledge!”
