Well, I think the wording would be more accurate if it said:
* It's counter-intuitive, but [displaying] more payment options reduces sales [in tests we've done using our methods].
Agreed. My original wording implied knowledge of broad external validity that I do not have statistical proof of.
Still, to return to the thread's topic, a Bitcoin civil war would be a very, very bad thing for my firm's position on Bitcoin. As it is, this block size stuff is making us really nervous. I hope the brilliant minds at work on a solution can figure this out (preferably sooner than later).
