When I learned my way around a bass, I established that the center detent on the blend knob is pointing up towards the pickups. The knob has a marking on it, and when it is centered, the marking is pointing up, meaning they are blended 50/50. When I turn the knob clockwise, the marking on the knob points to the neck pickup, meaning it has more power. When I turn the knob counter clockwise, the marking points to the bridge pickup. You just happen to have your reference point, the center detent, pointing down.
I prefer Fender style knobs with no markings. On my basses with pan controls, I would always use the set screw as indicator. I would tighten the knob in place so that looking down at the top of the knob, set screw pointing straight up indicated 50/50 blend (detent). With standard wired pot, moving the knob clockwise moves the set screw towards the neck pickup. This is certainly no less logical and no more ridiculous than the other way of thinking about it. Bottom line: everyone is correct, and we can all sing kumbaya together.
