No, it doesn't. That is a specific example of misunderstanding what is being said - or a deliberate attempt at strawmanning. I've said that science and evidence are required here to back up what is being said. At no point does that mean that science can determine (especially) personal preferences - where differences in behaviour of equipment actually exist - as they do between speakers, and the interaction of those speakers in rooms.For example, can you tell me, using measurements alone, which is the best speaker out of the three I mentioned earlier: JBL M2, Genelec 8361 or Revel F228Be. Your quote above suggests a ranking system is possible, and therefore the best could be deduced, from measurements alone.
What the science *does* say about speaker measurments (I'm treading lightly here, because I am far from familiar with that science myself) is that a preference score can be given based on measurements.
However, as you have correctly pointed out that is a score based on a strong majority preference, not that every single individual will share that preference. And I've not seen anyone credibly saying anything different.
