Actually, it was the exact opposite. People said the world was flat and scientific measurements were what disproved what people widely held to be true.

The experimental concert (entitled Infrasonic) took place in the Purcell Room over the course of two performances, each consisting of four musical pieces. Two of the pieces in each concert had 17 Hz tones played underneath. In the second concert, the pieces that were to carry a 17 Hz undertone were swapped so that test results would not focus on any specific musical piece. The participants were not told which pieces included the low-level 17 Hz near-infrasonic tone. The presence of the tone resulted in a significant number (22%) of respondents reporting anxiety, uneasiness, extreme sorrow, nervous feelings of revulsion or fear, chills down the spine and feelings of pressure on the chest. In presenting the evidence to British Association for the Advancement of Science, Professor Richard Wiseman said, "These results suggest that low frequency sound can cause people to have unusual experiences even though they cannot consciously detect infrasound. Some scientists have suggested that this level of sound may be present at some allegedly haunted sites and so cause people to have odd sensations that they attribute to a ghostour findings support these ideas
Sorry if I've taken this thread off course, I just had to defend my position here.
I think it actually does the opposite. You have long argued that there was no need for subs capable of producing sound below 20Hz or so. This proves that those frequencies do have an impact. When in real life do you hear those frequencies? Explosions, earthquakes, building collapses, collisions, etc. right? Don't you expect to feel one or more of those reactions if you were there? So wouldn't being able to reproduce those frequencies be beneficial to feeling more immersed in the movie during those types of scenes? I would think so.
Now back on topic. IMO, the only way a sub can sound bad if it measures well is if the measurements were not taken in room. If I were to buy a sub that measured well by someone in there environment and take it home only to find it sounded like crap I can't blame the sub unless I have the same setup as the person who took the measurements. My room would have to be made the same with the same dimensions, furnishings and treatments while using the same components that measure the same or close enough. Only then can I say the measurements are valid. Subs will measure differently in every room. Room acoustics play a significant role in how a sub sounds.
The second reason a sub may not sound good if it measures well is due to preference and what the listener is accustomed to. As had been mentioned before, some people are used to distorted, boomy, bloated base. When they first hear clean bass, they are not used to it and think it sounds thin and lacks fullness.
One more note. Sounding different doesn't necessarily mean they don't sound good.
