This isn't only limited to bass. In general everyone has a reference. This could be their own feelings (what they believe, what is right) or it could be "what exactly is on the soundtrack" (here comes then the technical aspects such as linear frequencies and so on), or live experiences / concerts.

What is true for someone isn't for others. Therefore personal affirmations that this is right, coherent, natural and all those great words, which have psychological effects on other people,  don't have really any value nor sense except for the person who uses those words.
