"And not just audio. Any scientific pursuit from medicine to taste
comparisons of soda uses DBT"

The only thing medical drug research DBT tests have in common with
audio component comparison is the name.
The medical tests' subjects subjective responses are always compared
with and validated by FACTS: outcome of the disease, laboratory and
Xray results.
Otherwise the positive responses (" I feel better") to a placebo, or
quack mumbo jumbo would have equal validity with objective outcomes.
Compare!
