I would think that with something in the nature of designing a product for consumer use, along with the safety implications, preferences for consumption of a product, etc. Double blind tests would be of great value in narrowing down how a consumer chooses.
Educators already use it (in a different form) and even in politics, with people unaware as they participate, in group surveys and focus groups (they unwittingly reveal preferences in which way a phrase or word is used). That was an extreme example but it's done all the time.
I just resent it that it's always hauled out in these threads as the answer to all differences and does nothing, really, to further discourse and enjoyment. But in the end, like you said, it's all good. 👍
All the best,
