Parataxis

Much of what I've learned from Walls' video short on authenticity and the New London Group's writings on Pedagogy is that at a very human level we have selective awareness. For this reason, agents such as advertisers or teachers can emphasize key important aspects of a specific theme. The ramifications this has on culture spans modern colonial history, as cultural, linguistic, or racial others were tokenized by what seemed to be defining characteristics of them, when in fact what was represented was a simplification or an exaggeration of some larger trait. In this way, "authentic" can lose its literal meaning, and instead it can be used as a symbol to introduce ideas that could be a selling point.
This means that we are capable of understanding language in multiple ways, and that sometimes this can happen outside of our control or awareness. Our instinct to see a symbol and associate it with a concept proves that we are multilingual creatures, and that we communicate in ways besides our most obvious uses of language and body language. Our brains analyze, interpret, and offer our bodily selves a mash of things we can recognize, so conclusions are drawn instantly.
What we can do, despite what seems to be totally out of control, is work within intellectual thought processes to unpack what it is our brains are doing to us. We can realize that conclusions may be rashly made, and like Wells says, we can actively pair advertising words with products that don't agree, and see how the effect can be tonally dissonant. By feeling this reaction as instinctively "wrong" in the same way that authentic Mexican feels instinctively "right," we can understand the "authentic" provides a superficial satisfaction.
