English has a lot of rules that most native speakers know on an instinctive level, but could not explain to a non-English speaker. Order of adjectives is one of those rules, and it’s pretty neat to see how it works. If the order of descriptive words in a sentence is jumbled, it will just sound weird and confusing. The average person could correct the order so that it sounded right, but they likely couldn’t tell you why it was wrong in the first place. Sometimes the order matters, and can change the meaning of the sentence, but often it’s just a particular flow that we’ve all learned through exposure.
The key thing is, most people were not aware that they were learning it, and don’t know they know it until it is pointed out to them. Obviously, not everyone speaks the same way, and I’m not making any argument for the virtue of these types of grammatical rules. I’m just saying that this is an extremely pervasive thing in the English language. It is part of us, and most of us aren’t aware of it.
That’s why it makes such a great example of how prejudice works. If you can know how to order your words according to rules you never knew you learned, you can learn a whole lot of other things without ever being aware of them on a conscious level. Not all of these things are harmless, and many are not based in fact, but they are taught to us all the same, in a million subtle ways.
It’s easy to get angry and say you’d never choose to be racist, but the thing is that you never chose to order your adjectives the way you do, either. It is simply the way speaking is done. In fact, there’s no possibility of choice being involved if you aren’t consciously aware of learning something. You do not need to be a grammar snob to follow the basic rules of English every time, and you don’t need to be a hateful person to experience the instinctive fears and prejudices that are a part of our collective culture. Choice isn’t involved until someone makes you aware of what you believe, and the consequences of what you believe, and that’s not a pleasant experience.
It’s tempting to rely on your conscience to alert you to these sorts of issues, but that’s no good. Consciences aren’t magic. They’re actually pretty terrible judges of what is wrong and what is right. They’re much better judges of what is familiar and what is foreign. They’re formed on the same instinctive level as language, at around the same time. It happens when we’re children, and what we learn is generally reinforced for the rest of our lives by our environments. A person can be loving and generous, and also harbor terribly harmful beliefs about others. The only way to change that is to be willing to handle the shock of having those beliefs challenged. It will often feel, not just uncomfortable, but wrong. Incorrect. Against the proper order of things.
