Let me give you an example where this has a very practical use. I has taken me years to get this.
Say if you are 18 and you go and work in construction ,the other guy's there will want to figure out your personality. How you respond. They are like us in this respect they need data , and they need to build a predictive model of your behavior. They don't have enough information on first contact, so they test. This is the kind of test they give to assess if you are stupid.
Test - " Harry needs a bucket of steam , go and get him one will you."
A " stupid " NT won't know steam can not be contained in a bucket , some water molecules will escape and those that don't will revert to liquid as they condense on the sides of the bucket. You of course will, you are not stupid in this way.
You are not stupid but they won't know that because you implicitly trust them you think they might use a product called steam and require a bucket of this product . You reason it would be improbable to call a product steam , hence you might have misheard, you might actually be going to fetch something with a similar sounding name, "stream", "steem,"- steem might be one of those German paints, perhaps that is what they mean...
They will not grasp you reasoning capacity or your intent and they will label you as stupid, and you will have to work very hard to overcome this label, and the real bullies will circle in like sharks having watched you miscalculate the meaning implied in the tease, and they will use it to get a hold on, expand on it and make your life hell.
However if you had done reverse-tease and said " do you want me to fetch a bucket of Gloopenstein as well, its like normal steam only a different color" and kept on with reverse-tease
it becomes a joke and they may even laugh, with relief you have passed the test, and they don't have to use their time and energy protecting you socially from every psychopath working on that construction project.
Here's the important thing: It doesn't matter if there actually is a product called Steam, or Steem they want you to fetch. That you have questioned the directive they have given on the basis of the information is enough. That is what they want to see. Hence if something is improbable , question it in a friendly way. But not too often because this can have the same effect as placing implicit trust where it is not deserved.
