I believe that the intertype relations are reliable enough that we can use them to help determine a person's type. For instance, if someone has your ignore function as their base function, you will often find yourself feeling a little bit bored, and the two of you will be lacking anything to say to each other. This is especially true with an Extinguishment relation. And all the other relations can be used this way, too, to provide information about people's types.
We will use one person whose type is well known and agreed upon. It doesn't just have to be a chat with me, although since this is my idea, I'm offering to be the person you chat with to test your type. Many people agree that my type really is a SLI, although there are a couple people (at least one) who disagree. So I can be used to test your interactions with a SLI, and see if they go as the intertype relations would predict. If they do not, we may want to question what your type is.
Anyone else want to do this? We'd have to schedule appointments at a particular time to chat. I'm on Eastern Standard Time. It would help if we had more testers besides just me, so that we can observe several different relations.
