Reinin in [one of] his book(s) says that duals can manipulate each other through direct suggestion from the leading function. I would say that we all are vulnerable to suggestion from society and people in general regarding our "suggestive" function, especially if we are not aware of it. I am conscious now of some instances where people
tried to (consciously or not) manipulate me. This is strongly related to hypnosis. I don't know how aware are people about this but this is something that has caught my attention for some time, and it would be helpful to get some food for thought from other people.
note: semiduals, activators, and other people that have our suggestive as a strong function can manipulate us in this regard.
