I would usually not get this type of inner voice in my life. At the few times that I do get them, I mostly would catch myself when doing it. The situations that i get them is when i do something wrong and make an mistake.
Inner Defender is like a defender like the name says. Instead of blaming or complaining oneself, it judges others. It tends to fend off criticism and punishment from others. An example of inner defender is like saying I would have gotten a A if the teacher was better.
