Similarly, when your therapist asks you a question, your answer is skewed by what you want the answer to that question to be. Or what you want your therapists reaction to your response to be. Or any number of factors.
This idea has led me to start doubting my subjective experience of basically everything. Do I not like someone because of how they act or do I not like them because I don't want to like them? Did I study computer science because I enjoyed it or because I wanted to make a good salary? Not to mention that other peoples' subjective experiences are probably even less reliable.
I have no idea how to answer my therapists questions because I don't trust the answer in the first place.
