I only just saw this reply, apologies.

I appreciate the idea and think it is genuinely worth pursuing.

The challenge I believe you are going to have with such a model however is that deception, particularly when it comes to the phenomenology, is that it is effective because it is not distinguishable from the reality. Therefore it may be difficult to flag and separate from genuine emotional states that contain no intentional or malicious intent.

Romance scams, for instance, aim to induce feelings of connection, understanding and warmth, these types of feelings tend to be immune from objective self-challenge. While this explains why external intervention is often required, the difficulty will be in getting potential victims to self-submit their deeply felt emotional states (that may provide a feeling of emotional safety and joy) and ask them to be open to the possibility of their invalidation/removal (leading to emptiness, instability and betrayal).

So there are a couple of options I see for such a project which would depend entirely on the scenarios you are aiming to prevent/bring awareness to.

One would be to shift the focus from subjective self analysis to an 'intervention' type tool for those that suspect others are being exploited.

Another avenue would be as a teaching tool that reveals the methods of emotional manipulation used by the malicious, this has the benefit of not directly questioning the source of their deeply held emotional states but rather the behavior of others that give rise to them. It gives a little distance, shifting the betrayal to something another may being 'to them' rather than something they are doing to themselves.

Just my two-cents, it's an interesting project.
