Greetings @Cryptogee
Transference and Counter-transference might be related to this "anchoring".
I agree, Anchoring is an interesting way to "manage" emotions. Although this technique does not work on some people, in can be very helpful. What's important thing to keep in mind before utilizing these kind of techniques/concepts is insight. The person should have good insight of his condition. Just to add.

Insight is the proper understanding of ones condition and full awareness of whats happening to oneself.

Overall, this is a great informative article. More power!
