I honestly made it up on the spot, so don't take it as proper nomenclature. However, to describe it another way: the unconscious mind synthesises its emotional choice, which the conscious mind presents as rational fact. If you want to know how the mind arrived at that conclusion, you've got to go on a fact-finding mission, i.e., asking why.

However, asking that question without triggering a negative response is an art form within itself. Rarely can you be so direct, which is why it's often much easier to watch how a person interacts with a product rather than asking them why they did what they did.

Causal shielding feels like a better term in this case
