The Transfer Deficit
The empirical finding — documented by Christakis and others — that skills learned in digital environments do not transfer to the physical world, revealing that medium and learning are inseparable.
The transfer deficit is the experimentally demonstrated phenomenon that children who master a skill in a digital environment cannot reliably apply that skill to the physical world. Christakis's paradigmatic example: children who learn to stack virtual blocks on a touchscreen, when presented with real blocks, start over from scratch. The virtual stacking did not generalize because the stacking skill is inseparable from the medium's affordances — the snap-to-grid precision, the absence of gravity's tyranny over imperfect placement, the frictionless environment in which every block is placed as intended. The child learned something. What she learned was specific to the conditions under which she learned it. The finding is foundational for evaluating AI-mediated learning: the question is not whether the child acquires a capability in the AI-assisted condition but whether the capability transfers to conditions the AI does not mediate.

The mechanism is consistent with broader findings in transfer research: skills are encoded with their contextual
