- The inability to discard old skills is different from the inability to learn from new messages.
- "Espoused theories (what we say or think about how we act
) and theories-in-use (what our actions reveal about how we act
) are different
. People are usually unaware of the discrepancy between these, and a fundamental aspect of learning is recognizing and dealing with it." Orlikowski, W. of MIT (1999)
