This year at LILA, we explore the theme of unlearning, this time, adopting a systems perspective. Unlearning is what we face when we are trying to learn something new, but prior learning gets in the way. LILA’s own David Perkins notes that even though we can’t really UNlearn, it is helpful to have a name for this type of learning as it presents unique challenges. While trying harder often succeeds in moving outdated skills to the fringes of our repertoire, some things resist even our most earnest attempts at sidelining. In these stuck cases, Dave suggests that, instead of trying harder, we change the game. Before imagining how we might design game-changers for our organizations, we look at several tools, models, and theories to test if and how they might help us understand the nature of system stuckness.
