Legitimate Peripheral Participation
You don't learn the thing then join. You join at the edge and the doing IS the learning.

What it actually is
Legitimate peripheral participation (LPP) is the theory that you learn a skill by doing real low-stakes work on the edge of a real community, not by studying in isolation first. Coined by anthropologist Jean Lave and computer scientist Etienne Wenger in their 1991 book Situated Learning: Legitimate Peripheral Participation. The newcomer is the 'peripheral participant' — legitimate (genuinely part of the group, not a tourist) but peripheral (handed the small, safe, real tasks). Learning is not a thing you download into your head. It's a process of moving from the edge to the center of a community of practice.
The mechanism: situated learning
Lave and Wenger flipped the standard model. Knowledge isn't abstract and transferable from a classroom into 'the real world' — it's situated, meaning it only fully makes sense inside the activity and social context where it gets used. The newcomer absorbs the community's vocabulary, norms, shortcuts, and identity by being there and contributing, not by being lectured. Three things have to be true: your participation is real (it matters to the group), it's peripheral (the failure cost is low), and there's a visible path inward. Strip any one and it breaks: no legitimacy = you're ignored; no periphery = you drown; no path = you stay stuck at the edge forever.
