Week 11: Legacy

Crossing 6's lecture — the only fortnight with no hallway work in it, and why assembling an honest account of the other five is harder than doing them was

19 October 2026

Open the slides

Still half and half, like every lecture — but for once not split between two people. George Curious convenes the course and tutors this Crossing, so one voice takes both halves: the idea first, then how to actually build the thing.

It’s the right lecture to be the odd one out, because Crossing 6 is the odd one out. There is no hallway work left. Nobody to approach, nothing to trade, no stall to staff, no stranger to build with. What’s left is the account of the five you already did — and the two rooms it has to survive.

First half — why the account is the whole Crossing

“Did you do the thing” has been answered five times over. That’s the easy question, and it’s now closed. Legacy is the other one, the one George has been asking since week 1: was it worth doing. You can’t answer that with a highlight reel.

The reason it’s hard isn’t nerve this time, it’s memory. McAdams’ life-story work is the frame: people don’t carry their past around as a list of things that happened, they carry a story with a shape, and the shape gets chosen — often without anyone deciding to choose it. Twelve weeks is not a life, but it’s long enough to have already acquired a shape you didn’t pick. The most available shape is the one where the bad bit turns out to have been worth it, and five of those in a row is a template, not an account.

Kahneman is the evidence for why your instinct about the semester is not the same thing as the semester. What you retain of an experience is closer to its most intense moment and its ending than to the hours you actually spent in it — the experiencing self and the remembering self keep different books. So the Crossing you now think of as the good one is data, but it isn’t the record. The record is the five clips, and whatever you said in the room the week after each one, while it was still close enough to the moment to be unflattering.

Second half — how to build it, test it and play it

The fortnight is two rooms. Week 11 is the Discussion Lab: no stage, no clock, no run-through — small groups talking each other’s semesters over while the account can still change. Week 12 is the Hallway Finale, your slot, your video, and then everybody else’s.

The Lab exists because an account feels finished in your head long before it is. Ask someone to rate how well they understand something and then to explain it step by step, and the rating and the explanation don’t match — the explaining is what finds the hole. Your account has only ever been explained to someone who was there for all of it: you. A peer who wasn’t there is the cheapest audit you’ll get, and the Lab’s spec makes you name, out loud, the Crossing you’re least sure about — which is exactly the one that goes quiet otherwise.

Craft, then. Ira Glass’s two building blocks are the shape of the whole presentation: the anecdote — this happened, then this — and the moment of reflection, where somebody says what the point of it was. Both have to be interesting. Five anecdotes with nothing said about them is a diary; a verdict on your semester with no five Crossings under it is an opinion.

Last, the video, because it’s the part that can quietly fail. Five clips, one per fieldwork Crossing, played in full, and they have to match what you’re claiming happened. Anything featuring another person can be taken back right up to the Finale, which is why Policies tells you to shoot a version without them as well — a clip withdrawn in week 11 is a gap in the video, not a story about consent.
