Human as Model

◷ 15–25 min ▤ Role-play activity ✦ Critical / No-AI + Teach / Design

Three people play the roles that exist inside a language model interaction. No AI tool is needed. The activity makes the token-prediction loop tangible and discussable before — or instead of — opening any software.

Core question. If a human tried to do what a language model does — guess the most likely next word, every single time, with no intent — what would that feel like? What would the output reveal?

The three roles

Role A

The Prompter

Writes a sentence stem on a card or whiteboard. Keeps it short. Does not reveal what continuation they expect.

Role B

The Model

Must say only the single most likely next word — no full sentences, no intent, no creativity. Just the statistically probable next token.

Role C

The Observer

Watches without intervening. Notes what the Model's choice reveals about genre, register, assumptions, and defaults. Shares findings in the debrief.

Step-by-step (for a Zoom call or in-person room)

Time What happens Facilitator move
0–2 min Assign roles. Three volunteers (or three breakout participants). Everyone else is a second Observer. Explain the constraint for Role B: one word only, the most statistically probable, no intent allowed.
2–5 min Prompter writes a stem: "The scientist walked into the lab and ___" Do not help Role B. Silence is fine — guessing is hard without intent.
5–10 min Role B says one word. Role A adds that word to the stem and presents a new blank. Repeat 5–8 times to build a "sentence." Point out when the output starts to feel fluent despite zero intent. Ask observers what they notice.
10–15 min Rotate roles or run a second prompt with a different genre (news headline, poem, code comment). Choose a prompt with obvious genre cues so the statistical pull is visible.
15–25 min Debrief (see prompts below). Move toward the reflection frame: human / machine / system / ethics.

Debrief prompts

Variations

Genre swap. Run the same stem in two genres — a news lead and a children's story. Compare how much the expected next word shifts.

Temperature dial. Ask Role B to try twice: once picking the word that feels most certain (low temperature), once picking something unexpected but plausible (higher temperature). Discuss how the output changes.

Collective model. Instead of one person, the whole room votes on the next word by show of hands or Zoom reaction. The most votes wins. This models the aggregation that training on many documents produces.

No-AI showcase pathway. Role B writes a model card for their own performance: what did they do well, where did they fail, what data (life experience, genre exposure) shaped their defaults?

Pathway tags

This activity is a first-class option for two pathways:

Participants who prefer not to use AI tools can complete the full session using only this activity, the debrief, and a worksheet — and their experience is no less rigorous than anyone else's.
