A raised hand is a bid with the number scrubbed out.

§ 1 · The problem

Moderation is allocation, done blind.

Every discussion runs on one scarce resource — the time available for speaking — and whoever allocates it cannot see what they need to: not how urgent each point is, not what it would add, not how one hand compares with the hand two seats over. A raised hand transmits about one bit. So the moderator guesses, and the guesswork has favourites: confidence reads as urgency, familiarity reads as relevance, the seat on the aisle catches the eye.

The point that mattered most may sit behind the hand that never gets picked — and the room never finds out what it didn't hear.

§ 2 · The idea

Let the bid be real.

The twenty-dollar thought was right about everything except the dollars, because a market in dollars listens to whoever has the most. So Palaver issues its own currency: everyone starts every discussion with the same balance — 20 points, unless the room decides otherwise — and points buy speaking time from the people you are speaking with, and nothing else. They reset when the hour ends. You cannot arrive rich, and hoarding buys nothing. Urgency is the only wealth.

§ 3 · Rule one — against discovering the price by interrupting

You see your place before you commit.

A bid buys a position in a queue everyone can read. If the price is high and your point can wait, wait — the price is telling you something true about the room. Ties go to whoever asked first, so matching the leader does not overtake them.

§ 3 · Rule two — against rewarding the calculating

The winner pays the runner-up's price.

Second-price, by default: win the floor and you are charged the next-highest bid, not your own. Honesty is the safe strategy — bid what the turn is genuinely worth to you, and you will only ever pay what it took to win.

§ 3 · Rule three — against holding forth

The floor is metered by the minute.

A winning bid is a rate, not a fee. End your turn early and you are charged for the time you used, not the time you feared you'd need. Brevity, for once, is worth something to the person being brief.

§ 3 · Rule four — against dead air

Breaking a silence is free.

A pure auction has a dead-air failure mode, and Palaver inverts it. While nobody is waiting the price of the floor is zero, so the screen stops asking for a number and offers one button instead. A silence breaker is never charged, even with nothing left to spend — and a room can reward them with a share of whatever bidding their contribution provokes. It is a liquidity subsidy for a conversation.

§ 5 · The ledger

A transcript records who spoke. The ledger records who wanted to.

A bid is a valuation somebody paid to express, and it outlasts the hour. Two students sit silent through the same seminar: one bid four times and never won the floor, the other never bid at all. From the front of the room they are identical. They need close to opposite responses.

The instructor's screens say no more than the ledger knows — "has not held the floor" is a fact, "disengaged" would be a guess — and each room's own short survey can tell a comfortable silence from an uncomfortable one, which nothing else in a classroom can.

§ 6 · The doors

Run one tonight.

Palaver is free. Nothing to install, nothing to configure, and only the person who presses the button needs a Google account. For a course, sign in at app.palaverbeta.com and create a room — a roster, a join code, the auction rules yours to set, and the term's ledger kept week over week.

Afterword · where this goes

The idea is bigger than the instrument.

Speaking time is scarce; scarce things get allocated whether or not anyone admits it; and a room that can see what its members' turns are worth to them runs a better conversation than a room allocating blind. Anywhere people take turns talking is somewhere this applies — seminars and Q&As, reading groups, department meetings, the dinner table. If you run discussions, run one on a market — it takes a QR code — and see what it tells you.
