The Question Tree

Create a dynamic talk

You prepare the questions. The audience chooses which ones get asked. With each vote, their choices trace a path through a tree.

How it works, in three steps

An interview-style talk where the audience holds the thread. Here, an imaginary interview with Marie Curie.

1

You prepare

Three themes and about twenty questions, written before the event.

2

The trunk sets the stage

The host asks the guest four questions. You can skip this step and use only the audience Q&A. It can also serve, depending on how your event is set up, to introduce round-table speakers, the different stages, and so on.

3

The audience chooses

At each stage, two questions. The room votes, yellow or blue.

The common trunk

Four questions to start together

Before any vote, the host asks the guest four questions.

They put the whole room on the same page. The guest lays out their thinking, and the audience gets into the topic.

With each question, the blue tit climbs one hollow up the trunk. Once it reaches the top, it flies off into the leaves: now it’s the audience’s turn.

The blue tit waits in the first hollow.

The vote

Yellow or blue: the room decides

Everyone gets two cards, one yellow and one blue. No phones, no app to install.

  1. Two questions appear on screen, one yellow and one blue.
  2. Everyone raises the card for the question they want to hear.
  3. The host looks at the room and confirms the majority color with a single key.
  4. The blue tit flies to the chosen olive. The guest answers.

One of the two questions stays in the same theme, the other switches. The audience decides whether to dig deeper or go somewhere else.

A vote: one yellow question and one blue question
After the vote: the chosen question appears and the blue tit sits on the olive

At the end

Each group traces its own path

After the last vote, the tree shows the path of the evening, olive by olive. The blue tit sings.

With the same tree, another audience would have taken other branches. And heard a different talk.

If there’s time left, the host draws a bonus question from the ones that weren’t asked. And a PDF keeps a record of every session.

The final board: the path of the eight votes across the three themes

A path that goes through all three themes.

Before the event

Prepare your questions ahead of time

Choose your tree, name your themes, write your questions. A preview shows each question exactly as it will be projected. You can send out a form before the talk to collect questions from the audience.

Your tree is saved in a file. You can keep it, edit it, or lend it to someone.
