Spectrogram
A physical polling technique where participants position themselves along a line in the room based on their degree of agreement with a statement. One end = strongly agree, the other = strongly disagree. Similar to Constellation but specifically focused on agreement/disagreement spectrums. It makes the distribution of opinion in a group instantly and dramatically visible.
Comment l'animer
- 1
Clear floor space and identify or tape a line from one end to the other.
- 2
Label the ends: 'Strongly Agree' and 'Strongly Disagree'.
- 3
Read a statement. Participants move to position on the spectrum (30 seconds).
- 4
Once positioned, invite people at different points to explain their position (1–2 minutes).
- 5
After hearing others, ask: 'Would anyone like to move?'
- 6
Read the next statement and repeat.
Conseils
Include a few statements where the group is likely to be divided — unanimous consensus reveals nothing.
'Would anyone like to move?' after hearing others models intellectual openness without pressure.
Works with any group size if the room is large enough.
Variantes
Run seated with a show-of-hands gradient for less mobile groups. Anonymise by having everyone close eyes and walk to their position simultaneously.
