Douch and Gerard's Public Commitment Technique

Douch and gerard found that by far, it was the students who had publicly recorded their initial positions who most resolutely refused to shift from those positions later. This sort of stubbornness can occur even in situations where accuracy should be more important than consistency. In one study, when six or 12 person experimental juries were deciding a close case, hung juries were significantly more frequent if the jurors had to express their opinions with a visible show of hands.
