Situation: False Consensus
"I think we all agree here."
The team comes to some agreement (on direction or approach, for example) but doesn’t really understand the underlying assumptions or the downstream implications. If they understood those, they might not agree.
The effect: A false consensus may move the project forward, leading to more challenging conflicts later when the underlying assumptions come to light.
The challenge: Since everyone agrees, it may be difficult to detect that this is a problem.
