a quote from Orson Welles that summed up this phenomenon: “The absence of limitations is the enemy of art.”

Each vertex of the pentagon measures one aspect of a forecast:

• Logic. Does it make sense? Does it create an aha! insight?
• Complex (or Nuanced). Does it take many factors into account, avoiding a simplistic model of the world?
• Evocative. Does it cause an emotional response?
• Provocative. Does it upset, excite, and cause discomfort?
• Stimulating. Does it include implications?
