Perfect for Climate Scientists
I propose a similar law for all climate scientists when they are presenting their computer model forecasts. Actual legislation once proposed in New Mexico:
When a psychologist or psychiatrist testifies during a defendant’s competency hearing, the psychologist or psychiatrist shall wear a cone-shaped hat that is not less than two feet tall. The surface of the hat shall be imprinted with stars and lightning bolts. Additionally, a psychologist or psychiatrist shall be required to don a white beard that is not less than 18 inches in length, and shall punctuate crucial elements of his testimony by stabbing the air with a wand. Whenever a psychologist or psychiatrist provides expert testimony regarding a defendant’s competency, the bailiff shall contemporaneously dim the courtroom lights and administer two strikes to a Chinese gong…
In the case of New Mexico, this was meant as satire and eventually was removed from the final bill, but I think it would be a great adjunct for climate forecasts, better than a surgeon general's warning.
