J. Marshall Shepherd writes at CNN:
High profile legal cases like the O.J. Simpson or George Zimmerman trials have increased public understanding of “reasonable doubt.” Environmental Health News’ Peter Dykstra made a point that resonated with me. Science doesn’t operate on a “reasonable doubt” basis. If so, I suppose we would take our chances and not grab an umbrella because that 95% chance of rain is not 100%. Similarly, would most parents not take action because the pediatrician’s diagnosis has some uncertainty?
