“What does scientific forecasting tell us about global temperatures over the next century?”
The science of forecasting is complex. After 50 years spent studying the issue, I have found there is plenty of experimental evidence that in complex, uncertain situations, experts cannot forecast better than those with little expertise. In 1980, MIT Technology Review published my “Seer-sucker Theory”: “No matter how much evidence exists that seers do not exist, suckers will pay for the existence of seers.” Since 1980, research has provided more evidence for this surprising theory, especially Philip Tetlock’s 2005 book, “Expert Political Judgment.”
