Pessimism just sounds smarter and more plausible than optimism. Tell someone that everything will be great and they’re likely to either shrug you off or offer a skeptical eye. Tell someone they’re in danger and you have their undivided attention. If a smart person tells me they have a stock pick that’s going to rise 10-fold in the next year, I will immediately write them off as full of nonsense. If someone who’s full of nonsense tells me that a stock I own is about to collapse because it’s an accounting fraud, I will clear my calendar and listen to their every word.
