Why do people check the weather so many times before a trip?
People seek certainty even when certainty changes nothing.
The forecast changed yesterday.\n\nIt may change tomorrow.\n\nStill, people refresh the app again.\n\nThe hidden mechanism is uncertainty reduction.\n\nHumans prefer predictable problems over unpredictable possibilities.\n\nRain can be planned for.\n\nUncertainty cannot.\n\nThe weather report rarely changes reality.\n\nBut it changes how reality feels.\n\nPeople think they check forecasts for information.\n\nVery often, they check them for emotional stability.
