Post-truth refers to circumstances where appeals to emotion and personal belief have greater influence over public opinion than objective facts. It occurs when news reports lack substantial factual evidence and instead gratify social and emotional needs by providing alternative viewpoints. Politicians like Nigel Farage have contributed to a post-truth environment by making demonstrably false claims, such as promising that £350 million per week spent on EU membership would go to the NHS if the UK left, and later admitting it was a mistake. Technology has disrupted truth by allowing audiences to consume media that supports their preexisting views rather than objective facts, and trust sources like Farage that provide emotionally gratifying viewpoints over substantiated reporting.
