A report suggesting an imminent exodus of wealth from the United Kingdom received widespread sensationalised media coverage last year and influenced policy discussions, only for its authors to later abandon the central claim.
The episode offers a cautionary lesson about how misinformation can outpace truth in shaping public debate.
The wealth exodus narrative never made economic sense. Numbers of UK residents earning above £500,000 surged more than 27% over four years, a trajectory fundamentally inconsistent with large-scale capital flight.
Yet the story dominated headlines and entered policy conversation before anyone adequately tested the underlying assumptions.
UBS economist Paul Donovan, reflecting on the episode, identifies a deeper problem: the ease with which "fake news" influences policy and public opinion.
Misinformation spreads faster and further across social media than truth because it is customised to appeal to emotions, whilst factual analysis tends toward the tediously technical.
The risk here extends beyond a single discredited report. Policy decisions made under the influence of unexamined narratives can persist even after those narratives collapse. By then, regulatory changes, tax policy shifts or capital controls may have been implemented on false premises.
Donovan's conclusion is stark: economists being right is no longer sufficient. Communicating effectively has become inseparable from being correct. In an information environment where false claims travel faster than rebuttals, technical competence without persuasive communication skills leaves truth perpetually disadvantaged.
The lesson applies beyond economics. When dramatic claims capture attention and shape policy before evidence catches up, the gap between what is true and what is believed becomes dangerously wide. Fixing that gap after the fact proves far harder than establishing truth from the outset.
