Predicted recessions that never happened
One example is this UK Government analysis:


  "Britain’s economy would be tipped into a year-long recession, with at least 500,000 jobs lost and GDP around 3.6% lower, following a vote to leave the EU, new Treasury analysis launched today by the Prime Minister and Chancellor shows…Speaking at B&amp;Q in Eastleigh, Hampshire, the Prime Minister and Chancellor set out the Treasury’s analysis of the impact on the nation’s economy over the immediate period of two years following a vote to leave. This analysis shows that such a decision would cause an immediate and profound economic shock across the country"


But growth has been consistently positive in the almost three-year period since the vote.



I'm not sure this a very good example, because there are clear political incentives surrounding this forecast, which might mean it was less than sincere.
