It’s often how you say something that determines whether you get the result you want. This applies in financial services, marketing and even tax collecting.
In one experiment by the Nudge Unit they improved the payment of vehicle taxes by using simple plain language, “pay your tax or lose your car”. In fact HM Revenue & Customs attributes the recovery of an extra £210 million a year from taxpayers by using behavioural insights in its letters i.e. changing the words to influence behaviour.
