To nudge or not to nudge--that is not the question.

Employers recognize that the cost of ill-health remains one open to modification. As such, well-designed health promotion programs have a place on the agenda of workplaces. Beyond awareness and education, however, sustainable and effective change in health status and related cost require changes in behaviour. With a deeper understanding of the individual, as well as the incentive (both financial and nonfinancial) that motivates him or her, achieving significant and sustained behaviour change becomes more realistic.
