Real change does not happen overnight. It is built through grounded, systematic, and sustained work. In a monitoring framework published by the World Health Organization, the need to institutionalize and mainstream behavioral science across public health systems is clearly articulated. WHO emphasizes embedding behavioral science into policy engagements, research projects, and capacity-building efforts. To truly bring about institutional change in the way people think, decide, and act, insights must be translated into interventions, programs, and systems that work in the real world.
