Policy-making shapes everything from public services to digital environments, yet policies often emerge from political pressure, intuition, or crisis response rather than systematic analysis. Impact assessments and evidence-based approaches attempt to reverse that pattern by grounding decisions in data, research, and careful evaluation of real-world consequences.

When done well, they improve the quality of decisions, reduce unintended harm, and strengthen public trust. When done poorly — or skipped entirely — policies can become disconnected from the realities they aim to address.
