  2. Evaluation & Impact

    Know what changed, for whom, and whether it was worth it.

    “Did it change outcomes? For whom, and why? What should we keep, fix or stop?”

    • A credible estimate of impact, and who benefited
    • Why it worked or did not, with clear recommendations
    • A report built to satisfy funders, auditors and the European Commission

Network

Behavioural Insights for Policy Greece Network

With the ETERON Institute, we bring Behavioural Insights for Policy to Greece: a network that takes behavioural public policy beyond the countries where it is already established, connecting researchers, public servants and practitioners.

Its first Greek workshop, in Athens on 26 and 27 February 2026, featured keynotes from Professor Ralph Hertwig (Max Planck Institute for Human Development) and Eva Koromilas (OECD Observatory of Public Sector Innovation).

The network meets again in 2027: dates to be announced.
