In 2019, Irrsinnig Menschlich e. V. had reached more than 26,000 young people, more than 3,000 teachers and other multipliers in German schools, vocational schools, higher education, organisations and companies with its programmes. In Austria, the Czech Republic and Slovakia, 9,000 people had taken part in the programmes. The programmes "Mental, So What?" and "Mental well-being at college/university" have been evaluated several times by the Institute for Social Medicine, Occupational Health and Public Health (ISAP) at Leipzig University. They have been proven to have a preventive effect, to reduce stigma and to promote health. By reducing barriers to accessing the help and advice system, monetary costs of illness are cut substantially too. A study by McKinsey & Company and Ashoka Germany explores the economic potential of the "Mental, So What?" programme. It shows that costs are reduced by 80 billion Euro for every percentage point of ill pupils in any one year group who start an early treatment after participating in the "Mental, So What? School Day". The "Mental, So What?" prevention programme has been tested according to the strict quality guidelines of Communities That Care (CTC) and is recommended by the internationally renowned "Green List Prevention". In Germany, "Mental, So What?" is considered an exemplary mental health literacy programme. The Irrsinnig Menschlich e. V. programmes have received several awards and seals of approval:
