Praktikant

Florian Bochert ist Praktikant im Projekt „Upgrade Democracy“ der Bertelsmann Stiftung. Nach einem Studium der Politikwissenschaft an der Harvard Universität studiert er derzeit Internationale Beziehungen mit Fokus auf die EU an der Hertie School in Berlin. Gleichzeitig arbeitet er am Wissenschaftszentrum für Sozialforschung Berlin (WZB) in der Abteilung „Transformationen der Demokratie“.

Praktikant

Around the world, democracies are under pressure. Anti-democratic forces are fueling polarisation, contributing to radicalisation, and sowing discord through targeted disinformation campaigns. The goal: Destabilise liberal democracies and expand their own sphere of power.

Disinformation is not a new phenomenon, but new dimensions and dynamics are unfolding in digital public spheres. Disinformation campaigns cater to the functional logic of social media: The more emotional, controversial, or pointed statements are, the faster posts and comments spread across major social platforms, amplified by their algorithms, which are optimised for clicks and reactions. We observe rising numbers of users and a trend towards more and more people getting their information on social platforms, which further increases the potential damage of digital disinformation campaigns.

It is essential that we are prepared to deal with digital disinformation and that we take measures that protect and strengthen democratic, liberal processes. In a nutshell: Democracy needs an upgrade.

All of us (politics, society, media, academia), must ensure that democracy is equipped to meet the challenges of digital public spaces. At the same time, we must ensure that democratic states and their citizens also reap the opportunities that digitisation presents. Our team assesses these challenges and opportunities. In continuous exchange with experts and partners, our team assesses these challenges and opportunities. Together, we are developing constructive and innovative solutions and proposals for how to regulate platforms, how to design and create alternative, future digital spaces as well as ideas on how to hold pace with technological trends.

Practical projects

On top of our proposals, we are also implementing practical ideas. Currently, we are engaged with three practical projects:

Data Knowledge Hub

A central hub for scientists, journalists, and activists, who are keen to learn, expand, and share their skills on independtly researching social media platforms.

Faktenstark

This cooperation with the Amadeu Antonio Stiftung and codetekt is piloting a variety of activites in Saxony, geared towards raising public awareness of disinformation, supporting amplifiers in educational settings, and strengthening the media and information literacy of citizens.

Forum gegen Fakes

A large-scale, digital participation project stewarded by our colleagues at New Democracy, which aims to sensitise citizens for the impacts of disinformation at scale and to develop proposals to be considered by the German Federal Government in its Counter-Disinformation-Strategy.
