The strong interaction still provides mysteries to us, like the generation of mass and the fact that the most elementary particles --quarks and gluons-- cannot be directly observed. Measuring so-called baryonic resonances to shed light on these 40-years old problems, is a large-scale experimental effort at the Jefferson National Accelerator Facility (JLab). An overview of present and future JLab activities will be given, focused on the question of how to connect observations to theory. In particular, first results and their analysis from the Frozen Spin Target (FroST) Lab will be discussed.

Conclusive answers in baryon spectroscopy are a long-sought goal. Necessary steps towards this goal will be discussed, such as statistical criteria, the need for hadron beams, and the need for a suitable amplitude parameterization to make the connection to (ab-initio) lattice QCD approaches. The material will be presented for a broader audience.
