perceptual/observational—observational evidence cannot provide a common basis for theory comparison, since perceptual experience is theory-dependent
Kuhn expresses or builds on the idea that participants in different disciplinary matrices will see the world differently by claiming that their worlds are different
(source: Staford Ecyclopedia of Phylosophy on Thomas Kuhn, Ch. "4.2 Perception, Observational Incommensurability, and World-Change")
For observational incommensurability depends on working into different disciplinary matrices and seeing world differently, and consequently on practicing in different worlds, are we legitimate to argue that perceptual / observational incommensurability is an ontological incommensurability as well?
Or what is the connection between the two (observational and ontological incommensurability)?
