  We implement full polarization tomography on the photon correlations in a
spinor exciton-polariton condensate. Our measurements reveal condensate
pseudospin mean-field dynamics spanning from stochastic switching between
linear polarization components, limit cycles, and stable fixed points, and
their intrinsic relation to the condensate photon statistics. We optically
harness the cavity birefringence, polariton interactions, and the optical
orientation of the photoexcited exciton background to engineer photon
statistics with precise control. Our results demonstrate a smooth transition
from a highly coherent to a super-thermal state of the condensate polarization
components.
