# Experts reveal truthfully (<math>s^{i}(\theta)=\theta=(m^{i}_{1},m^{i}_{2})</math>).
# R only believes <math>(m_{1}^{i},m_{2}^{2})</math>. Meaning: He believes the report of expert 1 on one dimension, and the report of expert 2 on the other dimension.
* ==Rui's closing comments ;)==* Slight change in assumptions leads to different answers. * "Degrees of freedom": More dimensions allows more revelation? * Is this robust? People saying no: # Levy and Razin: Study Battaglini model with noise. Think about it this way: Crawford/Sobel show no 1 dimension, 1 sender, no full revelation. Battaglini shows: 2 dims, 2 senders, full revelation. Levy and Razin show: 2 dims, 2 senders, no full revelation. # Ambrose and Takahashi: 2 senders, 2 dimensions plus constraints on choice space -- answer is no full revelation.
