In a multi-sender Bayesian persuasion game, Gentzkow and Kamenica (2016) show that increasing the number of senders cannot decrease the amount of information revealed. They assume: (i) senders reveal information simultaneously, (ii) information can be arbitrarily correlated, and (iii) senders play pure strategies. This note constructs examples that demonstrate that adding senders can result in a loss of information if any of these assumptions is violated.
