 Here’s an animated pair of simulations to illustrate the first effect. Here I’ve set the six doctors’ starting credences to the same, even spread in both networks: .3, .4, .5, .6, .7, and .8. I also gave them the same sequence of random data. Only the connections in the networks are different, and in this case it makes all the difference. Only the cycle learns the truth. The complete network goes dark very early, abandoning the novel treatment entirely after just 26 iterations.
