Does the 2-group split stay even if you continue the simulation until all answers have been revealed?
Good question—no; revelation of answers eventually causes convergence into 1 group.
If you increase the standard deviation of p[i] so there are more very right and very wrong guessers, do they tend to split more into right and wrong groups? I expect they would.
Good question—no; revelation of answers eventually causes convergence into 1 group.
It makes the splitting happen faster.
