You can’t outlaw something without thinking about it and even promoting it—thus, no.
However, some “counterfactual” solutions could have sense, if we know how to do this in practice; For example, if we somehow will be able to forget our birth rank, we will not be in able to identify our position in the timeline.
From causal decision theory it doesn’t make sense, as doomsday will happen or not independently of our “forgetting”. However, it looks like a classical Newcomb-like problem, where Doomsday argument is Omega, so other decision theories may recommend to try to forget the birth rank or DA.
Would it make sense to outlaw talking about doomsday argument?
