Firstly, if there’s an unspeakable danger, surely it’d be best to try and not let others be exposed, so this one’s really a question of if it’s dangerous
Not quite. It’s a question of what the probability that it’s dangerous is, what the magnitude of the effect is if so, what the cost (including goodwill and credibility) to suppressing it are, and what the cost (including psychological harm to third parties) to not suppressing it is. To make a proper judgement, you must determine all four of these, separately, and perform the expected utility computation (probabiltiy effect-if-dangerous + effect-if-not-dangerous vs cost). A sufficiently large magnitude of effect is sufficient to outweigh both* a small probability and large cost.
That’s the problem here. Some people see a small probability, round it off to 0, and see that the effect-if-not-dangerous isn’t huge, and conclude that it’s ok to talk about it, without computing the expected utility.
I tell you that I have done the computation, and that the utility of hearing, discussing, and allowing discussion of the banned topic are all negative. Furthermore, they are negative by enough orders of magnitude that I believe anyone who concludes otherwise must be either missing a piece of information vital to the computation, or have made an error in their reasoning. They remain negative even if one of the probability or the effect-if-not-dangerous is set to zero. Both missing information and miscalculation are especially likely—the former because information is not readily shared on this topic, and the latter because it is inherently confusing.
You also have to calculate what the effectiveness of your suppression is. If that effectiveness is negative, as is plausibly the case with hamhanded tactics, the rest of the calculation is moot.
Also, I believe I have information about the supposed threat. I think that there are several flaws in the supposed mechanisms, but that even if all the effects work as advertised, there is a factor which you’re not considering which makes 0 the only stable value for the effect-if-dangerous in current conditions.
I agree with you about the effect-if-not-dangerous. This is a good argument, and should be your main one, because you can largely make it without touching the third rail. That would allow an explicit, rather than a secret, policy, which would reduce the costs of supression considerably.
Some of us are okay with rejecting Pascal’s Mugging by using heuristics and injunctions, even though the expected utility calculation contradicts our choice. Why not reject the basilisk in the same way?
For what it’s worth, over the last few weeks I’ve slowly updated to considering the ban a Very Bad Thing. One of the reasons: the CEV document hasn’t changed (or even been marked dubious/obsolete), though it really should have.

You sum doesn’t seem like useful evidence. You can’t cite your sources, because that information is self-censored. Since you can’t support your argument, I am not sure why you are bothering to post it. People are supposed to think you conclusions are true—because Jim said so? Pah! Support your assertions, or drop them.

Tiny probabilities of vast utilities again?
