Can’t altruistic rationalists who want to be right as individuals, and want the group to be right more than they want to be known to be right avoid information cascades? All they have to do is form their own private opinion, and even if they are swayed toward the majority opinion by the evidence of the other rationalists’ opinions, pretend to be contrarians, because of the consequences that will have for the rest of the group (providing them more information)? Or at least say something like “I accept the majority opinion because the majority accepts it and they are unlikely to be wrong, but here are some arguments against that opinion I came up with anyway?”
