You're getting downvoted, but I think for Wikipedia you're correct. Wikipedia's purpose is not to be a cutting-edge repository of all truth. It's to conveniently organize all the knowledge that can be looked up. That's because every bit of it needs to be verifiable by non-expert editors. If there's some knowledge that can't be looked up, then that's not Wikipedia's problem to solve.
Indeed. And even more in general, "truth" is a realtive term. More often than not, it is hardly verifiable, the best thing available is "consensus", which is the aim of Wikipedia content.
