To do this we must shed the veil in science. Revealing the truth; There's no diference between saying "It must be done because the bible says so" to "This is true because this book says so". To create an open mind, willing to investigate anything, we must shed the veil of shame, of tribalism, of the new cultural belief at power, science of course. I am not saying just free denialism, but with an ultimate purpose.
Sometimes, human knowledge faces a bottleneck. Usually when it must shed old believes to breaktrhough, this is when Albert Einstein made great discoveries, when he defied the laws of the absolute and found relatives in them all. Then quantum physics and so on, in every stage of human knowledge.
