Information does not originate in the mind. It does not pop there from no where, suddenly appear to be broadcast by the owner of the mind.
Information is a set of observations of the physical world. The Brain analyses different bits of observations and tries to make sense of them. The ability to compile things you have seen, and then work out a possible meaning of it, is where knowledge comes from. If other people hear that knowledge, and agree with the reasoning behind the idea, then it will become accepted and repeated.
Over time though, new observations will mean that an old accepted idea my have to change, due to the new data.
