Your "tribe" did not and does not have complete information therefore your "tribe" was unable to pass complete information on to you. The tribe cannot give you knowledge it does not have. In order to gain new knowledge, you'll have to leave the tribe. Most people do not do this. Tribal grounds are familiar and known. Leaving the familiar and known elevates anxiety levels. Anxiety based fears paralyze many into a state of arrested development. People feel vulnerable when exploring. When exploring concepts, it would be wise to first armor yourself with robust discernment like math, science (particularly computer science), philosophy, logic, logical fallacies, debate, and argumentation. Leaving the tribe to bring back "the medicine" is noble but bear in mind that most, if not all, members of the tribe will demonize you for having left in the first place. Some may become jealous of your courage to venture out beyond the known and, seeking to soothe their bruised egos, may throw shade at you. Others will find other reasons to slight you, often falsely justified by ridiculous rationales. They were afraid to leave the tribe. Perhaps you were too but you did it anyways: an act of courage. This type of cold shoulder welcome is to be expected. As they say, a prophet is without honor in his own home.
