Liars/hallucinators

As chronicled in your researcher's journal as I researched my history of early lifestyles in South Asia...


Why do some archaeologists -- very few -- lie about their "finds"? It makes me ignore all of their writings, because I don't want to repeat potential fabrications. It would be much more useful if they must indulge their religious or whatever leanings if they just admitted they're speculating and have fun with that, but meanwhile clearly present the actual facts. Perhaps like a few sad people I've met around the world, some of them hallucinate so much they don't realize they're presenting fiction.
