it is true. most of the problems we face are due to inappropriate communication skills. we often have something else in mind. which is causing us trouble or sterss. when we discide to talk about it,we are unable to chose the right words. that diverts the issue at hand and the focus of the conversation is shifted to something that wasnt the primary topic.
It would probably be different because an anthropologist can only know so much from artifacts and such. While the elder would know way more because they are actually indigenous and got to see and live in an indigenous group of people. Sorry if it not correct
