The following appeared in an article written by Dr. Karp, an anthropologist.
"Twenty years ago, Dr. Field, a noted anthropologist, visited the island of Tertia and concluded from his observations that children in Tertia were reared by an entire village rather than by their own biological parents. However, my recent interviews with children living in the group of islands that includes Tertia show that these children spend much more time talking about their biological parents than about other adults in the village. This research of mine proves that Dr. Field's conclusion about Tertian village culture is invalid and thus that the observation-centered approach to studying cultures is invalid as well. The interview-centered method that my team of graduate students is currently using in Tertia will establish a much more accurate understanding of child-rearing traditions there and in other island cultures."
Write a response in which you discuss what specific evidence is needed to evaluate the argument and explain how the evidence would weaken or strengthen the argument.
Argument: Dr.field conclusion is invalid
Observation method is invalid
Interview centered method will get accurate info about child rearing there and in other islands.
Evidence:
My research( correct conclution? Interview centered methed is accurate? )
Dr . field method( wrong conclution? Observation method is invalid?)
The author concluded that dr .field’s conclusion about tertia culture is invalid and thus the observation-centered approach to study culture is invalid as well, in interview-centered method that his team of graduate students is currently using in teria will establish a much more accurate understanding of child-rearing traditions there and in other island cultures. He supported his argument based on evidence that dr. field used observation-method 20 years ago in tertia for studying child-rearing and concluded child were raised by all people in village instead of parents. And another evidence was his team used interview method for a group of village including tertia showed that child talk about their biological parents more than other adults. However, merely given these two evidences the author’s argument is invalid and incredible.
First he argued Dr.field conclusion is invalid and his conclusion is valid based on evidence that his team used interview method and found children talked more about their biological parents. It is not convincing enough because this evidence cannot prove children are raised by their biological parents. If he want to prove this point he also needs to provide exact evidence about how children got interviewed and prove that they were not given misguided question, also that children explicitly indicate they were raised by biological parents. Perhaps those children just were payed more attention by their biological parents but still raised by all people in village. Lacking of further evidence we cannot conclude that children was raised by their biological parents. Furthermore we cannot conclude that dr.field was wrong and his observation method is invalid. We also cannot conclude that interview method is accurate because we don’t know how children were interviewed and how many of them were interviewed.
Even the conclusion of author is true regarding children rearing, only based on evidence that dr.field used observation 10 years ago is also not enough to justify that observation method is invalid. Perhaps it was long time ago and the village had other method to raise the children and dr. field’s conclusion was correct at that time. Or perhaps dr. field conclusion is wrong, but it does not necessarily mean that the observation is invalid. Maybe dr. field used it wrongly and it cannot indicate this method is questionable. However we also need to know other evidence about how observation method lead to wrong conclusion in other studies by different people, otherwise we cannot conclude that this method is invalid.
No matter whose method is correct or wrong, based on the evidence given in the article it is impossible to conclude that interview method should be used to further study tertia child rearing culture and we will need further evidence about the details of author’s study and dr. field’s study. Furthermore, we also need to know the evidence of other people’s study about this issue on tertia island to determine what method is valid to do the research.
