It doesn't mean that a researcher surely can achieve his/her goal and conclusion who is abided by ethics while performing research (claim) . We can take many examples of researchers who weren't able to complete their research abiding the ethics. They lack sufficient data and information regarding the research (ground) when abiding by ethics so they might have to involve themselves in ethical breach but not the one who values ethics (rebuttal) . Here, In the essay "THE FOUR-TUSKED ELEPHANT", Armand Denis had also the same situation. He couldn't extract clear and sufficient information from the people easily (warrant) . He had to bribe those people so that he could extract information and can go to the conclusion (backing) . Also, Armand had to involve himself in hunting and transportation of skull and tusk which is also against the ethics (backing) . Thus, A researcher may have to follow unethical practices to achieve the goal of research.
An Argumentative Paragraph On One Of The Issues On Mr. Know All, Following The Structure Of Argument Outlined By Toulmin
Changes in an individuals perception hardly change despite finding evidence contrary to the perception. People don't like changes as they assume that these changes might cause loss of control, uncertainty and uncomfortable in life. Even if they find out themselves wrong, they won't fluctuate towards the change. People are anxious to improve their circumstances, but are unwilling to improve themselves; they, therefore, remain bound. Here in the story "Mr. Know All", the sentence said by the narrator, "At that moment, I did not entirely dislike Mr. Kelada.", also clearly reflects that despite finding out that Max Kelada had a good heart, the narrator didn't completely change his perceptions of Kelada by the end of the story. People won't change their views even when evidence or facts are shown against that.
