English Detective #31, The Uses and Abuses of Research: Jan. 28, 2014
January 27, 2014
Your First Clue: Vocabulary Emphasized in this Issue
conduct, consensus, consent, fluke, placebo, replicate (& unreplicable.)
A few notes about the vocabulary:
To conduct is usually to lead someone, but to conduct an experiment means to do it (carry it out, or guide the research.) As a noun, ‘conduct’ is a person’s behavior—the way they act or conduct (lead) their lives.
Consensus means general agreement—often a group agreement on something without a formal vote. When you read about ‘the consensus of scientific opinion,’ it means that most scientists agree about something. It is related to the AWL word ‘consent,’ which means permission, or to agree to something.
The American legal term ‘consenting adults’ refers to two adults who agree to have sex. (‘Rape’ is when sex is forced on someone, and ‘statuary rape’ is when there is no force, but one person is considered too young to give voluntary legal consent to have sex.)
‘The consent of the governed’ is an important political doctrine expressed in the American Declaration of Independence. At the beginning of the Declaration it says that God has given certain rights that cannot be given away: “life, liberty, and the pursuit of happiness.”
It continues “That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed…”
That phrase expresses a basic principle of democracy—that government is only legitimate when the people of the country consent to it (accept it). They give that consent in order to protect those basic rights, not to surrender them.
A ‘fluke’ is an unusual, one-time, chance result— not a result you would expect or would be able to repeat. (It’s ‘unreplicable’!)
A placebo is a ‘dummy’ or ‘sugar pill.’ It has no real medicine in it, but looks like a real pill. During drug trials some participants are given the new medicine to be tested, while other participants get a placebo.
No one (neither researchers NOR participants) knows which group got the real medicine until after the test is completed. (This is called a “double-blind” experiment.) The purpose of a placebo is to test whether a medication really works, or if people just believe it works because the doctor gives it.
“The placebo effect” refers to the fact that many people will get better if they believe they are taking real medicine, even if they are actually taking a pill with no medicinal value. This power of belief is why double-blind experiments are important to get valid results.
To replicate is to reproduce—to make exact copies of the original, or to get the same results each time a test is done. So if something is unreplicable the results cannot be reproduced.
