The Rhetoric Approach, Postmodernism, and Pluralism - The Rhetoric Approach

14 important questions on The Rhetoric Approach, Postmodernism, and Pluralism - The Rhetoric Approach

What is the rhetoric approach?

An approach that confers science as being primarily about persuasion, and studies scientists tool of persuasion (influencing to do so)
= Conversation analysis
- Traditional concern: forms and methods of arguments and communication
- Mostly formed by economists about economists

What does the rhetoric approach explore?

1. How ideas, arguments and results are distributed (seminars, journals, textbooks etc)

2. How scientists try to persuade their colleagues
- Arguments from authority (acknowledgements from big names) signaling
- Advanced mathematics and statistics
- Stories: intuitive justifications of models which lends credibility (analogies, standard stories)
vb: lemon market
- Methaphor: figurative concepts that convey rich associations
vb: invisible hand (Adam Smith)

What is the lemon market?

Buyers don't know the difference between lemons and peaches. So the average is the price, but the sellers of the peaches do not want to sell their car for that price. So in the end only lemons are being sold

= approximation of a car market, to keep it simple and to make the message clear (with adverse selection)

What is the Diamond coconut model?

Everybody on the island has a coconut tree. The taboe is that people cannot eat their own coconuts. So a trade in needed
1. Good equilibrium: everybody knows that there is enough opportunity to get coconuts
2. Bad equlibrium: nobody climbs in the tree to get the coconuts. Everybody thinks this way, no trade no consumption

= coordination failure, self fulfilling prophecy

What is the contemporary rhetoric approach?

Similar but now it also applies to the practices of science.
- Describes the focus and modern vocabulary

Main concern: the dialogues between economists and scientists

What are the three dimensions of classical rhetoric?

1. Logos (word): the internal consistency of the message (logic behind the reasons and effecitvenss of the claim)

2. Pathos (experience): the appeal to the audience's emotions, sympathies and imagination

3. Ethos (character): the trustworthiness or credibility of the writer or speaker

Which dimension is used by scientists according to positivists?

Logos (objective)

How does the approach build on the SSK and the ESK?

Builds on the SSK and the ESK, to examine the way which economics and science influence each other

Adds a psychological aspect

What is the classical rhetoric concept of persuasion?

1. The rhetoric approach considers the social framework of a scientific community in terms of how it disseminates (distributes) its ideas and arguments.
vb: scientific journals and papers (sharing ideas)

2. The rhetoric approach considers how individual economists or scientists are persuaded within the framework of those structures of communication that are relied upon by a scientific community
vb: readers of papers are more likely to be influenced if the writer is famous

Who was Deirdre McCloskey?

Developed the rhetorical approach: how do ecomomists reason? How do they persuade each other

What were the two aims of the work of Deirdre McCloskey?

1. She wants economic methodologists to pay closer attention to the ways in which economists actually reason and seek to persuade one another of their views. This includes considering their use of mathematics and statistics

2. She wants to advance a clear critique of positivsm that she sees as dominating economists' understanding of science and proper method in economics

What is small m and big M methodologies?


Economists are story-tellers: via models to be convincing
Argued that small m methodology is better than big m

- Big M: developed by philosophers of science (who usually don't know a lot about economics) "a good scientist acts this way"
- Small m: basic insights in how economics is actually practiced and some rough practical guidelines (describe) "how stories are made convincing"

How does small M methodology work?

Knowledge does not have foundations, because it changes according to how economists succeed in persuading each other (knowledge can be lost)


Pluralism: the meaning of words and concepts often depend on the context and may change over time
vb: social welfare

Economics is a conversation, so they need to keep conversation civilized

Why are interviews with economics useful?

Interviews may yield important insights in how economic research take place
