new citation source for reduced demand

the page says "The inverse effect, known as reduced demand, is also observed.[citation needed]" Here's a citation source, which I think backs up the idea of reduced demand for traffic. https://nacto.org/docs/usdg/disappearing_traffic_cairns.pdf — Preceding unsigned comment added by 170.173.0.16 (talk) 12:40, 16 November 2023 (UTC)

Removal of my changes to Induced Demand

[Moved from my talk page. Beyond My Ken (talk) 04:02, 20 December 2022 (UTC)]

You removed my modifications to the introduction of Induced Demand. My changes were better researched and better defended that what you restored.

What you restored claims that the term is "economic" and cites CityLab, which is not a source of economic information. It's a site used by urbanists, city planners, and such.

My changes cited a paper by Lee, Klein and Camus. It's very first sentence is "Although terms such as “induced demand” and “latent demand” have been used in transportation planning for several decades, the concept of induced demand has not been precisely defined nor has it been translated into an operational form suitable for modeling." QED, they are transportation planning terms and NOT economic terms.

Subsequent changes tried to add things to the "induced demand" page. I do not consider "film induced demand" to be a valid term. Google has only 8 hits for the phrase.

I consider "supplier induced demand" (or "physician induced demand") to be a separate term. In transportation, the shift in the demand-curve is cause indirectly by an increase in supply. In "supplier induced demand", that is not the case. Another argument is that the writing of "supplier induced demand" is often "supplier-induced demand" and not "supplier induced-demand". It is a very different term.

Please respond or restore my changes. — Preceding unsigned comment added by Mdnahas (talk • contribs) 03:57, 20 December 2022 (UTC)

I did not remove that material you added, it's still in the article. And since that material was about the use of the phrase in economics, I restored that part of the lede that you removed.

What "you consider" is interesting, but not relevant. The material I restored was sourced, whatever you think of it.

BTW this is not the place for this discussion. I'm moving it to the article take page. Beyond My Ken (talk)

[end of moved material]

User:Beyond My Ken I disagree that the introduction that I changed was "sourced". There is a difference between having a citation and being sourced. Having a citation doesn't matter if the statements on Wikipedia have nothing to do with the materials cited.

The first citation was a City Lab article that never mentions that the terms are related to economics. That article only addresses traffic.

The other citation was a Wired article that states "... induced demand, which is economist-speak for when increasing the supply of something (like roads) makes people want that thing even more." It is not at all clear that that definition matches the text in the introductory paragraph.

I would not consider either citation a "source" for the intro paragraph that you restored.

Moreover, I believe this journal article is a better source than pop-sci websites like Wired and CityLab. It clearly states that the phrases were in use by transportation workers before proper economics came into the picture. It should be the source cited by the introduction.

Lastly, what "I consider" is relevant. I have a Masters in Economics from UT-Austin, a top 25 university. I have expert opinion on what is the same and what is different in the realm of economics.

Criticism section: undue emphasis on single source

Hi all, I've tagged the 'Criticism' section with {'{One source|section|date=October 2023}}, since its only references are two essays by the same author, Steven Polzin. Perhaps this could be upgraded to {'{Content}}. 67.71.197.70 (talk) 00:23, 21 October 2023 (UTC)

Thanks for the improvement advice - many more references to other credentialed authors making the exact same points added as references. More can be added at will. -- 85.220.29.158 (talk) 20:07, 18 November 2023 (UTC)

I removed the long list of Steven Polzin's arguments again. There is no compelling reason offered for why this one person's arguments ought to be reproduced in detail in this article. I also added a {{what}} tag to WSP, whatever that is. Our WSP disambiguation page tells me it might refer to the Washington State Patrol, which is the local police force for the US state of Washington, but it is unclear. These edits just sort of assumed we're all supposed to know what WSP is, as if it is self-evidently an authority on this topic. Einsof (talk) 02:01, 19 November 2023 (UTC)

Lead paragraph

@User:Beyond My Ken, can you please explain what was wrong with the recently amended lead paragraph? — HTGS (talk) 03:48, 21 November 2023 (UTC)

Actually, since you wish to make changes, why don't you tell us in what way the status quo lede needs to change, and in what way your edits improve it? Recall that the WP:ONUS is on the editor who wishes to make changes. Beyond My Ken (talk) 04:08, 21 November 2023 (UTC)

@Beyond My Ken: – related to latent demand and generated demand – in the first sentence is a poor way of introducing those concepts, especially as those titles redirect to this article. It would be useful to the reader to define them properly early on. — HTGS (talk) 04:12, 21 November 2023 (UTC)

@Beyond My Ken: It is also useful to introduce the domain of the subject early, so instead of the awkward sentence at the end of the paragraph, (This is consistent with the economic model of supply and demand) we can give the relevant contextual domain in the first sentence. — HTGS (talk) 04:16, 21 November 2023 (UTC)

@Beyond My Ken: You might be a little confused about WP:ONUS though. It refers to the need for verification, and of course there is onus on editors to support their claims, but the claims I introduced are easily verifiable by the sourcing already in the article. — HTGS (talk) 04:19, 21 November 2023 (UTC)

Get a consensus, otherwise, leave the article as is. Beyond My Ken (talk) 10:28, 21 November 2023 (UTC)

@Beyond My Ken Do you have any specific concerns with the changes made, or how I have outlined them above? — HTGS (talk) 22:54, 21 November 2023 (UTC)

Yes, they are not better than the existing text, and therefore do not improve the article. They appear to me to be making changes for the sake of making changes. Get a consensus if you want to institute your changes. Beyond My Ken (talk) 00:48, 22 November 2023 (UTC)
