Former good article nomineeDysgenics was a Natural sciences good articles nominee, but did not meet the good article criteria at the time. There may be suggestions below for improving the article. Once these issues have been addressed, the article can be renominated. Editors may also seek a reassessment of the decision if they believe there was a mistake.

Choice of main term; narrow vs broad claims

[edit]

Dysgenics is the decrease in prevalence of traits...

This opening seems to imply, in WP:WIKIVOICE, that an overall decline is occurring:

  • By using the definite article the, and
  • By invoking reification bias: the tendency to believe that a phenomenon is real if it has been given a name.

I'm not aware of an overall genetic-based decline being established for any trait of interest, and indeed the rest of the article does not treat the implied claim as true.

One possible solution is to lead with the adjective form and narrower claims:

A policy or practice is described as dysgenic if it causes a decrease in prevalence of traits...

For example, a war that kills millions of drafted soldiers might be dysgenic for health if ...

Another possibility is (B) distancing the broad claim using a term that suggests uncertainty:

The dysgenic hypothesis states that humans populations are undergoing a decrease in prevalence of traits...

Proponents of the hypothesis argue that certain societal trends may affect the selection pressures on heritable traits: ...

These could be combined, with each term bolded and defined at a different point in the article.

We should also take care to not imply that several narrow claims automatically add up to the broad claim. The three examples in the article (draftee fatalities and health; fertility and intelligence; neonatal care and genetic disorders) relate to different traits and are far from the only factors influencing the gene pool.

First of all, you're using pretty stylish talk quotes, not bad.
Feel free to make it more ambiguous, but I will supplement the article with some 50 sources to the opposite effect in the next days or weeks, so the effort may be moot in the end. Biohistorian15 (talk) 16:23, 4 July 2024 (UTC)[reply]
In any case, I would find "dysgenic hypothesis" objectionable. If e.g. tall people are likely to be drafted, this entails a Darwinian selection against this trait. The real question would be if there are additional variables that may counter-act this kind of dysgenics (relative to some frame). Biohistorian15 (talk) 19:44, 4 July 2024 (UTC)[reply]
I would like to correct my previous statement: extensive Wikihounding has made it unlikely that I'll engage with this topic to the extent I originally wanted at this time (or ever). So, just ignore that half of the comments above. Biohistorian15 (talk) 09:41, 25 July 2024 (UTC)[reply]

Neutral title

[edit]

After reading Kevin Bird's recent paper, I'm thinking "Dysgenic pressure" or "Dysgenic predictions" would be a better title than "Dysgenics". Any comments before I start a move discussion? (Including a preference between the two suggestions.) Jruderman (talk) 22:24, 12 August 2024 (UTC)[reply]

New source: Sear and Townsend 2023

[edit]

There's a decent source (Sear and Townsend 2023) that might be included in article. I also added one quote. 51.6.193.169 (talk) — Preceding undated comment added 13:15, 7 July 2024 (UTC)[reply]

More explanation for last paragraph?

[edit]

The Niesser source says: "There is no convincing evidence that any dysgenic trend exists. . . . It turns out, counterintuitively, that differential birth rates (for groups scoring high and low on a trait) do not necessarily produce changes in the population mean." I don't have access to the source, but IF the source talks about the reason for population means not changing has to do with regression towards the mean, (which I thought was a well-observed phenomenon in genetics, though I could be wrong) it would be nice to add this explanation to the sentence sourced to Niesser, because I'm the type of person who thinks the encyclopedia is better if people understand WHY some phenomenon is true. ---Avatar317(talk) 03:53, 25 July 2024 (UTC)[reply]

I was able to access the book a few weeks ago using The Wikipedia Library, and you may be able to as well. It's in the APA section.
IIRC, I looked at chapters 13–15 because their titles seemed relevant to the question of dysgenics. One point, directly related to the text quoted in our footnote, immediately made sense to me: looking only at the highest decile and the lowest decile means you're throwing away information about the shape of the graph – and most people are somewhere in the middle! (To add my own synthesis: consider an imaginary country where poor people are having kids and gaining just enough in welfare benefits to stay afloat, rich parents are hiring au pairs, and middle-class couples feel that the escalating costs of housing and childcare will force them to reduce their quality-of-life if they choose to have more children. You'll have some kind of J-shaped curve but you'll be trying to reason based on the slope between the ends.)
Coincidentally, I just did a major revamp of Gini_coefficient#Limitations, much of which is about throwing away information about the shape of a graph.
There was a lot more in Niesser that I didn't understand on first read, which is why I didn't summarize it for the article. Maybe I'll go back sometime, but right now I'm extremely busy trying to shepherd a move discussion related to recent IT outages.

"I'm the type of person who thinks the encyclopedia is better if people understand WHY some phenomenon is true."
YES. This is why I advocate for including primary sources in addition to secondary sources. The Niesser-edited volume may actually serve as both – each chapter is essentially a paper by a different author (a primary source), while its inclusion in the book and its summary in the opening supports both notability and interpretation (a secondary source). Jruderman (talk) 04:41, 25 July 2024 (UTC)[reply]
True. I added a "clarification needed" tag that was then immediately removed multiple times over by user:Generalrelative. I don't really understand Niesser's argument either though... Biohistorian15 (talk) 09:44, 25 July 2024 (UTC)[reply]
