I know you are using your experience as an example...but I think with real poverty, you probably wouldnt know much about nutrition and neither would your parents...with enough caloric difficiency and without proper nutrition, much of the decision making/studying/long-term-planning abilities degrade quite rapidly.

That's the thing. I was pretty self-aware and I still made those choices. Imagine how much worse it is for people who don't even know what they're doing to themselves. They'll just keep pushing on ahead while their mind and body deteriorates.

Those choices are pretty hard - modern junk food has been engineered to reinforce unhealthy consumption, the US (mostly) dictates international laws around junk food restriction[1] and it's exporting the terrible free-market approach to food choice. Some of these junk foods should be heavily taxed or just outright illegal.

Also, one of the strongest predictions of working memory in all groups was gender, which may be an indicator that confounding factors haven't been broken down.

The original comment was leaping to the assumption that finding sex differences means there must be something wrong with the study/analysis. That's dangerously wrong.

“May be an indicator”. Not quite the Olympic jumping-at-conclusions performance I’d expect from a “dangerously wrong” comment.

Imagine being so poor you can't concentrate on what tomorrow is. That is what being poor does to you. It robs you of thinking.

In other words, the submission title is misleading: the effects of poverty are type of trauma. We're not talking about "too poor to afford the latest game console" here; we're talking about people who have trouble with things at the lower levels of Maslow's hierarchy of needs [0].

Is there other research indicating that males have better working memory than females?

I can't speak to specifically working memory, but there is a wide variety of research on sexual dimorphism in humans, including in cognitive function. I know there was some research showing males having better spatial memory than females. But all of this is caught up in a large nature vs nurture (vs both) question. Is it genetics that cause this? Is it the environment (social pressure/influence) that causes this? Is…

Crucially, there’s a difference between “males have statistically significantly better memory”, which is what you are talking about, and “gender is one of the top predictors of memory”, which is, reportedly, what the data in the article shows.

Leaping to conclusions about what his or her unstated assumptions must have been

If you don’t assume that the subtest scores are the same across sexes, the “qualified questioning speculation” that there is something wrong with control variables makes no sense.

How does one tease out the difference between inherent biological differences vs. differences caused by a lifetime spent in the differing social/cultural environment facing boys vs. girls?

This kind of unentanglement is usually done through twin studies: you compare how well correlated are monozygotic vs dizygotic twins. Since it’s reasonable to assume that both monozygotic and dizygotic twins share the same or at least very similar environments, if the correlation between monozygotic twins on a given trait is greater than in dizygotic twins, it means that genetic causation plays a role, while if the correlation is the same, there it is likely no genetic causation. Of course, it’s a bit hard to find monozygotic twins of different sexes, but similar ideas are used in that case.

The point is, we do have the tools to unentangle nature from nurture, and in general, all points in the direction of genetic causation when it comes to cognitive traits. I recommend reading the Jensen’s 1998 book I mentioned.

Can you explain to me what the difference is?

I've been there. Once you start thinking to yourself that there is no long term future ahead of you, the kind of choices you make becomes almost like a sick joke. Buy some fruit and vegetables to eat so that you can feel nourished and live a long life, or eat some feel good salty sugar loaded fast food because you have no fucking future anyway? Study and gain employable skills or play video games right now because yo…

>you're going to die homeless next month

Help me understand how someone could believe something along these lines for more-or-less their entire life. The fact is that poor people live long lives of many decades; they observe others around them just like them living many decades. There's nothing close to a rational reason to discount the future that hard.

How does one end up believing that every month is their last when it clearly isn't? I know people who are persistently poor act like they believe it, but I didn't think they literally consciously thought it was true.

Twin studies don’t help you with this particular question. Beyond that, there are plenty of scholars who question the common interpretation of twin studies. https://en.wikipedia.org/wiki/Twin_study#Criticism

> all points in the direction of genetic causation when it comes to cognitive traits

To be precise, some evidence points in the direction that some variation in cognitive traits is “heritable”.

It is obvious to everyone that there are substantial effects on cognitive traits due to malnutrition, disease, exposure to toxins, physical violence, persistent emotional trauma, and so on, as well as a substantial amount of variation that we currently don’t have explanations for (not to mention significant experimental noise and epistomological questions about the design and interpretation of the experiments). It is at least plausible that large-scale differences in the treatment of boys vs. girls could have effects on cognitive traits.

For example it was long thought by some people that there were inherent differences between boys’ vs. girls’ mathematical aptitude, as judged by scores on various standardized tests, but in some countries with more equal social/educational environments those differences in scores entirely disappear. A web search turns up https://insight.kellogg.northwestern.edu/article/women-and-m...

> I recommend reading the Jensen’s 1998 book

It should be mentioned that Jensen’s work has been highly controversial and has kicked off a lively debate. Some of the biggest promoters of Jensen’s work have been quite unsavory characters. Like all scholarly work (and especially all work seized on more by activists than scholars) it should be read critically and taken in the context of a wider discourse.
