Rules:

1. Be civil


Attack the argument, not the person. No racism/sexism/bigotry. Good faith argumentation only. This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban. Do not respond to rule-breaking content; report it and move on.


2. All posts should contain a source (url) that is as reliable and unbiased as possible and must only contain one link.


Obvious biased sources will be removed at the mods’ discretion. Supporting links can be added in comments or posted separately but not to the post body. Sources may be checked for reliability using Wikipedia, MBFC, AdFontes, GroundNews, etc.


3. No bots, spam or self-promotion.


Only approved bots, which follow the guidelines for bots set by the instance, are allowed.


4. Post titles should be the same as the article used as source. Clickbait titles may be removed.


Posts which titles don’t match the source may be removed. If the site changed their headline, we may ask you to update the post title. Clickbait titles use hyperbolic language and do not accurately describe the article content. When necessary, post titles may be edited, clearly marked with [brackets], but may never be used to editorialize or comment on the content.


5. Only recent news is allowed.


Posts must be news from the most recent 30 days.


6. All posts must be news articles.


No opinion pieces, Listicles, editorials, videos, blogs, press releases, or celebrity gossip will be allowed. All posts will be judged on a case-by-case basis. Mods may use discretion to pre-approve videos or press releases from highly credible sources that provide unique, newsworthy content not available or possible in another format.


7. No duplicate posts.


If an article has already been posted, it will be removed. Different articles reporting on the same subject are permitted. If the post that matches your post is very old, we refer you to rule 5.


8. Misinformation is prohibited.


Misinformation / propaganda is strictly prohibited. Any comment or post containing or linking to misinformation will be removed. If you feel that your post has been removed in error, credible sources must be provided.


9. No link shorteners or news aggregators.


All posts must link to original article sources. You may include archival links in the post description. News aggregators such as Yahoo, Google, Hacker News, etc. should be avoided in favor of the original source link. Newswire services such as AP, Reuters, or AFP, are frequently republished and may be shared from other credible sources.

At least when I was in school, one thing that kept getting hammered home was that people had difficulty understanding graphs. That I didn't see as being an issue, not unless you're talking about something pretty exotic, but if accurate, it seems like it'd be pretty limiting. And I've seen a lot of later articles also saying that a lot of people have trouble with graph comprehension.

Last month, Alessandro Romano, Chiara Sotis, Goran Dominioni, and Sebastián Guidi surveyed 2,000 people to demonstrate that “the public do not understand logarithmic graphs used to portray COVID-19.”

They found that only 41% of participants could correctly answer basic questions about log-scaled graphs (v.s. 84% accuracy for linear-scale).

But the problem is harder than log scales. As you’ll see below, much of “the public” struggle with even the most basic charts and graphs, let alone complex visualizations.

I wish they'd had more statistics. In my high school, they had half a semester as an elective. In my university curriculum, it wasn't a core class (social science majors would study it, I would guess).

I have explained basic sampling to a ton of people on Reddit when polls came up, because they didn't believe that a sample of 1000 people out of a much larger population could result in a representative outcome. We see poll data all the time. Even if you never perform a poll, understanding the mechanism at least enough to trust it and understand when a poll might not be representative (e.g. self-selecting Internet polls). Confidence levels. I think I covered regressions in high school in an (elective) physics class, not even in a statistics class. That's a useful skill -- get a bunch of numbers, be able to produce a formula to predict more of them and get an idea of how accurate your model is. I assume that if you didn't take it or it wasn't offered, then you just wouldn't ever touch on them.
