Where are your national football team players based?
A couple of facts that you might find interesting:
- Russia, England, and Italy stand out for their teams composed of players based in the same country
- 67% of players based in Russia and participating to the FIFA World Cup play for Russia, and in contrast, 18% of England- and France- based players do.
- Ghana, Cameroon, and Ivory Coast explain ca. 40% of the internationalization of France-based players
> Hey, I can find videos of people angry at about anything that exists.
Actually, you can't, and your post is a bit rediculous.
For "features of websites that are widely used", how many of them are part of youtube crying videos? Probably ~0.0001% and it certainly could be useful to call one out.
See, this is why Google wanted real names on Youtube. We've all read Youtube comments. They are the single worst comments on the Internet. Typically racist, usually mean, often obscene. Google really, through all this, just wanted to make the comments better on YouTube, I think. They heard everyone bitching and figured this was a way to make things less caustic. It didn't help, though...
I found them hilarious and often insightful expressions of honest humanity. Now, they're just shit. It's sad how much we're willing to give up to avoid every 100th comment being an aimless racial slur.
So, all this clever people working for Google thought about "making YouTube comments better" and all they came up was "kill anonymity!" and "name and shame! Time honored method to solve deviations from group think!"? Really? Oh well ..

Removing some anonymity probably removed some viciousness in turn.
Flip side: for some bizarre reason, now we see the comments of just about everyone who shares a video on Youtube and all their friends who comment. Small to medium amounts of viciousness have been replaced with an immense void of vacuousness.
I don't understand how Simpson's paradox is different from missing an explanatory variable and confusing correlation vs. partial correlation.
In Wikipedia's article header chart, what I see is the projection on a plane of a 3D problem, where the 3rd dimension has been overlooked. http://en.wikipedia.org/wiki/Simpson's_paradox
In Bob vs. Alice, I see also that the night/day flight dummy wasn't accounted for hence resulting in the so-called paradox.
It's just a special case of omitted variables with categorial variables. So instead of parameter estimates being biased up or down x amount (to the extent covariates are correlated with error terms), with Simpsons's paradox the mean effect is completely wrong due to improper grouping. This often leads to flipping signs on estimated parameters -- 'surprising' results that gets papers published.
The more complicated examples of Simpson's paradox tend to be important causes being ignored. But it's not always an issue of causality, like in the example of two Wikipedia contributors. That example doesn't really have a hidden cause, it's just the use of percentages where total articles is clearly the more useful metric.
