I'm not clear about the difference to the sub-components of extroversion that is e.g. automatically identified by the PCA analysis behind Big Five.

For example, extraversion is said to include such related qualities as gregariousness, assertiveness, excitement seeking, warmth, activity, and positive emotions. -- https://en.wikipedia.org/wiki/Big_Five_personality_traits

I think that this is an excellent idea. /r/lesswrong didn't really take off. I suppose there is /r/slatestarcodex, but it is useful to have this as well

I'm not sure that "interesting specifically to this community" is quite what I'm trying to point at. Taking some of my posts as examples: I want to discourage linking to things like pi.py which might be of general interest to programmers, but not of interest to this community beyond the fact that many of us are programmers. A scream of swifties is more marginal, because swifties feel kind of ingroupy. The sally-anne fallacy is totally relevant.

I'm not sure how to feel about political links.

FYI, this is the original source of that top line you're quoting: http://asofterworld.com/index.php?id=740

(the alt-text might[n't] also be noteworthy to you, which reads "Understanding is for terrorists.")

Re blocking roads: in this example If there are 9000 cars instead of 4000, the new road doesn't make any difference, and if there are more than 9000, the new road helps. With 10000 it brings commutes from 95 minutes to 90. With 20000 it brings them from 145 to 90.

And if there are 3000 cars, the original commute is 60 minutes and it remains 60; fewer than 3000, the new road is helpful.

As I understand it, this is true in general. If you add a road, it might slow things down within a certain level of demand (here, 3000-9000 cars), but outside that it will be either helpful or indifferent. Cite, but it's not open access and I don't remember how I got hold of the full paper.
