So the nice Catalonians have declared independence and the nasty Spaniards have revoked regional autonomy. Both sides now have to try to make their ideas into reality, ideally without doing too much damage to the real world in the process.
Is a 2009 post by Paul Graham. I read his Hackers and Painters in 2008 and recommended it then. I return to him via johnlawrenceaspden but I don't want to go down that road now; instead, I want to look at the identity post:any mention of religion on an online forum degenerates into a religious argument... people don't feel they need to have any particular expertise to have opinions about it. All they need is strongly held beliefs, and anyone can have those. No thread about Javascript will grow as fast as one about religion, because people feel they have to be over some threshold of expertise to post comments about that. But on religion everyone's an expert... Politics, like religion, is a topic where there's no threshold of expertise for expressing an opinion.And - as I'm sure I've bemoaned in the past - you could add global warming to the list. PG continues with some of the obvious explanations for why those topics end up like this:
they deal with questions that have no definite answers, so there's no back pressure on people's opinions. Since no one can be proven wrong, every opinion is equally valid, and sensing this, everyone lets fly with theirs.And one could include GW by replacing "definite" with "currently well-known from observation". But this doesn't quite satisfy him, since he observes the obvious, that other issues with unclear answers don't end up such a mess. Instead, he offers:
they become part of people's identity, and people can never have a fruitful argument about something that's part of their identity. By definition they're partisan... you can have a fruitful discussion about a topic only if it doesn't engage the identities of any of the participants. What makes politics and religion such minefields is that they engage so many people's identities.I think that's correct; or at least part of the correct answer. PG deduces from this that:
If people can't think clearly about anything that has become part of their identity, then all other things being equal, the best plan is to let as few things into your identity as possible.Because if you do that, you'll be able to think clearly about as many things as possible. Do you see where this is going now? Oh, good. Just in case you don't, I refer you to stuff like Rejecting Climate Change: Not Science Denial, but Regulation Phobia? where I've been criticising "my own side" and getting nothing but grief for it. To be fair, I've probably forgotten why I thought it was a good idea, but the PG post provides part of the answer: I'm complaining about people who have gone off and let too much GW into their identity.

Gosh, how exciting! A little while ago I noticed several posts and twits about ocean heat content, which I ignored, because it is dull. But now it turns out to be exciting, because someone has stolen RP Sr's idea! (archive, since the Peilke's do not have a stellar record on keeping blogs going). Well, you can read RP Jr for his opinion (I found this via Retraction Watch).
Rejecting Climate Change: Not Science Denial, but Regulation Phobia is a paper by Professor Edward L. Rubin of the Vanderbilt University Law School. Is he respectable? I don't know. I come to this from an article in the Graun recommended by Bart, who is normally sensible. When I came to read the abstract I recognised it, but as something that I hadn't felt inclined to finish when I first saw it. So now I'll try a bit harder.
