One example is building code writers deciding that since they did not feel comfortable using the centuries-old standard of building brick chimneys out to 8" thick for safe contact with wood, they would apply the "safer" number of 12" thickness, which is already in the code for the high-temperature situation around the fireplace itself. This is only "safer" if you are considering heat transfer - if you are considering the structural stability of a 4" chimney wall being built out to a greater thickness where it passes through the roof, that 12" represents a big doggone bulge way up in the sky, over my head. . (This story was originally from one of the code discussions at www.rumford.com, if you want to check the details.)

You can only justify it as an emotional, CYA decision - not a product of holistic logic
A lot of the political, regulatory, and legal discussions that affect building practices are informed by gut-level, emotional decisions about what is "safer" or "better for our economy".

These are the kind of statements that do not register with me at all since they lack technical foundation originating from the OP. Normally I would not even bother, but for the sake of topic of discussions lets take a closer look.
1. Since there are literally 1000s of codes across the globe, local, international, and combinations, please state the code you are referring to?
2.if you are considering the structural stability of a 4" chimney wall being built out to a greater thickness where it passes through the roof, that 12" represents a big doggone bulge way up in the sky, over my head
The 12" will be more structurally stable due to the aspect ratio at the ground and weight depending on soil type. I do not have all the dimension and material properties as you must have to prove the structures is unsafe and inadequate....Please post your static and dynamic analysis for review?
You can only justify it as an emotional, CYA decision - not a product of holistic logic
Because to correct your statement I cannot justify it as an emotionally based decision at all yet based on the lack of info you provided which is an issue in itself. Code is for the most part correct and proven for centuries (much of what is being referred to as historic evidence is in code) like anything it has errors, many of which are due to people that cannot understand or not qualified to understand. Ch 3 and much of code also points to it being a "minimum requirement" and many are forced to hire professionals otherwise. Some areas of code one of which you are referring to heat transfer and "braced walls" gets VERY complex and the average "layman" does not understand it or allowed to by law, that is why Architects/PE spec it out on drawing's.
Code also allows I did not see you mention to hire a PE to override it. I assume here you did not know that since it was not in your statements. Both are not a requirement in many rural areas of the world you did not mention either and this could all be a moot point to many. Many can do as they please and no legal or political jurisdictions would take the blame if the structures or heat transfers fail due to their inadequate designs.
If you want to refer to some other building as a design path you should know as a designer to once again post the specifics of that building.
If you disagree and "feel" that code is mainly incorrect please provide specific examples for review.
Disclamer: Please do not respond with any information but a pic or link to the code you are referring to and your analysis that shows your conclusions as:
A lot of the political, regulatory, and legal discussions that affect building practices are informed by gut-level, emotional decisions about what is "safer" or "better for our economy".
"A Lot" Please post all the specifics showing this and I think we should take your data to ICC and/or the local jurisdictions since this is a matter of public safety that needs to be documented and made public immediately! What shocks me here is knowing peoples lives are at risk why have you not reported your findings to homeowners, etc, and are only stating them on forums? Or perhaps you have written a letter of intent to ICC, the jurisdictions, public you are referring to?

I'd like to see a way around that since without that info in the OP there is no need to waste anymore time....you can't even talk to it or make a recommendation without the facts. There are times that the only way to communicate is by stating the facts as in this case analysis, drawings, etc, and showing exactly where the errors are. Then a peer review can occur. Some people will not be qualified to participate in the peer review unless they understand the facts. Yes that is a period!
I'm still shocked here that all these building errors that are supposedly in code are not being made aware to the jurisdictions. When people lives are at stake we should not even be discussing it on a forum. Especially when it comes to fire and structures that are deadly!

It's almost like you are on a crusade, to reform all wrongs and inacuracies in the whole world. Just by yourself. Easy on yourself, or you will do an ulcer! Chill out, calm down.
And may be a trick for you, play the dumbass. Sometimes people won't see the forrest for the trees. Often i do this, "you know, i'm not very clever", and then ask a very precise question behind.
An example, of simple but snarky. I work in the winter, for a chairlift company. Been doing that for 23 years. I've done engineering long time ago, at school. I still have some information left in my tiny brain. I run a 4 man detachable chairlift. And there's the hexagonal belts of the movement take off, which make a lot of noise. I asked all the maintenance crew what is the deflection of the belts, supposed to be. I even asked their second big boss. None of thoses morrons can answer. Like pretty much all the belts, 1cm/meter, between two contact points. Can you immagine how mad it gets me. Even worse, when the belts turn on themselves. And the worse bit is when they tell me that it is normal that these flap over 8cm, and that i understand fuck all! Just the word deflection got them confused! I started my week this morning, and they have put a brand new belt, with two old ones! When three belts working together, should be paired, with strict metrology controls.
So, yes, i can relate to what you are saying. But i still think you are taking this all too seriously.

How Permies.com Works (lots of useful links)
When I read the first part, I envisioned a chimney that starts out down in the building at 4" thick, and then gets "built out" to 12" thick where it passes through the roof (in order to satisfy code). This is why I figured it was described as a bulge. Then, when I read Terry's reply, he seems to be envisioning a chimney that is 12" thick from bottom to top, because he's saying it will be more stable. I'd love to know more about "aspect ratio at the ground." From my moderate googling skills, it seems that aspect ratio refers to the relationship between height and width, but I'm thinking there may be a building definition that is somewhat different.
Having a code that encourages the top of the chimney to be three times thicker (and more than three times as massive) as the bottom of the chimney seems a little cray-cray - less stable rather than more stable.
I think this whole exchange exemplifies some of the communication breakdowns that this thread has been trying to address. Terry cares strongly about safety (as he has stated above) and when he reads something that seems to be disparaging codes (whose raison d'etre could be said to be safety) then this pushes his buttons (OK, now I'm guessing about the buttons). This leads to a somewhat heated reply (again, I'm guessing - it "sounds" heated to me when I read it) and the original point kind of gets lost.

It's becoming apparent to me as I attempt to moderate these forums and keep discussion flowing between all kinds of people, that aspies and 'techie types', many of whom may be undiagnosed aspies, often tend to have a very different style of communication, one which many people find off-putting. There is a tendency to use complex sentence structures, longer words, sound rather too authoritative for many tastes, and write in a way that gets interpreted as 'always being right', even when the writer has no idea that their words are being interpreted like that and certainly wouldn't wish that to be the case.

It's not nice being excluded because my vocabulary is different than these specialist groups. Even if I don't think correctly - whatever that is - I feel I can understand many of these complicated ideas.
I deliberately choose not to use specialist speak and this seems to make some people feel prejudice towards me. They seem to think that I don't know the right words, therefore I don't belong to the proper club and cannot possibly understand what's going on. When in fact I do actually know the word, I just won't use them because it's exclusionary. Or at least I try not to use them in permies.
If I start talking about the coefficient of friction and the way it affects twist ratios while applying kinetic energy to scaled keratin structures, it comes across as pompous and rude (or so I'm told). But if I say string drive bands are more slippery than the rubbery ones so they require different tensions - it only sounds a little bit specialized. Perfectly fine when talking with people who share my passion. If I'm talking in a public space, like on a forum, where the reader might never have seen a spinning wheel before, level on thought about how it works - I would word it differently.
Likewise we could talk about anaerobic and aerobic bacteria or we can talk about invisible beasties - the latter is actually more accurate - when talking about making sauerkraut.
These different levels of communication don't dumb down the idea at all. Nor does it dumb down the persons involved in the conversation. We may not share the same specialist vocabulary, but we can still communicate complicated ideas with each other.
There are so many different ways of thinking, that I suspect, it's difficult for people of drastically different thought styles to find a common way to communicate with each other. I like this forum because there is so much instant feedback. I can see quickly if I've failed to get my idea across and I can learn how to improve for next time.

As a Canadian... visiting the US (not America) I found the people sounded to me "authoritative" about everything. Even though we watch the same TV and do other things with each other, a Canadian will sound more questioning than the cousin from south of the border. I have always found differences in the way people speak interesting (dialect? Accent?) and will tend to pick up an accent of the people I am with quickly.
Why do people like to be looked in the eye?
Most animals, mammals especially, it's a sign of aggression.
I've noticed not all neurotype enjoy eye contact. Some find it down right frightening. Is it a cultural adaptation?

I smile, make small talk, look in the eyes, ask pertinent personal questions and respond with empathy. On first meeting, people like me-----problem is, I really don't relate to them internally----I never learn their name----I don't recall the last conversation. To me, what sticks are ideas, principles, patterns, and solutions to problems. Try as I can to attach the people to the abstract, my brain doesn't care! I don't reciprocate gifts or phone calls; I get in trouble when I see person again and I have no idea what went on before. I'm the person in the photo with his back to the others, I'm happy by myself! I work alone just fine--sorry if it makes you uncomfortable. But if you ask for help to fix something and I'll be right beside you; so please don't hesitate to ask.
