The Trouble With The Ten Commandments
In a 5-to-4 per curiam decision, the Court ruled that the Kentucky law violated the first part of the test established in Lemon v. Kurtzman, and thus violated the Establishment Clause of the Constitution. The Court found that the requirement that the Ten Commandments be posted "had no secular legislative purpose" and was "plainly religious in nature." The Court noted that the Commandments did not confine themselves to arguably secular matters (such as murder, stealing, etc.), but rather concerned matters such as the worship of God and the observance of the Sabbath Day.
1. I am the Lord your God, who brought you out of Egypt, out of the land of slavery. You shall have no other gods before me.
2. You shall not make for yourself an image in the form of anything in heaven above or on the earth beneath or in the waters below. You shall not bow down to them or worship them; for I, the Lord your God, am a jealous God, punishing the children for the sin of the parents to the third and fourth generation of those who hate me, but showing love to a thousand generations of those who love me and keep my commandments.
3. You shall not misuse the name of the Lord your God, for the Lord will not hold anyone guiltless who misuses his name.
4. Remember the Sabbath day by keeping it holy. Six days you shall labor and do all your work, but the seventh day is a sabbath to the Lord your God. On it you shall not do any work, neither you, nor your son or daughter, nor your male or female servant, nor your animals, nor any foreigner residing in your towns. For in six days the Lord made the heavens and the earth, the sea, and all that is in them, but he rested on the seventh day. Therefore, the Lord blessed the Sabbath day and made it holy.
5. Honor your father and your mother, so that you may live long in the land the Lord your God is giving you.
6. You shall not murder.
7. You shall not commit adultery.
8. You shall not steal.
See the 6th Commandment.
9. You shall not give false testimony against your neighbor.
10. You shall not covet your neighbor’s house. You shall not covet your neighbor’s wife, or his male or female servant, his ox or donkey, or anything that belongs to your neighbor.

Uncontested Primaries
Colorado's non-Presidential primary elections are today. Many are uncontested.
There were 242 potential primary races related to 121 elected offices. There are 205 uncontested primary races and 34 contested primary races (14% of the number of possible contested primaries).
In part, there are few primary contests because in Colorado, the caucus process narrows access to the primary ballot. One can petition onto the primary ballot, but only if one either doesn't utilize the caucus process or uses it and doesn't fair too poorly there.
In 4 of the contested primaries, no one is running in the other party so the general election winner will be decided today. There are 26 races with only one candidate running from both parties that have already been decided. Of course, there are far more races that have both Democratic and Republican candidates, but which one party or other other is almost sure to win in November, including both contested Democratic Party U.S. House primaries.
There is also one U.S. House vacancy race, in CO-4, which is effectively a general election and has one candidate from each major party and two independents running. Greg Lopez, the Republican candidate, is almost sure to win that race for the remaining five months of the current term, but will not be running for re-election in the fall as he is not running in the GOP primary for that seat.
There are more details below the fold.

The Ambivalence To Extremism Pipeline In Politically Polarized Contexts
Political extremism varies across people and contexts, but which beliefs will a person support through extreme actions?
We propose that ambivalent attitudes, despite reducing normative political actions like voting, increase support for extreme political actions.
We demonstrate this hypothesized reversal using dozens of measures across six studies (N = 13,055). The effect was robust to relevant covariates and numerous methodological variations and was magnified when people’s attitudinal or ideological positions were more polarized.
It appears to occur because being conflicted about political issues can feel psychologically uncomfortable, making extreme actions more appealing. Notably, this emerged when people thought ambivalence was justified, whereas leading them to consider ambivalence unjustified suppressed the effect, suggesting that ambivalent people are coping with but not necessarily trying to reduce their ambivalence. These results highlight the interplay of affective and cognitive influences in extreme behavior, showing that beliefs people feel justifiably conflicted about can promote extremism.

Juneteenth
Juneteenth, celebrated today on June 19, is now a federal, state, and local holiday.
It memorializes the several days in 1865 when many slaves in the Confederacy were made aware from Union forces that they had been freed by Abraham Lincoln's Emancipation Proclamation. Until then, that proclamation had been largely an empty promise.
This was a monumental and profoundly life changing event for almost every slave who received the news. But it is a complex memory, because it was also only one huge and critical step in the very long process that still isn't complete. It was an absolutely necessary step, but it wasn't a sufficient one to chance society enough to do justice to those who heard it by itself.
Reparations, in the popular imagination, forty acres and a mule, never materialized. Reconstruction was short lived, and was followed by about ninety years of lynchings, discrimination, and Jim Crow. Many freed slaves continued to do work similar to what they had done while they were slaves, but while migrating from one plantation to another as they saw fit, rather than being bound to a master. Their economic well being improved, but more incrementally than dramatically. Their path to education and business ownership and gaining the skills to be competitive in the economy was winding with one step back for every two steps forward.
A parity of legal rights on paper finally started to be achieved in the 1950s and 1960s, but it took decades longer for even those legal rights to be anywhere close to being fully realized. And, even then, having legal rights, and being able to use them in a way the secured the descendants of the freed slaves who heard the news in the Juneteenth days of 1865 something approaching parity in social and economic well being has taken longer than that. In 2024, we still aren't all of the way to Martin Luther King, Jr.'s promised land.
So, Juneteenth is an important day, but was not a moment of a singular victory whose benefits were reaped right away. It was a beginning and we haven't made it to the end yet.
Detecting Aircraft
The U.S., at least, is pretty good at developing anti-radar technology to help the stealth aspect of its aircraft. But this has limits, because there are other ways one can detect aircraft:
1. Visual spotting on the ground with a good communications network that can tell people where an aircraft is heading.
2. Visually identifying the aircraft with satellites or very high altitude aircraft.
3. Locating the aircraft based upon the noise it makes. This could be automated, a bit like systems the identify the location of firearm discharges automatically by triangulating the source of the sound from multiple listening devices. One could have a whole national network of noise localizing devices tuned to detect aircraft.
4. Locating the aircraft based upon heat or other aspects of its jet emissions such as chemical signatures or contrails that it might leave.
5. Covertly monitoring takeoff locations and guessing at where the aircraft might be heading, taking into account its range and any fuel drop tanks it is carrying.
6. Getting spies or electronic bugs or using signals intelligence to learn from commanders or lower level personnel where the aircraft are headed and when.
7. Covertly planting tracking chips on aircraft, or personnel or cargo or bombs and missiles on the aircraft which are hard for the force using the aircraft to locate.
Frustrated With Biden
Military Quick Hits
* The assumption that a large scale amphibious assault in a hostile entry, like the D-Day invasion, remains an important capability of the U.S. military, is unfounded. There hasn't been a significant amphibious assault anywhere in the world since the Korean War in the 1950s. What country would the U.S. invade that way? China? North Korea? Russia? Iran? It is hard to come up with plausible scenarios to motivate the need for this capability.
* Republicans in Congress are pro-disinformation. The U.S. Defense Department shamefully spread anti-vax disinformation about Chinese vaccines during the COVID epidemic.
* The U.S. Air Force isn't sure if it will move forward on building a "Next Generation Air Dominance" warplane, basically a successor to the F-22 and F-35. There is speculation that this may be driven by dissatisfaction with Boeing and Lockheed Martin, the only domestic defense contractors capable of building such a plan. Cost and viable alternatives are also factors:
Paying for this next-gen fighter, which is expected to cost about $300 million a pop, will be tough as the service expects to spend increasing amounts of money in the coming years on F-35s, the new B-21 Raider, and the next-gen Sentinel intercontinental ballistic missile. And in addition to budget constraints, new technology developments and drones have the service rethinking the future of air dominance.NGAD may be the only place the Air Force can take a reduction, said Bryan Clark, a senior fellow at the Hudson Institute, given all the other programs the Air Force needs to pay for, and the desire to grow its new collaborative combat aircraft program.The service also may be rethinking its overall concept of operations to rely on B-21, CCAs, and stand-off weapons [i.e. long range missiles] rather than a traditional aircraft, Clark said. But given emerging technologies, it’s still unclear what air dominance is exactly going to look like in the future.
The collaborative combat aircraft program, sometimes called the "loyal wingman" program, is a drone aircraft that supports a manned jet fighter.
Guns v. Knives
Officers shot and killed a woman who was holding a large, hunting-style knife at an intersection in downtown Denver on Sunday, police said.Officers used a Taser on the woman twice but she began advancing toward them as they tried to back up from her, Denver police Chief Ron Thomas said a news conference near the scene. Three officers fired at her, he said.The shooting will be investigated and the results will be sent to prosecutors to decide if the shooting was lawful, he said.“My belief is that the officers perceived a significant threat and responded to that threat,” Thomas said.The shooting happened near Triangle Park at the intersection of Lawrence Street and Broadway. Thomas said a Denver Park Ranger was among the first to call and report the woman was in the intersection around 11:45 a.m. Sunday.

ChatGPT Is Bullshit
Unlike blockchains, artificial intelligence software has great potential. But it isn't quite ready for prime time yet.
Recently, there has been considerable interest in large language models: machine learning systems which produce humanlike text and dialogue. Applications of these systems have been plagued by persistent inaccuracies in their output; these are often called “AI hallucinations”. We argue that these falsehoods, and the overall activity of large language models, is better understood as bullshit in the sense explored by Frankfurt (On Bullshit, Princeton, 2005): the models are in an important way indifferent to the truth of their outputs.We distinguish two ways in which the models can be said to be bullshitters, and argue that they clearly meet at least one of these definitions. We further argue that describing AI misrepresentations as bullshit is both a more useful and more accurate way of predicting and discussing the behaviour of these systems.
Extremes Meet
The MAGA right (I started calling it the "far right" but when it makes up maybe 30-40% of the voting public, how "far" is that?) is almost always absurdly wrong.
But part of the reason that what should be an easy Presidential race in 2024 is because the left can fall into some troubling traps:
* A congenital inability to acknowledge good news in the economy. If the stock market is doing well, who cares about the well being of rich stockholders? If wages are up, who cares because prices are high (even if wages are rising faster than inflation). If unemployment is low, there must be other measures of it that aren't as good. The economy is extremely healthy right now, and while indeed, there are inequalities in the American economy and we have lots of billionaires, this is still a good thing for everyone, even the "bottom 30%."
* The patently false assertion that there is no difference between the Democrats and the Republicans. Yes, at the national level, there is gridlock, and until that ends only bipartisan policies can be adopted. But there is a huge difference between the parties and is shows up in state policy, in regulations, in foreign policy, in appointments including judicial appointments, and in the budgets and legislative efforts that do get proposed. This nihilism plays into the hands of people who oppose everything that they believe in and are trying to make the world worse.
* The failure to recognize that Israel is not just a puppet whom the U.S. President controls. The U.S. has some influence over Israel as a long time and important ally that provides it with a variety of kinds of aid that have helped it prevent its utter annihilation at the hands of hostile regional neighbors. But it has its own internal politics that are firmly in control of its policies.
* Allowing the best to be the enemy of the good. The standard against change should be measured is whether it makes the status quo better, not whether it is perfect in a utopian sense. In a democracy with divided control, perfect is rarely an option.
* An unwillingness to recognize that the lesser of two evils is the best that any democracy can offer. I didn't support Biden in the primaries in 2020 and argued strenuously that he wasn't the best choice. He won that election by less than a percentage point in the marginal state, and we can't know how other candidates would have done. I strongly favored having Biden not run again and leave the democrats with an open race to choose someone new. That didn't happen either. But that doesn't mean that Biden isn't profoundly better than Trump. Biden isn't a felon. Biden doesn't lie every time he opens his mouth. Biden understands how the government and the world work. Biden isn't openly hateful. Biden isn't trying to speed up climate change. Biden isn't coddling the rich to nearly the same extent.
* The false belief that essentially all sources of reliable information are corrupt and can't be trusted.
Politics is the art of the possible. Too many on the left don't recognize that and don't recognize that they don't have the political support necessary to make their vision happen overnight.
There are also select policy issues where left wing sentiment is well-intentioned but misguided:
* Opposition to nuclear power. It is cleaner and safer the opponents realize and the waste disposal issues are political rather than technical in nature.
* Opposition to marriage by minors, even when those minors are already in a relationship with someone and have children with them. In countries where there is no divorce or where minors are pushed into relationships that are imposed upon them this is a real problem. But the U.S. has no-fault divorce, and marriage empowers wives, rather than weakening them, by giving them more rights.
* Opposition to corporations when the real concern is with some other economic reality that really has nothing to do with the corporate form.
* Support for local businesses and independent businesses, when often those businesses are sometimes less efficient, and meet people's needs less well.
* Support for local family farms, when our very way of life is made possible by long distance trade in food stuffs and agricultural products, and when small family farms are an order of magnitude or two less productive per acre than larger farms. These farms are also often highly polluting and less safe.
* Support for AMTRAK even though it is mostly a dinosaur that is getting in the way of progress and needs absurdly high subsidies on most of its routes because the quality of the service it provides is so poor.
* The false belief that standardized tests are more racially biased and social class biased than other forms of evaluating students seeking to go to college.
* Afro-centrists who believe that, historically, Egyptians and the Moors were mostly sub-Saharan African in appearance.

U.S. Navy Cruisers v. Destroyers v. Frigates
The CG(X) program was announced on 1 November 2001. An initial requirement for 18 CG(X) was raised to 19 under the plan for a 313-ship Navy in 2005.A reassessment in 2007 suggested splitting the CG(X) into two classes, fourteen Zumwalt-sized "escort cruisers" and five 23,000 ton ballistic missile defense ships. There was political pressure for some or all of these ships to be nuclear powered.The fiscal year (FY)2009 budget called for procurement of the first CG(X) in 2011, and the second in 2013. On 1 February 2010, U.S. President Barack Obama unveiled his proposed budget for FY2011. This budget called for, among other things, canceling the entire CG(X) program.The program was cancelled in the 2010 Quadrennial Defense Review. The CG(X)'s mission will instead be performed by DDG-51 Flight III destroyers, after the U.S. Navy concluded that the ships could rely on off-board and space-based sensors and so did not need a radar bigger than the DDG could carry.
The ongoing DDG(X) program is looking for a post-Zumwalt replacement for the Arleigh Burke class guided missile destroyer. It optimistically targets a 2032 date to have the first member of this class built. Concepts for the DDG(X) imagine a hull and size and level of automation similar to the Zumwalt, and similar offensive and defensive weapons suites and a powerful laser weapon to use as an active defense system. But no specific design has been developed. The ability to reload the Vertical Launch system at sea is another capability that is currently being discussed as urgent for new ships and as a retrofit for older ships with these missiles.
Littoral combat ships can be specialized with modules, some of which are just beginning to enter service, for light surface warfare, anti-submarine warfare, naval mine countermeasures, light amphibious warfare unit support, and anti-smuggling roles. But none of these missions has been very successful or received a warm reception from the Navy. Instead, the U.S. Navy has largely abandoned the idea of having specialized surface warships (apart from aircraft carriers, amphibious transports for Marine units, and hospital ships). The U.S. Navy has also largely abandoned the mission of having ships well equipped to provide fire support for Marines or other troops in coastal operations (a role that the Zumwalt class has been supposed to fill).
The U.S. Navy is not even actively developing a modern counterpart to the battleship, a large, heavy surface warship with as many naval guns that are as heavy as possible as it could manage, and heavy hull armor. Battleships haven't been used in warfare since 1991, when they provided naval support fire for troops in the Gulf War, and left U.S. Navy service in 2010. There are no battleships in service anywhere in the world, although Russia's one solitary Kirov class battle cruiser comes close (Russia also has two somewhat smaller cruisers and one Kirov class ship in the dockyard being refurbished).
Indeed, only a small number of world navies have any ships above the frigate class.
For example, only a few ships are viewed as cruisers today except by the U.S., which is decommissioning them, and the Russian Navy, which has three in active service. The Italian Navy has an aircraft carrier that it calls a cruiser and while "the Type 055 of the Chinese Navy is classified as a cruiser by the U.S. Department of Defense, the Chinese consider it a guided-missile destroyer."
