headalgorithm··on Subjective and Objective Measurement of Democratic Backsliding
Abstract:

Despite the general narrative that we are in a period of global democratic decline, there have been surprisingly few empirical studies to assess whether this is systematically true. Most existing studies of backsliding rely heavily, if not entirely, on subjective indicators which rely on expert coder judgement.

We survey other more objective indicators of democracy (such as incumbent performance in elections), and find little evidence of global democratic decline over the last decade.

To explain the discrepancy between trends in subjective and objective indicators, we develop formal models that consider the role of coder bias and leaders strategically using more subtle undemocratic action.

The simplest explanation is that recent declines in average democracy scores are driven by changes in coder bias. While we cannot rule out the possibility that the world is experiencing major democratic backsliding almost exclusively in ways which require subjective judgement to detect, this claim not justified by existing evidence.

headalgorithm··on Logic programming for deliberative robotic task planning
Abstract:

Over the last decade, the use of robots in production and daily life has increased. With increasingly complex tasks and interaction in different environments including humans, robots are required a higher level of autonomy for efficient deliberation. Task planning is a key element of deliberation. It combines elementary operations into a structured plan to satisfy a prescribed goal, given specifications on the robot and the environment.

In this manuscript, we present a survey on recent advances in the application of logic programming to the problem of task planning. Logic programming offers several advantages compared to other approaches, including greater expressivity and interpretability which may aid in the development of safe and reliable robots. We analyze different planners and their suitability for specific robotic applications, based on expressivity in domain representation, computational efficiency and software implementation. In this way, we support the robotic designer in choosing the best tool for his application.

headalgorithm··on Dissociating language and thought in large language models
Abstract:

Today's large language models (LLMs) routinely generate coherent, grammatical and seemingly meaningful paragraphs of text.

This achievement has led to speculation that these networks are -- or will soon become -- "thinking machines", capable of performing tasks that require abstract knowledge and reasoning.

Here, we review the capabilities of LLMs by considering their performance on two different aspects of language use: 'formal linguistic competence', which includes knowledge of rules and patterns of a given language, and 'functional linguistic competence', a host of cognitive abilities required for language understanding and use in the real world.

Drawing on evidence from cognitive neuroscience, we show that formal competence in humans relies on specialized language processing mechanisms, whereas functional competence recruits multiple extralinguistic capacities that comprise human thought, such as formal reasoning, world knowledge, situation modeling, and social cognition.

In line with this distinction, LLMs show impressive (although imperfect) performance on tasks requiring formal linguistic competence, but fail on many tests requiring functional competence.

Based on this evidence, we argue that (1) contemporary LLMs should be taken seriously as models of formal linguistic skills; (2) models that master real-life language use would need to incorporate or develop not only a core language module, but also multiple non-language-specific cognitive capacities required for modeling thought.

Overall, a distinction between formal and functional linguistic competence helps clarify the discourse surrounding LLMs' potential and provides a path toward building models that understand and use language in human-like ways.

headalgorithm··on UK Govt Car: Tracking SIM found in sealed part imported from China
You gave up too early:

"Electronic Control Units (ECUs), which are responsible for the smooth operation of a vehicle’s engine and predominantly sought from China, are embedded with SIM cards before being sent to car manufacturers as sealed units, according to a serving security source.

The manufacturers fit the parts in cars without opening them because of various warranty and commercial agreements, the serving security source said."

And further down the page:

"How SIM cards can be used to track vehicles

SIM cards are commonplace in vehicles, installed by car manufacturers for connectivity purposes, or simply to feed back data on the performance of a car. Most cars will have at least a 2G connection. But intelligence officials warn they have created an increased vulnerability to eavesdropping from hostile states.

Most commercial trackers are essentially SIM cards attached to batteries and every geolocation tracker that sends data via a cellular network requires one. A built-in navigation system in a car with the ability to give live traffic updates will need a SIM card to connect to a signal.

However, the SIMs allegedly embedded in ECUs by Chinese companies are put there without the car manufacturers’ knowledge and appear to give the Chinese suppliers the ability to connect to the car and collect data – including where it has been, how long it has been stopped in a certain place, and even the way in which it has been driven."

headalgorithm··on Can We Prove the World Isn’t a Simulation?
If there was definitive proof that reality was indeed a simulation, and there was a creator of it, I don't think it would align with most of the world's religions.

So you would have believers and non-believers realizing what they believed in is wrong. I imagine the world would descend into chaos.

This is more difficult than wordle. You might have the correct sum but in the wrong order. For example in math 8 + 2 is the same as 2 + 8 but not in numble. The order matters.

headalgorithm··on Eradication of Diseases (2018)
From the article:

"Eradicable diseases usually need to meet the following criteria: it’s an infectious disease, humans are the major host of for the disease, effective vaccines or treatments are available for the disease, and there is political and financial support for the eradication efforts"

headalgorithm··on Can We Prove the World Isn’t a Simulation?
Totally agree. Having recently watched "Don't Look Up", I imagine there would still be a good number of "Simulation deniers" who would carry on regardless.

This sounds like the plot of a sci-fi novel...

headalgorithm··on Can We Prove the World Isn’t a Simulation?
Thanks for the well reasoned response. There are times when I think hn has become too negative, then a comment like yours pulls me back in.

"if it turned out we were in a simulation, that would almost by definition mean that our universe was intelligently designed (even if the design were merely a one-for-one replica of a non-designed universe). I think that such a scenario is unnerving to many people because it would introduce the possibility that the designer(s) might be able to express agency in the universe, and towards humans individually, in a way that the cold unfeeling laws of physics do not."

Excellent point - one I hadn't considered too deeply. I would also imagine it would challenge the ideas of religious people around the world. "Mine is the one true faith. Therefore my God(s) created the simulation" sort of thing. It would probably bring about completely new religions come to think of it.

Let's hope its not a simulation.
