The Need for Science-Based Organization

Some time shortly after the invention of the graphical Internet, it became ripely apparent that humanity was fucking itself with its own technology and was on the fast path toward societal morbidity. We maximized energy extraction without perfecting clean use, accelerated manufacturing technologies and global supply chains without developing socioeconomic models to cope with the disruptions, and modified life itself without having any perspective on what modifications would actually, in the ...

 Political Detox - Why Political Discussions Become Disres...

For one week, political stories are off-topic. Please flag them. Please also flag political threads on non-political stories. For our part, we'll kill such stories and threads when we see them. Then we'll watch together to see what happens. Why? Political conflicts cause harm here. The values of Hacker News are intellectual curiosity and thoughtful conversation. Those things are lost when political emotions seize control. Our values are fragile—they're like plants that get forgotten, then ...

 Teaching as Natural Selection

Teaching is commonly associated with instruction, yet in evolution, immunology, and neuroscience, instructional theories are largely defunct. We propose a co-immunity theory of teaching, where attempts by a teacher to alter student neuronal structure to accommodate cultural ideas and practices is sort of a reverse to the function of the immune system, which exists to preserve the physical self, while teaching episodes are designed to alter the mental self. This is a theory of teaching that ...

 Instruction vs. Selection

The main difference between an instructional system and a selectional system is that the instructional system uses information from the environment to change the properties of the object in question, but a selectional system has a large and varied population of objects, and the ones that are most fit for the environment are differentially reproduced. Hopefully an example Edelman uses from immunology will help clear this up. The theory prevailing before the present one was called the theory ...

 Borg Weaknesses

Memetic Infection One of the most worrying weaknesses is the spread of virulent information patterns such as memes. Memes thrive in environments with intense communication (Bjarneskans et al. 1997), and would likely spread extremely quickly inside a borganism, infecting both collective and unit schemata. Having a working system for memetic defence appears to be vital for the well-being of a borganism, especially in the face of memes similar to computer viruses (in the cybernetic environment ...

 Lessons from the Real Paleo Diet

And the answer is, ‘yes.’ I think there’s three main lessons we can learn: First, there’s no one correct diet, but diversity is the key. So, depending on where you live, you can eat very different things, but you need diversity. We lack the ability to synthesize many nutrients that we require for life, nutrients and vitamins, and we are required to get them from our foods. Eating a diet that’s rich in species, has high species diversity is very important. Now unfortunately in Ameri...

 Reasons to Give Up News

News misleads. News leads us to walk around with the completely wrong risk map in our heads. So terrorism is over-rated. Chronic stress is under-rated. The collapse of Lehman Brothers is overrated. Fiscal irresponsibility is under-rated. Astronauts are over-rated. Nurses are under-rated. News is irrelevant. Out of the approximately 10,000 news stories you have read in the last 12 months, name one that – because you consumed it – allowed you to make a better decision about a serious matter...

 The Immune System

An immune system of enormous complexity is present in all vertebrate animals. When we place a population of lymphocytes from such an animal in appropriate tissue culture fluid, and when we add an antigen, the lymphocytes will produce specific antibody molecules, in the absense of any nerve cells. I find it astonishing that the immune system embodies a degree of complexity which suggests some more or less superficial though striking analogies with human language, and that this cognitive system...

 The Immune System Reaction and Overreaction

The body has a very ingenious and usually effective system of natural defence against parasites, called the immune system. The immune system is so complicated that it would take a whole book to explain it. Briefly, when it senses a dangerous parasite the body is mobilized to produce special cells, which are carried by the blood into battle like a kind of army, tailor-made to attack the particular parasites concerned. Usually the immune system wins, and the person recovers. After that, the imm...

 The Importance of Touch on Infants

Touch plays a very special role in the life of young babies. Because it is so well developed at birth, it provides these brand-new arrivals more detailed access to their fascinating new world than any other sense. Touch is obviously essential to babies' sensory-motor development, but it also has a surprisingly potent influence over their physical growth, emotional well-being, cognitive potential, and even their overall health, because of some fascinating effects on their immune function.
