    1. The theme I find most interesting here is ontology as a system of relations between felt senses, and metaphysics as the relation between this network of felt-senses and the world.

      synchronicity and harmonization between inner body systems #[[integrated systems]]

    2. At any rate, if CSHW can be used to build a good quantitative model of human-human interactions, it might also be possible to replicate these dynamics in human-computer interactions. This could take a weak form, such as building computer systems with a similar-enough interactional syntax to humans that some people could reach entrainment with it; affective computing done right.

    1. Types of Structure Outliners take advantage of what may be the most primitive of relationships, probably the first one you learned as an infant: in. Things can be in or contained by other things; alternatively, things can be superior to other things in a pecking order. Whatever the cognitive mechanics, trees/hierarchies are a preferred way of structuring things. But it is not the only way. Computer users also encounter: links, relationships, attributes, spatial/tabular arrangements, and metaphoric content. Links are what we know from the Web, but they can be so much more. The simplest ones are a sort of ad hoc spaghetti connecting pieces of text to text containers (like Web pages), but we will see many interesting kinds that have names, programs attached, and even work two-way. Relationships are what databases do, most easily imagined as “is-a” statements which are simple types of rules: Ted is a supervisor, supervisors are employees, all employees have employee numbers. Attributes are adjectives or tags that help characterize or locate things. Finder labels and playlists are good examples of these. Spatial/tabular arrangements are obvious: the very existence of the personal computer sprang from the power of the spreadsheet. Metaphors are a complex and powerful technique of inheriting structure from something familiar. The Mac desktop is a good example. Photoshop is another, where all the common tools had a darkroom tool or technique as their predecessor.

      Structuring Information

      Ted Goranson holds that there are only a couple of ways to structure information.

      In — Possibly the most primitive of relationships. Things can be in other things and things can be superior to other things.

      Links —Links are what we know from the web, but these types of links or only one implementation. There are others, like bi-directional linking.

      Relationships — This is what we typically use databases for and is most easily conceived as "is-a" statements.

      Attributes — Adjectives or tags that help characterize or locate things.

      Metaphors — A technique for inheriting structure from something familiar.

    1. wealth persist across racial groups.

      EXAMINE THE SYSTEMS WHICH HELP TO ENFORCE THIS RACIAL INCOME DIVIDE! Most relate. Fixing these systems could help to bridge the income gap between racial groups. Even laws so ingrained in us.

    1. Sometimes, systems just scale the problemA UI design system is more than the code of a component library. It’s more than the colors, styles, and margins of your elements. It’s an ever-growing and ever-evolving creature that entails your brand and your user’s feelings.

      If you don't understand the problem - you can [[scale the problem instead of solve the problem]], and it's important to remember that a [[design system is more than a component library]]

    1. Instead of publishing a single one-size-fits package for components, we create an ecosystem where everyone works together yet deliver independently. The design system’s team role is to facilitate and regulate, not block or enforce.

      I think this is a really important point - the design system's team is to facilitate, not gatekeep.

    2. What you see here is a page composed of shared components. However, these are independent components developed and owned by different teams and published from different projects, which are mixed and integrated together.

      the move towards single page applications, component centric frameworks, etc has shifted how we view building webpages.

      It is not so much that we are building a page, but we are building components that we assemble into a page.

      We’re not designing pages, we’re designing systems of components.—Stephen Hay via atomic design

    3. The design of your system is not ready until you have two assets:a) A style-guide that defines the styling and implementation of your UI. This is usually a rather long document with a lot of text and typography.b) A set of reusable visual elements that bring together both visual (UI) and functional (UX) consistency through components. This is usually a rather large canvas with elements drawn on Figma or Sketch etc (we use both).

      there are two [[primary assets of a design system[[

      • the style guide
      • the reusable elements - an implementation of the style guide
    4. The benefits of our system go way beyond UI/UX consistency. We greatly accelerated and scaled our development, improved our product quality, and greatly improved work between developers, designers, and everyone else.

      Design systems enable faster development and delivery, and help teams scale - and have value beyond UI/UX consistency.

    1. The real heart of the matter of selection, however, goes deeper than a lag in the adoption of mechanisms by libraries, or a lack of development of devices for their use. Our ineptitude in getting at the record is largely caused by the artificiality of systems of indexing. When data of any sort are placed in storage, they are filed alphabetically or numerically, and information is found (when it is) by tracing it down from subclass to subclass. It can be in only one place, unless duplicates are used; one has to have rules as to which path will locate it, and the rules are cumbersome. Having found one item, moreover, one has to emerge from the system and re-enter on a new path.

      Bush emphasises the importance of retrieval in the storage of information. He talks about technical limitations, but in this paragraph he stresses that retrieval is made more difficult by the "artificiality of systems of indexing", in other words, our default file-cabinet metaphor for storing information.

      Information in such a hierarchical architecture is found by descending down into the hierarchy, and back up again. Moreover, the information we're looking for can only be in one place at a time (unless we introduce duplicates).

      Having found our item of interest, we need to ascend back up the hierarchy to make our next descent.

    1. Linux Memory Management at Scale

      "we had to build a complete and compliant operating system in order to perform resource control reliably"

      epic real-talk. the only people on the planet who seemed to have tamed linux for workloads. controlling memory. taming io. being on the bleeding edge, it turns out, is almost entirely about forward-progress. what can we reclaim?

      • oomd for memory protection
      • fbtax2
      • psi monitoring for io regulation
      • cgroups v2

    1. You have no choice. You can shop at a store that pays its workers better, sure, but the real atrocities have taken place long before your desired products have reached the shelf, and the stickers have nothing to do with it. “And here grocery has one last trick,” Lorr writes: “it allows us to hate our shrimp and eat it too. The image of the bad polluting aquaculture farmer or vulnerable exploited migrant gets imprinted in our first-world brain, while the fungibility of commodity goods—that maze of brokers and agents—gives the entire system the plausible deniability it craves.”

      Systemic change is hard. But it is the most effective tool for the job. Where are the levers and where can we stand? Who has the power and motive to make these changes?

    2. Trucking is now an industry thriving on its workers’ vulnerability

      Again, as with most other parts of the supply chain previously mentioned.

    3. boycotting a single product is pointless. “Look at what happens when abused children get pushed out of labor markets. They typically don’t suddenly find better jobs. They get pushed further underground,” he says. “What you in the West have to realize is the entire narrative is backwards. In trafficking, the media focuses on why and where poor people get into difficult situations. But maybe we should be looking at why they are poor to begin with?” The answer is, of course, the “hunger behind our hunger.”

      And now we're back to systemic problems, and how to fix them.

    1. Successful long-lived open systems owe their success to building decades-long micro-communities around extensions/plugins, also known as a marketplace.

      This could be said of most early web standards like HTML as well...

    1. See it as an experiment where failure yields valuable insights 🔬.

      Try and figure out when you actually are the most productive. When your usage of tools actually works. The insight you gain there could help you figure out what your ideal "productivity situation" is.

      Side note, just realized this is a perfect application of cybernetics (at least as far as I understand it so far).

      1. Apply a system
      2. Observe myself within that system
      3. Gain feedback by observing how I behave in that system
      4. Use that feedback to tweak that system until I've achieved my desired goal
    2. Time management is more about a system that works and less about a tool or just a method

      I've been focusing on the wrong things. To do lists aren't going to help me manage my time more effectively. It's a tool through which a system needs to be applied. If I don't have the right system, no tool is going to work.

    1. Over the coming years, we will work with local and national governments in these processes seeking to radically alter their dominant way of thinking and working and to experimentally develop new distributed models of non-linear systemic governance

      👍on the practical engagement with policy.

      Still not really sure what some of the terms mean e.g. what would "distributed models of non-linear systemic governance" look like

      More generally, i need a clearer sense of what linear vs non-linear (systems) approaches involve. (e.g. don't command and control systems still involve feedback loops etc?)

      I also think i'd like his definition of systems (vs non-system) thinking. I see the term used a lot and i have a sense of this from e.g. Senge or (more precisely) in Commons' MHC "systematic" level.

    1. A final word: when we do not understand something, it does not look like there is anything to be understood at all - it just looks like random noise. Just because it looks like noise does not mean there is no hidden structure.

      Excellent statement! Could this be the guiding principle of the current big data boom in biology?

How about: Us teachers and other stakeholders need to engage in dialogue/action around equity and NGSS in our own local connections yet be aware of and engage with other local dialogues and furthermore transform/be-transformed-by the emerging, higher level discourse. np

    1. The Two Sides of the H-LAM/T System

      When I view this diagram, I am reminded of Robert Rosen's Modeling Relation, an image of which is here The Modeling Relation grew out of research in Relational Biology which was the first mathematical biology to recognize that relations among organism components and between those components and the environment are key to understanding complex adaptive systems.

    2. It is the augmentation means that serve to break down a large problem in such a way that the human being can walk through it with his little steps, and it is the structure or organization of these little steps or actions that we discuss as process hierarchies.

      As I begin to read this (as I did back in 2000 when I was introduced to Doug) I begin to think in terms of reductionism as a practice in the face of problems which are highly complex, nonlinear, and which do not submit to chunking.

    1. For large-scale software systems, Van Roy believes we need to embrace a self-sufficient style of system design in which systems become self-configuring, healing, adapting, etc.. The system has components as first class entities (specified by closures), that can be manipulated through higher-order programming. Components communicate through message-passing. Named state and transactions support system configuration and maintenance. On top of this, the system itself should be designed as a set of interlocking feedback loops.

      This is aimed at System Design, from a distributed systems perspective.

    1. In my opinion if you can get enrolled into a degree program for systems biology then that would be best. However, if you are just exploring the field on your own I would recommend going through these resources.Video lectures by Uri AlonVideo Lectures by Jeff GorePrinciples of Synthetic Biology (at edx)Coursera specialization on systems biology.If you are looking for mathematical intensive start with first 2 and if you are looking for biologically intensive begin with last 2. Either way go through all 4 of them as they provide diverse perspective on systems biology which is very important. As you will move through these materials all the necessary supplementary information like books, papers and softwares will be informed within these materials itself.Hope this helps!
    1. Our extensions also have implications for theories ontrust.

      Bookmarked section for later consideration of proposal studies on how time interacts with trust in time- and safety-critical social coordination.

    2. Therefore, training should focus on learning how toquickly recognize volunteers’ volition in participating inan emergent group, the tasks they might engage in, andthe support they might need to carry out those tasks.Such training could also help people to recognize thebenefits and dangers of generalized trust. It could alsohelp people to quickly evolve a coordination mecha-nism that does not rely on what people know, but oncompiling and communicating a narrative of the actionsthat volunteers take, so that others are able to assess forthemselves what actions they could take to help.

      Majchrzak et al continue to suggest that emergent response training could reconceptualize a new role for emergency management professionals, aside from the default coordination/management. Further, they suggest that citizens could be trained to participate.

    3. ur examination suggests that by expandingthe context in which TMS theory is applied to includeemergent response groups, insights can be gained intotheir internal dynamics. The three indicators of the levelof development of a TMS provide a useful frameworkfor organizing these insights in the exhibit.

    4. The urgency of time may make it too onerous forthe extra effort of articulating actions as they are beingperformed, yet most emergency response requires somecommunication.

      Interaction of time (tempo/pace) and breakdowns in articulation work.

    5. Explicitly articulated narratives mayalso make clearer that multiple sequences of actions maybe occurring simultaneously, thus resolving role conflictsby allowing multiple ways to accomplish a task

      Evokes Schmidt and Bannon's articulation work in CSCW.

    6. Emergent response groups may also use a mechanismof creating a community narrative (Boland and Tenkasi1995), which is a running narrative of the actions takenand not taken, the decisions made, and the theories inuse. Narratives do not represent a single shared under-standing of a domain; rather they represent the mul-tiplicity of events and actions a community is taking,as members are taking them. Narratives may be articu-lated explicitly or understood implicitly.

      SBTF after-action report, as an example. But who is the audience for this narrative?

    7. Whenemergent response groups first come together, membersare likely not to ask one another about who knows what;instead, they are likely to ask about what is knownabout the situation and about the actions taken thus far(Dyer and Shafer 2003, Hale et al. 2005). The cogni-tive structure that they develop for the group centersnot around people, but on action-based scenarios thateither have been or might be carried out. These scenariosinclude decisions, actions, knowledge, events, and feed-back (Vera and Crossan 2005).

      Suggested extensions for TMS theory:

      "1. Tailor the Role of Expertise"

      "2. "Replacing Credibility in Expertise with Trust Through Action"

      "3. "Coordinating Knowledge Processes Without a Shared Metastructure"

    8. On the surface, the lack of sta-ble membership suggests that a shared mental modelmay not be viable or even desired in emergent responsegroups. Time may be too precious to seek consensus onevents and actions, and agreements may make the groupless flexible to accommodate to changing inputs.

      Evokes pluritemporal concerns about tempo, pace and synchronization.

    9. hus, we believe challenges occur in all three indica-tors of the level of development of a TMS—expertisespecialization, credibility, and expertise coordination—requiring a need to consider extending theorizing abouteach indicator for emergent response groups.

      Ways to extend TMS to emergent groups:

      "1. Reconceptualize the Role of Expertise Specialization as a Basis for Task Assignment"

      "2. Assessing Credibility in Emergent Response Groups"

      "3. Expertise Coordination in Emergent Response Groups"

      These extensions evoke boundary objects and invisibility

    10. Moreland and Argote(2003) suggest that the dynamic conditions under whichthese groups form and work together are likely to havenegative effects on the development of transactive mem-ory.

      Are there workflow or technology breakdowns that could help ameliorate the negative effects?

    11. Research on TMS has identified three indicators of thelevel of development of a TMS (Lewis 2003, Morelandand Argote 2003):1.Memory (or expertise) specialization:the tendencyfor groups to delegate responsibility and to specialize indifferent aspects of the task;2.Credibility:beliefs about the reliability of mem-bers’ expertise; and3.Task (or expertise) coordination:the ability of teammembers to coordinate their work efficiently based ontheir knowledge of who knows what in the group.The greater the presence of each indicator, the more de-veloped the TMS and the more valuable the TMS is forefficiently coordinating the actions of group members.

      Three indicators of the level of sophistication of the system:

      • Memory specialization (think trauma/hospital care CSCW studies)

      • Credibility

      • Task coordination

    12. A TMS can be thoughtof as a network of interconnected individual memorysystems and the transfer of knowledge among them(Wegner 1995). Individuals who are part of a TMSassume responsibility for different knowledge domains,and rely on one another to access each other’s expertiseacross domains. Expertise is defined in the TMS litera-ture to broadly include the know-what, know-how, andknow-why of a knowledge domain (Quinn et al. 1996),what Blackler (1995) refers to as embodied competen-cies. Expertise specialization, then, reduces the cognitiveload of each individual and the amount of redundantknowledge in the group, while collectively providingthe dyad or group access to a larger pool of knowl-edge. What makes transactive memory transactive arethe communications (called transactions) among individ-uals that make possible the codifying, storing, retrieving,and updating of information from individual memorysystems. For transactive memory to function effectively,individuals must have a shared conceptualization of whoknows what in the group.

      Majchrzak et al describe how TMS is oeprationalized as a network.

    13. TMS theory, a theoryof group-level cognition, explains how people in collec-tives learn, store, use, and coordinate their knowledge toaccomplish individual, group, and organizational goals.It is a theory about how people in relationships, groups,and organizations learn who knows what, and use thatknowledge to decide who will do what, resulting in moreefficient and effective individual and collective perfor-mance.

      Definition of transactive memory systems theory -- used in org studies to understand how knowledge is coordinated among groups.

    1. Davis and col-leagues (3) provide useful new data that enhance our un-derstanding of the effects of hospitalists on health sys-tems. In their study of a voluntary hospitalist system at alarge rural nonteaching hospital in Mississippi, theyfound that patients cared for by hospitalists had adjustedhospital stays that were 25% shorter, and costs that were12% less, than patients cared for by nonhospitalist inter-nists. For patients in the highest severity group, these sav-ings were even greater. Annualized, the authors extrapo-late that the hospitalists would have saved $2.5 millionhad they cared for all of the internists’ patients. As withprior studies that found similar reductions in resourceuse (4 –7), these substantial savings were achieved with-out diminishing quality or patient satisfaction. Nor wasthere evidence of cost shifting: hospitalists’ patients wereno less likely to be discharged to home (instead of anotherinstitution such as a skilled nursing facility) than werepatients of primary care internists. We can now state withconsiderable confidence that hospitalists markedly de-crease inpatient costs and lengths of stay with no compro-mise in quality or patient satisfaction.
    1. Five years ago, it was accountable care organizations and value-based purchasing that SHM glommed on to as programs to be embraced as heralding the future. Now it’s the Bundled Payments for Care Improvement initiative (BCPI), introduced by the Center for Medicare & Medicaid Innovation (CMMI) at the Centers for Medicare & Medicaid Services (CMS) back in 2011 and now compiling its first data sets for the next frontier of payments for episodic care. BCPI was mandated by the Patient Protection and Affordable Care Act (ACA) of 2009, which included a provision that the government establish a five-year pilot program by 2013 that bundled payments for inpatient care, according to the American Hospital Association. BCPI now has more than 650 participating organizations, not including thousands of physicians who then partner with those groups, over four models. The initiative covers 48 defined episodes of care, both medical and surgical, that could begin three days prior to admission and stretch 30, 60, or 90 days post-discharge. <img class="file media-element file-medstat-image-flush-right" height="220" width="220" alt="Dr. Weiner" typeof="foaf:Image" src="https://www.the-hospitalist.org/sites/default/files/styles/medium/public/images/weinerweb.jpg" title="" />Dr. Weiner “The reason this is so special is that it is one of the few CMS programs that allows providers to be in the driver’s seat,” says Kerry Weiner, MD, chief medical officer of acute and post-acute services at TeamHealth-‎IPC. “They have the opportunity to be accountable and to actually be the designers of reengineering care. The other programs that you just mentioned, like value-based purchasing, largely originate from health systems or the federal government and dictate the principles and the metrics that as a provider you’re going to be evaluated upon. “The bundled model [BCPI] gives us the flexibility, scale, and brackets of risk that we want to accept and thereby gives us a lot more control over what physicians and physician groups can manage successfully.”

Low-level interop has a high floor, high ceiling. Higher-level interop (like Smalltalk) has lower floors, because deeper system integration. However, that deeper integration often means you end up more entangled with the system’s strengths and weaknesses.
    1. It has been demonstrated that this formulation is almost equivalent to a SLIM model,[9] which is an item-item model based recommender

      So a pre-trained item model can be used to make such recommendations.

    2. The user's latent factors represent the preference of that user for the corresponding item's latent factors

      The higher the value of the dot product between the two, the higher the preference.

    3. two lower dimensional matrices

      Not necessary (in fact, often not) square. Typically each user is represented by a vector of dimension strictly less than the number of items and vice versa.

    1. Across the technology industry, rank-and-file employees are demanding greater insight into how their companies are deploying the technology that they built. At Google, Amazon, Microsoft and Salesforce, as well as at tech start-ups, engineers and technologists are increasingly asking whether the products they are working on are being used for surveillance in places like China or for military projects in the United States or elsewhere.

    1. An obvious metaphysical question to raise here is the compatibility or otherwise of religion and transhumanism. In my 1990 essay that first set forth modern transhumanism as a distinct philosophy under that name, I explained how transhumanism (like humanism) can act as a philosophy of life that fulfills some of the same functions as a religion without any appeal to a higher power, a supernatural entity, to faith, and without the other core features of religions (More 1990). The central place accorded to rationalism suggests a tension between transhumanism and religion. But are they actually incompatible? Since rationalism is an approach to acquiring knowledge and says nothing about the content of knowledge, it is possible in principle for a transhumanist to hold some religious beliefs. And some do. The content of some religious beliefs is easier to reconcile with transhumanism than the content of others. Christian transhumanists, while not completely unknown, are very rare (and I know of none who are fundamentalists, and such a combination would surely indicate deep confusion). There are more Mormon transhumanists (although some of these are cultural rather than religious Mormons), perhaps because that religion allows for humans to ascend to a higher, more godlike level, rather than sharply dividing God from man. Several transhumanists describe themselves as Buddhists (presumably of the secular, philosophical type), and there seem to be few obstacles to combining transhumanism with liberal Judaism. However, the vast majority of transhumanists do not identify with any religion. A pilot study published in 2005 found that religious attitudes were negatively correlated with acceptance of transhumanist ideas. Those with strong religious views tended to regard transhumanism as competing with their beliefs (Bainbridge 2005).

      Having a strong belief system is naturally integral for humans. Religion is by far the most common, profound form of human belief systems, so it is relevant to propose the question of transhumanism and religion being incompatible. While it is possible that the basis of each religion can contribute to an individual's probability of simultaneously believing in transhumanism, having a belief system that consists of both beliefs would presumably be rather conflicting for any individual to concurrently believe in.

    1. an environment unlike anything they will encounter outside of school

      Hm? Aren’t they likely to encounter Content Management Systems, Enterprise Resource Planning, Customer Relationship Management, Intranets, etc.? Granted, these aren’t precisely the same think as LMS. But there’s quite a bit of continuity between Drupal, Oracle, Moodle, Sharepoint, and Salesforce.

    1. What is this again? What Google Drive should be. What Dropbox should be. What file systems can be. The way we unify our data access across companies, services, programs, and people. The way I want to live and work.

      I think that this is interesting, but idealistic. The code repo on GitHub is quite active, but how does a technology like this gain traction?

    1. The absence of a need for co-signaling through CD28 for these BiTEs might also be explained by the observation that among all T cell subtypes, CD8+ effector memory cells CD45RO+ (TEM) and CD8+ effector memory CD45RA+ (TEMRA) contribute the most to BiTE activity, whereas naïve T cells do not contribute at all to the killing efficiency.50 It is believed that memory T cells do not require CD28 costimulation for expansion during secondary responses, which could explain the efficiency of BiTEs. However, this dogma has recently been challenged.5

      absence of need for cosignal effector memory cells contribute most to bite activity memory T ells dont require cd28 costimulation for expansion?

    1. NixOS is a Linux distribution with a unique approach to package and configuration management.

      This is another approach to systems management and software as a services. I don't really understand in detail the difference between NixOS and docker, but googling NixOS vs Docker shows that its a topic that is ripe for a bunfight.

    1. Multi-party Conversational Systems are systems with natural language interactionbetween one or more people or systems. From the moment that an utterance is sent toa group, to the moment that it is replied in the group by a member, several activitiesmust be done by the system: utterance understanding, information search, reasoning,among others. In this paper we present the challenges of designing and building multi-party conversational systems, the state of the art, our proposed hybrid architectureusing both norms and machine learning and some insights after implementing andevaluating one on the finance domain.

    1. This is why people can play the piano with their fingers but not with their toes.

      That does not really explain why there are very talented musicians that have limb defects, but I suppose that similar to a blind person being able to hear better, their brains adjust (like complex-adaptive systems do) and reassign a new input-element (e.g. the feet) to a left-over motoric system(e.g. the hands).

    1. There may well be a dominant reading, but this can erode over time if the “interpretive community” (Fish 1980) to which it speaks changes or the message lost entirely if that com-munity is decisively disrupted or displaced.14

    1. And now we’re besties again.

      I can relate. I have deep respect for AK but often find myself flipping back and forth between strong agreement and feeling somewhat off-put by what he writes. That seems like a healthier relationship to have with any public intellectual though than 100% agreement 100% of the time. I'm so glad his writing exists in the world and I'm glad yours does too. Seems like this kind of layered relationship is just part of dealing with complex systems. :-)

    1. Today, we’re announcing the end of Chrome’s support for Windows XP, as well as Windows Vista, and Mac OS X 10.6, 10.7, and 10.8, since these platforms are no longer actively supported by Microsoft and Apple. Starting April 2016, Chrome will continue to function on these platforms but will no longer receive updates and security fixes.

      Google announcement from 10 Nov 2015.

      Estimate of operating system usage.

      Microsoft security updates for Windows Vista are scheduled to continue until 11 April, 2017.

    1. Stupid models are extremely useful. They are usefulbecause humans are boundedly rational and because language is imprecise. It is often only by formalizing a complex system that we can make progress in understanding it. Formal models should be a necessary component of the behavioral scientist’s toolkit. Models are stupid, and we need more of them.

      Formal models are explicit in the assumptions they make about how the parts of a system work and interact, and moreover are explicit in the aspects of reality they omit.

      -- Paul Smaldino

    2. Microeconomic models based on rational choice theory are useful for developing intuition, and may even approximate reality in a fewspecial cases, but the history of behavioral economics shows that standard economic theory has also provided a smorgasbord of null hypotheses to be struck down by empirical observation.
    3. Where differences between conditions are indicated, avoid the mistake of running statistical analyses as if you were sampling from a larger population.

      You already have a generating model for your data – it’s your model. Statistical analyses on model data often involve modeling your model with a stupider model. Don’t do this. Instead, run enough simulations to obtain limiting distributions.

    4. A model’s strength stemsfromits precision.

      I have come across too many modeling papers in which the model – that is, the parts, all their components, the relationships between them, and mechanisms for change – is not clearly expressed. This is most common with computational models (such as agent-based models), which can be quite complicated, but also exists in cases of purely mathematical models.

    5. However, I want to be careful not to elevate modelers above those scientists who employ other methods.

      This is important for at least two reasons, the first and foremost of which is that science absolutely requires empirical data. Those data are often painstaking to collect, requiring clever, meticulous, and occasionally tedious labor. There is a certain kind of laziness inherent in the professional modeler, who builds entire worlds from his or her desk using only pen, paper, and computer. Relatedly, many scientists are truly fantastic communicators, and present extremely clear theories that advance scientific understanding without a formal model in sight. Charles Darwin, to give an extreme example, laid almost all the foundations of modern evolutionary biology without writing down a single equation.

    6. Ultimately,the theory has been shown to be incorrect, and has been epistemically replaced by the theory of General Relativity. Nevertheless, the theory is able to make exceptionally good approximations of gravitational forces –so good that NASA’s moon missions have relied upon them.

      General Relativity may also turn out to be a "dumb model". https://twitter.com/worrydream/status/672957979545571329
