They’re at it again. Yes they are… As part of the Rube Goldberg contingent from Mythinformation Central. From the people that brought you “you’re fat because of your friends” you are now presented with: “your genes influence who will become friends.”

They set up the straw man: that it is an error to suggest people are a function of a “simple model for the metabolic, neural and Internet networks, and the same model is applied to human beings — that all parts of the network are identical and interchangeable”.

They never knock it down but extrapolate beyond the data with innuendo of their own PR. One can only imagine that Christakis and cronies will be doing collaborative work with Steven Pinker soon on the topology of the mind, call it science and write another book on the mind’s influences in support of Pinker’s postulate that the reason the Chief justice misquoted the oath of President Obama was a “blowback from Chief Justice Roberts’s habit of grammatical niggling Or was it a Freudian slip? Hmmm… Science, huh... How very canny for the Language Don Dr. Pinker to point that out as he knows so much about both people’s histories, relevant factors and ‘mindful’ homunculi like those “inherent characteristics that govern where we [as individuals] gravitate to in the social network.”

“A second implication is that the [current] study suggests that if we really want to understand how things [?what ‘things’?] diffuse in social networks, we need to take into account people’s locations in the social networks, which are due in part to their genes,” Christakis pontificated while showing no data or peer reviewed research.

Please see the Baloney Detection Kit submitted for consideration for those reading content from any media channel, including Buzz Creation or Mythinformation efforts by mainstream print media to get more subscribers and kooks to buy their fading printed words.

I am looking forward to more “sharper predictions” from the Christakis Mythinformation crew.

IEEE’s Spectrum magazine has an excellent article about memristors and their history. This is an excellent overview piece written for a wider audience.  It clearly explains how the memristor came to be, why it matters, and what exactly it is.

It’s worth noting that Memristors have relation to cellular automata and neural networks, at least in originators.  Leon Chua is one of the main researchers behind Cellular Neural Networks and predicted the existence of memristors.  Also of note is the typical path of MIT, U of Illinois Champaign and Berkley – shared by many others working in similar disciplines.

Methinks the relationship between memristors and other cellular automata like theoretical models is much deeper than just the research instituations.  Wolfram mentioned the possibility of a parallel computing architecture based on CAs, perhaps the memristors plays some role in all of this.

Anyhoo, read the article.  Memristors will be significant in computing design.

‘Thinking’ as a class of potential behavior is hard to study and thus, makes it ripe for speculation and interpretations beyond the data. As things are today, thinking is made more significant because it is presumed that humans are the only ones that do it making is a signature feature on what is human and what isn’t. “Mind”, “consciousness”, thought and all sorts of covert related properties are offered as evidence that humans are different and somehow more substantive than other animals. The past and existing organizations of what is going on inside the ‘vault’ [read: brain, head, mind, neural node, CNS] have been dismal. Answers are as elusive as they were 2000 years ago and are made more mysterious for some by being out of reach.

We have made no progress in regards to our understanding of what goes on there and how those things relate to subjective or empirical states of man or our institutions, including governance and law. They have suffered most while we hack away at deciphering the muddled mess of metaphysics and logically indefensible postulates that are put forth to explain how man behaves and why.

the verbal community has not yet been able to connect with what is going on that the community cannot experience. Any reinforcements that are delivered are not contingent on specific behavior because they can’t be seen in time or space. This comes to create a response class that looks like behavior that is reinforced on a VI schedule independent of a specific response on the part of the target organism. Yes; the prime requisite for development of superstitious behavior is non-contingent VI delivery of a reinforcer.

thinking may occasion in a person a fixed gaze, unblinking or reduced eye blinks, change in gate, or time insensitivity to many external stimuli, changes in galvanic responses and lowered heart and breathing rates. However, these are not thinking per se but may be part of what is inferred to be happening when one is doing any covert behaviors including thinking. All are part of other behaviors as well as behaviors with parameters of their own.

In describing thinking there is a lack of external conformation possible that any observer or the free-floating reinforcements can access. Thus, there is no connection between a specific covert behavior and a potential reinforcer. Thus, there is no way to show an increase in the future probability of occurrence of a target covert behavior occurring when the potential reinforcer was delivered.

Our covert behavior [including thinking] has several problems as a behavior class.

  1. it is not sensed and can’t be verified or falsified
  2. it does not have standard units of measurement
  3. results will depend on the way it is measured
  4. it is experiences through filters that transducer it to something else based on history and context
    1. vocabulary
    2. environment context
    3. culture
    4. in articulation of aspect (what parts are of interest – dreams, impulses, value, etc.)
    5. unknown empirical properties

Ultimately, the products of processes generated from within the ‘vault’ of the listener are routed and locked there. Everyone will continue to investigate how and what is going on there with whatever methods that can be mustered. Today the neurosciences are taking their shot at deciphering the relationships between what is going on inside our head and what we experience. To that end they are using 19th century models of man and behavior mixed with decrepit autonomous man inklings and sophisticated 21st century technology and chemistry. For some there is value in how they postulate the working of man and his mind. Those values are the same as postulated 2000 years ago and haven’t benefited our species as much as science methods have benefited biology, chemistry and anthropology. The value to science will depend more on changes in approach to man than the power of the magnet used in a portable fMRI.

Any set of the things related to what happens when someone is thinking is all just that, related to thinking for that person and not thinking itself. All the covert events can be related to things associated with other behaviors done when a person is not thinking as well as when some are thinking. The set of responses become associated as events related to a state that may be referred to as ‘thinking’ for that person who, when asked, “What are you doing?” or “Why don’t you answer me?” may report, “I was thinking…” and otherwise communicate something the other person will probably relate to as a set of private covert actions (events) that can be arbitrarily called ‘thinking.’

Of course it is very true that if thinking were an operant the people in the examples above would not have to ask, “What are you doing?” or “Why don’t you answer me?” If thinking were doing something overt, the observer could learn from observing or measuring behavior and would know the answers to those questions after learning to discriminate what was/is thinking and what is something other than thinking.

Psychotherapists, bosses, clergy, spouses, friends, parents etc., all have a version of why we do what we do. They have a story about what relationships exist between us and the world around us; the environment. There is a good chance that, after some time experiencing a person, that each could be right. Of course their story is riddled with inaccuracies as well seeing how they only see what they were trained to see. Seems impossible but consider that each of us has a VERY broad and complex behavior repertoire. Our complex behavior allows us to behave differently and distinctly in the different environments and contexts of different people. Sometimes the people we are, how we behave, overlaps. Sometimes they don’t.

SUMMARY

Great thinkers as well as the delusional philosophers, pontiffs, despots and princes and even the man and woman on the street have been reinforced for reporting their internal covert musings in subjective and fantasy terms focusing on the exhaust of the human thinking process – emotions and feelings. These 3 thousand years of focus has outdistanced the empirical study of thinking by overlooking histories of the individuals and the use of the least productive research methods NOT found in 17th century science! In the not-so-grand scale of things, it is more interesting for the lay person and the scientist alike to be enamored by the fantasy than by the environmental contingencies. We pay for that interest every day we live on this earth.
