Do you trust who I am?

Thursday, March 13th, 2008

Philip Zimmermann’s Pretty Good Privacy was a critical platform for educating the world on secure communication. PGP encryption is so good, that even the most determined agencies can essentially go pound sand–it is pretty good privacy to be humble, not to disclaim. An impressive concept with PGP is the public and distributed nature of key management. Often, Public Key Encryption systems rely upon Public Key Infrastructures where there is a central authority. The genius of Zimmermann is in the notion that keys have an associated trust level. That your personal key can be trusted by you, implicitly. Your friend’s key, depending on how you came into position may have a high level of trust associated with it, that this key is in fact his or hers. Furthermore, you can sign other people’s keys, an endorsement of the validity of that key. You see, public keys are what the system uses to encrypt secure messages that only the key holder knows how to decrypt using their private key. By introducing the notion of trust and the digital signing of keys, Zimmermann started what has to be seen as an early social web–a social graph of the people you could not only securely exchange email with but a social confidence of the key itself and by extension the individual’s digital identity.

In A Crowd of One: The future of individual identity, John Henry Clippinger starts working through how much society defines good and bad. Simply put, one person’s radical is another person’s hero. The examples are uncanny and for each of us there is one with which to resonate. If you make it past the prologue and the bulk of chapter one, you will be delighted by page just prior to chapter two, which lays out where you hoped the book would go. There are heavy-eye moments in chapter one where you think Clippinger is too smart for you and his messages are going to be far too academic to appreciate–page 24 turns it around.

Clippinger talks about how biological evolution is particularly challenging in that generations of “sexual selection and reproduction” need to pass to accomplish the natural order. Societal evolution on the other hand can happen quickly and most participants in the modern world can attest, things they are a changin’.

Furthermore, it will become possible to have governance by algorithm—that is, have computer-based rules assign reputation scores, rate the performance of members of a social network, identify and expel free riders, and maintain the requisite checks and balances between competing interests.

We’re largely digital, we just haven’t appreciated what it can tell us about ourselves.

Both quotes from A Crowd of One, Page 24

Participation is often a key aspect of reputation in online venues where almost everyone is anonymous. An active forum participant rises through the ranks having established a history and dedication among participants accruing digital karma. E-Bay and Amazon have similar reputation models where the number of successful interactions connotes some degree of comfort in interacting with strangers or new products. Other social spaces like FaceBook display social graphs, implicit endorsements. Almost all of these cases either require a human to judge the content or trust in very week measures of past interaction. Regardless, as participants we leave an endless trail of social data, something Google is more than happy to store forever and bring together. Our infatuation with the social graph and the affiliation with social spaces is rooted in the quest to see our own reflection. Other people help manifest our identity (or identities) and in reflecting on our connection, attitudes and culture we participate in societal evolution. We are largely digital and while we have not yet appreciated how much of our web teaches us, we are far more ignorant of what it could tell us that we cannot see or do not know.

Some cultures have teachings of how painfully alone we are as beings, that we are very much isolated, despite our unquenchable desire to connect with others. As children moving through years four to six, we develop self-consciousness at a very specific point in time – at one point it is another child in the mirror and then suddenly we know it is us. Humans are unaware of themselves and then once aware struggle to manage their identity. We construct much of our reality as a means for creating our identity and look to others to reflect and locate how far we have come. In a digital world where the social network is out in the open, how does a more sophisticated notion of trust, identity and security come about? Is it the culmination of all I do online? Who is I? Which email address? Which identity? How many social connections do I need before I am trusted? At what cost do we ascertain identity?

Zimmermann was on to something–decentralizing authority, driving validation into the network and ensuring confidentiality. Clippinger brings us full circle, showing us that our digital fingerprints and the systems that judge us will be equal actors in constructing who we are. If the rest of this book is as good, we are in for a treat!

Ambient connections create more socially aware networks

Saturday, September 29th, 2007

Twitter is a centerpiece to techi-discussions where everyone shakes in amazement that such a simple application could become so integral to people’s lives. It is the simplicity, content and medium that supports such phenomenal adoption. More specifically, the interfaces to Twitter are minimal – website, email, feeds, Twitter Tools (extensions to Twitter) and most importantly text messaging. The website supports initial account creation, management, historical archive and message broadcasting, but in truth, like every other website would require a user to show up to participate and benefit. Extending their interface to email offers the few people who have a computer but no mobile phone a way to engage, but it is the text messaging that lets Twitter reach down and touch you in your pocket. There is too much information and yet participating in Twitter only increases it. So, why are we experiencing such compulsion?

Twitter has been described as micro-blogging and it is not a terrible coin. Twitters are character limited training people to marshal life updates into pithy messages. If one made a valuation of a blog post that journals a person’s day-to-day activity, the value in any given twitter is at most proportionally as small. However, considered in the context of the same person’s daily twitters and an individual’s understanding is enhanced. Consider one person’s twitters in their twitter-network cocktail and the twitter-log takes on additional meaning, meaning only understood by the receiver. Throw into the mental mix that one person does not necessarily need to know another in order to follow them – supporting fantastical senses of potentially very distant individuals.

Blog-trolling a last weekend I remember running across Matt Hatem’s reflection on the social sixth sense. He actually ends up meeting a friend that he might not have otherwise through Twitter. Interestingly, Matt’s very real social connection enhances his relationship with Twitter. Regularly, Twitter is a simple way to keep up with his network virtually. He is left to construct what one buddy is up to based on what he knows of them and what the message said. In his example, though, Matt bridged the relationship into the real world, which is far richer and now forever part of how Matt understands Twitter – it connects him with people he knows – virtually and in the flesh.

Matt also points off to Clive Thompson’s Wired article How Twitter Creates a Social Sixth Sense. Clive offers similar anecdotal support that small messages understood cumulatively have meaning, meaning that changes what we understand about the people we know. The fact that these messages show up on a mobile phone – a intimate device – offers urgency of interruption and often a visually simple rolling log of what is what in the network. The mobile phone has become an ambient device that creates more socially aware people, in some cases, actually getting them away from tiny keyboards and meeting up close enough to touch.

Common canvas of distinguishing features

Thursday, September 13th, 2007

Chris Chase, a neuropsychology professor back in college, enjoyed introducing concepts with the notion that humans are more alike than they are different. It is a useful foundation for deciding what is important to study, fundamentals that apply to everyone or the anomalies, certainly not unimportant, just narrow. And yet, humans are fascinated with differences and in particular our faces and our bodies.

Slavko Milekic, the chair of my undergraduate thesis on child friendly interfaces, evolved the face flipbook into kid-friendly touch-screen interfaces. Earlier on, in a self-study project I implemented the more traditional version of a face flipbook, allowing someone to switch parts of faces but in a more literal representation to the kid books I grew up with.

Reminder: There are too many examples of literal expression in virtual spaces that fail. It amazes me that we tend to not take on the larger challenges of inventing something new instead of replicating what we know.

Slavko introduced gesture and touch based interactions to the traditional computing environment enabling object switching, size shape and position. Certainly one of his successful creations was that of assembly of faces out of a variety of common objects like vegetables. Even at a young age, even when working with vegetables - something often seen as a challenge for children - we are fascinated with the construction of human form.

Move to the more taboo example of human nudity in art or even pornography. There are books dedicated to human genitals – again, the differences. Even when considering the world of fantasy and identity, nudity and pornography depict other people doing things that you yourself could do, by yourself, with others you know and increasingly others you do not know. So why that fascination, if not for the differences. What is it like to see an attractive someone with a certain set of features? It is all about the distinguishing marks, regardless of it being labeled art or smut.

My recent move back to New York City, more specifically Brooklyn, reminded me of the diversity I missed. A great Walt Whitman quote on a Barnes & Noble ad in my subway car read,

Stranger, if you passing meet me and desire to speak to me, why should you not speak to me? And why should I not speak to you?

That must be what outgoing is, talking to the diversity around you instead of just observing. But, in fact, almost no one speaks to strangers – we even teach our children not to. However, everyone has the pleasure of enjoying diversity visually at fire hose volume in New York City and for me on my morning commute on the F train.

Professor Chase is still right, we are more alike than we are different and while we are consumed by those curious differences, I posit that our fascination exists because our distinguishing marks appear on a relatively common canvas.

Compulsive addiction to language

Saturday, December 23rd, 2006

WNYC runs a series called Radio Lab, a curious investigative exploration of the world that distinguishes itself with an immersive layering of sound and narration. I recently listened to the Radio Lab podcast, specifically show number 202, Musical Language, originally aired on April 21, 2006. Jad Abumrad and Robert Krulwich host a trip looking at how the brain processes sound, and a fascinating trip it is.

Our hosts focus on how we perceive music and how language is actually very close to song. Most of us are verbally expressive and we are expert in changing the execution of our speech to communicate overtones and undertones. They interview a series of academics to explore what we understand about sound and how it is understood.

Diana Deutsch, is a professor in University of San Diago’s psychology department studying tone languages, where the same word has different meanings depending on the tone they are spoken in. Anne Fernald, Stanford Associate Professor of Development Psychology, has looked at how specific tones communicate to young infants – universal across languages. “Sound is more like touch at a distance.” Tone is a fundamental component in communication and it begs the question - What happens if you are tone deaf? Does a person of perfect pitch understand language differently?

Jonah Lehrer, author and Rhodes Scholar with a degree in neuroscience, helps us understand how sound transmits from speaker to ear. The voice box compresses air, sends waves to the eardrum, vibrating the bones, rippling fluid in the ear, releasing electricity and then our brain interprets that as sound. Mark Jude Tramo, Harvard Assistant Professor of Neurology, actually listens to the electricity and even at this low level, pleasant sounds have consistent meter, while unpleasant sounds have inconsistent meter. The word pleasant is obviously subjective, but establishes a point for discussion, after all people seem to be able to appreciate even the unpleasant – the pleasant can often become pleasant with repetition, time and linking to other highly valued experiences.

What happens when you cannot hear? Obviously, these electrical pulses are not stored along with other information in the brain. Yet it is common to read how people with disabilities develop higher sensitivity with their other senses. Considering that these tuned senses reflect the human potential, can everyone develop heightened senses, or do we need to lose one to gain development in another? Do people who do not have the use of one sense store additional information – understand and experience at a richer level, or is it just different – can it be richer if it is missing a key sense such as smell?

What is it that we find pleasant and why is it that we can so easily shift the unpleasant to the pleasant? Lehrer describes how our brains are always trying to assimilate foreign changes in audio input. Can we extrapolate that to other senses? People have different pain thresholds, derive a certain level of enjoyment from it – an outdoor hot tub in the winter can be particularly biting, but relaxing all the same. Different types of alcohol require an acquired taste – whisky is not exactly hot chocolate. Almost all alcohol varieties cultivate experts that can discern even the most subtle elements from seeing, smelling and tasting. One person’s Syrah is another person’s Sancerre, yet to a new wine drinker both might offend.

Another question: What is it when we develop addictions and what are we addicted to – the signals to the brain or the experiences we engage in? What does it mean to abuse an experience? Society tends to see harmful behavior, such as smoking and excessive drinking as addictive and abusive. If my addiction is to coffee, reading or love then it is generally accepted, even though I might actually be damaging something unknown or unseen. I am not convinced that there is anything substantially different from one compulsive behavior to another – our brains (and our bodies through our brains) create custom drug cocktails of pleasure and the vices we have affinity for might very well be arbitrary.

Medicating the future

Saturday, November 25th, 2006

I am a believer that we are both the creator and observer of our own reality. What does it mean then if you have an overpowering psychological condition like severe depression, schizophrenia, bipolar or obsessive compulsive disorder? The belief can still stand, but it is fair to say that the chemistry and construction of the brain and body got a little too creative, or maybe not creative enough.

I have experienced through reading, administering developmental and behavioral experiments in college and, best of all, life, a variety of people with their demons. In every case, even when they were labeled with the same words, the demons were different and more importantly, the people were different. I start listening as if I know nothing, because for any given person it might be different and who am I to put my baggage on them.

For all the desire to master the brain through therapy and psychopharmacology, everyone is a unique case that we flounder to understand, the most talented among us saving our fellow man. Add to that my general feeling that we all have demons, even the most blessed and hopefully you get a sense that I am not against medication. I am, however, against what is a growing trend of medicating without answering why we are suddenly in the position of having to do so at such an alarming rate. A recent New York Times article, Proof Is Scant on Psychiatric Drug Mix for Young, by Gardiner Harris, pulled together some great research on medicating children.

Antidepressants are commonly paired with stimulants, but antidepressant use has declined over the last year after the F.D.A. warning about suicide risk. In their place, physicians are prescribing combinations that include antipsychotic and anticonvulsant drugs, according to Medco. From 2001 to 2005, the use of antipsychotic drugs in children and teenagers grew 73 percent, Medco found. Among girls, antipsychotic use more than doubled.

As with almost anything worth thinking about, there is plenty of complexity below the surface. This article is about how we medicate our children, apparently 1.6 million of them with 280K under 10 years old. To be counted, they needed to be prescribed two psychiatric drugs.

More than 500,000 were prescribed at least three psychiatric drugs. More than 160,000 got at least four medications together, the analysis found.

Harris tells us that some studies show adults benefiting from two drug cocktails specifically around depression, OCD, and the mania associated with bipolar. As with any study, others show no conclusions of import.

The use of two-medicine combinations in children is on much shakier ground. Even for single drugs, the effectiveness of some psychiatric medications in younger patients is questionable: most trials of antidepressants in depressed children, for instance, fail to show any beneficial effect. But hardly any studies have examined the safety or the effectiveness of medicine combinations in children. A 2003 review in The American Journal of Psychiatry found only six controlled trials of two-drug combinations. Four of the six failed to show any benefit; in a fifth, the improvement was offset by greater side effects.

If the evidence for two-drug combinations is minimal, for three-drug combinations it is nonexistent, several top experts said.

As members of one of the most developed societies, it is safe to say even the adults are struggling to make sense of their world, even the non-medicated. We have data showing that since 2001 we have begun heavily medicating our children in ways our best psychiatrists are unable to rationalize. If the reality we create in our minds, arguably the only reality that exists, is unnecessarily affected by doping, what is the affect on our ability to construct a different one?

For some, medication brings them closer to center, often with side affects, but more desirable than being consumed with self-destruction. I have heard that relative to their un-medicated state, some drugs slow things down too much or keep people in a fuzz. I think it is probably worth it if you suddenly have the opportunity to ponder the world of your design - for all you know you might be living in someone else’s.

For those of us who are challenged with loved ones who need medication, may we have the wisdom to withhold our own discomfort and psychological effects, so that medicating is done, not for us, but for you. As for the overly medicated children among us, may we not screw you up to the point where you can no longer consider what is real.

Feeling conscious

Friday, October 27th, 2006

Neuropsychology could have easily been my first profession. My fascination for the brain and appreciation for how little and much we know of it has always captivated my logical and imaginative thought.

I just finished the book, Wider Than The Sky: The Phenomenal Gift of Consciousness, where Gerald Edelman, M.D., Ph. D. covers an impressive amount of information refuting that consciousness is solely metaphysical. While anyone can argue there is mystery to the brain, Edelman’s work is persuasive – there are neurological constructs which give rise to consciousness.

Quale (IPA [ ˈkwɑːle]) is the way something feels, an experienced conscious moment. The definition’s subtly fails to describe the complex recipe that comprises a feeling –

sensory input, consequences of motor activity, imagery, emotions, fleeting memories, bodily sensations and a peripheral fringe. (p. 61)

Our experience, being conscious of being conscious naturally contains all of these things all of the time. It would be trivializing to say it is like a movie where only audio and visual aspects are perceived. Qualia consider the past, the current and the possible future, all at the same moment, all the time, becoming part of the categorized catalog of discriminated conscious states influencing future qualia.

In order to fully understand the data set that is flowing throughout the brain, we would actually need to be that body, that brain. The information outside of that context can only be imagined. An example used was, “what would it be like to be a bat?” illustrating the complexity – it would actually be easier to understand what it would be like to be another human, but is quite literally, impossible.

Recently on CBS Sunday Morning, Mo Rocca questioned if as we live longer and medical technology continues to deliver higher quality transplant and artificial replacement, will you still be you? Assuming that the replacement of an organ is successful, the brain would read the new organ as part of new quale. What happens to the qualia associated with the failed organ? Does the brain simply treat those discriminations as part of a phantom part of a quale – similar to the sensation some people experience when losing a limb, or, is some of the data lost forever? Does the new organ have the ability to read the data stream as part of the body and brain? Does the replacement organ, know something that the failing organ did not?

So, Mo, I think the answer is yes, probably, you will still be you, but a different you.

Have a hug, trust me

Monday, September 11th, 2006

I heard today that hugs over twenty seconds create more trust. A little research shows that oxytocin [ok-si-toh-suhn] is at the heart of this thinking – a neurotransmitter in the brain expressed in women during labor, breastfeeding and when males or females orgasm.

Zack Lynch, someone who seems to be well regarded, highlights the research of Paul Zak and Ahlam Fakhar which shows that increases in oxytocin and estrogen affects country wide levels of trust. Lynch summarizes the findings ending with “trusting people are happier.” Dr. John Schinnerer, added that Shelly Taylor’s research links oxytocin as the foundation for the difference in innate reaction to fear when comparing males and females. Taylor et al. conclude:

It is now well-established that both animals and humans show health benefits from social contact (e.g., House, Umberson, & Landis, 1988). Positive physical contact in the form of touching, hugging, cuddling, and the like is known to release oxytocin which, in turn, has anti-stress properties. The present analysis suggests some mechanisms whereby social support may provide health protection … accompanying relaxation. As such, oxytocin may confer health benefits (cf. Ryff & Singer, 1998).

Dr. Schinnerer gives us the winning quote:

…oxytocin can be produced via hugs longer than 20 seconds which creates more trust in women.

Simple lesson of the day, hug more and hug longer.

The rise of a truly literate class

Tuesday, August 29th, 2006

I once heard that eighty percent of what we think of today, we thought of yesterday. I enjoy optimizing my world, so increasing the percentage of new thought seems a worthy goal.

Wikipedia lists the United States having a 99.9% literacy rate, citing the CIA World Fact Book. Check the footnote reading that 44 million people (one in seven) can read but not to level of understanding a job application, a food label or utility bill. Consider the fact that when I consider literacy, I do not include this group of 44 million.

Among the educated workforce – college level and above – I routinely witness great disparities in literacy. Being able to read and write are the single most important capabilities of an educated mind and those who write well often read.

Reading is an activity where the brain is engaged. Active readers comprehend the content, exploring what it means. The content influences the formation of language and founds our ability to create more complex conceptual relationships. This complexity adds layers of depth to our thinking and appreciation of the world around us.

Add to the list of what it means to be literate the appreciation of art and music and we get closer to what real literacy is about. There is a texture that only can be felt by wide exposure to new ideas through the mediums of text, images and sound. More importantly is for us to share the pieces of our overwhelming vast and growing collection of media that we believe are of meaningful quality.

The more we read the more we change and the less yesterday’s thinking is today’s.

Relationships with partners, mentors, muses and figments

Sunday, August 27th, 2006

Being better together is part of healthy relationships. Without one of the two something possible is suddenly not. Life in general has always struck me as an endless list of Choose Your Own Adventure. Pick something, live it and pick another. Anything is possible and some of the best choices are who we pick to connect with, to relate to.

We automatically get our parents, regardless of their availability and quality. No matter their condition, parents form foundational psychological artifacts creating a relationship. The impossibility was your existence and any psychological reality they provided you with, at a minimum their absence or presence.

An obvious relationship is that of the significant other, the wife, husband, girl-friend, boy-friend or lover. These are the people with whom you are truly better with than without and the one that society will identify as your other half. Together quality of life is often enhanced and more psychological artifacts are created, offering future possibilities to work through our reality and conceptions therein. We hope this person will deliver the trust, security and love it requires to break down deeper fears and barriers to wonderment.

Other fantastic relationships are those who are our mentors. Mentors are objects in the mirror that are closer than they appear. They are often individuals who can see something about you that you desire for yourself or they know you need and can help you achieve. In business, mentors are invaluable. They should be sought after even more in life. Even the bad ones teach some of the best lessons. The best transform in a way that no one else could – the envy of a significant other, the one who desires to be all things to their partner. While a significant other might be a mentor, they tend not to have the objectivity or know-how to articulate the required personal change. Mentors are often reverse mentored receiving from the relationship, not just giving. Together, both individuals have the opportunity to grow, create some more psychological artifacts, hopefully more building blocks than plaque.

Muses are a bit tricky. A muse inspires. Together the fruits of that inspiration better the world, regardless of the significance. The psychological artifacts come from both the interactions with the muse and the resulting product of the inspiration. For some a muse helps create better poetry and art. In other instances it is a significant other inspiring to create a better life, be a better person. Mentors could be muses, both helping move in a specific direction and acting as the model and inspiration for how to execute (i.e. how to act a certain way by replicating seen behavior). They can be people we do not know well or those who are our closest friends. Muses are important to have so that we may dream the next turn in our adventure instead of just turning the page to find out what happens.

Figments are things of our own creation. We are the lone creators of the psychological artifact. They help articulate the relationship we have with ourselves. Figments can be dreams or visualizations of our how we want the world to be.

One of the best questions I recently started asking of any relationship, is why am I looking for something here instead of somewhere else. It forces you to articulate the purpose of your actions and identify meaning specific to this relationship and in turn, the connections you have with others. With the multitude of relationships we create in the world, knowing why we seek the company of one and not another can deepen our understanding and connection to all.

What happens if you cannot feel the healing?

Saturday, August 19th, 2006

This past Friday afternoon, I was having an interesting conversation with a friend from work. We were talking about spas and more particularly massages – the general need and healing from being touched by other humans.

This morning on CNN a story ran on a child who never felt pain. I made a comment that it reminded me of the stories one might find by Oliver Sacks in The Man Who Mistook His Wife for a Hat, and more specifically the one about the woman who could not feel her own body.

CIPA (congenital insensitivity to pain with anhidrosis) is an inherited degenerative disorder affecting the autonomic nervous system – a big deal, as this is where the heart comes in and the nervous system lives. Two key symptoms surface as the lack of feeling pain and the lack of perspiration. In CNN’s story about Roberto, they mention he can not be held, because he sucks the heat out of you. My comment was not speaking to the scientific characteristics; instead it was one of the social impacts of not feeling.

What kind of mental model for pain would a person who can not feel it, have? What kind of mental model for world pain (not individual human suffering) would they have? If they do not have the concrete knowledge of pain, how would they work with the abstract concept when applied to thoughts, imagination, inanimate objects or abstract concepts like a country?

Reach back into a psychology class and thinking about Skinner and conditioning. Try and recall the experiment where the animal, I think it was a rodent, was provided food when it hit a lever – reward the rat and the rat will continue. Map this back to people with CIPA. In the absence of sensory stimuli and limited interactions with others (not being able to be held, presumably cuddled), what is created to match the Skinner-stimuli we all use to operate in the world? Roberto might be aware of a lava stone massage one might get at a spa, but not think much of it. For those who see touch as healing and the need for it, what does it mean for those with CIPA?
