She was Right the First Time, Too.

Judge Sotomayor’s retreat from her “rhetorical flourish” that a wise old Latina might decide better than a wise old man was the right tactic to secure confirmation, but it was also a retreat from our newly-gained understanding of how the human mind works. Back in 1890, William James formulated a general law of perception: “Whilst part of what we perceive comes through our senses from the object before us, another part (and it may be the larger part) always comes out of our mind” We now know that James did not go far enough. Even what comes to us through our senses is not what is actually out there, but a highly filtered construct created by brain circuits unique to each individual.

Our eyes don’t work like a camera. They wander in fits and starts about a scene while the retina cuts the welter of information into pieces: edges, changes, motion, contrasts, colors, textures, light and dark, eye status, and other image primitives that we don’t yet understand. The optic nerves transmit these to the back of the head where the brain starts to reassemble them into: line segments, segment pairings, orientations; then on up to outlines; to shapes; then objects; then concepts like “limb, leaf, dog, face, stone” and on to even broader constructs like “lithesome, laugh, dread, father, story.”

The response to any scene is unique to each individual. Circuits, built up by experience in one person, might deliver the perception: “old woman.” Another circuit in another brain would see: “wise Latina.” All the filtering and sorting in a third brain might trigger the elusive “grandmother cell” which stops the processing with the message, “that’s nana.”

As these higher-level perceptions are delivered to our conscious minds, most of the information that went into triggering those disparate interpretations is thrown away. Minds don’t clutter themselves with how the line segments were pieced together into a human outline, they just remember the final filtered output. This, by the way, should get us insensitive males off the hook for not noticing the color of that dress. It’s not that I couldn’t care, it’s that my life experiences never taught my mind’s filters to save or pass that information on to my front-end processor. Like words cut from early drafts of this essay, that data is simply not there to be noted or remembered, at least until my wife generates an important new life experience that creates in my brain a special circuit to insure that I do see and recall dress colors. Significant, repeated experience builds physical application-specific integrated circuits in our heads. In animals, we can actually watch those circuits develop. These filters are unique to each of us, created to let us see better, with no conscious thought, what we have seen before. No matter how much we might strive to be impartial observers, we simply cannot see what others see. They had different experiences and thus have different brain circuits.

My wife looks at a roadside and instantly sees half-a-dozen invasive exotic plants. My brain registers only green. A former boss looks at equations, things he works with every day, and instantly sees meaning. I struggle with the import of each symbol. It’s not just that he is three times smarter than I (although he is) but his experience has shaped specialty processors in his head to interpret what life has asked of his mind. Dennis Proffitt of the University of Virginia showed that everyone vastly over-estimate slopes (it comes as a great surprise to those of us who have driven up Lombard Street to learn that no road grade in San Francisco is greater than 18°). When tired, we see a slope as five to ten degrees steeper than we would had we been rested. This altered view of reality also varies with the observer’s longer-term life experiences, e.g., growing up on the planes or in the Colorado mountains. Iowans actually see slopes as steeper. These differences among people run amazingly deep. Richard Nisbett showed that they extend down to the very first steps we take to interpret the world; there are measurable cultural differences even in how our eyes scan a scene and on what features they dwell.

Brains are unique. People are unique. It is right for Judge Sotomayor to strive for objectivity. Even to aspire to impartiality is a triumph of human cognition. Still, as she, herself, pointed out in the hearings, we must seek to know what is true, not what we would wish to be true. What we do know should drive us to fill the Supreme Court with as wide a range of wisely-directed human filters as possible: Justices who will see truth in diverse ways. A wise Latina will make a healthy contribution to that mix.

Innovation is what happens when people do these two things together.

Saturday 1st August, 2009.

Lunched with Mom and daughter today. We have Ladies Lunches, when all three generations of us females go out to lunch together and share sandwiches, cake and giggles. We met Mom at the mall and she looked rather harassed.

She sighed, “I have this letter from the Council about my refuse collection and I don’t understand it so I brought it along for you to look at. I tried phoning but I just get one of those ‘push the button’ things and you know with my hearing….so I hung up.”

“No problem”, I said brightly. “Let’s get lunch in the Community CafĂ©, the food’s organic and they have the Community Computers free to use.”

I logged in using my Community Collaboration Online ID and password. I am registered for this town so I go straight through to our council’s virtual reception. I click on Refuse Collection and within a couple more clicks my avatar is in a room with the avatar of a Refuse Collection Advisor. We press the sound button and after some verification questions she talks to my Mom about the letter, and they have it all resolved in a few minutes. As my Mom is hard of hearing the Advisor text chatted as she spoke, so that my Mom could read it on the screen too. Mom was relieved to have the matter resolved, and very impressed.

Then Mom took my daughter off to check out the cakes on display, so I whizzed around some of the other Community Collaboration Online portals. I paid our council tax bill, booked a routine check for my husband at the health center, and confirmed that my avatar will be attending and filming next month’s PTA meeting at the virtual school (it’s my turn to do the video-minutes) – and all before our food arrived!

This doesn’t really happen in my town. Can it? Yes, and it can happen in your town too. I work part-time for a local government in England, and part-time for Rocoza Designs Ltd. At Rocoza we have two tags to keep us focused. The first is ‘virtual works for the real world’; if it doesn’t, there is no point in doing it. The second is ‘communicate - collaborate - innovate.’ Communication is not organisations talking to their customers, it is multi-directional, real-time, ongoing. Collaboration is not having a couple members of the public on the committee, it is the empowered sharing of ideals and ideas. Innovation is what happens when people do these two things together. I had the fascinating opportunity recently to co-edit the OGI Conference TweetBook (a first of its’ kind), despite being in England and the conference in DC event: One of my favourite quotes from this event is

#ogi Weinberger: The smartest person in the room is the room.

This inspires me, and a lot of people are doing great work with this philosophy already. My passion and imagination explode when that room gets to be virtual, because then it can include an unlimited number of participants, it can operate 24/7, be cross-departmental, cross-organisational, international, and like the OGI Tweetbook, innovative, participatory, and giving. This is what I imagine for my town. What can you imagine for your town – and beyond?

Marie Crandell, who lives in England, is Lead Designer and co-founder of Rocoza Designs Ltd, a not for profit company whose aim is to assist governments, educators and other NFP organisations to explore and utilise virtual worlds and web-based collaborative technology. She is also a Mom, and believes that our children need to excel in the two C’s: Computer skills and Community spirit.
