"The best thing for being sad," replied Merlin, beginning to puff and blow, "is to learn something. That's the only thing that never fails. You may grow old and trembling in your anatomies, you may lie awake at night listening to the disorder of your veins, you may miss your only love, you may see the world about you devastated by evil lunatics, or know your honour trampled in the sewers of baser minds. There is only one thing for it then — to learn. Learn why the world wags and what wags it. That is the only thing which the mind can never exhaust, never alienate, never be tortured by, never fear or distrust, and never dream of regretting. Learning is the only thing for you. Look what a lot of things there are to learn." — T.H. White, The Once and Future King

New Tools Help Information Overload

Take a sci­en­tific ques­tion like the genetic dif­fer­ence between humans and chim­panzees. Would you pre­fer to plough through an essay on the sub­ject, or to glance at the visu­al­iza­tion cre­ated by Ben Fry in which the 75,000 let­ters of cod­ing in the human genome form a pho­to­graphic image of a chimp’s head? Vir­tu­ally all of our genetic infor­ma­tion is iden­ti­cal, and Fry high­lights the dis­crep­an­cies by depict­ing nine of the let­ters as red dots. No con­test. Alice Raw­sthorn explains why.

EEGs Show Brain Differences Between Poor and Rich Kids

Kids from lower socioe­co­nomic lev­els show brain phys­i­ol­ogy pat­terns sim­i­lar to some­one who actu­ally had dam­age in the frontal lobe as an adult, said Robert Knight, a UC Berke­ley pro­fes­sor of psy­chol­ogy and direc­tor of their Neu­ro­science Insti­tute. This is a wake-up call. It’s not just that these kids are poor and more likely to have health prob­lems, but they might actu­ally not be get­ting full brain devel­op­ment from the stress­ful and rel­a­tively impov­er­ished envi­ron­ment asso­ci­ated with low socioe­co­nomic sta­tus: fewer books, less read­ing, fewer games, fewer vis­its to muse­ums. This study has been repeated many times in the last thirty years, with anal­o­gous results; this one is unique in that is sorts out the vari­ables that peo­ple have used to dis­count pre­vi­ous stud­ies and yet ends by ask­ing “Can this be repli­cated?” For heaven’s sake. What more proof do we need?

Google’s Gatekeepers

A sober­ing piece by law pro­fes­sor Jef­frey Rosen about the crit­i­cal and reluc­tant role that Google’s cor­po­rate gate­keep­ers play in decid­ing what we can and can­not see as it nav­i­gates the ter­ri­tory between pro­vid­ing neu­tral plat­form for free speech and a com­pany in the media and adver­tis­ing business:

“Right now, we’re trust­ing Google because it’s good, but of course, we run the risk that the day will come when Google goes bad,” [law pro­fes­sor Tim] Wu told me. In his view, that day might come when Google allowed its auto­mated Web crawlers, or search bots, to be used for law-enforcement and national-security pur­poses. “Under pres­sure to fight ter­ror­ism or to pacify repres­sive gov­ern­ments, Google could track every­thing we’ve searched for, every­thing we’re writ­ing on gmail, every­thing we’re writ­ing on Google docs, to fig­ure out who we are and what we do,” he said. “It would make the Inter­net a much scarier place for free expres­sion.” The ques­tion of free speech online isn’t just about what a com­pany like Google lets us read or see; it’s also about what it does with what we write, search and view.

Overload!

The tragedy of the news media in the infor­ma­tion age is that in their strug­gle to find a finan­cial foothold,” writes Bree Nor­den­son, “they have neglected to look hard enough at the larger impli­ca­tions of the new infor­ma­tion land­scape — and more gen­er­ally, of mod­ern life.” That is, infor­ma­tion over­load. Most of us lack the skills — not to men­tion the time, atten­tion, and moti­va­tion — to make sense of today’s unre­lent­ing tor­rent of infor­ma­tion. Far from pre­cip­i­tat­ing the demise of jour­nal­ists and news orga­ni­za­tions, it spells out why jour­nal­ism won’t dis­ap­pear. Paul Duguid explains: “[Infor­ma­tion] needs a rec­om­men­da­tion, a seal of approval, some­thing that says this is reli­able or true or what­ever. And so jour­nal­ists, but also the insti­tu­tions of jour­nal­ism as one aspect of this, become very important.”

Social Networks and Happiness

It seems to be the case, online as well as offline, that when you smile, the world smiles with you:

We found that social net­works have clus­ters of happy and unhappy peo­ple within them that reach out to three degrees of sep­a­ra­tion. A person’s hap­pi­ness is related to the hap­pi­ness of their friends, their friends’ friends, and their friends’ friends’ friends — that is, to peo­ple well beyond their social hori­zon. We found that happy peo­ple tend to be located in the cen­ter of their social net­works and to be located in large clus­ters of other happy peo­ple. And we found that each addi­tional happy friend increases a person’s prob­a­bil­ity of being happy by about 9%.

Obama In Your Heart

Ele­va­tion is one of a class of emo­tions that we feel when other peo­ple do good, skill­ful, or admirable things. These emo­tions are unusual in that they are not pri­mar­ily about our­selves, our goals, and our nor­mal petty con­cerns; rather, they make us feel like bet­ter peo­ple. Jonathan Haidt, who coined the term ele­va­tion, writes, “Pow­er­ful moments of ele­va­tion some­times seem to push a men­tal ‘reset but­ton,’ wip­ing out feel­ings of cyn­i­cism and replac­ing them with feel­ings of hope, love, and opti­mism, and a sense of moral inspi­ra­tion.” Barack Obama is appar­ently an off-the-charts ele­va­tion inducer. Haidt’s research shows that ele­va­tion is good at pro­vok­ing a desire to make a dif­fer­ence but not so good at moti­vat­ing real action. But he says the ele­va­tion effect is pow­er­ful nonethe­less. “It does appear to change peo­ple cog­ni­tively; it opens hearts and minds to new pos­si­bil­i­ties. This will be cru­cial for Obama.”

Procrastinating Again?

Pro­cras­ti­na­tion is not a time-management prob­lem. It’s a com­plex prob­lem involv­ing per­son­al­ity, sit­u­a­tions and moti­va­tion. Every­one occa­sion­ally pro­cras­ti­nates, 15 to 20 per­cent of adults rou­tinely put off activ­i­ties that would be bet­ter accom­plished right away, and a whop­ping 80 to 95 per­cent of col­lege stu­dents have a pen­chant for post­pone­ment. Trisha Guru cov­ers con­tem­po­rary views on and advice for kick­ing the pro­cras­ti­na­tion habit.

Technology Traps

I have a love/hate rela­tion­ship with tech­nol­ogy, much of my tur­moil stems from the fact that I do not always have the lux­ury of say­ing no or even, let me think about it, before it becomes a tech­nol­ogy I depend on. This is a symp­tom of what Peter Crabb calls tech­no­log­i­cal traps, con­se­quences of every­day deci­sions to use tech­no­log­i­cal devices that make us feel good when in fact these devices are not good for us or the planet at all:

With the help of human enthu­si­asts and enablers, tech­nol­ogy cre­ates its own self-affirming ide­ol­ogy. It is widely believed that tech­nol­ogy is infal­li­ble. Tech­nol­ogy must not be ques­tioned or crit­i­cized. Human needs are sub­or­di­nate to the needs of devices and sys­tems. If some­thing goes wrong, it must be due to “human error.” The solu­tion to technology-induced prob­lems is always more and bet­ter tech­nol­ogy. In fact, every arena of human activ­ity is always improved when the lat­est, most com­plex tech­nolo­gies are applied. As a con­se­quence of the ascen­dancy of tech­nol­ogy, humans have become demeaned and pow­er­less – second-class cit­i­zens in their own societies.

The Ambassadors

The Ambas­sadors by Hans Hol­bein the Younger, is a por­trait of two French­men, one an ambas­sador to the court of King Henry VIII, the other a cleric. They are lean­ing on a cup­board with dis­plays — on the upper shelf objects refer­ring to the heav­ens; on the lower shelf, objects indi­cat­ing their earthly inter­ests. There are many hid­den mes­sages and mean­ings in this work, notes Don­ald Clark, includ­ing the large anamor­phic skull, which he has cho­sen to inter­pret in terms of learn­ing. The paint­ing reveals a 1533 cur­ricu­lum of the emerg­ing split between the voca­tional arts and acad­e­mia, and the retreat­ing role of reli­gion, a cur­ricu­lum whose influ­ence is clearly still felt some 500 years later.

Group Think

The explo­sion of online mate­ri­als has two, some­what con­tra­dic­tory effects. The scope of avail­able infor­ma­tion expands, remark­ably so; but as a con­se­quence, the infor­ma­tion needs to be fil­tered some­how, and the fil­ter is either reverse chrono­log­i­cal order or popularity:

Many Inter­net users cus­tomize their con­sump­tion of news sources and other infor­ma­tion in a way that fos­ters polar­iza­tion. This, it could be argued, has ele­ments both of the nar­row­ing effect and the long tail. Amer­i­cans seek out sources that reflect their per­sonal beliefs, con­sis­tent with Anderson’s vision. But, akin to the nar­row­ing Evans observes, large groups — lib­er­als and con­ser­v­a­tives — con­verge on dif­fer­ent ref­er­ence points, result­ing in mutu­ally unrec­og­niz­able ver­sions of real­ity. The com­mon les­son of all of these phe­nom­ena is to be cog­nizant that the tools we use affect us in ways we may not fully appre­ci­ate. We should always be search­ing, the find­ings sug­gest, for new ways to search.
