Transparency pressures
From Adam Phillips:
“If sanity is defined by how intelligible we are to each other, then we are living under tremendous pressure to be as transparent as possible. The problem may not be always or only how to better understand each other (and ourselves), but actually what we should do with whatever we don;t understand.”

Thanks Alexandre
Not teachers but ‘co-learners’
From Will Richardson:
“What if we assessed teachers in large part on their abilities to create and consume content effectively as co-learners and co-creators with their students, and to share that work in transparent ways?”

The job of the brain is to make decisions. These decisions depend on handling signals with extreme precision…. Remarkably, the closer scientists look at the brain, the more noise they discover.

How information can harm decisions
Additional knowledge of the minutiae of daily life can be not just useless, but actually harmful to us when we make decisions.
From thinking to iterating
Last June, Alex Iskold wrote a piece about the new age of continual partial attention:
There will never be less information, there will always be more of it. Much more. The sooner we recognize it and prepare for this change, the easier it will be for us to embrace this brave new world. The age of Continuous Partial Attention has arrived and it is here to stay.
As Linda Stone defined CPA
“With [continuous partial attention], we feel most alive when we’re connected, plugged in and in the know. We constantly SCAN for opportunities - activities or people - in any given moment. With every opportunity we ask, “What can I gain here?”
Alex also noted that “these days we replace the deep thinking with rapid iteration.”

And he went on to say that this replacement “is not necessarily a bad thing!”
Fire Hydrants
In one famous experiment, the Harvard psychologist Jerome Bruner and his student Molly Potter had people identify the object shown in a slide as it gradually came into focus. If viewers made an incorrect hypothesis early on, they tended to persist with it, and had trouble identifying the object even as it became sharp.

Thanks Mike
Moral? According to NNT, it’s this:
“The more information you give someone, the more hypotheses they will formulate along the way, and the worse off they’ll be. They see more random noise and mistake it for information.
The problem is that our ideas are sticky: once we produce a theory we are not likely to change our minds. So those who delay developing their theories are better off … Remember that we treat our ideas like possessions and it will be hard for us to part with them.
Remember that we are swayed by the sensational. Listening to the news on the radio every hour is far worse for you than reading a weekly magazine, because the longer interval allows information to be filtered a bit.”
NNT goes on to describe Paul Slovic’s experiment with bookmakers. First, he showed bookmakers 88 variables in past horse races and asked them to choose the most useful ones. Then he gave them the ten most useful variables and asked them to predict the outcome of races. Then he gave them ten more variables and asked them to predict again.
The increase in the information set did not lead to an increase in their accuracy; their confidence in their choices, on the other hand, went up markedly. Information proved to be toxic“
More is not always better
It’s probably a little simplistic to think that these research caveats apply to all information. They apply to situations where you have to predict or forecast. That said, the caveats do seem to imply various things:
- The iterative mode in the table above isn’t wholly accurate. It can actually lead to more costly mistakes (through the overconfidence it affords). The partial information is a given for both deep thinking and iterative mode, the real difference is frequency of updates. And iterative mode actually hinders the imagining alternative possibilities. We tend to stick with our first possibility and then not be able to ditch it in favour of the fire hydrant.
- The iterative mode assumes that the brain is an information processing machine. My guess is that this is idealised but wrong. The brain seems much more like a meaning making engine.
Anyway, as far as RSS readers go, I’m going to ditch some of my BBC news feeds , and (not that he does this) have a think about adopting/adapting Ton’s people oriented approach. And I’m going to renew my subscription to The Week
Teaching Doubt
From NNT:
My biggest problem with the educational system lies precisely in that it forces students to squeeze explanations out of subject matters and shames them for withholding judgement, for uttering the “I don’t know”. Why did the Cold War end? Why did the Persians lose the battle of Salamis? Why did Hannibal get his behind kicked? Why did Casanova bounce back from hardship? …
I am not saying causes do not exist; do not use this argument to avoid learning from history. All I am saying is it is not so simple; be suspicious of the “because” and handle it with care, particularly in situations where you suspect “silent evidence”.

Government Collaboration
This is (generally) good news.
“Cabinet Office Minister Tom Watson has announced a new Task Force, headed by Richard Allan, to take forward proposals in the Power of Information report.”
It does make a government api seem a long way off though. There’s a risk that a few banner community services get chosen and funded by the government at the expense of others, and I hope that’s avoided.
