We Think Too Fast
By Shlomo Maital

We think too slow. This is a conclusion of a lovely article in the New York Times by Carl Zimmer. *
Streaming a high-definition video takes about 25 million bps (a ‘bps’ is bit per second, and ‘bib’ is a unit of information, say, zero or one). The typical download rate, engineers have found, in a US household is 262 million bps.
OK, that’s the Internet. Now, how fast is the ‘download’ rate in the human brain? How fast does information flow from our brain to our bodies?
Caltech neuroscientist Markus Meister has published a study in Neuron, according to Zimmer, and speaks about the endless hyperbole about how incredibly complex and powerful the human brain.
Actually, it’s pretty slow, Meister says. He and colleagues estimate the flow of information ‘downloaded’ from the brain to the body is…. “just 10 bps”. Ten bits per second. The title of their article? “The unbearable slowness of being”. This is a clever play on the 1984 novel by Czech writer Milan Kundera, The unbearable lightness of being. At 10 bps, you couldn’t begin to download even a silent black and white movie from 1920.
Just 10 bps. Not even enough to download a high definition vide. Huh!
Let me make an opposing argument. Even 10 bps is far too fast. Have you ever said things you wish you hadn’t? Yes? Many times? Reacted too fast?
Radio stations have a kill button. What you hear is delayed by a second or two, before it is aired. This is just in case someone calling in uses a profanity, not allowed by FCC rules, and the host hits the kill button to avoid broadcasting it.
I find I need a delay/kill button. Think something. Think if it really needs to be said. Is it hurtful? False? Emotionally disturbing? Hit the delay before you send it out into the air. I wish I had done this more often – before I invented my own ‘kill button’ — think it, listen to it as if you are saying it, and only then, actually say it.
No, scientists, the brain is not too slow. If anything, it may be too fast. Slow it down a bit. Believe me – it will keep you out of hot water, especially with your partner or spouse.

Jerome Bruner: Possible Worlds
By Shlomo Maital
Jerome Bruner just passed away. He was 100 years old.
Bruner changed forever the way we see the world and the way we understand human thinking. As a pioneer cognitive psychologist, he helped us rethink the mind as what he calls a “hypothesis generator” – the human can envision “possible worlds” (the title of one of his most famous books.
As a child he recalls being influenced by one of his teachers, Ms McNamara, who taught him that “the world is an open question”. And that is how Bruner viewed psychology. If you deal only with what exists, he noted, then psychology has nothing to do with life. In giving advice to young psychologists, he urged them, “get out of your office and get into the real world.”
His older sister Alice influenced him strongly. She was smarter than me, he recalls, and asked him, “why are you always guessing?” But Bruner saw the mind as a “hypothesis generator” – as something that asks questions, rather than spews out answers.
He had a lifelong love of sailing. Sailing for him was a metaphor of life. You sail in an unpredictable environment, when the wind can change at any moment, and you have the illusion of control, adjusting the sails, etc., but it’s only an illusion.
I personally embrace Bruner’s landmark article The Narrative Construction of Reality (1991), because I’ve come to believe, as Bruner showed, that we understand reality by telling ourselves stories – about ourselves, about others, about how things work. And some of those stories are fiction, made-up, “possible worlds”, this is called creativity and entrepreneurship. Entrepreneurs make up a possible world and then make it happen.
My colleague Arie Ruttenberg defines creativity as “widening the range of choices”. That is, imaging new possibilities, possible worlds. Bruner supports this.
From childhood, Bruner had limited vision. But it never hampered him. He brought common sense and a spirit of rebellion to his discipline, and embraced all other disciplines that he felt were related. We will miss him.
