How much can the brain really hold?

Your brain is a great place to have ideas, but a terrible place to manage them. -David Allen

A key principle within GTD is creating a system external to your mind–if you want the system to be seamless.  In fact, there’s a good chance if you’re trying to hold more than about 7 things in your mind at once, you’re dropping things all the time.  And guess what?  Your brain doesn’t care if what you dropped was important or not important, urgent or not urgent, about buying bread on the way home from work or solving world hunger.   If you’re trying to balance more than 7 things in there at any given time, something’s gonna drop.

I’m sure I’ll remember…

“The short-term memory part of your mind–the part that tends to hold all of the incomplete, undecided, and unorganized “stuff”–functions much like RAM on a personal computer. Your conscious mind, like the computer screen, is a focusing tool, not a storage place. You can only think about 2 or 3 things at once.

- David Allen (p.22 of Getting Things Done)

Why We Like New Things; or why I have to try out every new GTD program.

This came in from one of our contributors, Dr. Lynn O’Connor.

I’m one of those unfortunate people who loves trying out new software for my GTD system. So far, I’ve always gone back to the online, tried and true, Vitalist (www.vitalist.com ) for contexts/next action lists (projects too if needed).  But that hasn’t stopped me from doing that experimenting or “tweaking” as some optimists call the time I waste fooling around with new organization/GTD programs. I’ve made this lame excuse: “Every time I enter my next action data into a new program it allows me to review everything in greater detail than I do in a weekly review.” That was as far as I got in explaining my sneaky kind of procrastination behavior. It began to feel even shameful to wile away a whole afternoon exploring some new program.

I felt a lot better about my “try new software”  habit when I read a report from the latest issue of Neuron, as described in New Scientist. In an experiment, researchers demonstrated that our love of adventure and novel objects, is based upon our hard wiring, we could say on our basic nature.  It seems that every time we explore, investigate, try out or learn something new, the reward center of our brain starts firing, much as it would if we were expecting to win a lottery, a card game, a horse race  or any kind of competition. My guess is trying out new GTD software is yet another way I flood my restless brain with dopamine.

This fact about how we’re naturally wired is long known in business and advertising. It’s why companies may put out a product with absolutely no changes, except for the packaging. People buy the new, even if it is more expensive and less convenient. We all fall for something novel. So now, maybe I can get off my case about trying out every new GTD program.

GTD Times – Kluge and GTD

kluge_event_full.jpgEditor’s Note: We’ve had an incredible response to the request for contributor’s with a cognitive sciences background. Several notable individuals have very kinds offered to author posts that deal with questions of the brain that I believe are of great importance with respect to helping us understand why we do what we do, why GTD works where other systems fail, and how to get the most out of our own curious intellectual circuitry.

One such contributor, Jennifer George has authored the post below and will begin her contributions to GTDtimes with a series of posts based upon the ground-breaking book, Kluge, authored by Gary Marcus.

Jennifer George is a productivity geek and Web addict who writes the blog Lifemuncher. In the real world, she is a fundraiser for UCLA and a graduate student in clinical psychology at Capella University.

Gary Marcus’s book, Kluge: The Haphazard Construction of the Human Mind, examines the strange collection of more or less ancient systems that makes up the modern human brain. As he explains in chapter one:

“Measured nucleotide by nucleotide, the human genome is 98.5 percent identical to that of the chimpanzee. This suggests that the vast majority of our genetic material evolved in the context of creatures who didn’t have language, didn’t have culture, and didn’t reason deliberately. This means that the characteristics we hold most dear, the features that most distinctly define us as human beings — language, culture, explicit thought, must have been built on a genetic bedrock originally adapted from very different purposes.”

The word Kluge is an engineering term, and means an inelegant solution that works, but not in the best way possible because of historical and/or environmental constraints. Since our brains evolved over millions of years, building on existing systems rather than scrapping them and starting fresh, we find ourselves with a brain that’s like a marvelous Rube Goldberg device, held together with duct tape and chewing gum. It’s great at things that helped us survive and reproduce on the African savannah, and not quite as good at things related to language and abstract thought, which evolved much more recently.

According to Marcus, the human brain is primarily interested in helping you survive – noticing predators and food sources and finding potential mates. Figuring out the next step on that computer program you’re writing? Evaluating whom to vote for for president? Not so much.

The book is a fascinating and humbling overview of the evolutionary forces that built the modern brain and the resulting strengths and weaknesses that constrain and influence the way we live. Much of what Marcus describes is directly relevant to GTD and productivity, and could give us insights on better ways to do things. In a series of posts, I will be examining his findings on and trying to apply them to the life of a modern office drone. Look for the first one, on memory, later this week.
