Clayton Christensen’s Jobs-to-be-done Theory

I have written much more about Clayton Christensen’s Jobs-to-be-done framework over at the FullStory blog:

Clayton Christensen (along with a few other co-authors) is soon releasing a book called Competing Against Luck that will go more in-depth on Christensen’s “Jobs-to-be-done theory,” which is a way to reframe product design and product selling away from fallacious, post ergo hoc propter hoc data and towards first principles.

Dunbar’s Number, Broken Social Networks, and Back Scratches

My brother passed on an article in The New Yorker from a couple weeks back titled The Limits of Friendship. It’s an exposition on Oxford anthropologist Robin Dunbar’s discovery that humans organize into social groups that tend to range from 100-200 people, with the average—150—being an optimal rule of thumb. This is known as Dunbar’s number.

The discovery was made through observing the correlation between the size of an animal’s frontal lobe whereby the larger the frontal lobe (or smaller), the larger the social group size for that animal. Applying this understanding to human brains, “Judging from the size of an average human brain, the number of people the average person could have in her social group was a hundred and fifty.”

Digitally Isolated

I keep thinking about being digitally isolated.  What is “digital isolation?” In a nutshell: today we are more connected to anyone/everyone than at any point in history yet (paradoxically) we feel ever more alone. Stranger still, it seems we have chosen this as our preferred mode of existence.  There’s even a joke about it: there are nine ways to reach me on my phone without talking to me; pick one of those.

Raw Milk Safer than Salad

A little background

Some of you know that when we our second daughter Raya was around 5 or 6 months old, I started “homebrewing” her formula based on a recipe for raw cow’s milk based baby formula I found at The Weston A. Price Foundation website.  I made this formula for Raya for about six months before we just started giving her straight raw cow’s milk.  Today, and ever since (some seven months later), both our girls continue drinking raw cow’s milk.  I’ll circle back and talk more about that in a minute.

Why I Didn’t (And Don’t) Vote

Folks who know me know I don’t vote. Many roll their eyes at this decision. Others awkwardly skirt around it preferring to avoid asking why I don’t vote (I don’t usually go into why unless prompted). And most people just assume I do vote. Of all my friends and family and coworkers, I’m unsure how many have given a second thought to the act.

Do they simply accept the rhetoric that it’s some moral imperative to vote? That it’s a duty? That it’s a right you must exercise to preserve?

I don’t know.

Weight Gain from Forced Overeating has Limits

It seems the only things I can find time to blog on these days are posts from Peter of Hyperlipid. I’ve whittled down the number of blogs I follow that cover nutrition — just not enough time in a day — but Peter’s is fun to read if not a bit “in the weeds.” Peter can go in depth on scientific studies and the chemistry of metabolism, mitochondria, insulin, etc., but he almost always has a way of distilling that information in a way that I can not only make sense of it, but take away some insight. If you are interested in what drives obesity, eating, etc., Peter’s blog is one of the best around. And if you’re not buying the whole “Reward Hypothesis” of obesity that is being trumpeted by Stephen Guyunet (or are at least skepitcal of it — I think Guyunet is off track here; Todd Becker’s theories make a more holistic, coherent case that strings together the behavioral aspects of obesity like reward and the insulin — required reading of his here and here and here).

Compensating for Broken Fat Cells

When it comes to reading about the metabolic effects of eating a high fat diet (With low fat and low carbohydrate, in turn), I turn to Peter’s wonderful Hyperlipid. I was catching up on Reader the other day when I saw this post about broken mice. It’s a bit esoteric so be warned, but there’s an idea therein that I find particularly interesting — it pertains to mice with broken metabolisms.

Gamers Solve Problem that Dogged Researchers for Decades

“Online gamers have achieved a feat beyond the realm of ‘Second Life’ or ‘Dungeons and Dragons’: they have deciphered the structure of an enzyme of an AIDS-like virus that had thwarted scientists for a decade.”

Awesome. The takeaway I see in this approach is evocative of self-experimentation. Gamers are basically lots of little experimenters. Perhaps gamers succeeding where scientists had failed for a decade is less about playing a (purposeful) game for fun and more about simply having enough people iterating on the problem with a basic incentive to succeed (it’s fun).
