Lacking knowledge

Tue, 2012-06-26 12:10 -- John Hawks

Sandra Blakeslee discusses a new book about the process of science: Ignorance: How It Drives Science, by Stuart Firestein ("To Advance, Search for a Black Cat in a Dark Room").

Dr. Firestein got the idea for his book by teaching a course on cellular and molecular neuroscience, based on a 1,414-page textbook that, at 7.7 pounds, weighs more than twice as much as a human brain. He eventually realized that his students must think that pretty much everything in neuroscience is known. “This could not be more wrong,” he writes. “I had, by teaching this course diligently, given the students the idea that science is an accumulation of facts.

“When I sit down with colleagues over a beer at a meeting, we don’t go over facts,” Dr. Firestein writes. “We don’t talk about what’s known. We talk about what we’d like to figure out, about what needs to be done.”

Lurking here is some insight about the process of deciding who gets to do what (and gets funded for it). To be willing to grant money to a project, there is a trade-off between admitting that the answer is unknown, and admitting that the process has a good likelihood of successful outcome. Ignorance has a dual role here: the grantor must admit a certain amount of ignorance, while the prospective grantee must define ignorance in an incredibly narrow way (and ideally demonstrate that it's not ignorance after all).

In some sense, becoming successful at funding your work requires solving an intricate communication problem where the subject is ignorance.

I'm a little concerned about the idea (mentioned in the review) of an entire semester-long course titled, "Ignorance". Don't the students get enough about ignorance after one or two class sessions?

Neandertals

For years, I've worked on their bones. Now I'm working on their genes. Read more about the science studying these ancient people.

Denisova

From a finger bone of an ancient human came the record of a completely unexpected population. My lab is working on the science of the Denisova genome.

Acceleration

The advent of agriculture caused natural selection to speed up greatly in humans. We're uncovering some of the ways that populations have rapidly changed during the last 10,000 years.

Malapa

Just outside Johannesburg, the Malapa site is producing some of the most exciting finds in human evolution. This site is the headquarters of the Malapa Soft Tissue Project.
