Can Curiosity Kill The Sciences?

I am in the middle of a series of posts about scientific method, so this seemed very much to the point. especially, how to avoid acting like a Doctor Authority Figure Type (DAFT), while still defending the value of expert evidence over anecdote (and, I would add, over ideology)?

The Grumpy Geophysicist

There’s a book out there that seems to be attracting lots of lightning bolts (Steven Pinker’s Enlightenment Now!).  GG is not interested in reading or discussing that, per se. It sounds as though logic and empirical observation got confused in there (they are not the same). What got his attention was one of the responses by Ross Douthat of the New York Times, who essentially argues that smugness by those who purport to know better will stifle real science. The nub of the argument is in this quote:

I’m reasonably confident that both of the stranger worlds of my childhood, the prayer services and macrobiotic diet camps, fit his definition of the anti-empirical dark. And therein lies the oddity: If you actually experienced these worlds, and contrasted them with the normal world of high-minded liberal secularism, it was the charismatic-religious and “health food” regions where people were the…

In praise of fallibility; why science needs philosophy, with examples from astronomy and chemistry

[Adapted from 3 Quarks Daily] More recent strata lie on top of older strata, except when they lie beneath them. Radiometric dates obtained by different methods always agree, except when they differ.  And the planets in their courses obey Newton’s laws of gravity and motion, except when they depart from them.

As Isaac Asimov reportedly said, “The most exciting phrase to hear in science, the one that heralds new discoveries, is not ‘Eureka!’ [I have found it], but ‘That’s funny …’ ” And there is nothing that distinguishes so clearly between the scientific and the dogmatic mindset as the response to anomalies. For the dogmatist, the anomaly is a “gotcha”, proof that the theory under consideration is, quite simply, wrong. For the scientist, it is an opportunity. If an idea is generally useful, but occasionally breaks down, something unusual is going on and it’s worth finding out what. The dogmatist wants to see questions closed, where the scientist wants to keep them open. This is perhaps why the creationist denial of science can often be found among those professions that seek decision and closure, such as law and theology.

The rights and wrongs of falsification

Karl Popper

Dogmatists regularly invoke the name of Karl Popper, and the work he did in the 1930s. Popper placed heavy emphasis on falsifiability, denouncing as unscientific any doctrine that could not be falsified. Freud’s theories, for example, Read the rest of this entry
