My latest Mind and Matter column for the Wall Street Journal:
If, as I argued last week, scientists are just as prone as
everybody else to confirmation bias to looking for evidence to
support rather than test their ideas then how is it that science,
unlike cults and superstitions, does change its
mind and find new things?
The answer was spelled out by the psychologist Raymond Nickerson
of Tufts University in a paper written in 1998: "It is not so much
the critical attitude that individual scientists have taken with
respect to their own ideas that has given science the success it
has enjoyed... but more the fact that individual scientists have
been highly motivated to demonstrate that hypotheses that are held
by some other scientist(s) are false."
latest Mind and Matter column in the Wall Street Journal:
There's a myth out there that has gained the status of a cliché:
that scientists love proving themselves wrong, that the first thing
they do after constructing a hypothesis is to try to falsify it.
Professors tell students that this is the essence of science.
Yet most scientists behave very differently in practice. They
not only become strongly attached to their own theories; they
perpetually look for evidence that supports rather than challenges
their theories. Like defense attorneys building a case, they
collect confirming evidence.

If all goes well next month, Curiosity, NASA's latest mission to
Mars, will land in the Gale crater, a 3.5-billion-year-old,
96-mile-wide depression near the planet's equator. Out will roll a
car-size rover to search for signs of life, among other things. It
will drill into rocks and sample the contents, using a mass
spectrometer, a gas chromatograph and a laser spectrometer.
In the unlikely event that the project finds evidence of life,
then what? In particular, who is in charge of deciding what we
should do if we encounter living Martian creatures?
The Times published my op-ed on banking reform:
It is not yet clear whether the current rage against the banks
will do more harm than good: whether we are about to throw the baby
of banking as a vital utility out with the bathwater of banking as
a wasteful casino. But what is clear is that the current mood of
Bankerdämmerung is an opportunity as well as a danger. The fact
that so many people agree that some kind of drastic reform is
needed, all the way along a spectrum from Milibands to mega-Tories,
might just open the window through which far-reaching reform of the
financial system enters.
All the actors involved bear some blame. First, investment
bankers and the principals in financial companies that cluster
around them have trousered an increasing share of the returns from
the financial markets, leaving less for their customers and
shareholders, while getting "too big to fail", so passing their
risks to taxpayers.
Two rival designs of plant biochemistry compete to dominate the
globe. One, called C3 after the number of carbon atoms in the
initial sugars it makes, is old, but still dominant. Rice is a C3
plant. The other, called C4, is newer in evolutionary history, and
now has about 21% of the photosynthesis "market." Corn is a C4
plant. In hot weather, the C3 mechanism becomes inefficient at
grabbing carbon dioxide from the air, but in cool weather C4 stops
working altogether. So at first glance it seems as if global
warming should benefit C4.

As I cowered in my parked car in a street in Newcastle last
Thursday, nearly deafened by hail on the roof of the car, thunder
from the black sky and shrieking girls from the doorway of a
school, a dim recollection swam into my mind. After inching back
home slowly, through the flooded streets, I googled to refresh the
memory. On 23 March this year, the Meteorological Office issued the following prediction:
"The forecast for average UK rainfall slightly favours
drier-than-average conditions for April-May-June as a whole, and
also slightly favours April being the driest of the 3 months. With
this forecast, the water resources situation in southern, eastern
and central England is likely to deteriorate further during the
