You can’t spell “prescience” without “science”
On April 6, 2009, there was an earthquake in L’Aquila, Italy; 308 people were killed. Six days before that, on March 31, there had been a meeting of the Commissione Grandi Rischi (“Major Risks committee”) in L’Aquila, which concluded that a major quake was unlikely. Members of the committee were indicted the following year on manslaughter charges for not warning the citizens of L’Aquila to evacuate. This story contains an important lesson for any scientist, or at least some important food for thought. What exactly is our responsibility to society, when it comes to predicting the future?
Why empiricism will always be imperfect
A new year is upon us, and that’s always a great time to clean out the skeletons in your closet. So without further ado, let’s take a look at Jonah Lehrer’s explanation of “the decline effect” (published in The New Yorker last month). Lehrer describes this odd phenomenon whereby statistical significance of previous scientific findings seems to decrease with age, as we get further and further away from the time that it was initially reported in literature.
As any scientist can tell you, the holy grail of an experiment is a low p-value, a statistical measure that tells whether your findings are indicative of an actual effect, not just randomness and chance. This sounds fairly straightforward – of course we want to find things of actual importance, rather than being lulled into a false discovery by arbitrary data – but it turns out to be much hazier than a simple “yes” or “no.”
Shedding light on the supposed link between MMR and autism

As you may have noticed in the past few months (if not years), there is quite a bit of concern about the possible link between autism and vaccinations. If you were to look at almost any properly carried out independent study, you’d find that most of these allegations are completely ridiculous. Nevertheless, sensational claims seem to have a knack for outshining the factual evidence that contradicts them. The autism/vaccination “link” has caused a number of parents to intentionally avoid vaccinations for their children, resulting in a number of unnecessary deaths, including the recent outbreak in whooping cough in California.
It all started with a paper written by Andrew Wakefield in 1998. In the paper, he describes a number of children who had recently undergone vaccination for MMR (measles, mumps and rubella) and supposedly began showing signs of autism shortly thereafter. The author suggested that the MMR vaccine was causing these children to develop their symptoms.
Twelve years and who knows how many un-vaccinated children later, we finally get…
Survival of the kindest
Have you heard the latest news out of the Greater Good Science Center? What’s that, you say? You didn’t know that UC Berkeley had a Greater Good Science Center? In a town whose reputation is already firmly in the “touchy-feely” category, there is a group of psychologists and sociologists studying how to make people happier. The video explains it all:
As a former would-be sociologist, I feel a fond nostalgia for the notion of compassion as a tonic for society’s ills. The main goal of the researchers at Greater Good is to show that kindness and cooperation are better survival strategies than competition and selfishness.
