Six Italian scientists and an ex-government official have been sentenced to six years in prison over the 2009 deadly earthquake in L'Aquila.
A regional court found them guilty of multiple manslaughter.
Prosecutors said the defendants gave a falsely reassuring statement before the quake, while the defence maintained there was no way to predict major quakes.
The 6.3 magnitude quake devastated the city and killed 309 people.
It took Judge Marco Billi slightly more than four hours to reach the verdict in the trial, which had begun in September 2011.
The seven - all members of the National Commission for the Forecast and Prevention of Major Risks - were accused of having provided "inexact, incomplete and contradictory" information about the danger of the tremors felt ahead of 6 April 2009 quake, Italian media report.
This is what I call the layman's "CSI" view of science, which assumes that certainty is possible in analyzing and forecasting complex systems. I am not going to blame the victim here, but I will note that scientists have to some extent made this situation far worse by insisting that they have levels of certainty they do not have, particularly in highly charged political debates (e.g. economics and climate).
Harvard physicist Luboš Motl argues it will give scientists roughly the same incentives doctors have in areas with lots of malpractice suits:
The verdict de facto lionizes crackpots who were screaming that there had to be a large earthquake and they just happened to be right in that case – while isomorphic and sometimes the very same crackpots are wrong in 99.9% of other cases in which they cry wolf – and it condemns the scientific method. They are wrong in 99.9% of cases because their predictive framework has nothing to do with science – it's all about a psychopathological paranoia – but even a broken clock is right twice a day.
The lesson for the scientists is clear: If you are a scientist who is qualified in a discipline that has implications for the safety of people, you must always recommend precautionary measures to be taken even if you conclude that the probability that something bad will happen is tiny. Italy may expect much more hysteria in various similar science-related situations than it has had so far because a court has declared a war on everyone who is honest and balanced.
Can you imagine that this sick logic would be applied e.g. to surgeons? Surgeons could spend 6 years in prison after every death of a patient whom they or others were optimistic about. It's just insane. People sometimes die, natural catastrophes sometimes occur, and it's just impossible to identify a human culprit in most cases. Only if a professional makes a mistake in which he or she has demonstrably violated some established and functional rules to reduce the risk – and whether or not this was the case may only be determined by another expert – he or she could be considered co-responsible for the deaths.
