Computer says "no"

Every November, the Royal Society and the French Académie des sciences give out a prize to a scientist who has discovered how to do something innovative with computers. Naturally, it has to be a useful innovation. The 45 employees at the Department for Work and Pensions who have been disciplined after using their computers for shopping, pornography and "unauthorised downloading" need not apply.

It's not just government employees who abuse their computers. In May 2008, the head of the Max Planck Institute for Mathematics warned that
City traders were doing it, too. He argued that their lazy acceptance of whatever the computers said would lead to financial disaster.

No one understands "garbage in = garbage out" better than the scientists who have learned that their reputation can be ruined by placing unquestioning trust in the printout. To take a slightly ridiculous example, researchers at the UK's National Physical Laboratory have just fixed a 20-year-old problem in the official computer model of the shape of the outer ear. It was created to define a quality standard for the performance of headphones and mobile phones (you are forgiven for not realising how useful scientists can be). The input scan for the computer model was done at too low a resolution, however, and manufacturers have since been filling in the gaps in ways that reflect best on their brand. It ain't necessarily so, just because the computer says it is.

Innovation in scientific computing has done some wonderful things. It has allowed us to model the heart, giving us insight into how drugs affect cardiac rhythms and how heart attacks develop. It enables us to analyse medical images more accurately, providing earlier diagnosis of cancers. Thanks to computer models, we can see why misfolded protein gives rise to cystic fibrosis and predict the path of dangerous epidemics.

But in every case, the computer's predictions or declarations have to be checked against what scientists can observe happening.

In science, the only credible guide is real-world experiment. Across at the Channel, the French use a slightly different word for "experiment" - expérience. That is no coincidence: it emphasises that scientists learn from trial and realisation. Think, for example, of what the British economist John Maynard Keynes called the "folly and injustice" of the UK government's 1931 plan to beat the recession. The measures, which in effect shut down economic activity, didn't work, and led to the abandonment of the gold standard.

The gold-standard scientific approach - experiment or experience - suggests there is no reason to believe that the same approach to beating recession will work now, either - whatever the printout from the Treasury's computer might say.

Goldsmiths diversity officer Bahar Mustafa receives court summons in wake of “#KillAllWhiteMen” outcry

Mustafa will answer charges of "threatening" and "offensive/ indecent/ obscene/ menacing" communications.

In May this year, Bahar Mustafa, then diversity officer at Goldsmiths, University of London, posted a Facebook message requesting that men and white people not attend a BME Women and non-binary event. There was an immediate backlash from those also enraged by the fact that Mustafa allegedly used the hashtag #KillAllWhiteMen on social media. 

Today, Mustafa received a court summons from the Metropolitan Police to answer two charges, both of which come under the Malicious Communications Act 1988. The first is for sending a "letter/communication/article conveying a threatening message"; the second for "sending by public communication network an offensive/ indecent/ obsecene/ menacing message/ matter".

It isn't clear what communciation either charge relates to - one seems to refer to something sent in private, while the use of "public communication network" in the second implies that it took place on social media. The Met's press release states that both communciations took place between 10 November 2014 and 31 May 2015, a very broad timescale considering the uproar around Mustafa's social media posts took place in May. 

We approached the Met to ask which communications the summons refers to, but a spokesperson said that no more information could be released at this time. Mustafa will appear at Bromley Magistrates' Court on 5 November.
