Tech Tent: fake news, algorithms and listening gadgets

In a generation of faux news and Presso Graphy  opportunity records, how can scientists re-have interaction with the general public and make sure they may be respected and understood? That’s a massive subject matter at the Cheltenham Science Festival from which this week’s edition of Tech Tent comes.
We additionally discuss the growing significance of algorithms in our lives – and ask whether or not we must be concerned that our devices are paying attention to us.
Science underneath siege
The freshest price ticket at the Cheltenham Science Festival turned into for a debate at the fake information phenomenon hosted by using the comedian, and former theoretical physics scholar, Dara Ó Briain.
He told a hilarious story approximately a faux information report of his demise after a car driven with the aid of his chauffeur plunged right into a Dublin ravine – who knew that town’s geography changed into so perilous?
But the controversy hastily turned serious when Nasa’s former leader scientist Ellen Stofan talked about that a decline in faith in science in areas like vaccine protection and weather change ought to have profound results for the planet.
Expanding on this in an interview for Tech Tent, Dr. Stofan instructed me those had been lifestyles and death problems, and public misconceptions and distrust of scientists was a remember of the real subject.

She’d observed President Trump’s decision to withdraw from the Paris Agreement on weather “extremely disappointing”, and changed into involved that the public changed into now not aware that all the principal clinical establishments were agreed that climate alternate turned into actual and turned into caused by humans.
And she blamed the internet – and the important tech organizations – for spreading misinformation: “There’s honestly a profit cause in spreading incorrect information…Human beings try and discover information that enhances their opinion – and on the internet, you can discover just about any statistics.”


She said that, in looking to appear independent, the tech firms had helped folks who had been looking to spread untruths, and they had to suppose carefully about placing such information available without making its veracity clear to human beings.
Do Algorithms Know Best?
“A laptop you make a decision on our behalf for us – or with us.” I had asked Jeni Tennison for a simple definition of a set of rules – and the leader executive of the Open Data Institute got here up with a quite good one.
Computers absorbing a torrent of information from social media and the internet of things are being programmed to make ever more decisions – from what you pay to insure your automobile to where you should move for dinner. But now extra questions are being asked approximately how those algorithms paintings and whether they are constantly true for us.


Jeni Tennison conceded there was a chance that they have been constructed to mirror a Silicon Valley mindset – and stated programmers anywhere needed to sit returned and consider the effect on our lives.
She turned into debating algorithms with Hetan Shah of the Royal Statistical Society. He’s largely constructive, seeing those facts-pushed recipes as improving regions like poverty reduction by using mapping crop yields and predicting famine.

But he sees a real risk of biased algorithms feeding off biased records: “The regulations which have labored to this point have been stretched to breaking point in an international wherein your fridge and your vehicle are passing round statistics right away.”
He indicates that there will be a set of smart individuals who could begin considering problems consisting of whether or not a driverless car’s algorithm ought to continually favor the protection of a motive force in the occasion of an accident.
Are your gadgets listening?
This week Apple unveiled a wireless smart speaker the HomePod, an alternatively belated rival to the Amazon Echo and the Google Home, although one that claims superior audio best.
But over again it seems we are being requested to invite a listening device into our houses.
At a debate on listening gadgets in Cheltenham, I located an audience quite wary of this phenomenon – one man requested what Orwell would have the notion of an international where we virtually paid to be spied on.

Audio sign specialist Professor Mark Plumbley from the University of Surrey explained that the devices have been normally best recording after they were alerted via a wake phrase which includes “Alexa” – however after that, your voice information becomes avoiding into the cloud to be processed.
Security expert Dr. Jason Nurse from Oxford University stated we had to ask how lengthy those various services have been retaining recordings of what we said while talking to our devices. But his actual subject turned into what befell if they have been taken over with the aid of criminals: “If hackers got control of those gadgets then they might record all the time – and that’s a pretty massive situation.”
Mark Plumbley is skeptical about the principle held with the aid of many that each one forms of on-line services are eavesdropping on us and then sending us ads reflecting our overheard conversations.
But he cautions that each one forms of apps now ask for permission to use the cellphone’s microphone and we have to be cautious earlier than agreeing.
Voice manipulate has been the recent new fashion in home gadgets for pretty some time, and if the spate of TV ads for the Amazon Echo and Google Home are something to head by, the tech industry is convinced they may be successful with clients.
But perhaps it is time to assume extra cautiously approximately simply who can be listening in while we talk to Alexa or Siri.
