The modern world is littered with statistical noise. Here’s how to find the signal
A $3.2 billion budget deficit; a 10 per cent improvement in quality of life; 760,000 jobs added this quarter.
Confusing, out-of-context, incomplete and flat-out inaccurate statistics no doubt account for a good chunk of
our era of information overload –
although you wouldn’t want to put a percentage to that.
In this video from BBC Ideas in collaboration with the Open University,
the UK writer and broadcaster Tim Harford offers three helpful tips for sifting through the noise to find the signal
when it comes to investigating statistical claims.

DON'T LET YOUR TOOLS GET IN THE WAY OF THINKING ABOUT INFORMATION
The challenge for the scientist, particularly in the era of Big Science, is to keep the instrument in its place.
The best scientific kit comes from thinking about how to solve a problem.
But once it becomes a part of the standard repertoire and acquires a lumbering momentum of its own, it might start to constrain thinking more than it assists it.
As the historians of science Albert van Helden and Thomas Hankins said in 1994: ‘Because instruments determine what can be done, they also determine to some extent what can be thought.’
You don't have to read these unless you wish to, but we might touch upon them in conversation
And whether or not they are objectively valuable, the ends that matter to us, the things that we care about most –
our relationships, our projects and goals, our shared experiences, social justice, the pursuit of knowledge,
the creation and appreciation of art, music and literature, and the future and fate of ours and other species –
do not depend to any considerable extent on our having control over a vast but largely irrelevant Universe ...
Most of what matters to us is right here on Earth.
Music has been a means of information exchange for eons.
This semester, we will include in each session an opportunity to watch a music item,
to think about what the piece might mean for our understanding of the world around us.
Music in any form can be a great leveler.
We might, for example, imagine joining an unfamiliar congregation within the walls of a cathedral to hear Bach's Mass in B Minor
("the greatest work of music of all ages and of all peoples," in the view of Hans-Georg Nigeli, writing in 1817).
Much may separate us: age, income, clothes and background.
We may never before have spoken to one another and may be wary of letting anyone catch our gaze.
But as the Mass begins, so, too, does a process of social alchemy.
The music conveys feelings that hitherto seemed inchoate and private,
and our eyes may fill with tears of relief and gratitude for the gift given us by the composer
and musicians in making audible, and hence available to us and to others,
the movements of our collective soul.
Violins, voices, flutes, double basses, oboes, bassoons and trumpets combine to create sounds that evoke the most secret, most elusive aspects of our psyches.
Moreover, the public nature of the performance helps us to realise that if others around us are responding as we are to the music, then they cannot be the indecipherable enigmas we imagined them to be.
Their emotions run along the same tracks as ours, they are stirred by the very same things and so, whatever the differences in our appearance and manner, we possess a common core,
out of which a connection can be forged and extended far beyond this one occasion.
A group of strangers who initially seemed so foreign may thus in time, through the power of choral music, acquire some of the genuine intimacy of friends,
slipping out from behind their stony facades to share, if only briefly, a beguiling vision of humankind.
Stand by me
I will have one selected for each session, but you all can add to the list and to our mutual growth in understanding by showing us items you find interesting.
This time Playing for Change.
From the Wikipedia entry ...
The project started in 2004 with the organization's self described goal to "inspire, connect, and bring peace to the world through music".
The creators of the project, Mark Johnson and Enzo Buono, traveled around the world to places such as New Orleans, Barcelona, South Africa, India, Nepal, the Middle East and Ireland.
Using a mobile recording equipment, the duo recorded local musicians performing the same song, interpreted into their own style.
Among the artists participating, or openly involved in the project, include Vusi Mahlasela, Louis Mhlanga, Clarence Bekker, Tal Ben Ari (Tula), Bono, Keb' Mo', David Broza and Grandpa Elliott.
The project's first single "Stand by Me", began with a Santa Monica street performer named Roger Ridley (now deceased).
The duo traveled the world, recording more and more musicians. All of these versions were considered for mixing a pastiche final version.
