When Sanne describes the path that led her to where she is now, it sounds like a puzzle whose pieces finally fell together neatly into her current position. Toward the end of her study she won a contest on microcredit. The prize was a trip to a microcredit project in Uganda, and Sanne saw this as an excellent opportunity to do a research project. Studying the effects of mobile phone use on personal income in Uganda led her seamlessly to her PhD where she put this study in a wider context concerning wellbeing.

Sanne: “The title of my dissertation is ‘Well to do or doing well’. I asked myself what determines our wellbeing and what role other people play in the process. In order to answer those questions, I set up various research projects, approaching the subject from different angles."

"Economists tend to measure wellbeing in financial terms, such as Gross Domestic Product (GDP). However, we shouldn’t read too much into the numbers. It is not self-evident that people with high incomes also feel well. Money is no guarantee for a happy relationship, good health or an interesting job. There is a growing interest in alternative measurements of wellbeing. One of those is happiness."

Sanne Blauw (1986)

obtained a master’s degree in Econometrics (2010, cum laude) at Erasmus School of Economics. After conducting het doctoral research at the Tinbergen Institute, she successfully defended her PhD thesis in December 2014. To share her knowledge about numbers and statistics with a wider audience, Sanne Blauw started working as a journalist for online platform De Correspondent.

“One of the biggest lessons I learned during my PhD at Erasmus School of Economics was that collecting data always involves making choices that may influence the results you find. I used to think, like most people, that numbers are facts you cannot argue with. However, this is precisely what you should do: always ask yourself where this number came from and what its limitations are.”

Science and journalism are really not that different

The final piece of Sanne’s puzzle seems to be De Correspondent, an online news platform which distinguishes itself with its philosophy about journalism. “Just like numbers, journalism always has a subjective dimension, caused by the people who choose what to write about and how to write about it. De Correspondent recognizes that. On top of that, we try to report on the stories that tend to escape the regular news. The misuse of statistics is such a topic.”

We all need a critical attitude

“My ambition is to bring about a realization that we all need a critical attitude. Last year I wrote an article on control by numbers in the public sector. For me it was shocking to see that in some cases the work of public sector professionals is reduced to quantitative categories. Not only does an oversupply of numbers not tell us how well the professionals are doing their job, it actually prevents these people from doing it properly. I hope the notion that we don’t need to express everything in numbers will gain ground."

'Always ask yourself where this number came from and what its limitations are.'

"Don’t get me wrong, I love numbers. That’s probably why it irritates me when they are misused. A classic example is an opinion poll that is presented as something that can predict the election with great precision. Well, it can’t predict and it’s not accurate. In the run up to the recent Dutch elections we saw some news programmes starting to report margins of error, which is definitely a step forward.”

Sanne sounds reasonably optimistic about the future. Anecdotal evidence suggests to her that more people are indeed developing a healthy, critical attitude towards numbers. But her job is far from done. Especially with the possibilities of Big Data, the use of large datasets coupled with powerful algorithms, it is more important than ever to understand the limitations of data. Sanne: “Weapons of Math Destruction’ a book by the mathematician Cathy O’Neil makes it abundantly clear such algorithms are a threat, especially to the most vulnerable in society.”

With the increasing reliance on Big Data in all parts of society, vigilance is key. We are lucky to have Sanne on our side in our defense against Weapons of Math Destruction.
