The data that is and that data the isn’t: the pitfalls of using big data: In conversation with Diane Coyle

The Governance Podcast

On this week’s episode of the Governance Podcast, Mark Pennington, the Director at the Study of Governance and Society here at King College London, interviews Professor Diane Coyle. This episode is titled "The data that is and that data the isn't: the pitfalls of using big data", and discusses the various uses and implications of big data in society, and the many pitfalls that may arise.

The Conversation

‘Big Data’ fuels AI models like ChatGPT and the machine learning systems that are generating much debate about their promise – and peril – for decision-making. The impact of the technology will depend on the character of the data used. While the issue of data bias is well-understood (although not solved), less attention has been paid to other aspects such as data quality (is the data an accurate measure of the underlying object?), missing data (do we have only part of the picture?), and the meaning of data (how are the underlying concepts represented by the data constructed and interpreted)? As AI models are advancing fast enough to be deployed increasingly widely in society, there is a pressing need to reflect on the perspective on our social world created for them through the data on which they are trained and updated.
