Interview with Sandra Matz: "Big Data, Privacy, and Psychological Targeting"
Dr. Sandra Matz is an Assistant Professor of Management at Columbia Business School.
Dr. Matz’s research uses Big Data methods to explore the relationship between psychological variables and people’s digital footprints.
Everything that we know about [ourselves] as people is expressed in behavior to some extent, so it’s very unlikely that there is something we really absolutely cannot predict.”
Who are you, where do you work, and what is the primary focus of your research?
Is it possible to retain privacy while using popular digital services?
Could you describe your work on personality-based psychological targeting?
What are the effects of buying things in line with one’s personality traits?
Is it a problem that “revealed preferences” sometimes clash with people’s long-term interests?

Is there anything dehumanizing about a data-driven view of the human experience?
If you don’t, does that threaten the prospect of effective regulation?
Would a shift from advertising to subscription-based services help?
Beyond personality, what other types of inferences can we make from digital footprints?
Are these techniques methods different in kind or only in degree from earlier advertising methods?

Are our online environments less like echo chambers than our physical ones?
Will we reach a limit to what predictions we’re able to explain?
Do you have a way of distinguishing ethical from unethical persuasion?
