A S.E.T.I. for psychology

The recent debate about the issue of reproducibility in psychology lead me to question whether 21th century scientific psychology should still regard the “conventional” experimental approach as the prime method of inquiry.

Even most controlled lab experiments produce results that are difficult to generalize to real-life, because of the artificiality of the setting. On the other hand, field and natural experiments are higher in ecological validity (since they are carried out in real-world situations) but are hard to control and replicate. Not to mention that most psychology research is consistently done primarily on undergraduate students.

I suggest that the digital revolution and the emergence of “citizen science” could offer a totally new research approach to psychology.



Every second, social media, sensors and mobile tools generate massive amounts of data concerning people’s behavior and activities. According to a recent forecast by networking company Cisco concerning global mobile data traffic growth trends, global mobile data traffic reached 3.7 exabytes per month at the end of 2015, up from 2.1 exabytes per month at the end of 2014. Mobile data traffic has grown 4,000-fold over the past 10 years and almost 400-million-fold over the past 15 years. Mobile networks carried fewer than 10 gigabytes per month in 2000, and less than 1 petabyte per month in 2005. (One exabyte is equivalent to one billion gigabytes, and one thousand petabytes.)

The analysis of these large-scale “digital footprints” may open new avenues for discovery to psychologists, revealing patterns that would be otherwise impossible to detect through conventional experimental methods. A cloud-based open data portal could be designed to gather data streams made available from volunteering citizens, following protocols and guidelines developed by scientists – think about it as a sort of “S.E.T.I.” project for psychology. Autorized researchers may access these shared datasets to make collective analysis and interpretations.

I argue that the introduction of collective digital experiments may offer psychology novel opportunities to advance its research, and eventually achieve the rigour of natural sciences.
