“Heresy should be encouraged because that’s how breakthroughs happen.”
We often like to think we live in an age of reason. The fruits of modern science and technology are all around us: from smartphones and 3D printers to cures for some of history's most devastating diseases. We now have the highest life-expectancy our species has ever experience. Despite all this, a backlash seems to be emerging against certain aspects of science. Lately the revered process of peer review has been coming under fire – especially in the field of medical science. A recent piece in The Economist even argued that the internet means anyone can now appoint themselves a peer, thereby providing a challenge to the perceived power held by scientists.
In this forthright interview, cosmologist Carlos Frenk examines in detail one of the cornerstones of contemporary scientific process. He argues that peer review actually encourages unorthodox thinking, but warns, controversially perhaps, that science is a spectrum, and some disciplines may not be as rigorous as others.
Frenk is Director of the Institute for Computational Cosmology at Durham University, where he builds models in state-of-the-art supercomputers in an attempt to understand the evolution of the structures of our universe.
Do you think an inevitable part of the process of peer review is that it somehow prevents useful, fertile, if not correct ideas from being explored?
Let me first qualify my answer to this and to all of these questions – I speak from personal experience as a practitioner of a very particular branch of science which is astrophysics. I can probably speak for most of physics, but my experience is very much coloured by that.
