Under what circumstances do authority figures inhibit the development of knowledge?
Most researchers like to proudly evoke the titans of their field. Biologists are quick to mention Darwin, mathematicians Gauss and historians Thucydides. And even when limitations to their work are contemplated it’s done gently, with the utmost respect. You might think that The Republic’s view of the ideal society leans dangerously towards the totalitarian, or be hard at work on “extensions” to general theory of relativity, but the thought that Plato or Einstein had anything even remotely resembling a negative influence on philosophy or physics would never enter your head.
But what about psychology? In particular, what about the figure of Sigmund Freud, doubtless the most famous psychologist the world has known and clearly one of the founding fathers of the entire discipline.
In this clip, UC Berkeley sleep scientist Prof. Matthew Walker ruminates on how the enormous influence of Freud had a decidedly negative impact on the science of sleep and dreams – an influence that, he claims, we’re still living with.

Prof. Walker’s arguments are, it should be stressed, decidedly TOK-related. His concern doesn’t just focus on Freud as an authority figure and our unwillingness to question established opinion, it’s strongly related to his belief in the nature of appropriate evidence for a scientific theory – more specifically on how the inherently unverifiable nature of Freudian thinking is antithetical to our modern scientific principles.
