Post Truth Initiative Series

This Sydney Ideas series examines fake news, alternative facts, lies, bullshit, and propaganda, from a range of perspectives–from the courtroom to cancer research, from philosophy to screenplays, from Orwell to Spice–with the goal to better understand the post-truth crisis, and to advise on how facts and reason might survive in this climate.

The series is presented by the Post Truth Initiative, a Sydney Research Excellence Initiative at the University of Sydney. The initiative brings together scholars of media and communications, government and international relations, physics, philosophy, linguistics, and medicine, and is affiliated with the Sydney Social Sciences and Humanities Advanced Research Centre (SSSHARC), the Sydney Environment Institute and the Sydney Democracy Network.

Series Chair: Professor Nick Enfield, Professor of Linguistics.

Monday 20 November - Truth, Evidence, and Reason: who can we believe?

This panel discussion will dissect the current state of public discourse around truth, evidence, and reason, and associated questions including trust, faith, and identity.

Our international panellists are at the forefront of current debate on rational discourse and the post-truth crisis. In this Sydney Ideas event, hosted by the Post-Truth Initiative at the University of Sydney, panellists will discuss their answers to the question “who can we believe?”

Each, in their own ways, will show how truth is intertwined with complex questions ranging from knowledge to authority to reality.

Monday 17 July - Scientific fraud and truth

The checks and balances of peer review have traditionally been seen as the best way to ensure sound scientific and medical research. But how does the community deal with fraud when it does arise?

Are the small numbers of incidences of fraud just an aberration, or are there cultural issues that need to be addressed?

Is the problem of fraud an inevitable consequence of the increasing pressure to publish, and the resultant exponential increase in volume of scientific output today?

Tuesday 29 August – Wrongful conviction and truth

When does evidence obscure the truth? Join us for a forum on the avoidable causes of wrongful conviction.

Wrongful convictions can and do happen – it's a sad fact of the Australian legal system. This panel will look at how evidence in legal proceedings can inadvertently support false conclusions if handled by non-experts (as is usually the case). Panel members are associate lecturer in psychology Celine van Golde, barrister and senior lecturer in law Miiko Kumar, both of the ‘Not Guilty’ project at the University of Sydney, and professional linguist Helen Fraser, of Forensic Phonetics Australia. They will present real-life cases in which errors, by eyewitnesses, police, prosecutors, and other experts led to people spent years in jail following unfair trials. With reference to their ongoing research on human perception and memory they then ask: what can we do to prevent future miscarriages of justice?


  • Dr Celine Van Golde, Forensic Psychology Lab, School of Psychology, Faculty of Science
  • Dr Helen Fraser, specialist in cognitive phonetics
  • Miiko Kumar, Barrister and a Senior Lecturer in the University of Sydney Law School

Thursday 14 September - Politics and Truth

There are many signs we’ve entered a ‘post-truth’ era defined by the burial of ‘objective facts’ thanks to a public avalanche of ‘appeals to emotion and personal belief’ (OED). Critics of this ‘post-truth’ trend like to stress the political dangers of growing government secrecy, the lies of politicians, corporate bullshit, media silence and populists’ talk of ‘fake news’. They call for a recovery of ‘truth’ in public life.

But how credible is the appeal by journalists and others to recapture ‘truth’ in our public lives? What exactly is truth? Why is it important? Or is it not as important as we imagine? Does truth-telling have its limits? Might ‘truth’ be fading from our lives, and might bidding ‘farewell to truth’ be a good thing? Two white, male still-very-much-alive professors explain their agreements, and their disagreements.
