ANNOUNCEMENT: Principia Scientific Australia Launched!

Written by John O'Sullivan & Dr Judy Ryan


Principia Scientific Australia (PSI-AU) is officially launched as a bespoke service to Australians who are concerned that creeping politicization of science is unhealthy and needs to be challenged.

We are very proud of this new independent, grass-roots supported, online player in the defense of the traditional scientific method.

PSI-AU is run by Australians for Australians – an independent subsidiary of Principia Scientific International. Please check the ‘About’ drop down menu at top of the site for full details.

As regular readers/members of Principia Scientific International (PSI) will note, the ‘look’ of the new site is very much in the same style as the original. It certainly shares our greater international goal: to uphold the traditional scientific method, as extolled by Professor Karl Popper.

For over a decade PSI’s 1,600+ members, along with our co-founder and esteemed climatologist, Dr Tim Ball, have been warning of the perils of ‘The Deliberate Corruption of Climate Science.’

According to Popper, one of the most influential philosophers of science in the past millennium, “In so far as a scientific statement speaks about reality, it must be falsifiable; and in so far as it is not falsifiable, it does not speak about reality.”

Principia Scientific Australia strives to:

  • Be the leading independent voice in Australia for principled science as per the Traditional Scientific Method (TSM) and associated ideas of Popper;
  • Be an authoritative source of information for the advancement of new scientific ideas and the raising of standards in science for the benefit of the broader Australian community;
  • Publish books, periodicals, give lectures and media interviews as part of our diverse program of support for encouraging the application of the principles of TSM in the Australian community;
  • Collaborate with national scientific societies and policymakers for the advancement of science, science education and the science community

PSI-AU will continue to champion skeptical voices in the global warming debate, plus give special focus to Australian developments in Astronomy and Geology which counter the rise of post-normal science.

However, a key difference is that, unlike PSI, PSI-AU has greater freedom to engage in issues that would otherwise be deemed too politically-focused for PSI (conflicting with its legally-incorporated, non-profit status).

We are very proud to have as the site’s Editor-in-chief Dr Judy Ryan. Judy is a retired scientist living in Canberra, a well-respected, veteran activist for higher standards and greater accountability in government science.*

Funding for the new site has been generously provided by fellow Australian, Gregg Thompson, amateur astronomer and entrepreneur.

We do hope everyone will enjoy the new site. Please do feel free to send in ideas for posts to Dr Ryan at

[John O’Sullivan is the coordinator of PSI International. Dr Judy Ryan the Assistant Director and Editor of PSI Australia (PSI-AU)]

  • Judy has been holding prominent alarmist academics accountable in the media. And holding ABC and others accountable. And doing so methodically and strongly yet respectfully. A sample of Dr Ryan’s important work is below:

    Congratulations on this important initiative and milestone.
    PSI is filling a vital community service that other professional organisations are not filling – for whatever reasons.
    May PSI-AU have a successful any impactful future.
