Discussing science on social media

Ken Perrott Sep 03, 2015

Some relevant memes I picked up on Facebook recently. How often do discussion partners adopt this approach?: Or when pushed for their “evidence” we have to respond with: Finally, a citation from their recommended “scientific” source – but: Then – the “nuclear” or Mutually Assured Destruction  (MAD) approach  – scientists can’t be trusted anyway: … Read More

Ken Perrott Sep 01, 2015

Problems with Sitemeter The problems with SiteMeter are still bad  this month. I gave some of the background to these problems in my post Time to give up on Sitemeter.

Ken Perrott Aug 30, 2015

Looks like Australians have won another small victory in the way that their religiosity is officially assessed. In particular how census forms pose the religion question on census forms is posed.   I discussed the problems in my article Non religious in Australia and New Zealand.

Ken Perrott Aug 24, 2015

Religious instruction scrapped from curriculum – what a great headline to see in the newspaper. Unfortunately, it is just for the Australian state of Victoria. But it could well happen here, considering the opposition to religious instruction in state schools we are seeing in New Zealand. Victorian schools are scrapping special religious instruction from class time to make … Read More

Alternative reality of anti-fluoride “science”

Ken Perrott Aug 20, 2015

Paul Connett made many unsupported claims in his presentation against community water fluoridation (CWF) to Denver Water. Here I debunk a claim where he rejects most scientific studies on the cost-effectiveness of CWF. Different grades of dental fluorosis Connett asserted two things in his presentation: Previous research showing the cost effectiveness of community water fluoridation (CWF) has … Read More
