Coronavirus lockdown, South Africa: bioethics and miscellany

Today is day 10 of South Africa’s coronavirus lockdown, which has been implemented with a resolve rarely seen in our country, with the military deployed to assist the police in keeping people in their homes. Unfortunately, neither they – nor the police – are (in general) accustomed to much besides being authoritarian. They certainly don’t have a history of “shower[ing] our people with guidance [and] leadership”, as President Ramaphosa asked of them when they were sent into the streets.

COVID-19, South Africa, and humility regarding scientific reasoning

Eusebius McKaiser (host of a show on Radio 702) and I were meant to be part of a public discussion at WiSER (based at Wits University) on COVID-19 and its social implications later this week. The conversation was in the end postponed – not because of health risks (although that is now an utterly sensible reason for postponing) – but because some people thought that a philosophical conversation was inappropriate, and that WiSER should include epidemiologists, virologists and the like on any panel related to this coronavirus.

A (partial) autopsy of pseudoscience: Natasha Bolognesi and WAVEEX

Earlier this month, Prof. George Claassen of CENSCOM (Stellenbosch University) published a piece on GroundUp, detailing how science journalist Natasha Bolognesi became the subject of disciplinary action after refusing to copy edit a study on the cellphone-attachment WAVEEX, described by the manufacturers as

a composite chip of seven superposed layers, outside of plastic, inside five layers with silver ink printed circuits, which, if they are exposed to the electromagnetic waves, weaken the passing harmful radiation and balance it with the magnetic field of your body.

I won’t spend time focusing on how it’s well-established that low-frequency EMF radiation doesn’t pose a risk to humans, nor on the journalistic ethics of Bolognesi’s choice to refuse to copy edit the piece in question.

Noakes and vaccination: if it quacks like a duck…

herd immunity

On November 29, Professor Tim Noakes was interviewed on the Gareth Cliff Show. Much of the interview focused on his new book, and his reasons for co-writing it (with Marika Sboros). I’ve previously described some of this book’s inaccuracies and falsehoods in respect of its mentions of me, including the assertion that I’m part of some conspiracy against him.

Today, I’d like to briefly focus on a more worrisome theme – vaccine scepticism – that Noakes has tweeted about in the past, and one that he returns to in this interview with Gareth Cliff. The relevant segment’s audio is transcribed below, and embedded at the end of the post. It takes place between 44m07s and 45m37s of the full interview.

Food marketing to children, and the responsibilities of parents

The Vitality ObeCity Index 2017 (pdf), released in October,  “analysed data from Vitality members living in six cities across South Africa” in order to present an overview of South African eating trends and health statistics. The report describes some positive trends, while highlighting that “we still have a lot to do to combat obesity”.

I contributed three opinion pieces on science communication, the food industry and marketing to children, and the importance of consumers making informed choices. Here’s the last of the three contributions. Continue reading “Food marketing to children, and the responsibilities of parents”

Lore of Nutrition – Prof. Tim Noakes and Marika Sboros

One good thing about the just-released  “Lore of Nutrition“, documenting the campaign (allegedly) orchestrated by myself and others against an A-rated Professor with thousand of citations, hundreds of articles, many books, regular international speaking gigs, and constant (fawning) media coverage is that it leaves you in no doubt as to who the victim is (spoiler alert: it’s the celebrity scientist).
