<Insert call to action here>

20th February 2023

This week’s newsletter starts off (relatively) lightly, with an article from Katrina about p-hacking. Katrina’s been writing some great articles for us recently, and it was a pleasure to have her on our podcast a couple of weeks ago. We’re hoping to have her join us again to talk about her new article this week, and if you’re both a listener and a reader you can get a sneak preview of what she’ll be talking about.

From trying to teach you a little about p-hacking, we go straight to begging you for help. Dan Ryan has done a good job of wading through submissions for the in progress Therapeutic Products Bill, sorting the bad from the good, and summarising the arguments he’s seen from conspiracy theorists and the like (who Voices for Freedom and others have rallied to make submissions) for why the government should keep their hands off Natural Health Products.

Obviously here at the NZ Skeptics we’re very much in the camp that regulation is a good thing. We don’t want to take away people’s ability to make dumb choices and use alternative medicine, but we do want the government to make sure those products are safe. And, ideally, we’d like to see practitioners banned from making health claims about their products if they don’t have evidence to back them up. It seems like a no-brainer, but somehow the government thinks that it should be okay to make a health claim simply because of historical use!

I follow up Dan’s article with a little about the bill itself, give you some pointers on where to look in the bill for issues, and then really try and tighten the thumbscrews and pull on your heartstrings to get you all to make your own submissions - in the end I get so desperate I even offer you all a pint of beer for your effort!

Finally, once you’ve been guilted into helping save New Zealand from the herbal apocalypse, Bronwyn continues her look into fundamentalist Christians (or Fundies, as she calls them) with Nancy Campbell and her strange family.

P-hacking

P-hacking

P-hacking is a data analysis technique that can be used to present patterns as statistically significant when there is really no underlying effect. It is a misuse of statistics and a misrepresentation, plain and simple, and disappointingly it's usually perpetrated by scientists.

The Therapeutic Products Bill: Separating the Myths from the Facts

The Therapeutic Products Bill: Separating the Myths from the Facts

The NZ Skeptic's committee has been busy working on our submission for the new Therapeutic Products Bill introduced last year. This new bill aims to regulate therapeutic products in New Zealand, including medicines, medical devices, natural health products, and active pharmaceutical ingredients, to ensure their safety, quality, and efficacy. The Bill will replace the current Medicines Act 1981, Dietary Supplements Regulations 1985, and other minor acts like the Sunscreen Act 2022. The purpose of the Bill is to protect and improve the health of all New Zealanders by regulating therapeutic products across their lifecycle. The Bill will require therapeutic products to receive market authorisation before they can be imported, exported, or supplied in New Zealand. The Bill also regulates controlled activities related to therapeutic products, including manufacturing, supply, exporting, clinical trials, and advertising restrictions. A Therapeutic Products Regulator will be established to oversee these regulatory matters.

It's all about the NHPs

It's all about the NHPs

The proposed Therapeutic Products Bill is currently at the Select Committee stage in parliament, and the committee is looking for feedback via its submissions process. For the first time maybe since the repealed Quackery Prevention Act of 1908, this legislation will attempt to police “alternative medicine”. Almost everything about regulating Natural Health Products (abbreviated to NHPs in this legislation) is new territory. The main issue with this bill, at least from our reading of it, seems to be that the government considers evidence of historical use of an NHP treatment for a condition to be “substantiation” of any health claims about it. So, basically, if a natural health product has been used in the past for treating a medical condition, whether it actually helps or not, the government will just assume that it is effective. This, to my mind, is reckless and dangerous.
