Katrina Borthwick

Katrina Borthwick is a huge science nerd and her main interests are in psychology, astronomy and science fiction. She has been a skeptic ever since she read ‘Demon Haunted World’ by Carl Sagan in the 90s and is super interested in what makes people think the way they do. She lives in Wellington with her husband Alan, her two young daughters and two annoying cats.

Tukdam

11 May 2026

Tukdam

This article is inspired by reading Nexus, a science fiction thriller by Douglas E. Richards and Joshua Calvert. I won't ruin the story, but it's a page turner for sure, and draws on a bunch of dubious pseudoscience including the origin of the pyramids, near death experience (particularly the well-known Pam Reynolds case), and something called 'tukdam'.

Don't say it don't use it - Alzheimer's treatments and the stats vs effect dilemma

The Cochrane Reports are comprehensive reviews that summarise and evaluate the results of clinical research on healthcare interventions. They are produced by an international network of researchers and healthcare professionals called the Cochrane Collaboration. These reports are widely respected for their sound scientific approach, and often include meta-analyses of multiple studies.

Has NASA found alien technology in our skies?

Has NASA found alien technology in our skies?

What a headline! MSN and the Daily Mail Online report that a former NASA-affiliated scientist, Ivo Busko, supports claims that unusual light flashes seen in 1950s sky photographs could indicate “non-human intelligence.” They report that his argument builds on earlier research by astronomer Beatriz Villarroel, who identified mysterious “transient” lights in archival images taken before satellites existed. This suggests the phenomenon is real and not a data error. Some of these lights appeared reflective or rotating, leading to speculation they could be objects in orbit. Because the observations predate the 1957 launch of Sputnik, proponents argue they cannot be human-made and may point to extraterrestrial technology. Here's that headline:

Inside the Manosphere – Louis Theroux

Louis Theroux's latest documentary, Inside the Manosphere, dropped on Netflix on March 11th. In it, Theroux hangs around a few notable influencers to see what's really going on.

Philology Fictionology

In 2016, Florent Montaclair was the proud recipient of the Gold Medal in Philology, awarded to him by the International Society of Philology. This award is equated with the Fields Medal or a Nobel prize… or so he would have us think.

Uncanny Valley

Uncanny Valley

Do you ever get the creeps from a robot that's just a bit too lifelike, or feel a shiver run down your spine when a CGI character seems like it's almost - but not quite - human? This weird feeling is called the uncanny valley effect.

Menopause Supplements

20 January 2026

Menopause Supplements

As a woman of a 'certain age', I am finding that as I scroll through social media I am being ambushed by sponsored posts promising to “banish hot flashes for good” and “restore youthful balance with one natural pill a day” or, more recently, “balance my cortisol”. It seems I'm not alone.

Can AI replace your lawyer?

Can AI replace your lawyer?

I was interested to read a recent news report about James Kelly (not his real name) and his legal adventures using generative artificial intelligence (AI).

Give me 3D printed dinners (please)

8 December 2025

Give me 3D printed dinners (please)

Imagine coming home from a long day at work and you forgot the groceries and haven't got anything to cook. Just as you're about to panic-order some Uber Eats you remember you can just boot up your 3D printer, whack in some basic ingredients, and a little while later out pops a perfect burger! I know this sounds like something from Star Trek, where Captain Picard could dial up anything from lobster ravioli right through to a “tea, Earl Grey, hot”. But thanks to advances in food engineering, we might be closer than you think. 3D food printing is a rapidly developing technology that has attracted interest from engineers, chefs, health professionals and the occasional sci-fi nerd.

Hunt, Gather, Parent - Book Review

It's always interesting to read (or in my case stream) a book that really challenges my assumptions and reality. This book sure did!

Win any argument… ridiculously

Win any argument… ridiculously

If you are sick of being the skeptical 'voice of reason' in arguments, perhaps as an alternative to engaging in a proper discussion you could try using some logical fallacies, humor, or psychological tricks to confuse, disarm, or simply shut down your opponent.

The Problem with Family Court Social Science

The Problem with Family Court Social Science

A research paper published in February 2025 by Carrie Leonetti from the University of Auckland (UoA) School of Law looked at how judges, lawyers and psychologists use social science research in the New Zealand Family Court. This was published in the Indiana Health Law Review. In the abstract it states:

Gerson Therapy strikes again

Earlier this month the UK Coroner ruled that British health blogger Kate Shemirani, who promoted conspiracy theories, had "adversely influenced" her daughter, Paloma Shemirani, to refuse chemotherapy, causing her death from cancer on the 24th of July 2024.

The 2025 Keto Mice Update

29 September 2025

The 2025 Keto Mice Update

Some recent research has pointed to some potential health impacts for those on the keto diet long-term. I wrote about the keto diet in the newsletter in May 2023, so I was interested to see this update as we are sorely lacking long term data on the impacts of this diet on healthy people. Although the diet has been used since the 1920s as an intervention for some specific health conditions such as epilepsy, I am more interested in whether it is an unnecessary risk for those who do not have a specific medical condition.

Numeracy and Health Outcomes

1 September 2025

Numeracy and Health Outcomes

On a recent American Psychological Association podcast the hosts interviewed Dr Ellen Peters, author of Innumeracy in the Wild: Misunderstanding and Misusing Numbers. Her book discusses how numeracy affects people's health, financial security, and other life outcomes. She is also the author of some interesting papers in the same field, including this one that sets out a framework for interventions to improve the situation.

Gadget Scams

Gadget Scams

Sometimes I get weird MSN 'News' landing pages that are chocka with adverts. One of the linked pages I saw recently was this one. It lists piles of gadgets that I apparently urgently need, and which are going to sell out soon. Being curious, I had a look.

Quantum communication in telepathy

4 August 2025

Quantum communication in telepathy

There we go. There's that word we hear so often as skeptics, 'quantum'. It seems likely Ky is referring to a state called 'quantum entanglement' that results in entangled particles (and photons) having their states correlated over theoretically limitless distances, through tiny wormholes.

Neuroplasticity and nootropics

21 July 2025

Neuroplasticity and nootropics

According to Life Extension, a website selling brain-boosting supplements called nootropics, our brains can be hacked (known as “neurohacking”) through “a variety of complementary strategies, including dietary and lifestyle changes and the use of nootropic drugs and supplements, brain-training activities and games, and neurotechnologies (e.g. electrical stimulation devices) designed to increase brain fitness”. Their Australian branch will sell you 30 pills for about AU$30. The pills contain gotu kola, bacopa, and marigold extract.

How long can humans live?

How long can humans really live without changing their actual form, for example by doing something drastic like a brain transplant, cloning, or uploading themselves to the cloud?

The Golden Dome

9 June 2025

The Golden Dome

On 27 January POTUS (the President Of The United States) signed an executive order to create an “Iron Dome” of defence against ballistic, hypersonic, cruise missiles and other advanced aerial attacks. This was renamed “Golden Dome for America” on 24 February. Surprisingly, the renaming isn't about POTUS' preference for golden things. Apparently “Iron Dome” is a registered trademark, owned by an Israeli defence firm.

Is 'mansplaining' a thing?

26 May 2025

Is 'mansplaining' a thing?

I have an out-of-town meeting, and the other party is bringing a lawyer. I print a recent court decision that I think could be very relevant. I read it, this takes a while, but I come to the conclusion that nope, it's not relevant to my case. Time wasted. I'm in a rush and there is no recycling bin near me, so I put the court decision in my bag and start driving.

Sovereign Citizens: Part Three - the Courts

28 April 2025

Sovereign Citizens: Part Three - the Courts

In part one of this series I recapped the core beliefs of sovereign citizens, and where those beliefs come from, as well as some of the mischief being caused for Councils and the Police. In part two I looked at their interactions with Justices of the Peace. In this final part I explore what's been happening in our Courts. The focus is mainly on NZ Courts, but I will also delve briefly into a couple of Canadian cases, one of which is drawn upon extensively in most NZ Court rulings around sovereign citizen behaviour.

Sovereign Citizens: Part Two – Justices of the Peace

14 April 2025

Sovereign Citizens: Part Two – Justices of the Peace

In part one I recapped the core beliefs of “Sovcits” (Sovereign Citizens) and where those beliefs come from, as well as some of the havoc being caused for local Councils and the Police. I really do recommend you read that part first if you are curious about the 'why' of Sovcits.

Cyclone Alfred Nonsense

Cyclone Alfred Nonsense

When cyclone Alfred hit Brisbane, the Gold Coast and the North of New South Wales recently, I was watching the news coverage closely. My sister lives on the Gold Coast and, according to the Bureau of Meteorology, she was going to be in the zone predicted to be hit with the most damaging winds. She was pretty sure this was no big deal for her, and fortunately she was right.

Keep it real online

Keep it real online

This week I accidentally stumbled upon an excellent resource created by the Department of Internal Affairs (DIA) called Keep It Real Online. This website has content targeted at youth, as well as content for teachers in Primary and Intermediate/Secondary School.

Apple Cider Vinegar

Apple Cider Vinegar

The new Australian mini-series Apple Cider Vinegar was just released on Netflix. The series dramatises the true story of Australian Belle Gibson, who was a wellness influencer who falsely claimed to have cured her terminal brain cancer through diet and alternative medicine. She released an app, and later a recipe book, called The Whole Pantry, and pocketed $300K in donations meant for charity.

Incoming Asteroid just might hit earth

It's not a good day when a closer analysis of the path of a near-earth approaching asteroid doesn't rule out impact, but instead shows that it might actually hit earth in 2032.

Cryptids of New Zealand: Part 2

9 December 2024

Cryptids of New Zealand: Part 2

In part one of my delve into obscure local cryptids we looked at the Kabagon, which bore more than a passing resemblance to an elephant seal, the Roa Roa, which was likely a case of mistaken identity of livestock, and the Rotomahana Saurian, which may well have been a floating tree. Here are three more cryptids I found that appear to have rational explanations:

Cryptids of New Zealand: Part 1

I'm taking a break from my post conference daze to write about something completely unserious – New Zealand Cryptids. Cryptids are animals whose existence or survival is disputed or unsubstantiated, such as the Yeti or the Loch Ness Monster.

X39 Patches, brought to you by LifeWave

I went to the Go Green Expo in Wellington on the 2nd of November, along with Mark, Bronwyn and my two tiny sidekicks. Mia had a great time having her own little disco on the power company's display, and they both enjoyed all the free samples. However I had to steer them clear of the booze, and there was a surprising amount of that. That and mushrooms. I think I must have missed a memo somewhere – when did mushrooms become a thing?

All Hallows Eve

14 October 2024

All Hallows Eve

Halloween wasn't really a thing growing up in New Zealand over 40 years ago, but it seems to have taken off in the last few decades. No trick or treaters have been determined enough to find their way to the top of the hill where I live, and I've now stopped buying lollies to save our waistlines at home. If we do ever get one, we'll need to think of a really good trick - or worse, give them fruit.

Way remains murky for MDMA assisted therapy

MDMA assisted psychotherapy is looking a little rocky lately. The Journal of Psychopharmacology has recently retracted three research papers supporting the treatment over data integrity concerns, and the FDA has rejected it as a treatment for PTSD.

NZ Researcher Silenced

2 September 2024

NZ Researcher Silenced

A recent paper on the overuse of spinal imaging (usually X-rays), titled “_An investigation into the chiropractic practice and communication of routine repetitive radiographic imaging for the location of postural misalignments_” and led by New Zealand researcher Brogan Williams​ (in collaboration with others from Australia and the US), has criticised the distributor of a chiropractic product called Denneroll. Denneroll is a US company, but their products are distributed in New Zealand and the contact given for distribution here is a Hawke's Bay Chiropractor – Rosina Walker.

Olympic Level Cropping

Olympic Level Cropping

There was a bit of a fuss this week with a scene of Greek gods being said to be blasphemous, poking fun at Da Vinci's last supper. The comparison has presumably been made because people were sitting at a table, in a row (although I note that it's quite difficult to do it any other way!)

Not so 'super' conductivity

In his introduction to the Newsletter in late July Craig mentioned the materials science news around the possibility of room temperature superconductivity, with a compound called LK-99 being announced out of a research team in South Korea. At the time there was a lot of skepticism about this claim.

The Weirdness of Pain

The Weirdness of Pain

Reading some of the latest research on chronic pain management led me down a rabbit hole of further reading, and the discovery of just how damn weird and counterintuitive pain is.

Psychology myths

Psychology myths

Bronwyn suggested I do a bit of psychology myth-busting. So here goes. There are so many I could write a book, so I've picked five. You will notice I haven't included any that relate to actual mental health disorders, I will leave that to the professionals.
