What is confirmation bias and how does it affect our judgement? Feb 06, 2025

Show notes

Have you ever found yourself in a debate with someone and realised as it goes on, that the person you’re talking to simply isn’t going to change their mind. That might be the case even if they’re expressing a controversial point of view, or saying something that goes against scientific evidence.

It’s often because they’re so convinced their perspective is right that they can’t see any nuances in the discussion. Even when you present a solid argument that challenges their views, they only focus on what supports their position and twist it into their defense. The chances are they’re experiencing something known as confirmation bias.

What’s that? How can you avoid falling into that trap? In under 3 minutes, we answer your questions!

Why are some people always late? Feb 04, 2025

Show notes

We’ve all been late at some point, but for some, tardiness is a chronic habit. You probably know someone who’s always running behind, or maybe you’re the one struggling to make it on time.

While it can be frustrating, research shows that chronic lateness isn’t just a matter of poor time management or lack of discipline. For some, it might even be linked to underlying psychological and neurological factors.

What causes chronic lateness? Why don’t they just look at the clock? What’s going on in the brain of a chronic latecomer? In under 3 minutes, we answer your questions!

What are the dirtiest objects in your home? Feb 03, 2025

Show notes

You might assume that your toilet bowl is the dirtiest place in your flat or house, but in fact that’s pretty far from the truth.

Our homes are actually filled with items that are perfect hosts for germs and bacteria, and sometimes it’s the objects you least suspect. For example those in your kitchen or bathroom in particular. According to BBC Food, the domestic kitchen is to blame for a fair share of the 2.4 million cases of food poisoning that occur in the UK each year.

What’s the dirtiest item in the kitchen then? What other items should I be cleaning more often? In under 3 minutes, we answer your questions!

Why are some deadly diseases re-emerging? Feb 03, 2025

Show notes

If you're not up to date with your vaccinations, it might just be time to schedule an appointment with your doctor! When it comes to the diseases we’re going to be talking about today, you could be forgiven for thinking they were a thing of the past, consigned to history.

But believe it or not, some of them are making a comeback in the 21st century. Their resurgence can be partly explained by a false sense of security; basically we thought they were eradicated for good and let our guard down. As a result, vaccination rates fell, and preventive measures were relaxed.

What kind of diseases are we talking about? Did those diseases never really disappear then? In under 3 minutes, we answer your questions!

What is friluftsliv, the perfect Norwegian lifestyle trend for winter? Feb 02, 2025

Show notes

Last weekend brought snowfall across much of the United Kingdom, offering a clear sign that winter is here. Now with temperatures this low, the instinct for many of us may be to cuddle up in bed under a blanket. But the subject of today’s episode is all about getting outdoors whatever the weather.

Friluftsliv is a Norwegian term that more or less translates as “open-air living”. You could call it the outdoor equivalent of Denmark’s hygge, which is all about finding comfort indoors. Indeed, Norway has strong outdoor traditions all year round, even when days are short during the winter. Friluftsliv is so ingrained in Norwegian culture that universities offer bachelor’s degree courses in it, and it’s protected by law through the Outdoors Recreation Act.

Where does it come from? What about us city dwellers? How can we embrace friluftsliv in our local area? In under 3 minutes, we answer your questions!

How can you keep your cortisol levels under control? Feb 01, 2025

Show notes

We talk about hormones a lot on Do You Really Know, so if you’ve tuned in before, you may well already be aware that cortisol is known as the stress hormone, and it’s what helps us wake up first thing in the morning.

That’s because it’s released in large amounts between 7 and 8 a.m. and then gradually decreases over the course of the day, hitting its lowest point around 11 p.m, just in time for us to go to bed. The main purposes of cortisol are to keep us alert, fuel movement, and tap into our energy reserves.

Why would we need to keep its levels under control? What can we do to avoid producing too much? Are there any dietary changes that could help lower cortisol levels? In under 3 minutes, we answer your questions!

Where does the myth of the Loch Ness Monster come from? Jan 31, 2025

Show notes

Affectionately known as Nessie, the mythical Loch Ness Monster has been a source of fascination and terror for many centuries. Many sightings have been reported over the years, but no conclusive evidence of its existence has ever been unearthed.

Still, there are many believers out there. In late August 2023, the largest Nessie hunt in 50 years took place, organised by the local Loch Ness Exploration research group and bringing together nearly 200 people from places as far afield as Australia, Japan and the USA.

Where does belief in the Loch Ness Monster come from? Why are people still searching for Nessie to this day? Is there any possibility the monster could exist? In under 3 minutes, we answer your questions!

Why is Noah syndrome so dangerous? Jan 31, 2025

Show notes

April 2024 saw a couple in the south of France handed a one-year suspended sentence, and a ban from having pets, after they were discovered keeping 159 cats and seven dogs in their 860 sq foot apartment.

According to BBC News, the “animals were discovered last year living in filth, many dehydrated, suffering from malnutrition or infected with parasites.”That shocking animal hoarding case seems to be an example of a behavioural issue known as Noah Syndrome.

Is that Noah as in Noah from Noah’s Ark? But what causes someone to become an animal hoarder? How common is animal hoarding? In under 3 minutes, we answer your questions!

Could intentional lazy parenting foster your child's independence? Jan 29, 2025

Show notes

You have to navigate an almost endless list of uncertainties when raising a child, and it’s hard to figure out the best approach to parenting. At one end of the spectrum, you’ve got so-called helicopter parents, who micromanage every aspect of their children’s lives, and at the other end parents who are so hands-off that some label them as lazy.

Maybe sometimes they are lazy. But in other cases, letting kids learn from their mistakes is an intentional choice rather than pure laziness. You might think that stepping back means kisd are more likely to get into trouble. But that’s not necessarily the case. The idea is to scale back constant parental involvement to help kids develop their own skills, problem-solving abilities, and independence. After all, if parents swoop in to solve every issue, how can children ever figure out how to manage on their own?

Couldn’t such an approach be seen as negligent? How does one become a “lazy” parent? In under 3 minutes, we answer your questions!

Why do women live longer than men? Jan 27, 2025

Show notes

In the period from 2018 to 2020, the life expectancy at birth for women in the UK was 82.9 years, while it was just 79 for men. That’s according to data from the Office of National Statistics. And that disparity is a common trend across various countries and even among certain other species of mammals, like great apes.

There certainly are, and they span both biological and behavioral factors. Dr. Perminder Sachdev is a professor of neuropsychiatry at the University of New South Wales in Australia. Talking to Time.com for an article published on the subject in 2019, he highlighted that men are more likely to take “life-threatening risks” which could lead to them dying, in a fight for example, or a car accident resulting from driving too fast.
