You may remember that we discussed the idea of intersectionality in a previous episode of Do You Really Know?. The term describes how characteristics like race, class, gender, sexual orientation and physical ability “intersect” when it comes to social discrimination.

Thankfully there’s a method to improve your efficiency and concentration which may hel...

Some theories in evolutionary psychology propose that men are better at spatial navigation than women due to evolutionary factors. In prehistoric times, men, as hunters, traversed long distances, while women stayed closer to the home.   This difference supposedly led to natural selection favouring genes in men associated with better spatial navigation skills. However, these theories have been wide...

Barbie has quite the impressive CV. She has had over 150 careers including fashion editor, surgeon and astronaut - enough to inspire any young fan. But what she has career-wise, she lacks when it comes to inclusivity. Barbie is usually blond, perfect and impossibly proportioned - there is a reason Margo Robbie is playing her in the latest Barbie film. But this is finally going to change: Barbie is...

Not long ago we talked about the Pygmalion effect in an episode of Do You Really Know? Well today’s subject is pretty much the exact opposite! The Golem effect is the idea that negative words or assumptions can influence behaviours and transform those assumptions into reality.

“I can’t wait for us to get married;” “Let’s travel the world together;” “We’re going to have two kids and buy that apartment across the street” When you’re in a romantic relationship, it can be genuinely heartwarming to hear your partner paint a vibrant picture of days ahead. But what about if it happens much earlier than you expected - say on your second or third date? Usually at that stage, you...

Each of us has our own unique experience of social bonds, influenced by our childhood, previous relationships, and personality. And there’s actually a psychological theory that helps explain how we experience our relationships: attachment theory. In psychology, attachment is the strong bond between an individual and an "attachment figure." In most cases, our first attachment figure is the parent w...

The number of free-to-use ATMs in the UK has been steadily declining, with a 6% drop from 2022 to mid-2023. This reflects a shift in consumer habits, as cash usage has decreased significantly. For example, weekly ATM withdrawals fell by nearly a third, from £2.2 billion in 2019 to £1.5 billion in 2023. The shift began years ago but accelerated during the COVID-19 pandemic. In 2021, cash accounted...

What is Wikipedia? Thanks for asking!  OK so everybody already knows what Wikipedia is, but let’s look closer at its history, how it works and the limits of this collaborative, volunteer-produced internet encyclopedia.

On Sunday the 7th of December London commuters braved the cold to strip off to their underwear for this unusual event. The No Trousers Tube Ride, as it is officially called, is an annual event that takes place on the first Sunday of January...

The idea might seem like something out of a fantasy, but “Foreign Accent Syndrome” is a genuine, albeit very rare, neurological condition! It sees a person begin to speak with an accent different to the one they had prior to having a stroke; one which makes them sound like they come from an entirely different country! Since the first case was discovered in France in 1907, there have only been abou...

As thunderclouds gather and winds intensify, the decision to shut off the power becomes a critical one, balancing safety concerns with the practicalities of daily life. The risks associated with electrical installations depend on the location of your home. For example, the consequences are more severe if your home is in a rural or mountainous area, for a number of reasons. Lightning poses a signif...

Restless sleep, a hollow feeling inside and the sting of heartbreak; most of us have been through that kind of ordeal at least once in our lives. Let’s be honest: when it comes to your career and work life, a breakup doesn’t exactly bring out the best in your productivity. And at work, you can’t always afford to be distracted. Earlier in 2024, a Filipino lawmaker proposed an unexpected solution: a...

The "cuffing season" refers to that time of year—typically from October through February—when people are more likely to pair up.

In essence, it’s a way of finding some warmth and connection to help navigate the winter chill. A study published in Perception and covered by Slate ex...

In some religions, people believe in reincarnation or an afterlife, but in medicine, life is generally considered to end when the heart stops beating.

On November 5, 2024, Donald Trump was elected the 47th President of the United States. That same evening, his opponent, Kamala (like calm) Harris, conceded at Howard University, urging supporters to “never give up the fight,” especially for women’s reproductive rights.

A Pew Research Center survey from August 2023 found that 52% of respondents were more concerned than excited about AI in daily life, compared with just 10% who felt the opposite. It’s not surprising really when you think about it; after all, things that we don’t understand tend to both fascinate and frighten in equal measure. It’s only very recently that AI has started becoming part of many people...
