Another short story involving a behavioural bias. This week, the bias is revenge.

Maybe not considered by behavioural scientists as one of the core cohort of behavioural biases, revenge certainly fits the bill. It makes people act irrationally and often behave against their own self-interest.

While I did write this week's story, it is a retelling of Roald Dahl's short story "William & Mary." I used Dahl's original story to practice my own writing, using the narrative of the original as scaffolding for my modern adaptation. If you have never read the original, I urge you to buy the book “Kiss Kiss” where this, and many other wonderfully imaginative stories, were originally published.

Thanks for listening.

Happy New Year! Have you set yourself a resolution? If so, in this episode, I share how a behaviourist psychologist would approach sticking to them and sailing past Quitters Day on January 17th.

The principles are taken from a book called Self-Help Without The Hype by Professor Robert Epstein. I was honoured to have written the foreword to the new edition last year, in which I reflect on how the world has changed since the book's original release in 1996, yet the general lessons within the book remain unchanged.

The new edition is currently on offer for the new year.

Something different for Christmas. I share a short story based on a behavioural bias.

This week, the story is called Spaghetti Sauce and is about choice overload. Choice is a paradox. We convince ourselves that we want it, and certainly rebel when it’s taken away from us, but when we get too much of it, we regularly struggle to make a choice. This story follows a young girl in Atlanta as she struggles with the choices of daily life, with dire consequences.

Spaghetti Sauce was written by me, Paul Davies, and forms part of a book I'm writing called ‘Bias: Twelve Tales of Influence’.

Would I love your feedback? Hmm? If it's positive or constructive, then I think so. If you don't like it, that's of course fine, but please keep it to yourself and don't break the little writing confidence I have. 

More interview episodes will be coming in the New Year.

In this episode of Everything’s Psychology, I sit down with Richard D. Gross, author of The Psychology of Time, to unpack how our minds construct the very thing we live inside of: time. From internal body clocks and ‘mind time’ to cultural attitudes and our awareness of mortality, we explore why time can race, crawl, or seem to stand still.

• You’ll learn why your brain is always half a second late, yet your experience still feels live and continuous.
• You’ll hear how extreme situations – from car crashes to psychedelic trips – can make seconds feel like minutes, and why the memory of an event, not the event itself, often stretches time.
• You’ll discover why age, culture, and even gender can reshape your sense of time – and what that means for how you plan and live your life.

Was the moon landing mankind’s giant leap, or was it Hollywood's greatest special effect? Was the global vaccine rollout an elaborate scheme by Bill Gates to implant microchips in all of us? And do the condensation trails you see behind aeroplanes in the sky contain chemicals to keep the population docile?

Let's be honest, a small part of us loves a good conspiracy theory. They’re exciting. They make the world feel a little less random. But why are these ideas so sticky? What makes us want to believe the unbelievable, and is there a fine line between enjoying a wild theory and falling down a rabbit hole of misinformation?

With me to discuss the psychology of conspiracy theories is Professor Jan-Willem van Prooijen, who is Head of Social Psychology at Free University Amsterdam. The second edition of his book, The Psychology of Conspiracy Theories is out in December published by Routledge.

Why do people start a podcast? I chat with host of the Growth Mindset Psychology podcast, Sam Webster Harris, about his motivations for launching a podcast and why, after 500+ episodes, he's still doing it. We chat about the psychology of motivation, self-determination, signalling theory, and whether there's a hierarchy of influencers.

Valued this year at $8 billion, OnlyFans is the video hosting site generating significant media interest, with celebrities using it to support their other work.

I chat with Dr Anna Kelberg about why people put themselves on cams, and whether it's just for the money. Also, is paying for a subscription to an OnlyFans provider considered cheating on your partner? And, is OnlyFans something which young people view as empowering or exploitation?
