The Uncertain Science of Certainty | 16th July 2025

How are scientific opinions formed? How do we converge on the truth? And once we get there, how should we try to convince others?

Microscope, books, magnifying glass: The search for proof
Proof?

On Wednesday 16th July, PubSci is delighted to welcome Professor Adam Kucharski – epidemiologist, statistician, and bestselling author of The Rules of Contagion – to talk about the crucial ideas behind his new book, Proof: The Uncertain Science of Certainty. Proof explores methods we can use to get closer to what’s really happening, and what happens when these methods fail.

With very few tickets remaining, book your place now, or read on to learn more.

Throughout history, scientific progress has relied on establishing fact from fiction. For millennia, the reasoning went: achieve logical perfection and be rewarded with ultimate, universal truth.
But demonstrating that a new medical treatment works, persuading a jury of someone’s guilt, or deciding whether to trust a self-driving car requires us to weigh up noisy, uncertain evidence.

So, is there more to proof than axioms, theories and scientific laws? Now, more than ever, we need to understand what “Gold Standard Science” really means – and what it doesn’t. Come to PubSci on Wednesday 16th July to explore the art and science of certainty with Adam Kucharski, and discover what links wine and university exams, royalty and Guinness, cricket and robot racing.

Ranging across science, politics, philosophy and economics to explore how truth emerges and why it sometimes falters, Proof is described by New Scientist as “a life raft in a sea of fake news and misinformation.” Don’t miss this unique opportunity to hear bestselling author and award-winning science communicator, Prof Adam Kucharski at PubSci.

Copies of Proof will be on sale at the event.

Sold Out : “Jinx!” – The Science of Freaky Coincidences with Prof. Chris French | 17th July

Why do we say “Jinx!” when two people say the same thing at the same time? Are coincidences as unlikely as we think? And why do some coincidences feel so spooky

On Wednesday 17th July PubSci is delighted to welcome back Chris French of the Anomalistic Psychology Unit at Goldsmiths, University of London, for a talk that is now fully booked out.

meaning-of-coincidences-dice-on

We’ve all had that uncanny feeling when things happen that seem too unlikely, too meaningful, too important to be attributed simply to random chance. Numerous well documented coincidences seem so unlikely that something more than blind probability appears to be at work. Paranormal explanations are often invoked for apparently precognitive dreams. So what’s really going on?

Conspiracy theorists and charlatans can play on our ignorance of causality, probability, and even what randomness really looks like, in order to make us think certain events have meaningful, perhaps sinister, connections. Some people make a career out of it. Even innocent coincidences can feel special to us. But why is this? And is it reasonable for sceptics to explain away such things as nothing more than “mere coincidences”?

Chris French is an expert in all things weird and freaky – how we experience them, why we believe in them and what’s really going on when we experience the uncanny. He’s already delighted PubSci with two talks in previous years, and this month he turns his attention to coincidences. At July’s PubSci, the author of The Science of Weird Shit explores the science and psychology of those freaky moments when things seem too unlikely to be “Just a coincidence”.

Book CoverI hope you reserved your place early, because the event is fully booked and there’s a long waiting list. For those lucky enough to be attending, Chris will have copies of his new book for sale: The Science of Weird Shit – Why Our Minds Conjure the Paranormal.

Nurture without Nature… What’s Wrong with Blank Slate View? (17th April 2024)

On Wednesday 17th April, PubSci is delighted to welcome evolutionary psychologist Dr. Alastair Davies to explore the nature-nurture debate in the light of modern understanding.

A blank slate with chalk ready to write

Are we born as blank slates, or is nurture balanced with nature?

Apologies for the lateness of this blog post. I’m in Mexico for the solar total eclipse, where connectivity has been difficult. Harder still has been proving that I’m not a robot… to AI systems which can’t accept that I’d be spending my money or logging into my accounts from a different country, even via VPN.

One of the things that makes us most human is our unique personalities, which develop from the moment we’re born – but are we born as completely blank slates upon which literally anything could be written by nurture and environment, or does nature imprint something unique on us from before we even emerge from the womb? And if it’s a mixture, how is that achieved?

That’s what April’s PubSci is all about.

Steven Pinker called it “the modern denial of human nature” yet in the long-standing debate over the influence of inheritance versus environment on human personalities, the “blank slate” theory was hugely influential for decades. So, are we born as raw canvases upon which the world uniquely traces its mark, or does nature impart innate qualities from the get-go?

Evolutionary psychologist Dr. Alastair Davies believes it’s time to re-assess this popular theory and consider where it leads us and what risks might emerge if we get it wrong.

PubSci is delighted to welcome Alastair to talk us through the background of, and potential problems with the blank slate theory, and explore how we might better understand how we – and those around us – came to be who we are.

Book now for an evening of profound insights. Places are limited and we’re already 60% full.

Secrets of Sleep | 21st Feb | Dr Anna Joyce

To sleep, perchance to dream… But what is going on when we do (or don’t ) sleep?

Two sleeping figures in a cornfield

Midday Sleep by J.F. Millet

On Wednesday 21st Feb 2024 PubSci is delighted to welcome Dr Anna Joyce of Regents University to speak about the neuroscience and psychology of sleep: What sleep is, why we need it, what happens when it goes wrong, and how we try to fix it.

We’re frequently told we should be sleeping 8 hours every night – meaning we would spend 1/3 of our lives contentedly in the Land of Nod – but for many people this simply isn’t the case.

Fortunately for those who feel they don’t get enough, Anna is Assistant Professor in Psychology at Regents University, specialising in developmental psychology and sleep (see biography further down this page). If anybody knows how to get better sleep, it is Dr Anna Joyce.

Join PubSci and Anna Joyce for Secrets of Sleep on 21st February. Tickets on Eventbrite are moving very fast – book today to avoid disappointment. See below for more details.
