Do you know how best to cut your carbon footprint?
I recently invited people to take an online survey about sustainable lifestyle changes and over 800 people kindly responded. The work was conducted with Prof Mike Page from the University of Hertfordshire and Edinburgh Science, and the results are now in!
Everyone were asked to estimate how many kilograms of carbon dioxide would be saved by taking a range of actions. Many of the ratings were hugely inaccurate, with people generally overestimating the effects of less impactful changes, such as unplugging appliances, but underestimating the contribution of larger lifestyle changes such as following a vegetarian diet. For example
….unplugging a mobile phone charger saves around 2kg of CO2 emissions per year; yet one third of respondents thought that it saved five times that (100kg or more).
….leaving a television on standby emits around 15kg of CO2 per year, but a third of respondents estimated that it was far more significant (125 kg or more).
….becoming a vegetarian can save over 600kg, yet half of the respondents thought that it only saved 300kg or less.
…buying a blue jumper rather than a red one has no impact at all, but, on average, people thought that it would save 37kg.
The good news is that other estimates about, for example, the impact of flying, were more accurate. Every little helps, and people should consider doing whatever they can to cut emissions. However, these results suggest that there are many widely believed myths about sustainable behaviour. There’s a real appetite to make changes, which is great, but many of us may need clearer information on how make the biggest impact.
Many thanks to everyone who was kind enough to take part.
I have teamed up with Edinburgh Science to conduct a short survey into your thoughts about climate change and sustainability. It only takes a few minutes and it would be lovely if you could take part. All you need to do is click here. Thank you!
I have been interested in magic since I was 8 years old. Early on, I became fascinated with the history of this strange performing art, and when I was 13 years old I wrote a school project entitled ‘The Art And History Of Conjuring’.
One section of this 34-page extravaganza was devoted to contemporary magicians and included the cover of a magic magazine featuring the legendary David Copperfield.
A few years ago, I was in Las Vegas with my friend and fellow magician, Massimo Polidoro. We went to see David Copperfield’s amazing show and he kindly invited us to his secret museum of magic. This stunning collection is housed is a large building on the outskirts of Vegas and contains a jaw dropping collection of apparatus, posters and books. It is the Smithsonian of magic and explores how magic shapes society, inspires technology, and creates a sense of wonder.
Due to the nature of the exhibits, David is only able to show a few people around the museum at any one time. Afterwards, David and I spoke about producing a book that provides readers with a personal tour of this magical space. Excited by the idea, we enlisted the help of brilliant magician David Britland and amazing photographer (and co-director of David Copperfield’s shows) Homer Liwag. Together, we put together a pitch document and were delighted when Simon and Schuster agreed to publish the book. Not only that, but the wonderful Priscilla Painton agreed to act as our editor.
Three years on and our vision has become a reality. This 270-page glossy book is our love letter to magic. Filled with Homer’s stunning photographs, it celebrates a group of outsiders who bring a much-needed sense of magic into the world, including the man who fooled Houdini, the woman who caught bullets in her bare hands, and the illusionist who made himself vanish. Along the way we encounter a sixteenth-century manual on sleight of hand, stunning French automata, and even some coins that are said to have magically passed through the hands of Abraham Lincoln.
Over forty years ago, 13 year-old Wiseman write a school project on magic and referenced David Copperfield. Today, I am honoured to have worked with this legendary performer and co-authored a beautiful book on the topic. To me, that feels like real magic.

I have just co-authored a new research paper suggesting that learning to perform magic tricks makes children more creative.
During the experiment, a group 10 to 11-year-old children completed a creativity test that involved coming up with multiple uses for an everyday object. They were then taught how to perform a simple trick in which they showed someone a cube with different coloured sides, asked the person to secretly choose a colour, and then magically revealed their person’s choice. Finally, they all completed the creativity test a second time. Compared to another group of children who took part in an art lesson, learning the trick significantly boosted the children’s creativity scores.
Magic tricks often involve lateral thinking and we suspect that learning to perform the illusions encouraged children to think outside of the box. There is a need to enhance creative thinking from a young age. Learning magic tricks would be a cost effective, practical, and fun way of teachers and parents boosting children’s creativity. Maybe in the future, magic will become part of the school curriculum!
The peer-reviewed work was carried out in collaboration with Amy Wiles and Professor Caroline Watt (Edinburgh University), and published in the academic journal PeerJ.

Last year I collaborated with The Good Thinking Society to set up the Good Magic Awards.
Our first award focused on performers who use magic tricks to improve the lives of others, including work with disadvantaged groups, hospital patients, and schools. The judges selected two great winners: Megan Swann (who presents a magic show that promotes environmental issues) and Breathe Magic (who support children with hemiplegia by helping them to learn tricks that improve physical and psychological wellbeing).
This year, the award will provide £2,000 to support a new and innovative project that promotes the art of magic. This might, for example, include developing a live or virtual performance, writing a magic-related book or essay, creating a podcast, devising a new form of illusion or presentation, or undertaking research into the history of magic.
Applicants need to be over 18 years old and currently residing in the UK, and nominations will close at 5pm (GMT) on 20th February 2021.
A few years ago I produced three videos containing ten magic-based science stunts. I thought that they might help educate and entertain children during lockdown, or indeed anyone with a curious disposition. Here they are…..
I am delighted to launch a new series of videos that use magic to celebrate science. Fab sleight of hand artist Will Houstoun and I produced them, supported by The Royal Society of Chemistry and chemist Dr Suzanne Fergus (University of Hertfordshire). The three videos use sleight of hand techniques to celebrate a different scientist, and do not involve any CGI or camera trickery.
We are excited about this new story telling technique and recently conducted an experiment that showed that it significantly boosted people’s engagement (details here).
I recently co-authored a paper on how a little-known parapsychology journal was years ahead of its time.
Our story starts in 2011, when psychologist Daryl Bem reported several experiments that appeared to support the existence of psychic ability. Soon after, Stuart Ritchie, Chris French and I tried to replicate the studies but obtained null results. Several other academics also criticised Bem’s statistics and procedures. This type of ‘I have evidence for psychic ability – Oh no you don’t’ back and forth has occurred many times over the years. However, this time, something odd happened.
Several researchers noted that the criticisms aimed at Bem’s work also applied to many studies from mainstream psychology. Many of the problems surrounded researchers changing their statistics and hypotheses after they had looked at their data, and so commentators urged researchers to submit a detailed description of their plans prior to running their studies. In 2013, psychologist Chris Chambers played a key role in getting the academic journal Cortex to adopt the procedure (known as a Registered Report), and many other journals quickly followed suit.
However, many academics are unaware that a little-known parapsychology journal – The European Journal of Parapsychology – implemented an early version of this concept in the 1970s. For 17 years, around half of the studies in the paper were registered in advance. If the critics were right, these papers should be less likely to contain problems with their statistics and methods, and so be more likely to report spurious positive results. To find out if this was the case, I recently teamed up with Caroline Watt and Diana Kornbrot to examine the studies. The results were as expected – around 8% of the analyses from the studies that had been registered in advance were positive, compared to around 28% from the other papers. Other academics are now conducting the same sort of analyses in psychology and medicine, and finding the same pattern.
Academics often criticise parapsychology, but this episode is a good example of how the field is sometimes ahead of the game and can help to improve mainstream psychology.
Psychology at The University of Hertfordshire is turning 50 this year. To help celebrate, we’re holding two competitions, which could see you win Amazon vouchers worth up to £100.
The first competition involves completing the statement, “Why I love psychology….” in a maximum of 10 words. In the second competition, we are inviting everyone to help shape the field over the next 50 years by completing the statement ‘In the next 50 years, I hope that psychology …’ using a maximum of 20 words.
There will be 5 winners in each category, so come over to the competition website and send us your entries!

The University of Hertfordshire have just launched a great online Festival of Ideas. There’s lots of amazing and wonderful content focusing around how the arts and sciences can help to tackle Covid-19, and thoughts about how the world will change post-virus.
I have contributed a talk about the making of a free online computer game that encourages social distancing. The game was created with Martin Jacob and can be played here. The game received lots of media coverage, made the BBC national news and went viral. We have now had over 75,000 people play it and the feedback has been amazing!
A report out today suggests that many people are struggling to sleep right now. A few years ago I wrote a book about the science of sleep called Night School, and here are ten top tips.
Avoid the blues: When your eyes are exposed to light, your brain produces less of the sleep-inducing hormone melatonin. Some research suggests that light towards the blue end of the spectrum is especially stimulating and computer screens, tablets, smartphones and LED lighting all emit a lot of blue light. Try not to use these devices in the two hours before you go to bed. If you must use them, turn down the brightness or wear amber-tinted glasses designed to block blue light.
Avoid nightcaps: Although a small amount of alcohol helps you get to sleep more quickly, it also gives you a more disturbed night, increases the chances of snoring and disrupts dreaming. Don’t drink alcohol in the hours before bed.
Remember the 90-minute rule: Every night your brain goes through several 90-minute sleep cycles. You feel good if you wake up towards the end of a cycle because then you are closest to your normal waking state. To increase the chances of this, decide when you want to wake up and then count back in 90 minutes blocks to discover the best time to fall asleep. For instance, if you want to wake up at 8am, you should aim to fall asleep around either 11pm or 12.30am.
Distract yourself: Research suggests that you will fall asleep quickly if you tire your mind. Try counting backwards from 100 in threes. Or, if you’re not good with numbers, think of a category (countries or fruit and vegetables) and then come up with an example of that category for each letter of the alphabet. A is for Albania, B is for Bulgaria, or A is for apple, B is for banana, etc.
Condition yourself: Russian psychologist Ivan Pavlov famously rang a bell each time he presented a dog with food, and eventually found that the sound of the bell alone was enough to make the dog salivate. The same concept can help you to fall asleep. Choose a soporific piece of music that you like, and fall asleep with it quietly playing. Over time, your brain will associate the music with sleep, and simply listening to it will help you nod off.
Get up!: If you’re awake for more than about 20 minutes during the night, get out of bed and do some form of non-stimulating activity, such as working on a jigsaw or a colouring book. This helps to prevent you associating your bed with sleeplessness. And if the problem arises later in the night, climb back out of bed and distract yourself again.
Relax: Lying awake makes many people feel anxious, and this anxiety disrupts their sleep even more, creating a vicious cycle. If you are struggling to sleep, remember that you are probably getting more sleep than you think (research shows that we all underestimate how much of the night we spend sleeping) and that just relaxing in bed is good for you.
Relaxing music: A few years ago I worked with composer Cameron Watt to use scientific principles to create a very relaxing piece of music. Lots of people have reported finding it helpful and it is free to listen to here:
A version of these tips originally appeared in an article that I wrote for The Guardian, and in a previous blogpost. I hope they help!
