Why do we fall for April Fool\u2019s jokes?<\/h5>\n

For humans, relationships are rewarding and help to fulfill a basic social need to belong. And one of the key ingredients required for a successful relationship is trust. Unsurprisingly, research indicates that we are more likely to trust someone in our close social network.<\/span>(1)<\/span> \u00a0In fact, a 2017 study of twins suggests that<\/span> while our approach to trust may be influenced by our genes, distrust is linked to nurture, not nature.<\/span>(2)<\/span> In our last <\/span>Everyday Science with Dimensions post<\/span><\/a>, we zoomed in on the science behind the \u201clove hormone\u201d oxytocin. Not only does it bring out our warm and cuddly side, it is also responsible for a substantial increase in trust levels:<\/span>(3)<\/span> although, the good news is, it doesn\u2019t seem to make us more gullible<\/span>.<\/span>(<\/span>4)<\/span> So it seems we instinctively want to believe information from those in our trusted circles.<\/span><\/p>\n

When trust turns bad…<\/h5>\n

Not all of us are predisposed to accept what we are told at face value though – even when it\u2019s a loved one whispering it in our ear. And that can be helpful; along with objectivity, creativity and curiosity, a questioning mind is a valuable characteristic for many career paths, including research.<\/span><\/p>\n

But, for some of us, that desire to question can tip over into a fear of being duped or exploited, also known as sugrophobia. Some researchers argue that this kind of paranoia is the inevitable cost of the suspicious mind we have needed to survive as a species.(5) For some groups, it can lead to a belief that things many of us accept as fact, are, in reality, hoaxes. This has led to the emergence of flat earth campaigners, climate change deniers and groups that claim man never landed on the moon.(6) Some researchers suggest that belief in these, and other conspiracy theories may be driven by a desire to be unique and stand out from the crowd.(7)<\/span><\/p>\n

In an ironic twist of fate, at least one hoax has gone on to become a genuine research topic. Back in 2014, several outlets repeated a story from a satirical website that <\/span>the American Psychiatric Association had designated \u201cselfitis\u201d (the compulsive desire to take photos of yourself to post on social media) a new psychiatric condition. While it was meant as a joke, researchers saw the possibilities and the 2018 article <\/span>An Exploratory Study of \u201cSelfitis\u201d and the Development of the Selfitis Behavior Scale<\/span><\/a> now has an Altmetric score of 1,609.(8)<\/span><\/p>\n

The science of laughter<\/h5>\n

One of the biggest reasons we carry out hoaxes is to provoke laughter. And studies have shown that a good chuckle or giggle can have beneficial effects in situations as diverse as pain management,(9) palliative care,(10) and, crucially, working in a research lab!(11) And it can help with conditions such as stress and depression,(12) emotionally-induced over-eating,(13) and Parkinson\u2019s Disease.(14) \u00a0It can even encourage us to exercise more as we grow older.(15) <\/span><\/p>\n

Here are a few facts we gleaned from the free version of Dimensions by running a topical search for laughter (NOTE: all data for this article were extracted from Dimensions on 03.22.19).<\/span><\/p>\n

Researchers<\/strong><\/p>\n

The auto-generated analytical views tab reveals that the most published researcher on the topic is <\/span>psychologist <\/span>Willibald<\/span> Friedrich Ruch of the University of Zurich in Switzerland. 36 of his 225 publications listed in Dimensions focus on laughter. Papers include <\/span>A lifetime of fear of being laughed at<\/span><\/a> and <\/span>Neural correlates of laughter and humor<\/span><\/a>, which has been cited 199 times to date.<\/span><\/p>\n

In Dimensions, publications are linked to other content types to provide a full view of the research landscape and easy exploration of the connections between relevant grants, clinical trials, patents and policy documents. A look at \u00a0<\/span>Professor Ruch\u2019s profile page shows he has also been awarded three grants for research into the topic, including nearly 200,000 euros from the Swiss National Science Foundation for<\/span> The joyful face may hide an evil mind: Individual differences in fearing laughter<\/span><\/i><\/a> – an investigation into the social and emotional context of laughter styles.<\/span><\/p>\n

Interestingly, if we look at the locations of the 20 most published authors on the topic, the UK and Belgium feature prominently and only three are based outside Europe (in the US).<\/span><\/p>\n

Publications<\/b><\/p>\n

The Dimensions publications linked to laughter stretch right back to 1645, when \u201c<\/span>Teares, and Laughter: The Complete Poetry of Robert Herrick, Vol. 1<\/span><\/a>\u201d was published. Since then, there have been 5,563 publications – sort these by citations and we can see that Stanley Milgram\u2019s 1963 <\/span>Journal of Abnormal Psychology<\/span><\/i> article, \u201c<\/span>Behavioral Study of Obedience<\/span><\/a>\u201d, has received the highest number of citations to date (1,900). It studied the use of electric shocks as punishment and found that one of the outcomes (along with sweating, trembling, and stuttering) was to make the participant laugh.<\/span><\/p>\n

In contrast, the article which received most online attention (as measured by Altmetrics) was the 2017 <\/span>Current Biology<\/span><\/i> publication \u201c<\/span>Positive emotional contagion in a New Zealand parrot<\/span><\/a>\u201d by Schwing \u00a0et al, with an Altmetric score of 916.<\/span><\/p>\n

Publications by year<\/b><\/p>\n

Publications related to laughter have been rising steadily in number over the past eight years \u2013 increasing from 227 in 2010 to 345 in 2018.<\/span><\/p>\n

Grants by year<\/b><\/p>\n

\"\"Figure 5: The number of laughter-related grants by year (2010-2019) in Dimensions.<\/span><\/i><\/p>\n

While publications may have peaked in 2018, as we can see in figure 5, active grant funding hit its highest point in 2015 \u2013 possibly an indication that we can expect the upward trend in laughter-related publications to continue in the short term. However, with the number of starting grants falling from a peak of 24 in 2014 to five in 2018, longer term, we are likely to see a drop in publication numbers. <\/span><\/p>\n

The scope of those grants has varied enormously, ranging from the relationship of laughter to the Zen Buddhist religion and the experiences of care workers participating in laughter therapy, to the effects of immigrants and ethnicity on American humor. One of the biggest sums awarded was 2.8 million euros by the European Commission. It was given to a group of universities to help computers and machines that interact with humans learn to deal with laughter.<\/span><\/p>\n

The top five funders to date are: <\/span><\/p>\n
