Justin Bieber’s opinion on the Big Bang – inconsequential, or not? (new study)

November 15th, 2018

“The vast majority of scientists believe that humans have evolved over time (98%; Pew Research Center, 2015). However, recent public opinion polls indicate much more variability in the views of the general public; only 65% of Americans (Pew Research Center, 2015), 61% of Canadians (Angus Reid Public Opinion Polls, 2012), and similar amounts of British and Australians share this view.”

A new study from Nipissing University, Ontario, Canada, has, for the first time, attempted to find out what effect ‘celebrity opinions’ might have on such viewpoints, So, when, for example, Justin Bieber [pictured] says something along the lines of :

“Science makes a lot of sense. Then I start thinking—wait, the ‘big bang.’ For a ‘big bang’ to create all this is more wild to think about than thinking about there being a God. Imagine putting a bunch of gold into a box, shaking up the box, and out comes a Rolex. It’s so preposterous once people start saying it.”

– what effect, if any, might it have on public acceptance of  evolutionary theory? In other words :

“Are publicized celebrity opinions about human evolution merely inconsequential forms of entertainment, or do they have the potential to influence individuals’ acceptance of evolution?”

The answer, according to the research, is :

“Taken together, the results of the present set of studies provide novel evidence that exposure to a celebrity’s opinion about evolution can indeed influence individuals’ acceptance of evolution.”

The Man Who—With a Blinding, Flapping Visor—Drove on a Highway

November 13th, 2018

John’s Story – The Science of Error” is a new documentary film about John Senders, the Ig Nobel Prize winning, pioneering student of human attention and distraction. Back Lane Studios produced the film:

The 2011 Ig Nobel Prize for Public Safety was awarded to John Senders of the University of Toronto, CANADA, for conducting a series of safety experiments in which a person drives an automobile on a major highway while a visor repeatedly flaps down over his face, blinding him.

He wrote about that research: “The Attentional Demand of Automobile Driving,” John W. Senders, et al., Highway Research Record, vol. 195, 1967, pp. 15-33.

This video [which is excerpted in the new documentary] shows Senders pioneering his work:

Evaluating Students’ Evaluations of Medical Professors: Are There Cookies?

November 9th, 2018

Prof. Dr. med. Manuel Wenk, co-author of the cookies study. The cookies were chocolate.

Some medical schools may be selecting or rejecting faculty members because those individuals do or do not offer cookies to their students. That is a possible conclusion one might draw, after reading this new study done by faculty members:

Availability of cookies during an academic course session affects evaluation of teaching,” Michael Hessler, Daniel M Pöpping, Hanna Hollstein, Hendrik Ohlenburg, Philip H Arnemann, Christina Massoth [pictured below], Laura M Seidel, Alexander Zarbock, and Manuel Wenk [pictured above], Medical Education, vol. 52, no. 10, October 2018, no. 1064-1072. The authors, at the University Hospital of Munster, Germany, report:

“Results from end-of-course student evaluations of teaching (SETs) are taken seriously by faculties and form part of a decision base for the recruitment of academic staff, the distribution of funds and changes to curricula. However, there is some doubt as to whether these evaluation instruments accurately measure the quality of course content, teaching and knowledge transfer.”

Documenting Meiji Gummy Candy Flavour-Recognition Times (new study)

November 8th, 2018

If you have ever eaten a ‘Gummy Candy’ from Meiji Co., Ltd., Tokyo, Japan, in apple, grape, orange, [European] pear, pineapple, or strawberry flavours, it may have taken you a few seconds to recognise which one you were eating. If so, you are not alone. A 2018 study published in the journal Perception sought to measure ‘Distribution of Recognition Times to Fruity Flavor of Gummy Candies in Healthy Adults’. The research team found, by experiment, that on average, healthy adults took around 7.5 seconds to be able to tell which flavour they were eating.


● The Ethics Committee of The University of Niigata Rehabilitation Graduate School approved the experiments

● The illustration shows the Meiji Gummy Sushi Candy, which did not feature in the study

● 22.7% of the participants got the flavour wrong
