Idiot paper of the day: “Math Anxiety and Exposure to Statistics in Messages About Genetically Modified Foods”

February 28, 2014

Roxanne L. Parrott is the Distinguished Professor of Communication Arts and Sciences at Penn State. Reading about this paper is not going to get me to read the whole paper anytime soon. The study the paper is based on – to my mind – is to the discredit of both PennState and the state of being “Distinguished”.

I am not sure what it is but it is not Science.

Kami J. Silk, Roxanne L. Parrott. Math Anxiety and Exposure to Statistics in Messages About Genetically Modified Foods: Effects of Numeracy, Math Self-Efficacy, and Form of PresentationJournal of Health Communication, 2014; 1 DOI: 10.1080/10810730.2013.837549

From the Abstract:

… To advance theoretical and applied understanding regarding health message processing, the authors consider the role of math anxiety, including the effects of math self-efficacy, numeracy, and form of presenting statistics on math anxiety, and the potential effects for comprehension, yielding, and behavioral intentions. The authors also examine math anxiety in a health risk context through an evaluation of the effects of exposure to a message about genetically modified foods on levels of math anxiety. Participants (N = 323) were randomly assigned to read a message that varied the presentation of statistical evidence about potential risks associated with genetically modified foods. Findings reveal that exposure increased levels of math anxiety, with increases in math anxiety limiting yielding. Moreover, math anxiety impaired comprehension but was mediated by perceivers’ math confidence and skills. Last, math anxiety facilitated behavioral intentions. Participants who received a text-based message with percentages were more likely to yield than participants who received either a bar graph with percentages or a combined form. … 

PennState has put out a Press Release:

The researchers, who reported their findings in the online issue of the Journal of Health Communication, recruited 323 university students for the study. The participants were randomly assigned a message that was altered to contain one of three different ways of presenting the statistics: a text with percentages, bar graph and both text and graphs. The statistics were related to three different messages on genetically modified foods, including the results of an animal study, a Brazil nut study and a food recall announcement.

Wow! The effort involved in getting all of 323 students to participate boggles. And taking Math Anxiety as a critical behavioural factor stretches the bounds of rational thought. Could they find nothing better to do? This study is at the edges of academic misconduct.

“This is the first study that we know of to take math anxiety to a health and risk setting,” said Parrott.

It ought also to be the last such idiot study – but I have no great hopes.
