Here is a graphic showing the usage of the words “scientists”, “researchers”, “soldiers” in English-language books published in 1900-2008. The graphic was generated using the Google N-gram Viewer which scours all digitized books in the Google database for selected words and assesses the relative word usage frequencies.

It is depressing that soldiers are mentioned more frequently than scientists or researchers (even when the word frequencies of “scientists” and “researchers” are combined) in English-language books even though the numbers of researchers in the countries which produce most English-language books are comparable or higher than the number of soldiers.
Here are the numbers of researchers (data from the 2010 UNESCO Science report, numbers are reported for the year 2007, PDF) in selected English-language countries and the corresponding numbers of armed forces personnel (data from the World Bank, numbers reported for 2012):
United States: 1.4 million researchers vs. 1.5 million armed forces personnel
United Kingdom: 255,000 researchers vs. 169,000 armed forces personnel
Canada: 139,000 researchers vs. 66,000 armed forces personnel
I find it disturbing that our books – arguably one of our main cultural legacies – give a disproportionately greater space to discussing or describing the military than to our scientific and scholarly endeavors. But I am even more worried about the recent trends. The N-gram Viewer evaluates word usage up until 2008, and “soldiers” has been steadily increasing since the 1990s. The usage of “scientists” and “researchers” has reached a plateau and is now decreasing. I do not want to over-interpret the importance of relative word frequencies as indicators of society’s priorities, but the last two surges of “soldiers” usage occurred during the two World Wars and in 2008, “soldiers” was used as frequently as during the first years of World War II.
It is mind-boggling for us scientists that we have to struggle to get funding for research which has the potential to transform society by providing important new insights into the nature of our universe, life on this planet, our environment and health, whereas the military receives substantially higher amounts of government funding (at least in the USA) for its destructive goals. Perhaps one reason for this discrepancy is that voters hear, see and read much more about wars and soldiers than about science and research. Depictions of heroic soldiers fighting evil make it much easier for voters to go along with allocation of resources to the military. Most of my non-scientist friends can easily name books or movies about soldiers, but they would have a hard time coming up with books and movies about science and scientists. My take-home message from the N-gram Viewer results is that scientists have an obligation to reach out to the public and communicate the importance of science in an understandable manner if they want to avoid the marginalization of science.
