The Authentic History of 'Junk Science'
We tested and verified its accuracy
If you have spent any significant amount of time reading content online, or if you’ve spent a small amount of time reading content online, or if you’ve ever spoken to someone who has done either, chances are very good that you’ve come across the compound noun junk science. The word is often encountered in discussions of scientific matters where not all parties involved agree with each other, and one party wishes to cast aspersions at the views, techniques, or motivations of another.
The junk that is modifying science here has been in English since the 14th century, initially meaning “pieces of old cable or cordage used especially to make gaskets, mats, swabs, or oakum.” The sense of junk meaning “any of various ships of Chinese waters with bluff lines, a high poop and overhanging stem, little or no keel, high pole masts, and a deep rudder” is etymologically unrelated to the “worthless” meaning of the word (which is from the Middle English jonke), as it comes from the Portuguese word junco, from the Javanese joṅ (“ship”).
Junk took on a number of other senses in the following centuries, most of which are applied to things of poor or worn-out quality. The sense which is perhaps most common today, meaning “trash,” is a relative newcomer, dating from the mid-19th century. Junk has also been very successful in functioning as an attributive noun, in which it performs the role of an adjective, modifying a noun which follows it. Among the earliest such uses is junk shop, which has been used since at least 1800.

Junk science became far more common in the following decade, and now seems well on its way to entering the pantheon of English junk compounds. The word is frequently found in contentious discussions on scientific matters of a political mien, and some find that it is used as a somewhat arbitrary label in an attempt to discredit disagreeable (although not inaccurate) results. We cannot give you information which would be useful for those times you find yourself arguing with someone about the validity (or lack thereof) some scientific thing, so we’ll content ourselves with giving grist for your lexical mill.
