Jennifer Raff -- a bioanthropologist and geneticist who researches and teaches at U Kansas and U Texas -- provides some excellent advice and context on how to read a scientific paper, from figuring out which papers and journals are worthy of your attention to understanding the paper in its wider context in the relevant field.
Raff advises skipping the abstract and going straight to the introduction, taking careful notes to understand the question the paper seeks to answer, digging into the experimental methodology, then looking at the response from other researchers in the field.
I want to help people become more scientifically literate, so I wrote this guide for how a layperson can approach reading and understanding a scientific research paper. It’s appropriate for someone who has no background whatsoever in science or medicine, and based on the assumption that he or she is doing this for the purpose of getting a basic understanding of a paper and deciding whether or not it’s a reputable study.
The type of scientific paper I’m discussing here is referred to as a primary research article. It’s a peer-reviewed report of new research on a specific question (or questions). Another useful type of publication is a review article. Review articles are also peer-reviewed, and don’t present new information, but summarize multiple primary research articles, to give a sense of the consensus, debates, and unanswered questions within a field. (I’m not going to say much more about them here, but be cautious about which review articles you read. Remember that they are only a snapshot of the research at the time they are published. A review article on, say, genome-wide association studies from 2001 is not going to be very informative in 2013. So much research has been done in the intervening years that the field has changed considerably).

The Bank of England has unveiled its new £50 notes, which had been earmarked to honour a distinguished British scientist, and which will feature Alan Turing, the WWII hero who discovered many of the foundational insights to both modern computing and cryptography, and whose work with the codebreakers of Bletchley Park are widely believed to […]
The great science purge, they’ll call it one day. Donald Trump is closing science offices throughout the federal government. ‘As of June, around 85 percent of all scientific posts in the federal government, including an official scientific advisor to the President, were left unfilled,’ write the editors of I F***ing Love Science blog in an […]
Ed Hawkins, a climate scientist, created Show Your Stripes as a way to easily visualize the past century's climate change: give it a location and it will render a series of stripes representing a century's worth of average annual temperatures (above: global average temperature); as Kottke notes: "The warming patterns for particular regions are not […]
When it comes to passwords, there’s no such thing as paranoia. You want them secure and complex, and you definitely don’t want to repeat them on all your accounts. The trouble is, the internet seems to keep growing. And so do those accounts. Just one lockout from an important email or banking site is enough […]
With the rising temperatures on tap this summer, the climate is going to be a frequent topic of conversation, and those conversations won’t be happy ones. Luckily, there’s a way to do a little climate change of your own – in a safe and sustainable way. When it comes to personal air conditioners, EvaPolar is […]
Whether you’re using them for next-level selfies or steady tracking shots, gimbals are a must for anyone who wants to maximize the potential of these powerful smartphone cameras we’re all carrying around. But those smartphones are also supposed to be portable, and let’s face it: Gimbals tend to offset that advantage. Weighing in at just […]
