Open Access Week 2014 (Building Blogs of Science, October 25, 2013)
Fabiana Kubke makes an argument in support of Open Science, explaining why and how knowledge belongs to the public. Sharing knowledge is the duty of researchers and should be prioritized over career advancement and publication.
Science Gone Bad (Building Blogs of Science, October 5, 2013)
Fabiana Kubke mediates on the aftermath of a sting by Science Magazine that revealed untruthful peer review in Open Access.

After attending a CEGA Blog Forum in December of 2012, UC Berkeley economics professor Edward Miguel writes how distinctions between disciplines have limited “synergy” in working towards transparency in Social Science Research.

Monkey Business (Macartan Humphreys, March 20, 2013)
Mactaran Humphreys, a Political Science professor at Columbia University, claims that he is “sold on the idea of research registration,” after seeing firsthand how fragile the data is the research canon of political economy of development, and after trying pre-registration himself.

David Laitin contends that Political Science has been, and likely will continue to be, a observational science. He says that the model for best practices in Political Science therefore methodologically resembles epidemiology, rather than methods to improve experimental endeavors such as drug trials.
Freedom! Pre-Analysis Plans and Complex Analysis (Gabriel Lenz, March 20, 2013)
Gabriel Lenz discusses how Pre-Anylsis Plans (PAPs) prevent “data torturing,” but can have the “reverse consequence” of leading researchers to use simple analysis. Lenz contends that researchers ought to that understand PAPs allow for more complex statistical analyses, because they prevent rigorous analysis from being seen as “data torturing.”The
Need for Pre-Analysis: First Things First (Richard Sedlmayr, March 20, 2013)
Richard Sedlmayr argues that debate on Pre-Anylsis Plans (PAPs) are beside the point, because the problem with research is not that data are not being analyzed before they have been discovered, but that “exploratory analyses [are being presented] as hypothesis-driven when they aren’t.” Instead of “hundred-page PAPs,” Sedlmayr advocates for greater transparency in the documentation of research.
Transparency-Inducing Institutions and Legitimacy (Kevin Esterling, March 20, 2013)
Kevin Esterling argues that while pre-registration of research has it’s flaws–such as possibly de-insentivizing exploratory research–it is nevertheless useful as a tool for increasing transparency. Esterling believe that greater transparency is necessary in all styles of research, and while he believes this can be achieved in part by pre-registration, he believes a broader solution would the be the adoption and/or use of institutions to assist in making research more transparent.

Does (effect) size matter (Funderstorms, February 1, 2013)
Since social psychology papers typically focus on p-values and not on effect sizes, David Funder argues in this post that effect sizes are just as important. According to Funder, it is important to know the degree to which an effect occurs and psychologists should include them in their research.
Studies show only 10% of published science articles are reproducible. What is happening? (Moshe Pritsker, May 3, 2012)

Brain imaging studies report more positive findings than their numbers can support. This is fishy. (Bad Science, August 26, 2011)
Ben Goldacre discusses how validating research findings is difficult in studies of the brain, because there is not enough variation in size among research to detect publication bias. He discusses how John Ioannidis gathered a large array of research results and used a power calculation to investigate the legitimacy of the general models’ claims.
Brain imaging studies report more positive findings than their numbers can support. This is fishy. (Bad Science, August 13, 2011)
Ben Goldacre writes blog post commenting on how John Ioannidis worked backwards to conclude that brain imaging studies report about twice as many positive findings as should be possible in a random sample.
Existential angst about the bigger picture (Bad Science, May 21, 2011)
Ben Goldacre discusses how engaging, “fun,” and positive research results are more likely to be published (publication bias). He explains how a lack of pre-registration leads to many unpublished negative results, therefore deluding the “bigger picture,” of what the research is saying.
Wealth Debate: How Two Economists Stacked the Deck (The Fiscal Times, March 25, 2011)
Mark Gimein describes a study performed by two researchers, Michael I. Norton from Harvard Business School and Dan Ariely from Duke. Norton and Ariely claim that Americans prefer wealth distribution that looks like Sweden’s over the wealth distribution of the U.S. However, Gimein reports that Norton and Ariely did not relay Sweden’s accurate wealth distribution to study participants, instead asking them to compare distribution in the U.S. to income distribution in Sweden. Gimein criticizes this approach as misrepresenting economic realities.
“None of your damn business” (Bad Science, January 14, 2011)
Ben Goldacre discusses how academic journals handle retractions poorly. He shares how some editors believe that details of retractions do not need to be shared, and argues that such an attitude is not good for science.
A new and interesting form of wrong (Bad Science, November 27, 2010)
Ben Goldacre discusses the findings of the Stonewall organization, wherein their survey findings indicate average coming-out age has fallen. Goldacre points out some of the interesting statistical traps they fell into, and attests that, “Maybe we should accept that all research of this kind is only produced as a hook for a news story about a political issue, and isn’t ever supposed to be taken seriously. And in any case, my hunch is that a well-constructed study would probably confirm Stonewall’s original hypothesis.”
Moniker mumbo jumbo (Psychology in Action, November 1, 2010)
Stephanie Vezich discusses the Name-Letter Effect paper by Nelson & Simmons, which postulates that one’s initials have an affect on how successful one is. She also includes information about the response by McCullough & McWilliams, which finds that the original paper had multiple statistical errors.
(The original Name-Letter Effect paper and the response can be seen on the Corrections portion of this our website).
I love research about research (Bad Science, July 24, 2010)
Ben Goldacre comments on “spin” in academic publishing, wherein studies with negative results are not presented as negative. Instead, researchers often dig up positive results within the data and pretend that was what they were looking for originally, or they write their abstracts in such a way that distracts from the actual results. Goldacre finishes his essay by explaining how pre-registration could address this problem.
How myths are made (Bad Science, August 8, 2009)
Ben Goldacre discusses the dangers of only citing research that supports a certain claim. He looks into how misconceptions of science can spread, and become “myths” that people erroneously believe have a basis in legitimate scientific inquiry.
Pay to play? (Bad Science, February 14, 2009)
Ben Goldacre explains a study published in the BMJ that contends that research funded by the pharmaceutical industry are incredibly more likely to be published in bigger, more respectful journals than research funded by government. Goldacre argues that this is because academic journals are in fact businesses, and that they can earn more by publishing “glossy reprints” of studies for pharmo companies to use to promote their products.
You are 80% less likely to die from a meteor landing on your head if you wear a bicycle helmet all day. (Bad Science, November 15, 2008)
Ben Goldacre opines how large numbers and statistics are being used by newspapers to delude the general population.
More crap journals? (Bad Science, October 4, 2008)
Ben Goldacre ironically praises the fact that more tenuous research is being published, because he believes it will help end the misconception that, “if it’s published then it must be true.”
Pools of blood (Bad Science, May 10, 2008)
Using an example of meta-analysis that revealed the dangers of artificial drug products, Ben Goldacre discusses the importance of drug and pharmaceutical companies being transparent with their trial results and data. He argues that meta-analysis is a phenomenally useful tool that is not celebrated enough.
