Open science is just as important for qualitative data as it is quantitative data. Here are a collection of resources to help encourage these practices.
PsychBriefQualitative research is a valuable way to gain insight into a phenomenon, people's experiences, etc. Improving its rigour by encouraging open science practices is just as important for this research as quant. So I've collected resources & guidance to help
A few recent talks have discussed how the culture of academia is shifting towards open science. But where does that leave Early Career Researchers?
PsychBriefRecent #metascience conferences have made me reflect on culture change and how people (especially ECRs) are impacted by this. I wrote a short post exploring this: psychbrief.com/reflections-on… How do you think we change the culture? What is already being done to shift things?
Dual process theories (Kahneman & Tversky's famous Type 1 and Type 2 thinking) are extremely popular. But what is the evidence for them?
PsychBriefDual process theories e.g. Type I & Type II thinking, are very popular. So presumably they have a very strong theoretical and empirical foundation? Right? Maybe not... psychbrief.com/dual-process-t… Latest post exploring how my confidence was shaken in this ubiquitous idea
PsychBriefPsychology research may be able to provide insight during a crisis, but a lot of the research isn't high quality enough to know. Having a scale to give guidance as to how ready research is to help in a crisis is valuable
PsychBriefMathematical psychology allows presentation of ideas in ways that can be applied in novel situations, as well as theory development psyarxiv.com/ygbjp/ Thought-provoking preprint from @djnavarro.
I'm grateful I was invited to the Cambridge ReproducibiliTea session to talk about preregistration and Registered Reports. This is a summary of our chat.
PsychBriefPreregistration & Registered Reports: what are they, what are their strengths and weaknesses, and how are they used? Discussion at the Cambridge ReproducibiliTea meeting last week (summary here): psychbrief.com/summary-prereg… Thanks again for inviting me to chat about this! @bg_farrar
Cleaning out the file drawer is an idea that has been floating around on twitter, but is it feasible? What does it mean for past studies? Is there a way in which we could get a sense of how many studies are in file drawers? Also, we discuss writing...
We chat with Kevin Mitchell (Trinity College Dublin) about what the field of psychology can learn from genetics research, how our research theories tend to be constrained by our research tools, and his new book, "Innate".
One of the most difficult and important decisions in power analysis involves specifying
an effect size. Researchers frequently employ definitions of small, medium, and large
that were proposed by Jacob Cohen. These definitions are problematic for...
PsychBriefWhy we should no longer use Cohen's recommendations for effect sizes for power analyses: cell.com/trends/cogniti… Short and thought provoking article from Correll et al.
All psychology students are taught is levels of measurement: nominal, ordinal, interval, & ratio. But are they useful? Should we retire them?
PsychBriefNominal, ordinal, interval, and ratio. These levels of measurement are everywhere in psychology and are the foundation for many statistical analyses. But are they as essential as they are often presented? New blog post
In a classic 1978 Memory &Cognition article, Geoff Loftus explained why noncrossover interactions are removable. These removable interactions are tied to the scale of measurement for the dependent variable and therefore do not allow unambiguous ...
The direction of an association at the population-level may be reversed within the subgroups comprising that population—a striking observation called Simpson's paradox. When facing this pattern, psychologists often view it as anomalous. Here, ...
PsychBriefMost researchers believe Simpson's paradox (where the trend disappears or reverses when going from looking at the whole data set to subgroups or vice versa) is rare but the rate at which it's found and simulation studies say otherwise
