Many analysts are not always equal analysts "Should every analyst's contribution be weighted equally?" From "Ten Strategies To Improve Many-Analysts Studies" by Alexandra Sarafoglou, @balazsaczel.bsky.social et al. Preprint: osf.io/preprints/ps... #MetaSci
Strategy 4. Integrate analytic quality and expertise. As many-analyst approaches mature, there may be good reasons to introduce more nuance to the wisdom of the crowds principle. Should every analyst’s contribution be weighted equally? How can we account for pre-existing differences between analysts —such as varying levels of expertise in the research topic, methodology and statistics, or differences in the time available to dedicate to the analysis— in a way that supports the overall quality of the project? Rather than solely using these factors as potential exclusion criteria (see e.g., Aczel et al., 2021; Gould et al., 2025), they could also serve as grounds for giving greater weight to submissions from highly rated teams. One could make a strong case for taking factors such as subject-matter and methodological expertise into account when weighing the contributions of individual analysts (see e.g., Aczel et al., 2021). This can be done either when calculating an overall meta-analytic effect size across teams (Bartoš, Hoogeveen, et al., 2025) or by incorporating the weights into a meta-regression analysis

@mikemorrison.bsky.social will be sharing how #scientists and #SciComm folks can combine design and psychology principles to create engaging visual science communication tools. Join this Friday, Oct 17 @ 2pm ET for this FREE webinar. Sign up for Zoom link. waterwhys.org/seminar/fall...
Flyer for the 2025 Visual SciComm Seminar speaker Mike Morrison. A Water Whys logo is at the top left with a question mark embedded in an upside down water droplet. At the center is Mike's picture. The background in the lower half is reminiscent of waves. 

Friday, October 17, Mike will be the second speaker in the Water Whys Visual SciComm Seminar Series, talking about "Design for Scientists: Help people pay attention to research and love it!"
 
Design and psychology principals are at the core of making visual communication (slides, posters, research reports — anything) engaging. In his presentation, designer and psychologist, Mike Morrison will explore this through games and silly graphics. You’ll see data from eye tracking and other studies beautifully illustrating how the power of good design can make science move faster and be more pleasant to learn (even for scientists). And you’ll get a glimpse into the future of scientific publishing. In the end, you’ll learn immediately-applicable tips that will help you design things that impact more people, and get your science message out further.
 
This FREE virtual talk is from 2-3pm ET / 11am-noon Arizona Time and is open to everyone.
 
Register to get the Zoom link.
