Open science and qualitative research: Yes, we can do this!

I’m currently at the 70th Annual Conference of the International Communication Assocation, where this year’s theme is Open Communication.

Besides, and maybe less well-known, small samples also increase the probability of finding extreme results, which leads to a literature full of effect sizes that are artificially inflated (e.g., Button et al., 2013).
