These and other cool results (such as the author-provided excuses for why they cannot share their data or whether authors that provide data on their websites are any different) can be found here 👉👈.

Speaking of p-hackers possibly being detected, we don't find that administrative data, which might be the hardest for a later researcher to get hold of, performs pretty well compared to other data types!

But does this increased potential detection of p-hacking (by later researchers perhaps using the shared data) affect whether it is present? Multiple tests find no difference.

Encouragingly, after a journal implements a data-sharing policy, the share of articles providing no materials drops, while the share of articles providing full access increases.

Do data-sharing policies or data type affect p-hacking?. (. In a new working paper with Abel Brodeur and Carina Neisser (@NicerCarina) using 1000+ economics articles over 2002-2020, we find data policies have no effect on the prevalence of p-hacking. A 🧵.
