Pro tip, folks: if you make a figure for a publication, don’t just hand the copyright over to the publisher. Post it on OSF first and then give yourself permission to use it in the first publication and then all future publications. That way, no permissions issues.

The tendency to lie is a trait that is consistent across time and settings. If you know someone who lies to other people... they are probably lying to you as well. Another great paper by @IsabelThielmann and colleagues. psycnet.apa.org/record/2025-…
