Do we really keep score in our friendship? See what @AthenaAktipis and I have to say about why this isn’t always the case

SOLD OUT! I'm giving "The Science of Friendship" in the @lecturesontap series in LA on Dec 2! These are amazing events. (For scholars, they can help remind the public why what we do it worth funding.)

What an exciting new platform to talk about all of the cool things that can influence us. https://t.co/XlAmxiUrQc I’m personally excited for the ones on hijacking and how it might not be only bad! @AthenaAktipis

💞 Friendship isn’t about keeping score. It’s about helping when it counts. In our new @ConversationUS article, @JessicaDAyers & I explore why true friendship works like risk-pooling, not exchange. Read here 👉 https://t.co/nw4T5ifwLU #Friendship #Psychology

Is it bad to be excited about new data before finishing old projects? Asking for a friend …. (Also @Jay_Park93 you make the cooled graphs)

Glad to have had the chance to pitch why we need to research friendship to @BoiseState stake holders as an ASSERT ( https://t.co/N0fR3jXng2) fellow at today’s pitch event.

Best part of being a professor? Having my lab listen to Evolutionary Psychology (the podcast) with @DavidPinsof and @DavePietrasz so I have an excuse to listen too!

We know a lot about ovulatory hormones in early reproductive life - but what about near menopause? Read more about my RA’s research project here

How do people know whom, and how much, to help? we (@JessicaDAyers @lee_cronk Daniel Balliet Jeremy Koster & @AthenaAktipis) tackle this question among the Mayangna of northern Nicaragua, who rely primarily on horticulture for subsistence 🧵(1/10).

Excited to announce that I won the Feminist Evolutionary Psychology Society best faculty talk at @NEEPSoc this year!

APE lab represented at NEEPs 2025!

Why do our friendships feel so vital? I wrote a short piece for @JessicaDAyers’ lab blog. It discusses why evolutionary psychology is critical for understanding complex social phenomena like friendship and provides an introduction to evolutionary social psychology. Read it

Some promising trends in the psychology replication crisis since 2004: - Fewer studies publish weak p values (.01 < p < .05) - Studies with weak p values are less likely to get cited - The % of weak p values (26%) is now roughly what we would expect from studies with 80% power.

After a great @HumBehEvoSoc panel on friendship, I thought it was a perfect time to share @benjamin_zubaly’s thoughts on why evolutionary theory is needed to understand friendships
