Get involved


Catch us at these conferences (and other news)!


We are planning to hold the first ManyPrimates symposium sometime after the pandemic at the MPI for Evolutionary Anthropology in Leipzig, Germany.

Authorship Guidelines

As a large scientific collaboration that aims to be inclusive, we developed guidelines and criteria for how to assign authorship to individuals involved in ManyPrimates projects.

Ethics Guidelines

We developed ethical guidelines for procedures and participation in ManyPrimates studies.


We encourage everyone who is interested in primate cognition to get involved. Access to primates is NOT a prerequisite.

Review of Primate Cognition Research

We conducted a systematic review of primate cognition research published between 2014 and 2019 to quantify sample sizes and identify sampling biases. Based on this survey we outline why many research questions can only be addressed through large-scale collaboration.


As a proof of concept, this study was a first step towards building an infrastructure that facilitates large-scale collaboration in primate cognition research. In this pilot study, we conducted a short-term memory task with 176 primates from 12 species and 11 sites.

ManyPrimates 1: Short-Term Memory

The first ManyPrimates project is a continuation of our pilot study. We collected data from 400+ primates from 40+ species and almost 30 sites in order to make meaningful inferences about the evolution of short-term memory abilities in the primate lineage.

Status: Analysis & writing

ManyPrimates 2: Delay of Gratification

For this project, we will assess primates' ability to resist the temptation of an immediate reward in order to receive a larger or better reward later on.

Status: Data collection (soon!)

ManyPrimates 3: Inference by Exclusion

For this project, we will assess primates' ability to make choices by excluding alternative options.

Status: Writing (Stage 1 Registered Report)
