NYU study: capping AI memory at 4 slots makes it a far better stand-in for real humans

New research from NYU's Center for Data Science shows the counterintuitive key to making AI better at imitating humans is limiting its memory: capping a model's memory at 4 slots makes it a far better stand-in for a real person.

The work was led by CDS Faculty Fellow Nick Tomlin, PhD student Michal Huang, and Associate Professor Tallinzen, with former NYU Data Science master's student Qihan Wang playing a major role.

The finding is a useful signal for building human-behavior simulations and agent-based social modeling: perfect recall isn't necessarily an advantage — a bounded memory window better matches real human cognitive limits.
