You forgot their birthday again.
You can't remember if they hate cilantro or just avoid it. The group chat went quiet months ago.

You have hundreds of contacts. But how many do you actually know anymore?

Social media creates the illusion of connection while relationships quietly fade.

You're not a bad friend.
Your brain wasn't built for this.

Dunbar's 150 Your brain's natural limit for meaningful relationships
Living Journal

Your Brain Has a Limit. Dunbar Proved It.

Your neocortex can only track so many relationships. Beyond 150, we can't remember who's who and who knows whom.

From Primates to People

Robin Dunbar discovered something remarkable: humans can only maintain meaningful relationships with about 150 people. Not because we're lazy. Because our brains literally have a capacity limit.

Dunbar studied primate brain size and group size, finding a pattern. Bigger neocortex = bigger social groups. Humans? We max out at 150.

"The 150 are the people whose death would matter to you." — Robin Dunbar

Throughout history, human groups naturally organize around this number. This isn't random. It's biology.
