Partitioning Friction

Dividing a resource into smaller units — wrapped portions, separate envelopes, sub-accounts — slows consumption because each partition forces a fresh decision to continue.

An everyday example

Eating fewer cookies from individually wrapped packs; spending less from money split into labelled envelopes.

What it can cost you

Sellers remove partitions to speed consumption (bulk bins, auto-refill, unlimited plans), and you remove your own by pooling.

Warning signs

  • I finished the whole thing without deciding to.
  • There was no natural stopping point.

One thing to do

Add partitions where you overconsume and notice when a product's design has removed them.
