Path Dependence

“An early choice can make repetition cheaper and every later alternative more expensive.”

01 / PLAINLY

What it means, plainly

Path dependence explains how early choices, investments, and feedback can make an institutional route easier to repeat.

02 / CONTEXT

A little more

Path dependence studies how sequences, feedback, and increasing returns make institutional choices durable. Early moments and critical junctures can channel outcomes without determining them forever.

03 / WHY IT MATTERS

Why it matters

It explains persistence without treating history as destiny or the first choice as irreversible.

04 / EXAMPLE

A familiar example

An old administrative format persists because archives, training, and vendors were built around it.

05 / LIMIT

What it does not mean

It does not make the first choice irreversible, and invoking history alone does not explain a mechanism.

06 / NOTICE

Notice it in your day

Choose an old format or process and list the archives, training, vendors, and habits built around it. Mark the investment that makes change costly.

FINAL NOTE

The idea worth keeping

Find the investment or feedback that makes an inherited path easiest to repeat.

QUESTIONS / 02

Questions people still have
