Sunk-Cost Effect

The ticket is paid for and the play is dull. How much of that money can your next hour recover?

01 / SUMMARY

In short

A sunk cost cannot be recovered, yet it can keep shaping later choices. People persist to avoid feeling that time, effort, or money was wasted even when continuing worsens future outcomes.

03 / SCENE

In the wild

A team keeps an unworkable project alive because it already spent six months on it, although a new option promises better results from now on.

04 / LIMIT

The limit

Quitting is not always wise; past investment may reveal information or build capabilities that genuinely alter future returns.

FINAL NOTE

What remains

Compare only the costs and benefits each option can produce from this point forward.
