Sunk Cost Fallacy

The sunk cost fallacy is continuing an initiative because of what's already been invested in it, rather than what it will cost or return going forward.

Example

A team keeps funding a struggling internal tool because of the six months already spent building it, even though a fresh evaluation says it's not worth finishing.

Why it matters

Naming the pattern makes it possible to catch a "we've already invested so much" argument and evaluate the decision on its actual future merits instead.

Limits and cautions

Past investment isn't always irrelevant. It can be a legitimate signal of momentum or learned expertise, not automatically a fallacy to dismiss.

Relevance to Stelaah

Stelaah's project financials can show a project's forward cost and expected return separately from what's already been spent, supporting a clearer decision.
