## What it is

Rejecting a workable option because it falls short of an ideal that is not available.

## In the wild

> The fix does not solve everything, so it is useless.

## How to answer it

Compare the option to the real alternatives, not to perfection.

## Origin and naming

The term was coined by the economist Harold Demsetz in 1969, criticising policy arguments that compared real institutions to an idealized 'nirvana' rather than to actually available alternatives. The idea itself is older — Voltaire wrote in 1772 that 'the perfect is the enemy of the good' — and the fallacy is what happens when that warning is forgotten.

## More places it shows up

- The new ticketing system will not cut support volume to zero, so the migration was a waste.
- A helmet does not protect against every injury, so there is no point in making cyclists wear one.
- The mentorship program only helped some juniors, so it failed and should be scrapped.
- This filter does not catch every scam, so it cannot be part of the answer.

## How to spot it

- The option on the table is judged against an imagined one, never against the real alternatives.
- Any residual problem, however small, is treated as a verdict on the whole proposal.
- Ask what the speaker prefers instead, and the answer either does not exist or quietly scores worse.
