Hasty Generalisation Fallacy: Duchess Meets the Vet

Oh no. It's the 10th. It's time for Duchess to go to the Vet!

Bruno points at a calendar with VET circled as Duchess stares up at it in absolute horror
Duchess pushing against the car doors screaming as Bruno is trying to get her in the car to take her to the vet
Duchess screams Torturers all of them in the back seat as Bruno drives her to the vet
Duchess is relieved as she sees cats and dogs relax happily at the vet as dog vets in white coats tend to them gently

She crashed out on the way there, but turns out it wasn't so bad after all! 

Flip out, scream and cry with our Hasty Generalisation Activity Pack.

Hasty Generalisation in a Nutshell

Duchess didn't come to her conclusion through careful reasoning. She came to it through one (possibly dramatic) experience, a strong feeling, and an iron determination not to be proved wrong.

That's the Hasty Generalisation - also called hasty generalization. You take a small sample of evidence and treat it as if it represents everything. One bad vet visit becomes: all vets are torturers. One rude customer becomes: all customers are rude. One failed experiment becomes: this never works.

The problem isn't that Duchess had a bad experience. The problem is that she concluded, from that experience, something absolute. And absolute conclusions - especially fast ones - are almost always wrong. Fortunately for Bruno's upholstery, the vet turned out to be fine.
