Quick check

Are the categories being used carefully, or are unlike things being treated as alike?

Why it misleads

A fuller explanation of how the fallacy works and why it can look persuasive.

A vivid case can motivate investigation, but it does not by itself justify a population-level conclusion.

That's like saying...

Instead of leading with the label, this analogy answers the shape of the reasoning move directly so the mistake is easier to see in plain language.

Fallacious claim

One rideshare driver ran a scam on me, so rideshare drivers are crooks.

That's like saying...

That's like catching one salmonella outbreak at a restaurant and concluding restaurants are crooks. A bad individual case is being used to condemn the whole group.

Caveat

This label is easy to overuse. The point here is not to call every weak argument by this name, but to reserve it for the exact misstep it describes.

Common misapplication

Do not use this label every time people disagree about definitions or categories. It applies when the category boundaries themselves are distorting the reasoning.

Use the label only when...

Use this label only when a negative trait found in one member of a group is used to condemn the group as a whole. If the real problem is that a negative generalization about a group is used as if it settled the character or behavior of a specific member of that group, the better label is Bottom-up condemnation.

Where the slip happens

The trouble begins when a negative trait found in one member of a group is used to condemn the group as a whole.

How to use the stages

Move through Frame -> Blur -> Confusion -> Repair in order, compare each stage to the current example, and stop as soon as the later step adds more than the earlier one has earned.

What the repair step asks

Are the categories being used carefully, or are unlike things being treated as alike?
