Distortion field guide
Subgroup generalization
A result observed in a narrow group is presented as true for everyone.
How it enters the chain
The original study names its population precisely. The headline drops the qualifier, and the post applies the finding to the whole world.
How to spot it
Ask who was actually studied. Postmenopausal women in one trial is not everyone; mice are not people.
