Practice your fake-spotting skills in this DIY drill. It’s from a university course named ‘Calling Bullshit’ at the University of Washington.

Each face-off pairs pictures from two databases: Real images from Flickr, fakes from thispersondoesnotexist.com, a demonstration site that shows images generated by an AI model.
To better distinguish real from fake, professors Jevin West and Carl Bergstrom suggest checking for any of several possible anomalies:
- Water splotches
- Background problems
- Eyeglasses
- Other asymmetries
- Hair
- Fluorescent bleed
- Teeth
Their course is ‘how to think critically about the data and models that constitute evidence.’
