Masked-Man Fallacy
Assuming that if you don't know someone's identity, you can't know facts about them, even if you already do.
This fallacy confuses knowledge of a person's identity with knowledge of facts about them. It happens because we conflate knowing 'who' someone is with knowing 'what' is true of them. For example, you might know a man in a mask is your brother, but mistakenly think you can't know he's in the room because you don't know it's him under the mask.
Recognising a definition is not the same skill as spotting it.
Two scenarios from the app, with distractors drawn from the same family of biases — which is what makes them hard.
A news article quotes an 'anonymous insider.' You dismiss the entire story, stating, 'If they won't say who they are, the information can't be reliable.'
After a blind date, Mia tells her friend, 'I had a wonderful time, but I can't say he's funny because I don't know his last name.'
Biases rarely arrive alone.
