Zofia lives in an apartment complex with a busy courtyard where they eat dinner in the evening when the weather is nice. In the last few weeks, they noticed the same unfamiliar person hanging out in the courtyard minding their own business. Zofia assumes the person is a new resident and doesn't mention them to anyone. However, Zofia is later shocked to learn that the person was a thief who was casing the building to see whose light stayed off at night. When asked why they never brought up the interloper, Zofia replies, "Well, nobody else seemed weirded out by seeing them, so I just assumed their being around was fine!" What kind of thinking is this an example of?
