  • Downplayed: Alice sees Bob staring at Claire's chest and assumes he's blatantly checking her out. Really he's just astonished by Claire's ugly shirt.
  • Justified:
    • Alice's previous boyfriend cheated on her, so she's more likely to assume other guys are cheating.

  • Invoked: When Bob believes Alice is losing interest in him, he starts hanging around with Claire to make her jealous.
  • Exploited: Charlie tries to confirm Alice's suspicions. So that she will leave Bob & start going out with him.
