1) Recent research has found that emotions can be unconsciously evoked without awareness of the triggering event. Studies showed that people's emotions and words were affected by brief exposures to disturbing images, even though they were unaware of the cause.
2) Many decisions are influenced by emotional responses, even if we aren't consciously aware of them. Emotions evolved to quickly signal threats and prompt action.
3) While emotions can provide useful cues, they are an ancient system prone to "false alarms" in modern contexts. Noticing and interpreting emotions allows us to make conscious decisions rather than automatic reactions. This can help break unhelpful habits like binge eating that developed from emotional responses.
