How we change what others think, feel, believe and do
Our judgments are not cold and logical: they are biased by our moods. When we are in a good mood, we see the world in a more friendly light, and our judgments are more positive. Likewise, when we are grumpy we evaluate things around us as being bad.
This can create a spiral, as positive judgments lead to positive moods. They also lead to positive moods in others, who then infect us back again.
Mood can be affected by such as movies, music and comments of others.
Isen and colleagues gave some people in the street small gifts. Another person then asked them to participate in a 'consumer survey' where they asked about how satisfied they were with their televisions, cars, etc. People who had receive the gift were more positive.
Depressed people see the world as unfriendly and threatening, which keeps them depressed.
If you want someone to make a decision, either wait until they are in a supporting mood or work to get them into that mood.
Before making decisions, consider the mood you are in and how this might affect your decisions. After the decision also review the affect of your mood. Consider how you got in the mood and who influenced this.
