We don’t choose between experiences, we choose between memories of experiences. Even when we think about the future, we don’t think of our future normally as experiences. We think of our future as anticipated memories.

We have a very narrow view of what is going on.

Mood evidently affects the operation of System 1: when we are uncomfortable and unhappy, we lose touch with our intuition. These findings add to the growing evidence that good mood, intuition, creativity, gullibility, and increased reliance on System 1 form a cluster. At the other pole, sadness, vigilance, suspicion, an analytic approach, and increased effort also go together. A happy mood loosens the control of System 2 over performance: when in a good mood, people become more intuitive and more creative but also less vigilant and more prone to logical errors.

To better avoid errors, you should talk to people who disagree with you and you should talk to people who are not in the same emotional situation you are.

It doesn't take many observations to think you've spotted a trend, and it's probably not a trend at all.
