    Key idea 1 of 9

    Your happiness can interfere with your performance and accuracy.

    Nowadays, management goes by the mantra that an upbeat mood translates to business success. But while mirthful and content people do get better customer and supervisor evaluations, that doesn’t objectively mean that they are performing better.

    For instance, while they might be likeable, happy people are less persuasive.

    If you want to persuade others, then you have to communicate your message in a detailed and concrete way. However, happy people tend to focus on the big picture at the expense of the tiny details. Consequently, their arguments are less nuanced and concrete.

    Indeed, this can be seen in a number of studies on the persuasiveness of upbeat people:

    In these studies, “happy” and “unhappy” people were asked to create arguments about issues ranging from the allocation of tax dollars to the existence of soul mates. In all these studies, unhappy people’s reasoning was judged as 25-percent more convincing than those of happier participants.

    What’s more, happy people are more easily deceived and more likely to “recall” false facts than others.

    As we’ve already seen, people tend to be less interested in details when they’re happy. But if you want to spot deceit, then you’ll have to look for very subtle cues. This became obvious in one study in which participants were asked to identify liars and honest people in a series of videotapes:

    The tapes showed people denying that they had stolen something, only half of whom were telling the truth. Happy participants were able to identify the liars only 49 percent of the time, while unhappy people detected 62 percent of the frauds.

    In other experiments in which people had to recall facts or words they’d been presented with before, the happiest among them were the most prone to “recall” items they hadn’t even been shown!

    Clearly, happy people are both less persuasive and more gullible. So, how happy do you want your lawyer to be?
