self-serving bias

At one company we know, for example, leaders were asked to estimate how much time they spent tiptoeing around other people’s egos: making others feel that “my idea is yours,” for instance, or taking care not to tread on someone else’s turf. Most said 20 to 30 percent. Then they were asked how much time they spent tiptoeing around their own egos. Most were silent. Psychology explains this dynamic as a very predictable, and very human, “self-serving bias.” It involves viewing our own actions favorably and interpreting events in a way beneficial to ourselves. This explains why 25 percent of students rate themselves in the top 1 percent in their ability to get along with others. It’s why, when couples are asked to estimate their contribution to household work, the combined total routinely exceeds 100 percent.
