Rands in Repose shared the link to this excellent article about how conformity at the workplace has hurt us, and ways of encouraging constructive nonconformity.
My research also shows that going against the crowd gives us confidence in our actions, which makes us feel unique and engaged and translates to higher performance and greater creativity. In one field study, I asked a group of employees to behave in nonconforming ways (speaking up if they disagreed with colleagues’ decisions, expressing what they felt rather than what they thought they were expected to feel, and so on). I asked another group to behave in conforming ways, and a third group to do whatever its members usually did. After three weeks, those in the first group reported feeling more confident and engaged in their work than those in the other groups. They displayed more creativity in a task that was part of the study. And their supervisors gave them higher ratings on performance and innovativeness. (Source)
