"False perceptions.
Our research indicates that a surprisingly large number of managers are unable to objectively judge how badly (or well) their firms are run. (Similar biases show up in other settings. For example, 70% of students, 80% of drivers, and 90% of university teachers rate themselves as “above average.”)
.
Consider the average response we got to the question “On a scale from 1 to 10, how well managed is your firm?,” which we posed to each manager at the end of the survey interview. Most managers have a very optimistic assessment of the quality of their companies’ practices. Indeed, the median answer was a 7. Furthermore, we found zero correlation between perceived management quality and actual quality (as indicated by both their firms’ management scores and their firms’ performance), suggesting that self-assessments are a long way from reality.
.
This large gap is problematic, because it implies that even managers who really need to improve their practices often don’t take the initiative, in the false belief that they’re doing just fine.
.
In a variant of this problem, managers may overestimate the costs of introducing new practices or underestimate how much difference they could make."
