So.... Ask contributors to any given group project what their contribution was. The total will almost always be >100%. Ask about share of blame, I reckon it will always be <100%. Organisational culture and group psychology tend to prop up such fallacies, allowing everyone to overestimate and underestimate their contribution to success and failure... these accumulate to organisational fallacies over time. Venkatesh Rao once called the lies cumulating as a result of this "organisational dark matter." Lies beget lies. If a team is responsible for 180% of the success and 45% of the failure... something has to account for that. External factors played a role. Someone else failed. The project is actually more successful than it is. Etc. A lot of group psychology is just this... ways of supporting group beliefs.
