What happens when there is a "culture of blame" is that innovation falls to zero (or lower). When people are scared of being blamed for things, and potentially also fired with little prospect of re-employment, then they just stick very rigidly to whatever they believe their job description to be, and never seek to explore new possibilities. The classic phrase is "it's more than my job's worth". In a culture of blame anything new or different is seen as bad, and to be avoided at all costs, because the unknown nature of the new might also bring blame with it.
