Blame, Responsibility and Solutions. These are not necessarily connected, so don’t get them mixed up.
When something goes wrong it’s a knee-jerk reaction to blame.
When something goes wrong, there’s a natural reaction to avoid accepting responsibility.
These two are interrelated, in that people often conflate blame and responsibility. They are sometimes related, maybe (and if that’s important to you), but you can be responsible without being the cause of a problem.
You can also take the blame without being the cause of a problem (many people have it forced on them), and therefore not responsible for it. That’s because carelessly thinking people and systems seem to need to place blame above all else.
Then there are solutions, and you don’t need blame – nor to know the cause of something – to offer a solution.
