Not only on a professional level, but on a societal level we seem predisposed to always want to blame someone if something doesn’t go right. This is unfortunate. All we gain from this is some false level of comfort.
There are plenty of times when someone isn’t to blame for something that has happened. I would argue that more times than others, things fail for a multitude of reasons where many each have a small role in what happened. All we could really say is that the situation went bad.
Yet even in these cases we want to blame someone. We have an extremely hard time to accept collective failure and want to find the scapegoat, to little real effect. Blaming such a scenario on just one single person is ultimately only going to make us feel marginally better and will definitely not go to any lengths ensuring that it doesn’t happen again.
Blaming someone for something that didn’t go to plan is natural and comforting, but we should take care in overdoing it. Finding a scapegoat when there is in fact no clear one is contra-productive and will only make things far worse. A lot of the time a series of unfortunate consequences just happen without any specific person actually being at fault. We should learn to accept this.
