It’s probably a natural reaction whenever something negative happens to assume the worst motives behind it. In corporate life this usually means assuming that someone has purposely done something despite us or because they didn’t care about how it would impact us. My philosophy on this is that if I don’t know someone has ill-intentions, I will assume they don’t. In areas that I don’t control, the most likely explanation for a negative outcome that impacts me is that a mistake has been made, rather than someone has done something intentionally. In other words, if in doubt, I assume there has been cock up rather than a conspiracy.
