Judgement is something we are usually keen to get good at, to have been seen to exercise good judgement, to be a good judge of character. Discerning good from bad is surely a good thing? Knowing when something has been done well and when it hasn't - isn't that the first step in progress?
It is seen as a skill in management. Judging who has done better, who deserves reward, who deserves punishment.
But judgement has a dark side - being judgemental. Judging others and finding them wanting is something we all indulge in. Whether it is political extremes projecting their own dysfunctional nastiness onto each other, or religions judging other religions to be the work of the devil. It makes us feel good to judge others. We can feel superior. We can ignore our judging of ourselves, the pain of finding ourselves wanting.
Like everything else the online world can amplify judgement. It can speed it up and increase its scope. We can work out good from bad faster but we can also judge more people for their actions and we can compare ourselves unfavourably against more people whom we deem successful.
We all do it, and I am as bad as the next person. Maybe we should try not to.
