Over time I have come to realize that you can decipher how well a person understands a topic by how simply and clearly they explain it. They know how to go from points A, to B, to C, and so on. That does not necessarily mean, however, that they are unaware of the nuances or are unable to delve into them. They simply possess a clarity of thought and aptly demonstrate it.
But there are also those with a particular disposition that causes them to either rule out topics as being “too complicated” for their audience or habitually goes from points A, to G2, to B1, to C4, to X, and so on, to make their point. I suspect the latter individuals don’t actually know what they’re talking about and try to hide it behind a continuous barrage of blather in hopes of beating their audience into mental submission.
I am afraid that, quite often, I fall into this latter category. Whenever I say that something is really complicated or explain something in a very convoluted way (as I’ve described above), it is probably a dead giveaway that I don’t know what I’m talking about.
