>They may write well on a subject but that doesn't mean they know anything. There's a bit to unpack here. Being articulate is orthogonal to being skilled. That is, it's widely understood to be harder to explain what you do than to actually do, often by an order-of-magnitude. Articulation can itself be considered a skill, but I think it's practical to ignore that in a conversation like this - with the sole exception of when articulation takes precedent over skill, as is the case with bullshitters and sophists. This is an error mode, similar to how any valuable quality can be overdone and loose it's healthy relationship to other qualities.
